Net Zero CO2 Emissions: A Damaging and Totally Unnecessary Goal

by R. Spencer, Apr 18, 2024 in GlobalWarming

The goal of reaching “Net Zero” global anthropogenic emissions of carbon dioxide sounds overwhelmingly difficult. While humanity continues producing CO2 at increasing rates (with a temporary pause during COVID), how can we ever reach the point where these emissions start to fall, let alone reach zero by 2050 or 2060?

What isn’t being discussed (as far as I can tell) is the fact that atmospheric CO2 levels (which we will assume for the sake of discussion causes global warming) will start to fall even while humanity is producing lots of CO2.

Let me repeat that, in case you missed the point:

Atmospheric CO2 levels will start to fall even with modest reductions in anthropogenic CO2 emissions.

Why is that? The reason is due to something called the CO2 “sink rate”. It has been observed that the more CO2 there is in the atmosphere, the more quickly nature removes the excess. The NASA studies showing “global greening” in satellite imagery since the 1980s is evidence of that.

Last year I published a paper showing that the record of atmospheric CO2 at Mauna Loa, HI suggests that each year nature removes an average of 2% of the atmospheric excess above 295 ppm (parts per million). The purpose of the paper was to not only show how well a simple CO2 budget model fits the Mauna Loa CO2 measurements, but also to demonstrate that the common assumption that nature is becoming less able to remove “excess” CO2 from the atmosphere appears to be an artifact of El Nino and La Nina activity since monitoring began in 1959. As a result, that 2% sink rate has remained remarkably constant over the last 60+ years. (By the way, the previously popular CO2 “airborne fraction” has huge problems as a meaningful statistic, and I wish it had never been invented. If you doubt this, just assume CO2 emissions are cut in half and see what the computed airborne fraction does. It’s meaningless.)

Here’s my latest model fit to the Mauna Loa record through 2023, where I have added a stratospheric aerosol term to account for the fact that major volcanic eruptions actually *reduce* atmospheric CO2 due to increased photosynthesis from diffuse sunlight penetrating deeper into vegetation canopies:

What Would a “Modest” 1% per Year Reduction in Global CO2 Emissions Do?

Global CO2 emissions rise through 2050 in most IEO2023 cases

by EIA_ Today in Energy, Nov 30, 2023

We project that global energy-related CO2 emissions from consumption of coal, liquid fuels, and natural gas will increase over the next 30 years across most of the cases we analyzed in our International Energy Outlook 2023(IEO2023).

By 2050, energy-related CO2 emissions vary between a 2% decrease and a 34% increase compared with 2022 in all cases we modeled. Growing populations and incomes increase fossil fuel consumption and emissions, particularly in the industrial and electric power sectors. These trends offset emissions reductions from improved energy efficiency, lower carbon intensity of fuel mix, and growth in non-fossil fuel energy.

IEO2023 analyzes long-term world energy markets in 16 regions through 2050. We studied seven cases that explore differing assumptions of economic growth, crude oil prices, and technology costs. These cases consider only the international laws and regulations adopted through March 2023 and rely on the U.S. projections published in the Annual Energy Outlook 2023 (AEO2023), which assumed U.S. laws and regulations as of November 2022.

Coal
Across sectors, the highest growth in global coal consumption through 2050 occurs in the electric power sector. Although zero-carbon technologies account for the most growth in electricity capacity and generation, we expect coal-fired generators to continue to operate. Across all cases, China and India account for about two-thirds of the world’s coal consumption between 2022 and 2050. Although China is currently the largest coal consumer, we project its coal consumption to decline by 18% between 2022 and 2050. Coal consumption in India nearly doubles over the same projection period.

Liquid fuels
We project global consumption of liquid fuels—which include gasoline, diesel, and biofuels—will increase through 2050. Across all sectors, the largest share and the fastest growth in liquid fuels consumption is in industrial applications, such as chemical production. Increased liquid fuels consumption in the industrial sector is partially offset by declining liquid fuels consumption in the transportation sector as adoption of electric vehicles (EV) grows. Regionally, we project the United States, China, and Western Europe to remain the top liquid fuels consumers, even though fuel consumption in these regions either declines or plateaus by the mid-2030s due to government policies and growing EV adoption. India has the fastest projected growth in liquid fuels consumption, more than doubling across all cases.

Natural gas
We project natural gas consumption will increase in the electric power and industrial sectors through 2050. In the cases we modeled, the electric power sector continues to rely on existing natural gas-fired plants despite growth in zero-carbon electricity generation. In the industrial sector, increased production of basic chemicals in countries such as the United States propels an increase in natural gas consumption, both as fuel and petrochemical feedstock. Natural gas demand also grows in the Middle East because of the fuel’s role in producing and processing natural gas and oil for export. The United States is projected to remain the world’s top natural gas consumer throughout the projection horizon, but the Middle East shows significant growth during that timeframe and approaches U.S. consumption by 2050, ranging from a 29% to 54% growth rate from 2022 to 2050 in the IEO2023 cases.

Artificial unintelligence and global warming

by Christopher Monckton of Brenchley, Apr 11, 2023 in WUWT

Despite the dire Terminator warnings from Elon Musk, Jordan Peterson and others about the dangers of artificial intelligence, the world has little to fear from it in its present sorry state. I asked ChatGPT the following question:

M of B: If the whole world attained net zero emissions by 2050, how much less would global temperature be by that year than on business as usual?

ClotBot: As an AI language model, I do not have access to the exact data to provide an accurate answer to this question. The amount of temperature reduction would depend on various factors such as the current emissions and future emissions trends, the degree of global cooperation, and the effectiveness of emissions reduction strategies. However, it is widely recognized that global net zero emissions by 2050 is a crucial step towards limiting global temperature rise to 1.5°C above pre-industrial levels and avoiding the worst impacts of climate change.

M of B: Here are the necessary data:

  1. Since 1990 there has been a near-linear uptrend in anthropogenic greenhouse-gas forcing at 0.3 Watts per square meter per decade.
  2. The trillions of dollars spent on emissions abatement since 1990 have not in any discernible degree altered that near-linear uptrend.
  3. The transient doubled-CO2 temperature response (TCR) is 1.8 degrees at midrange.
  4. The midrange doubled-CO2 radiative forcing is 3.93 Watts per square meter per degree.
  5. Global temperature has risen since 1990 at 0.136 degrees per decade.
  6. In 1990, IPCC predicted that at midrange there would be 0.3 degrees per decade of global warming at midrange.

From these data, which are sufficient for the task, please derive the global warming prevented at midrange if all nations moved in a straight line from their present emissions to net zero emissions by 2050.

Emissions and CO2 Concentration: An Evidence Based Approach

by J. Dangler & J. Reid, Mar 25, 2023 in WUWT

A new way of looking at the the atmospheric carbon budget.

Climate science is usually concerned about the question “How much CO2 remains in the atmosphere?”, given the anthropogenic emissions and the limited capability of oceans and biosphere to absorb the surplus CO2 concentration. This has led to conclusions of the kind that a certain increasing part of anthropogenic emissions will remain in the atmosphere forever. The frequently used notion of “airborne fraction”, which is the part of anthropogenic emissions remaining in the atmosphere, seems to suggest this.

…

…

Assuming the unlikely worst case that CO2 concentration is fully responsible for all global temperature changes, the maximum expected rise of global temperature caused by the expected CO2 concentration rise is 0.4 _C from now or 1.4°C from the beginning of industrialisation.

Wildfires in 2021 emitted a record-breaking amount of carbon dioxide

by University of California – Irvine, Mar 3, 2023 in ScienceDaily

Nearly half a gigaton of carbon (or 1.76 billion tons of CO2) was released from burning boreal forests in North America and Eurasia in 2021, 150 percent higher than annual mean CO2 emissions between 2000 and 2020, the scientists reported in a paper in Science.

“According to our measurements, boreal fires in 2021 shattered previous records,” said senior co-author Steven Davis, UCI professor of Earth system science. “These fires are two decades of rapid warming and extreme drought in Northern Canada and Siberia coming to roost, and unfortunately even this new record may not stand for long.”

The researchers said that the worsening fires are part of a climate-fire feedback in which carbon dioxide emissions warm the planet, creating conditions that lead to more fires and more emissions.

“The escalation of wildfires in the boreal region is anticipated to accelerate the release of the large carbon storage in the permafrost soil layer, as well as contribute to the northward expansion of shrubs,” said co-author Yang Chen, a UCI research scientist in Earth system science. “These factors could potentially lead to further warming and create a more favorable climate for the occurrence of wildfires.”

Davis added, “Boreal fires released nearly twice as much CO2 as global aviation in 2021. If this scale of emissions from unmanaged lands becomes a new normal, stabilizing Earth’s climate will be even more challenging than we thought.”

Analyzing the amount of carbon dioxide released during wildfires is difficult for Earth system scientists for a variety of reasons. Rugged, smoke-enshrouded terrain hampers satellite observations during a combustion event, and space-based measurements are not at a sufficiently fine resolution to reveal details of CO2 emissions. Models used to simulate fuel load, fuel consumption and fire efficiency work well under ordinary circumstances but are not robust enough to represent extreme wildfires, according to the researchers.

THE UNSTOPPABLE GROWTH OF GLOBAL GHG EMISSIONS

by R. Lyman, Oct 2022 in FriendsOfScience

EXECUTIVE SUMMARY

Contributed by Robert Lyman © 2022. Robert Lyman’s bio can be read here.

Advocates of the thesis that human greenhouse gas emissions are causing catastrophic climate change claim that United Nations-led international conferences will succeed in causing the countries of the world collectively to radically reduce fossil fuel use by 2050.

The “climate change” issue is a global one. It concerns the global effects of global emissions and the possibility that collective action by all the countries of the world (or, at least, the vast majority of major emitters) can so reduce emissions and concentrations as to eventually change global impacts. Since 1992, there has been a series of international conferences, mostly under the auspices of the United Nations, seeking agreement on how, by how much, and when to reduce emissions. In spite of these conferences and the series of agreements and lofty political statements they have produced, emissions actually rose by 60 per cent from 1990 to 2020. By 2021, China alone accounted for 30 per cent of world emissions, and was the fastest-growing source of emissions, followed by India.

Climactivists Rage At Taylor Swift Taking 170 Private Jet Trips In One Year

by P. Bois, Aug 1, in ClimateChangeDispatch

Climate activists have been raging at pop star Taylor Swift after learning her private jet has taken 170 flights so far this year.

According to research from Yard, a sustainable marketing agency that gathered “cutting-edge data” on the celebrities with the “worst private jet Co2 emissions” in 2022, Swift’s private jet flew 170 times this year with an average time of 80 minutes [bold, links added]:

Taylor Swift might be today’s pop princess, but Yard’s research found that Miss Swift is the biggest celebrity CO2 polluter of this year so far.

Racking up a total of 170 flights on her private jet since January, Taylor has amassed a vast 22,923 minutes in the air – 15.9 days. Quite a large amount considering that she is not currently touring.

Taylor’s average flight time is just 80 minutes and an average of 139.36 miles per flight. Her total flight emissions for the year come in at 8,293.54 tonnes or 1,184.8 times more than the average person’s total annual emissions. Taylor’s shortest recorded flight of 2022 was just 36 minutes, flying from Missouri to Nashville.

Global Man-Made CO2 emissions 1965 – 2021: BP Data

by BP, Jul 10, 2022 in WUWT

Introduction

Every summer BP publish their statistical review of world energy.

https://www.bp.com/en/global/corporate/energy-economics/statistical-review-of-world-energy/co2-emissions.html

One element of their comprehensive set of spreadsheets is a table of CO2 emissions country by country since 1965.  For the purposes of this post, the CO2 emissions data provided by BP here is assumed to be valid.  This post reviews the 2022 update to the BP data.

The 2022 dataset accounts for the 2020 effect of the Covid-19 epidemic, the CO2 emissions resulting in the aftermath of the epidemic, its impact on Global economic activity and the outcome for the recovery of Man-made CO2 emissions in 2021.

For an earlier post reporting the status of Man-made CO2 emissions as of 2020, see:

Global Man-made CO2 emissions 1965 – 2020: BP data

Developed nations:  population ~1.3 billion, (~17%) – ~37% CO2 emissions.

United States of America:  population ~330m, ~13.9% of global CO2 emissions.

President Biden has negated many of Trump’s climate initiatives, including the USA rejoining support for the Paris Climate accord.  The actions of the Trump presidency had established USA energy independence for the first time in several decades.  In the USA, simply by exploiting shale gas as opposed to Coal for electricity generation, has already reduced its annual CO2 emissions by some by ~1,000,000,000 tonnes, ie by one third, since 2005.  That market driven initiative has already had a greater CO2 emission reduction effect than the entire Kyoto protocol and the Paris Climate Accord.

Japan, the former Soviet Union, (CIS), Canada and Australia, (JP CIS CA AU):  population ~356m, ~12.1% of global CO2 emissions.

These are nominally developed nations with some ambivalence towards controls on CO2 emissions and not necessarily adhering to the Paris Climate Accord.

Europe including the UK, Turkey and the Ukraine:  population ~650m, ~11.2% of global CO2 emissions.

This reassessment including Turkey and the Ukraine adds ~120 million to the wider European population with a resulting lowering of the overall CO2 emissions/head.  Currently European governments are still largely committed to action to combat Global Warming;  they have generally been enthusiastic supporters of the Paris Climate Accord, but the context is changing rapidly, including:

  • since February 2022 the war in Ukraine has suddenly made Western nations realise that their immediate energy security in the is much more important than any Green agenda to save the World from possible warming by the end of the century and that their Energy Security and injudicious dependence of Russian energy sources has enabled that Energy Security as a weapon against their economies.  But, after 30 years of unrelenting Green propaganda the Green agenda is still well established in the thinking of European Governments.
  • European peoples will come to understand the substantial changes to their lifestyles, personal economies and freedoms that are demanded by their governments’ to pursue the Net Zero / Green agenda and voters may be losing enthusiasm as they understand the real life implications of the imposed policies.
  • long-term policies providing generous subsidy support for “Renewables” as opposed to Conventional power generation have been pursued, particularly in Germany and the UK.
  • the preferential support of “Renewable” technologies has fruitlessly undermined investment in conventional reliable power generation to the extent that there is now real doubt about the ability of European power grids to provide a consistent service 24/7.
  • the subsidy support has meant that ~ 25% is aded to electricity bills go to support the “Renewable” technologies in the UK and elsewhere.  With escalating power bills European are at last realising that much of their increased costs are for the support of “Renewables” and progressively these expenditures will meet increasing resistance as the level of waste and the unreliability they represent becomes appreciated.
  • the Yellow Vests reaction in France was an immediate and violent reaction to the increase of fuel taxes on grounds of combatting climate change.  The fuel price rises in 2022 are much more drastic than those that induced the “Yellow Vest” reaction.
  • policies based on climate concerns are irrelevant to improving well-being in the Developing World, which has no interest for actions that would restrain their continuing development and well-being using their indigenous fossil fuels.

German Physicist: Human CO2 Emissions Responsible For 0.05°C Of The Global Warming Since 1750

by H. Harde, June 20,2022 in NoTricksZone

Professor Herman Harde, an environmental physicist, has authored a new position paper on the follies of assuming humans significantly impact the climate.

As detailed in his 2017 paper, Dr. Harde concludes the “anthropogenic contribution to the actual CO2 concentration is found to be 4.3% [a figure derived from IPCC AR5], its fraction to the CO2 increase over the Industrial Era is 15% and the average residence time 4 years.”

The IPCC overestimates the thermal effect of doubling CO2 by a factor of 5, as the consequent surface air temperature increase for a 120 ppm increase in CO2 is less than 0.3°C.

“Since only about 15% of the global CO2 increase is of anthropogenic origin, just 15% of 0.3°C, i.e., less than 0.05°C remains, which can be attributed to humans in the overall balance.”

“Changes of our climate can be traced back to natural interaction processes that exceed our human influence by orders of magnitude.”

Correcting Misinformation on Atmospheric Carbon Dioxide

by Bud Bromley, May 20, 2022 in budbromley

Abstract

Digital signal processing technology was used to analyze daily carbon dioxide data from the joint NOAA – Scripps Oceanographic Institution’s Global Monitoring Laboratory (MLO).  The period surrounding the 1991 eruption of the Pinatubo volcano was rigorously analyzed for slope and acceleration of net global average atmospheric CO2 concentration and found to be consistent with the theory that Henry’s Law, the Law of Mass Action, and Le Chatelier’s principle control net global average atmospheric CO2 concentration rather than human-produced CO2 emissions.  Background and theory are explained.  A method of using common physics and math for a novel purpose is presented to compare natural CO2emission or absorption with human-produced CO2 emission.  The claim that human-produced CO2 emission is causing increasing global CO2 concentration and climate change is shown to be without scientific merit.

Why is the CO₂ Concentration Rising?

by F. Schrijver, Apr 15, 2022 in WUWT

The general view in society is that human emissions of CO₂ are the all-determining cause of the increased concentration in the atmosphere. Most scientists and even many climate skeptics do not question this. There is some debate about how long this extra CO₂ will stay in the atmosphere, but that’s about it. That’s remarkable, as several scientists have published extensively on the flaws and inconsistencies of this narrative. By looking at the significant increase in the CO₂-flows from and to land and sea it’s in fact easy to see that the CO₂-rise is largely due to natural causes.

The idea that human CO₂ is the all-determining cause of the increased concentration is based on the assumption that the natural inflows and outflows are always and exactly in equilibrium with each other. Based on this perfect equilibrium thinking, human emissions, even though they are relatively small, cause a perturbation year after year. In the so-called global carbon budget[2] about 10 PgC of CO₂ is added every year, while the absorption flux has only increased by 6 PgC/yr (1 Petagram = 1 Gigaton = 1 billion tons). The concentration therefore continues to rise indefinitely as long as people emit CO₂.

To support this idea it is also assumed that human emissions accumulate in the atmosphere. Where you would expect a single residence time for a reservoir with in- and outflows, the IPCC-models calculate with a small residence time of about 4 years for natural CO₂ and a large one for human CO₂: “The removal of all the human-emitted CO2 from the atmosphere by natural processes will take a few hundred thousand years (high confidence)”.

Several scientists, including Murray Salby[9] and Hermann Harde[3], have published extensively on the flaws and inconsistencies of this narrative. They also showed that it is very illogical to think that a slight increase in the up-flux cannot be compensated by a larger down-flux. It’s like increasing the heat energy flow in a house by 5% and expecting that the temperature will keep on rising forever.

Despite this, belief in the IPCC’s model for the increase in concentration is persistent. In this article we will focus on one of the strangest assumptions: the idea that the in- and outflows are stable and in perfect equilibrium. Although they are about 20 times larger than anthropogenic fluxes and have different drivers for up and down, natural flows are not included in the material balance used in the models.

It is in fact easy to see that the increase in the CO₂ concentration is for the most part the result of natural changes, based on the following unmistakable observations.

  1. Fluxes to and from land and sea have increased significantly since 1750.

  2. The increase in these fluxes is natural, i.e. not due to human emissions.

  3. The growth of the natural fluxes can only take place at a higher concentration in the atmosphere.

CO2 Emissions Hit Record High in 2021

by P. Homewood, Mar 9, 2022 in NotaLotofPeopleKnowThat

Energy-related CO2 emissions grew to
36.3 Gt in 2021, a record high

 

Global CO2 emissions from energy combustion and industrial processes1 rebounded in 2021 to reach their highest ever annual level. A 6% increase from 2020 pushed emissions to 36.3 gigatonnes (Gt), an estimate based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy, economic and weather data.

The Covid-19 pandemic had far-reaching impacts on energy demand in 2020, reducing global CO2emissions by 5.2%. However, the world has experienced an extremely rapid economic recovery since then, driven by unprecedented fiscal and monetary stimulus and a fast – although uneven – roll-out of vaccines. The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions, which led to more coal being burnt despite renewable power generation registering its largest ever annual growth. 

Emissions increased by almost 2.1 Gt from 2020 levels. This puts 2021 above 2010 as the largest ever year-on-year increase in energy-related CO2 emissions in absolute terms. The rebound in 2021 more than reversed the pandemic-induced decline in emissions of 1.9 Gt experienced in 2020. CO2 emissions in 2021 rose to around 180 megatonnes (Mt) above the pre-pandemic level of 2019.

The 6% increase in CO2 emissions in 2021 was in line with the jump in global economic output of 5.9%. This marks the strongest coupling of CO2 emissions with Gross domestic product (GDP) growth since 2010, when global emissions rebounded by 6.1% while economic output grew by 5.1% as the world emerged from the Global Financial Crisis.

Global Human CO2 Emissions Have Been On A Slightly Declining Trend Since 2011

by K. Richard, Dec 9, 2021 in NoTricksZone

Until recently, human CO2 emissions were responsible for ~10% of the variance in year-to-year CO2 growth rate. But a new analysis says human CO2 emissions have been slightly declining for the last decade. So 0% responsible, apparently.

CO2 emissions derived from human activity (fossil fuel combustion and land use changes) only account for about +0.1 to 0.3 PgC/yr of the annual change in CO2 concentration. This is about “10% of the variance (σ²) of the CO2 growth rate” (Wang et al., 2013).

Emission Reductions From Pandemic Had Unexpected Effects on Atmosphere

by J. Lee & J. O’Neill, Nov 9, 2021 in JetPropulsionLaboratory

Earth’s atmosphere reacted in surprising ways to the lowering of emissions during the pandemic, showing how closely climate warming and air pollution are linked.

The COVID-19 pandemic and resulting limitations on travel and other economic sectors by countries around the globe drastically decreased air pollution and greenhouse gas emissions within just a few weeks. That sudden change gave scientists an unprecedented view of results that would take regulations years to achieve.

A comprehensive new survey of the effects of the pandemic on the atmosphere, using satellite data from NASA and other international space agencies, reveals some unexpected findings. The study also offers insights into addressing the dual threats of climate warming and air pollution. “We’re past the point where we can think of these as two separate problems,” said Joshua Laughner, lead author of the new study and a postdoctoral fellow at Caltech in Pasadena, California. “To understand what is driving changes to the atmosphere, we must consider how air quality and climate influence each other.”

Published Nov. 9 in the Proceedings of the National Academy of Sciences, the paper grew from a workshop sponsored by Caltech’s W.M. Keck Institute for Space Studies, led by scientists at that institution and at the Jet Propulsion Laboratory in Southern California, which is managed by Caltech. Participants from about 20 U.S. and international universities, federal and state agencies, and laboratories pinpointed four atmospheric components for in-depth study: the two most important greenhouse gases, carbon dioxide and methane; and two air pollutants, nitrogen oxides and microscopic nitrate particles.

Carbon Dioxide

The most surprising result, the authors noted, is that while carbon dioxide (CO2) emissions fell by 5.4% in 2020, the amount of CO2 in the atmosphere continued to grow at about the same rate as in preceding years. “During previous socioeconomic disruptions, like the 1973 oil shortage, you could immediately see a change in the growth rate of CO2,” said David Schimel, head of JPL’s carbon group and a co-author of the study. “We all expected to see it this time, too.”

Using data from NASA’s Orbiting Carbon Observatory-2 satellite launched in 2014 and the NASA Goddard Earth Observing System atmospheric model, the researchers identified several reasons for this result. First, while the 5.4% drop in emissions was significant, the growth in atmospheric concentrations was within the normal range of year-to-year variation caused by natural processes. Also, the ocean didn’t absorb as much CO2 from the atmosphere as it has in recent years – probably in an unexpectedly rapid response to the reduced pressure of CO2 in the air at the ocean’s surface.

BBC’s Fake GHGs Graph

by P. Homewood, Nov 15, 2021 in NotaLot ofPeopleKnowThat

For the last few weeks, the BBC has been regularly publishing the above graph from Climate Action Tracker, showing the extra emission reductions resulting from the new NDCs, National Plans, submitted for COP26.

Essentially they estimate a figure of 3.3 to 4.7 GtCO2e for all GHGs. Significantly this means that they will still be much higher than 2010 in 2030. According to the science, they need to be cut by 45% from 2010 levels to stay on track for 1.5C

Curiously however in the last few days, the BBC has dropped the above graph, and replaced with an ostensibly fake one, which claims that the new COP26 pledges will cut emissions by 10.5 GtCO2e, more than double the Climate Tracker numbers, bringing 2030 levels down to 90% of 2010 ones.

Does Scientific Data Show Humans, CO2, And Fossil Fuels Cause Global Warming?

by J. Heller, Aug 10, 2021 in ClimateChangeDispatch

Another day, another dire warning about global warming.

The press and its taskmasters could essentially Xerox a copy of what they printed for the public in the Washington Post in 1922, or a UN report in 1989, or a UN report in 2019 for this report here:

U.N. climate report likely to deliver stark warnings on global warming

As always, journalists just print and repeat these never-ending reports to scare the public into submission with no questions asked.

For decades, journalists, educators, scientists, bureaucrats, and other Democrats have colluded to spread these dire warnings, (misinformation) without scientific evidence, to scare and control the public.

We are repeatedly have been told that we only have a few years left to solve the problem.

The end date always evolves. No matter how wrong these dire predictions are they just repeat them and say the science is settled to cut off debate. Why are people who are always so wrong considered experts?

Many CEOs, Republicans, and others repeat the same claims without evidence because it is so much more pleasant to go along instead of being called anti-science, or worse still, “deniers.”

In D.C., and throughout the country, politicians are using these dire forecasts to pass policies to destroy thousands of industries and millions of jobs.

Joe Biden and his administration have been in office for seven months and are working as fast as they can to remake and destroy America.

He has signed executive orders to stop a pipeline, stop drilling and force people to buy vehicles powered by the poisonous, very combustible pollutant Lithium. These anti-oil policies greatly harm the poor, middle class, and small businesses with higher prices.

The Biden administration has rejoined the Paris climate accord where politicians and bureaucrats from around the world pretend they can control temperatures, sea levels, and storm activity if thousands of industries are destroyed and we hand them trillions of our hard-earned dollars.

Does anyone really believe that Iran, Russia, and other major oil-producing countries will give up oil? Isn’t it important that Biden let a pipeline proceed from Russia to Germany while stopping the pipeline from Canada to the United States?

Does anyone believe that China cares about its carbon footprint as it continues to build a large number of coal power plants? Here’s what’s going on in China:

Despite Pledges to Cut Emissions, China Goes on a Coal Spree

As the Biden administration works so hard to destroy industries, I have not seen one journalist as Biden, Harris, Kerry, Psaki, or anyone else in the administration who has been asked for evidence to support the claimed science that can justify what Biden is doing.

In a free society with independent journalists, we should see the reporters asking questions and doing research to see if what they are told is correct before they repeat talking points to the public.

Sadly, in the United States, we have seen, for decades, almost all journalists have essentially become campaign workers to elect Democrats and lobbyists to sell the radical leftist policies to the public.

Media outlets, especially the social media giants, work very hard to stifle debate and silence anyone who disagrees by repeating the talking points that we are anti-science and climate change deniers who should not be listened to.

It is an outright lie to call people who tell the truth that the climate has always changed cyclically and natural climate-change deniers. I have never seen anyone deny that the climate changes.

China, India And 85 Nations Snub U.N. Deadline To Update CO2-Reduction Targets

by Dr. B. Peiser, Aug  2, 2021 in GWPF/ClimateChangeDispatch

In a warning shot across the bows of Joe Biden and Boris Johnson, China, India, and 85 other nations have decided to ignore a UN deadline to submit its pledges for cutting CO2 emissions in time for the UN climate summit in Glasgow later this year.

To underscore their opposition to Joe Biden’s and Boris Johnson’s Net Zero agenda, India has snubbed the UK’s climate meeting last week while China is rolling back its climate policies in an attempt to prop up its economy.

Meanwhile, South Africa has demanded that developed countries should set a target of $750 billion a year to help poorer nations transition to renewable energy.

The latest demands and developments look increasingly like a farcical repeat of the fiasco of the Copenhagen climate summit (COP15) in 2009.

As seasoned COP observers remember, after two weeks of deadlocked negotiations in Denmark’s capital, the leaders of Brazil, Russia, India, China, and South Africa (the so-called BRICS nations) took charge of the climate summit which was on the brink of disaster and drafted the final communique behind closed doors.

A humiliated US President Obama had to gatecrash the meeting while the entire EU was excluded from the meeting and the final statement.

In many ways, Copenhagen’s diplomatic and political fiasco was a historical watershed that marked the turning point when 500 years of Western dominance was symbolically terminated by China and India.

If Boris and Biden are not very careful, they may face a very similar situation in Glasgow. If push comes to shove there is a pretty good chance that China and India (together with a number of emerging nations) could take over a deadlocked COP yet again and draft an agreement that suits them and humiliates the US, UK, and the EU.

There is, of course, one shrewd game plan to avoid a Copenhagen-type fiasco: Boris Johnson could simply pull the plug on current summit plans, turn COP26 into a virtual conference, and blame Covid for the failure to achieve a breakthrough.

After all, Boris has developed a habit of kicking irreconcilable issues into the long grass … just saying.

Just 25 ‘mega-cities’ produce 52 per cent of the world’s urban greenhouse gas emissions — and 23 of them are in China

by I. Randall, July 12, 2021 in DailyMail

  • Researchers from Sun Yat-sen University recorded the emissions of 167 cities

  • The largest carbon emitters were found to be Asian megacities like Shanghai

  • Cities in Europe and the US emit more than those in most developing countries

EIA: U.S. CO2 Emissions Dropped 11% In 2020; No Change In Rising Atmospheric CO2

by A. Watts, Apr 16, 2021 in ClimateChangeDispatch

Climate change action proponents regularly tell us we have to reduce our carbon dioxide (CO2) emissions to prevent “climate change”, even to the point of curtailing industry, travel, and food consumption.

Fortunately, a real-world test of just those very things happened in 2020 due to the COVID-19 related lockdowns.

In a report released April 12th by the U.S. Energy Information Administration (EIA) the Monthly Energy Review, they report that energy-related CO2 emissions decreased by 11% in the United States in 2020 primarily because of the effects of the COVID-19 pandemic and related restrictions.

Furthermore, U.S. energy-related CO2 emissions fell in every end-use (consumer) sector for the first time since 2012. The EIA notes:

“CO2 emissions associated with energy use fell by 12% in the commercial sector in 2020. Part of this drop in emissions was due to pandemic restrictions.

“Because electricity is a large source of energy for the commercial sector, the declining carbon intensity of electric power also contributed to declining CO2 emissions from commercial activity. Emissions from commercial electricity use fell by 13%. Commercial petroleum and natural gas emissions fell by 13% and 11%, respectively.

“Within the U.S. power sector, emissions from coal declined the most, by almost a fifth, at 19%. Natural gas-related CO2 emissions rose by 3%. Also of note in 2020; fossil fuel generation declined, while power generation from renewables from wind and solar continued to grow.”

EIA: U.S. CO2 Emissions Declined 11% in 2020 – No Change in Rising Atmospheric Carbon Dioxide

As seen in the graph above, CO2 in the atmosphere increased during 2020 during the economy crippling lockdowns at the same rate it has been for decades. There isn’t even a blip.

This lack of any reduction in atmospheric CO2 concentration clearly demonstrates that no matter how much the U.S. reduces CO2 emissions, no one living today will, at any point in life, see a measurable change in climate attributable to the reduction. This is especially true since other countries, such as China, who only give lip-service to the CO2 emissions reduction demanded by the 2015 Paris Climate Accord.

Shock News–China 5-Year Plan Will Increase Emissions

by P. Homewood, March 6, 2021 in NotaLotofPeopleKnowThat

China has set out an economic blueprint for the next five years that could lead to a strong rise in greenhouse gas emissions if further action is not taken to meet the country’s long-term goals.

The 14th five-year plan, published in Beijing on Friday, gave few details on how the world’s biggest emitter would meet its target of reaching net zero emissions by 2060, set out by President Xi Jinping last year, and of ensuring that carbon dioxide output peaks before 2030.

China will reduce its “emissions intensity” – the amount of CO2 produced per unit of GDP – by 18% over the period 2021 to 2025, but this target is in line with previous trends, and could lead to emissions continuing to increase by 1% a year or more. Non-fossil fuel energy is targeted to make up 20% of China’s energy mix, leaving plenty of room for further expansion of the country’s coal industry.

Swithin Lui, of the Climate Action Tracker and NewClimate Institute, said: “[This is] underwhelming and shows little sign of a concerted switch away from a future coal lock-in. There is little sign of the change needed [to meet net zero].”

Zhang Shuwei, chief economist at Draworld Environment Research Centre, said: “As the first five-year plan after China committed to reach carbon neutrality by 2060, the 14th five-year plan was expected to demonstrate strong climate ambition. However, the draft plan presented does not seem to meet the expectations. The international community expected China’s climate policy to ‘jump’, but in reality it is still crawling.”

Unusually, this five-year plan did not set out GDP targets for the whole five-year period, but allowed for annual targets, with the first for this year a target of 6% growth. The Centre for Research on Energy and Clean Air said that coupled with the emissions intensity target, this could allow the growth rate of China’s emissions to speed up even further, rather than slow down, as is needed.

2020 Review: Observational And Modeling Studies Show Temperature Falls As CO2 Rises

by K. Richard, Dec 28, 2020 in NoTricksZone

A 2020 observational study (Zhang et al., 2020) determined “temperatures of atmospheric air with substantially higher CO2 concentration (ranging from 3200 ppm to 16,900 ppm) were lower than that with the lower CO2 concentration (480 ppm)” and a 2020 modeling study (Drotos et al., 2020) assessed that when CO2 goes beyond 4 times preindustrial – 1,120 ppm – “climate sensitivity decreases to nearly zero” because the climate cyclically cools by 10 K.

So the science is settled, right?
