THE UN ADMITS THAT THE PARIS CLIMATE DEAL WAS A FRAUD

by Poppallov, February 24, 2020 in Electroverse


In an editorial piece published in the Investor’s Business Daily Saturday 11th February 2017, we are told about a United Nations climate report that environmentalists undoubtedly don’t want anybody to read. It states in plain English “that even if every country abides by the grand promises they made last year in Paris to reduce greenhouse gases, the planet would still be doomed…”

When President Obama hitched America to the Paris accords in 2016, he declared that it was “the moment that we finally decided to save our planet.” And when Trump pulled out of the deal this year, he was berated by legions of environmentalists for killing it.

But it turns out that the Paris accord was little more than a sham that will do nothing to “save the planet.”

According to the latest annual UN report on the “emissions gap,” the Paris agreement will provide only a third of the cuts in greenhouse gas that environmentalists claim is needed to prevent catastrophic warming. If every country involved in those accords abides by their pledges between now and 2030 — which is a dubious proposition — temperatures will still rise by 3 degrees Celsius by 2100. The goal of the Paris agreement was to keep the global temperature increase to under 2 degrees.

The measures submitted included: “Boosting renewable energy’s share to 30%. Pushing electric cars to 15% of new car sales, up from less than 1% today. Doubling mass transit use. Cutting air travel CO2 emissions by 20%. And coming up with $1 trillion for “climate action.”

Central to the report, “phasing out coal consumption … is an indispensable condition for achieving international climate change targets.” That means halting all new coal plants shutting down those currently in use.

Which is quite a big ask, as there are currently 273 gigawatts of coal capacity under construction around the world, and another 570 gigawatts in the pipeline, according to the UN. That’s a 42% increase in global energy production from coal. Which doesn’t consider the 22 coal-fired power stations to be built at 17 locations in Japan to replace their aging nuclear plants. These new installations will on their own produce more carbon dioxide annually than all the passenger cars sold in the United States each year.

So, with all the hype in the media about “climate change” and with NOAA admitting to data manipulation, as well as acknowledging that the climate has been cooling for the past 10 years, when is the UN going to shut-up shop and call an end to this panhandling charade?

Expert: German Coal Exit Will Cost 80 Billion Euros, But “Changes Europe CO2 Emissions By 0”

by P. Gosselin, February 22, 2020 in NoTricksZone


The German government recently decided to exit from coal generated power by 2038, and now one expert says that the exit is going to cost handsomely, and bring zero result. Still, that 2038 target is too slow for some.

That’s how German politicians make decisions on things that concern the economy and environment. The German government’s aim of a coal phaseout is to contribute to protecting the climate. In reality, it will have no impact at all.

German online FOCUS magazine reports here: “80 billion euros are to be given to the affected regions and companies in the coming years as aid and compensation.”

But for some experts, the 2018 target date for completing the coal exit is too late, and thus risks seeing Germany emitting another 140 million tonnes of extra CO2 between 2020 and 2040 by exiting so slowly, so claims the German Institute for Economic Research (DIW).

To keep that 140 million ton figure in a global perspective, it is barely a drop in the bucket when compared to the 33 billion tonnes emitted globally and annually. The climate is not even going to notice it.

Quantifying Futility: an estimate of future Global CO2 emissions

by C. Rotter, February 21, 2020 in WUWT


Reposted from edmhdotme

Following the thinking of the late Prof David Mackay using “back of the envelope calculations”, this post makes estimates of the likely future growth in global CO2 emissions to put the efforts at CO2 emissions reduction in the Western World into the context of a probable and inevitable future for Global CO2 emissions.

Two scenarios are considered.  They set the range of outcomes:

  1. The Underdeveloped world and India presently at a level of ~1.9tonnes/head/annum attain the global average level of CO2 emissions/head/annum of 2018:  4.46tonnes/head/annum.  This results in Global CO2 emissions growing by 18.5Gigatonnes/annum to reach ~52Gigatonnes/annum.  This level is close to the current CO2 emissions/head/annum in France.
  2. The Underdeveloped world and India eventually attain the level of CO2 emissions/head current in China:  6.78tonnes/head/annum.  This level is also close to the average 2018 CO2 emissions/head/annum in the EU(28). This would result in Global CO2 emissions growing by ~33.5Gigatonnes/annum to reach ~67Gigatonnes/annum.

These values set a range of estimates and show how the inevitable CO2 emissions growth in the Developing World would swamp any savings made by Western nations in the name of controlling climate.  This point was amply made by Berkley Professor Richard  Muller in 2010, before he set up the BEST temperature record.  His graph is shown below:  this post just puts some more precise values on the extent that the Underdeveloped world will wholly overwhelm any efforts in the West to reduce Global  CO2 emissions and thus attempt to influence Global temperature.

Physics Professor: CO2’s 0.5°C Impact After Rising To 700 ppm Is So Negligible It’s ‘Effectively Unmeasurable’

by P. Stallinga, February 13, 2020 in NoTricksZone


Dr. Peter Stallinga has published a comprehensive analysis of the Earth’s greenhouse effect. He finds an inconsequential role for CO2.

Doubling CO2 from 350 to 700 ppm yields a warming of less than 0.5°C (500 mK).

Feedbacks to warming are likely negative, as adding CO2 may only serve to speed up natural return-to-equilibrium processes.

As for absorption-reemission perturbation from CO2, “there is nothing CO2 would add to the current heat balance in the atmosphere.”

A portion of Dr. Stallinga’s paper worth highlighting – which he mentions only in passing – refers to the early history of the Earth’s greenhouse effect paradigm.

K. Ångström receives little attention as a pioneer of the conceptualization that warming and cooling resul from radiative imbalances within a planetary greenhouse effect.

About 120 years ago, Ångström (1900) contradicted the oft-cited Arrhenius (1896) – the atmospheric physicist referred to by proponents of anthropogenic global warming.

Ångström suggested Earth’s greenhouse effect is already saturated in its current (1900) state, and therefore increasing CO2 will have “no effect whatsoever” on climate (Stallinga, 2020).

Ångström’s conclusions were largely ignored.

Bad news for climate alarmists: global carbon dioxide emissions flatlined in 2019

by A. Watts, February 13, 2020 in WUWT


From the inconvenient data department and the IEA comes this press release.


Despite widespread expectations of another increase, global energy-related carbon dioxide emissions stopped growing in 2019, according to IEA data released today.

After two years of growth, global emissions were unchanged at 33 gigatonnes in 2019 even as the world economy expanded by 2.9%. This was primarily due to declining emissions from electricity generation in advanced economies, thanks to the expanding role of renewable sources (mainly wind and solar), fuel switching from coal to natural gas, and higher nuclear power generation. Other factors included milder weather in several countries, and slower economic growth in some emerging markets.

Global Fossil Fuel Emissions Up 0.6% In 2019

by P. Homewood, February 6, 2020 in NotaLotofPeopleKnowThat


Emissions from fossil fuel and industry (FF&I) are expected to reach 36.81bn tonnes of CO2 (GtCO2) in 2019, up by only 0.24GtCO2 (0.6%) from 2018 levels, according to the latest estimates from the Global Carbon Project (GCP).

The data is being published in Earth System Science Data Discussions, Environmental Research Letters and Nature Climate Change to coincide with the UN’s COP25 climate summit in Madrid, Spain.

The growth of global emissions in 2019 was almost entirely due to China, which increased its CO2 output by 0.26GtCO2. The rest of the world actually reduced its emissions by -0.02GtCO2, thanks to falling coal use in the US and Europe, as well as much more modest increases in India and the rest of the world, compared to previous years.

The GCP researchers say that “a further rise in emissions in 2020 is likely” as global consumption of natural gas is “surging”, oil use continues to increase and, overall, energy demand rises.

Despite the rapid rise and falling costs of renewables in many parts of the world, the majority of increases in energy demand continue to be met by fossil fuels. For example, gas met around two-fifths of the increase in demand in 2018, against just a quarter coming from renewables.

Overall, human-caused CO2 emissions, including those from FF&I and land use, are projected to increase by 1.3% in 2019. This is driven by a 0.29GtCO2 (5%) increase in land-use emissions – including deforestation –  which is the fastest rate in five years. While land use only represents around 14% of total 2019 emissions, it will contribute more than half the increase in emissions in 2019.

While more modest than in recent years, the increase in emissions in 2019 puts the world even further away from meeting its climate change goals under the Paris Agreement.

Will Humanity Ever Reach 2XCO2? Possibly Not

by Dr. Roy Spencer, February 2, 2020 in WUWT


Summary

The Energy Information Agency (EIA) projects a growth in energy-based CO2 emissions of +0.6%/yr through 2050. But translating future emissions into atmospheric CO2 concentration requires a global carbon budget model, and we frequently accept the United Nations reliance on such models to tell us how much CO2 will be in the atmosphere for any given CO2 emissions scenario. Using a simple time-dependent CO2 budget model forced with yearly estimates of anthropogenic CO2 emissions and optimized to match Mauna Loa observations, I show that the EIA emissions projections translate into surprisingly low CO2 concentrations by 2050. In fact, assuming constant CO2 emissions after 2050, the atmospheric CO2 content eventually stabilizes at just under 2XCO2.

Introduction

I have always assumed that we are on track for a doubling of atmospheric CO2 (“2XCO2”), if not 3XCO2 or 4XCO2. After all, humanity’s CO2 emissions continue to increase, and even if they stop increasing, won’t atmospheric CO2 continue to rise?

It turns out, the answer is probably “no”.

The rate at which nature removes CO2 from the atmosphere, and what controls that rate, makes all the difference.

Even if we knew exactly what humanity’s future CO2 emissions were going to be, how much Mother Nature takes out of the atmosphere is seldom discussed or questioned. This is the domain of global carbon cycle models which we seldom hear about. We hear about the improbability of the RCP8.5 concentration scenario (which has gone from “business-as-usual”, to “worst case”, to “impossible”), but not much about how those CO2 concentrations were arrived at from CO2 emissions data.

So, I wanted to address the question, What is the best estimate of atmospheric CO2 concentrations through the end of this century, based upon the latest estimates of future CO2 emissions, and taking into account how much nature has been removing from the atmosphere?

As we produce more and more CO2, the amount of CO2 removed by various biological and geophysical processes also goes up. The history of best estimates of yearly anthropogenic CO2 emissions, combined with the observed rise of atmospheric CO2 at Mauna Loa, Hawaii, tells us a lot about how fast nature adjusts to more CO2.

Analysis of a carbon forecast gone wrong: the case of the IPCC FAR

by J. Curry, January 31, 2020 in WUWT-C. Rotter


The IPCC’s First Assessment Report (FAR) made forecasts or projections of future concentrations of carbon dioxide that turned out to be too high.

From 1990 to 2018, the increase in atmospheric CO2 concentrations was about 25% higher in FAR’s Business-as-usual forecast than in reality. More generally, FAR’s Business-as-usual scenario expected much more forcing from greenhouse gases than has actually occurred, because its forecast for the concentration of said gases was too high; this was a problem not only for CO2, but also for methane and for gases regulated by the Montreal Protocol. This was a key reason FAR’s projections of atmospheric warming and sea level rise likewise have been above observations.

Some researchers and commentators have argued that this means FAR’s mistaken projections of atmospheric warming and sea level rise do not stem from errors in physical science and climate modelling. After all, emissions are for climate models an input, not an output. Emissions depend largely on economic growth, and can also be affected by population growth, intentional emission reductions (such as those implemented by the aforementioned Montreal Protocol), and other factors that lie outside the field of physical science. Under this line of reasoning, it makes no sense to blame the IPCC for failing to predict the right amount of atmospheric warming and sea level rise, because that would be the same as blaming it for failing to predict emissions.

Readers who have made it to this part of the article probably want a summary, so here it goes:

  • Hausfather estimates that FAR’s Business-as-usual scenario over-projected forcings for the 1990-2017 period by 55%. This would mean a difference of 0.59 w/m2 between FAR and reality.
  • Lower-than-expected concentrations of Montreal Protocol gases explain about 0.19 w/m2 of the difference. With the big caveat that Montreal Protocol accounting is a mess of CFCs, HCFCs, HFCs, stratospheric ozone, and perhaps other things I’m not even aware of.
  • FAR didn’t account for tropospheric ozone, and this ‘unexplains’ about 0.07 w/m2. So there’s still 0.45-0.5 w/m2 of forcing overshoot coming from something else, if Hausfather’s numbers are correct.
  • N2O is irrelevant in these numbers
  • CO2 concentration was significantly over-forecasted by the IPCC, and that of methane grossly so. It’s safe to assume that methane and CO2 account for most or all of the remaining difference between FAR’s projections and reality.

Again, this is a rough calculation. As mentioned before, an exact calculation has to take into account for many issues I didn’t consider here. I really hope Hausfather’s paper is the beginning of a trend in properly evaluating climate models of the past, and that means properly accounting for (and documenting) how expected forcings and actual forcings differed.

China Burns Over Half Of The World’s Coal And Will Account For 50% Of Global CO2 Emissions By 2030

by K. Richard, December 19, 2019 in NoTricksZone


Today, 30% of the globe’s CO2 emissions come from China. In 10 years, China’s emissions alone will match the rest of world’s emissions combined. China continues to build hundreds of coal plants today. So why are the rest of us spending $600 billion every year on CO2 emissions mitigation?

China overtook the United States as the world’s largest CO2 emitter in 2008 (Liu et al., 2019).

Paris Won’t Cut Emissions–Bob Watson

by P. Homewood, November 10, 2019 in NotaLotofPeople KnowThat


It’s apparently taken ex IPCC Chair Bob Watson four years to work out that the Paris Agreement did nothing to reduce emissions.

It’s a pity he did not read this blog, because I was saying the same thing when it was signed!

Steve Milloy reports:

 

The truth behind the Paris Agreement climate pledges

Almost 75% of 184 Paris Agreement pledges were judged insufficient to slow climate change; Only 28 European Union nations and 7 others will reduce emissions by at least 40% by 2030

UNIVERSAL ECOLOGICAL FUND

  • Only 28 European Union nations & 7 others will reduce emissions by at least 40 percent by 2030
  • China & India, top emitters, will reduce emissions intensity, but their emissions will increase
  • U.S., second top emitter, has reversed key national policies to combat climate change
  • Almost 70 percent of the pledges rely on funding from wealthy nations for their implementation

Almost three-quarters of the 184 climate pledges made under the Paris Agreement aimed at curbing greenhouse gas emissions are inadequate to slow climate change, and some of the world’s largest emitters will continue to increase emissions, according to a panel of world-class climate scientists. It is these increasing greenhouse emissions that are driving climate change.

The Truth Behind the Climate Pledges, a new report published by the Universal Ecological Fund, examines in great detail the 184 voluntary pledges under the Paris Agreement, the first collective global effort to address climate change.

Paris Climate Accord — A Blank Check For CO2 Emissions By China And India

by Dr. Benny Peiser, Nov. 5, 2019 in ClimateChangeDispatch


The Paris Climate Agreement, far from securing a reduction in global CO2 emissions, is fundamentally a blank cheque that allows China and India to increase their emissions as they see fit in pursuit of economic growth.

This is the conclusion of a new paper by Law Professor David Campbell (Lancaster University Law School) and published today by the Global Warming Policy Foundation.

For the last 25 years, international climate change law has failed to agree on a program of global emissions reductions.

Indeed this law grants permission to major emitters such as China and India to emit as much as they see fit. Global emissions reductions, therefore, have always been impossible and since 1992 global emissions have enormously increased.

Indeed, the Paris Agreement contains a categorical statement that countries such as China and India will not be obliged to undertake any reductions.

The UK Government proposes to continue with decarbonization even though Britain’s unilateral decarbonization is utterly pointless and thus wholly irrational.

Russia Scraps Plans to Set Climate-Change Goals for Businesses

by Natasha Doff, November 7, 2019 in Bloomberg


Bloomberg) — Russia has ditched plans to set greenhouse-gas emissions targets for companies as a sign of its commitment to fighting climate change, following lobbying from big businesses that risked fines if they didn’t comply.

The measure was part of a bill intended to accompany Russia’s ratification of the 2015 Paris Agreement on climate change in September. Instead, the world’s fourth-largest carbon polluter scrapped the proposal after the Russian Union of Industrialists and Entrepreneurs (RSPP) warned it would raise costs for companies and delay investment.

“After consultations with the government, it was decided to abandon the specific regulatory requirements,” the press department of the Economy Ministry, which is drafting the bill, said by email. “The government will have the right to decide after Jan. 1, 2024 what measures to introduce if Russia is forecast to miss its emissions targets.”

Solar activity drives CO2 levels

by R. Mac, August 10, 2014  in TheHockeySchtick


Hypothesis: Increasing accumulated solar activity [sunspot time-integral] since the Maunder Minimum 1645-1715 AD has warmed the oceans and land, warming of the oceans has increased ocean outgassing of CO2 [Henry’s Law] and has been the primary cause of increased atmospheric CO2 levels. Ocean temperatures driven by solar activity control atmospheric CO2 levels on short, intermediate, and long-term timescales.

Also note if increased solar activity warms the oceans, the solubility of CO2 in the oceans decreases due to Henry’s Law, thus preventing “acidification” of the oceans. If the oceans are warming due to any cause, Henry’s Law says solubility of CO2 decreases and outgassing increases, preventing “acidification” from man-made and natural sources of CO2. Warnings about ocean acidification are misleading and overblown:

Net-Zero Carbon Dioxide Emissions By 2050 Requires A New Nuclear Power Plant Every Day

by Roger Pielke, Sep. 30, 2019 in WUWT


I research and write about science, policy and politics.

More than a decade ago, Gwyn Prins and Steve Rayner characterized climate policy as an “auction of promises” in which politicians “vied to outbid each other with proposed emissions targets that were simply not achievable.” For instance, among Democrats competing for the presidency in 2020, several, including Joe Biden, have committed to achieving net-zero carbon dioxide emissions by 2050. Candidate Andrew Yang bid 2049, and Cory Booker topped that by offering 2045. Bernie Sanders has offered a 71% reduction by 2030.

One reason that we see this “auction of promises” is that the targets and timetables for emissions reductions are easy to state but difficult to comprehend. Here I’ll present what net-zero carbon dioxide emissions for 2050 actually means in terms of the rate of deployment of carbon-free energy and the coincident decommissioning of fossil fuel infrastructure.

To conduct this analysis I use the BP Statistical Review of World Energy, which presents data on global and national fossil fuel consumption in units called “million tons of oil equivalent” or mtoe. In 2018 the world consumed 11,743 mtoe in the form of coal, natural gas and petroleum. The combustion of these fossil fuels resulted in 33.7 billion tonnes of carbon dioxide emissions. In order for those emissions to reach net-zero, we will have to replace about 12,000 mtoe of energy consumption expected for 2019. (I ignore so-called negative emissions technologies, which do not presently exist at scale.)

Another useful number to know is that there are 11,051 days left until January 1, 2050. To achieve net-zero carbon dioxide emissions globally by 2050 thus requires the deployment of >1 mtoe of carbon-free energy consumption (~12,000 mtoe/11,051 days) every day, starting tomorrow and continuing for the next 30+ years. Achieving net-zero also requires the corresponding equivalent decommissioning of more than 1 mtoe of energy consumption from fossil fuels every single day.

Another important number to consider is the expected increase in energy consumption in coming decades. The International Energy Agency currently projects that global energy consumption will increase by about 1.25% per year to 2040. That rate of increase in energy consumption would mean that the world will require another ~5,800 mtoe of energy consumption by 2050, or about another 0.5 of an mtoe per day to 2050. That brings the total needed deployment level to achieve net-zero emissions to about 1.6 mtoe per day to 2050.

Global decarbonisation efforts ‘stall’, pushing climate goals out of reach

by Matt  Mace, Sep. 19, 2019 in Euractiv


Global decarbonisation efforts will need to be seven times greater if the world is to stand a fair chance of limiting global warming to 1.5C, according to a new PwC report which found decarbonisation has slowed to its lowest level since 2011. EURACTIV’s media partner edie.net reports.

PwC UK’s latest Low Carbon Economy Index (LCEI), published today (19 September), found that reaching the Paris Agreement’s 2C limit for global warming would require the global economy to reduce its carbon intensity by 7.5% every year up to 2100. The report notes that this is five times faster than the current decarbonisation rate of 1.6% – less than half the decarbonisation rate witnessed in 2015 (of 3.3%), when the Paris Agreement was introduced.

In order to meet the more ambitious target of the Paris Agreement – limiting global warming to 1.5C which has been requested by the Intergovernmental Panel on Climate Change (IPCC’s) special report – decarbonisation rates must reach 11.3% annually. That is seven times greater than the current rate, which has slowed to its lowest level since 2011.

FORGET PARIS: CHINA’S NEW COAL BOOM

by Reuters, August 6, 2019 in GWPF


SHANGHAI/BEIJING (Reuters) – Approvals for new coal mine construction in China have surged in 2019, government documents showed, with Beijing expecting consumption of the commodity to rise in the coming years even as it steps up its fight against smog and greenhouse gas emissions.

 

 

Long-term cuts in coal consumption are a key part of China’s energy, environment and climate goals, but the fivefold increase in new mine approvals in the first-half of 2019 suggests China’s targets still provide ample room for shorter-term growth.

China’s energy regulator gave the go-ahead to build 141 million tonnes of new annual coal production capacity from January to June, compared to 25 million tonnes over the whole of last year, Reuters analysis of approval documents showed.

The projects included new mines in the regions of Inner Mongolia, Xinjiang, Shanxi and Shaanxi that are part of a national strategy to consolidate output at dedicated coal production “bases”, as well as expansions of existing collieries, the National Energy Administration (NEA) documents showed. […] Chinese coal output rose 2.6% in the first-half of 2019 to 1.76 billion tonnes.

MORE TO COME?

Industry groups still expect coal-fired power capacity to increase over the next few years, with investments in nuclear and renewables still insufficient to cover rising energy demand.

The research unit of the China State Grid Corporation last month forecast that total coal-fired capacity would peak at 1,230-1,350 gigawatts (GW), which would mean an increase of about 200-300 GW.

A study published earlier this year also suggested China’s targets would allow the construction of another 290 GW of coal-fired capacity in the coming years.

Developing nations latest decade of energy & emissions growth torpedoes alarmist global emissions control scam

by Larry Hamlin, July 23, 2019 in WUWT


The UN has been pursuing global emissions policy for decades that are intended to provide for the establishment of global government schemes allowing it to control world emissions.

No fewer than 24 United Nations Climate Change Conferences have been held at various global locations since 1995 under its Conference of the Parties (COP) legal framework.

COP 21 which occurred in November and December 2015 in Paris resulted in the creation of the Paris Agreement that supposedly established global agreement to reduce greenhouse gas emissions and limit future global temperatures that the UN based upon projections from climate models that grossly exaggerate the impact of greenhouse gases on world temperatures.

The UN IPCC acknowledged in its AR3 climate report in 2001 that it is not possible to develop computer models that are capable of predicting future global climate and yet the Paris Agreement based its emissions targets intended for the future using these flawed computer models.

Three additional UN climate conferences have occurred since the Paris Agreement with the last conference being in 2018 in Poland. No success has been achieved in these three conferences in devising specific commitments for emissions reductions targets for the world’s developing nations.

Additionally the U.S. under President Trump wisely withdrew from the Paris Agreement in June of 2017.

Global energy and emissions detailed information for 2018 is now available which includes data encompassing the latest decade of 2008 to 2018. The world energy consumption data from the report is summarized in the graph below.

This latest decade energy and emissions data clearly demonstrates that the developing nations completely dominate global energy and emissions. This includes both present levels as well as future growth. These results also show that the developed nations play a minority role in these measures both presently and in the future.

The results for the last decade show that global energy use grew by 18.5% during the last decade with 98.5% of that energy growth accounted for by the developing nations.

Capture et stockage du CO2 : une situation étrange…

by Claude Mandril, 13 mai 2019 in ConnaissanceDesEnergies


La capture et le stockage de CO2 (CCS(1)) est indispensable…

Les accords de Paris ont donné l’objectif : un réchauffement climatique « well below 2°C » d’ici 2100 par rapport aux températures de l’ère préindustrielle.

Le dernier rapport du GIEC montre par ailleurs qu’on serait « beaucoup mieux » à + 1,5°C, et que tout dixième de degré compte : + 1,7°C vaut mieux que + 1,8°C. Il faut donc, ajoute le GIEC, atteindre la neutralité carbone autour de 2050.

Or il est complètement exclu d’arrêter toutes les émissions de gaz à effet de serre, et de loin ! :

  • l’AIE estime dans son scénario Sustainable Development (le plus contraignant)(2) que les énergies fossiles représenteront encore 60% de la fourniture mondiale d’énergie en 2040. Même si on juge l’AIE timorée, on est clairement hors limite ! ;

  • la capacité d’extraction charbonnière en Chine a augmenté de 6% en 2018 (selon la National Energy Administration en Chine) ;

  •  et surtout, n’oublions pas les émissions « de procédé » (ciment, sidérurgie, chimie, agroalimentaire).

Donc il faudra des « puits » de carbone. En premier lieu, les forêts mais à condition qu’elles soient exploitées et que les produits de cette exploitation donnent un stockage permanent. L’incendie de Notre-Dame de Paris montre que ce n’est pas garanti… L’usage du bois en chaudière réduit les émissions en remplaçant des émissions de carbone fossile, mais ce n’est pas un puits (sauf avec CCS !).

Reste donc la CCS, qui est indispensable. D’ailleurs, sur les 4 scénarios du GIEC, 3 comportent le déploiement de la CCS, le 4e étant un repoussoir.

Et pourtant la CCS est complètement ignorée voire vilipendée, sauf dans une dizaine de pays.

What Humans Contribute to Atmospheric CO2: Comparison of Carbon Cycle Models with Observations

by Herman Harde, April 3, 2019 in Earth Sciences


Abstract: The Intergovernmental Panel on Climate Change assumes that the inclining atmospheric CO2 concentration over

recent years was almost exclusively determined by anthropogenic emissions, and this increase is made responsible for the rising

temperature over the Industrial Era. Due to the far reaching consequences of this assertion, in this contribution we critically

scrutinize different carbon cycle models and compare them with observations. We further contrast them with an alternative

concept, which also includes temperature dependent natural emission and absorption with an uptake rate scaling proportional

with the CO2 concentration. We show that this approach is in agreement with all observations, and under this premise not really

human activities are responsible for the observed CO2 increase and the expected temperature rise in the atmosphere, but just

opposite the temperature itself dominantly controls the CO2 increase. Therefore, not CO2 but primarily native impacts are

responsible for any observed climate changes.

Human CO2 Emissions Have Little Effect on Atmospheric CO2

by Edwin X Berry , June, 2019 in JAtmOceanSciences


Abstract
The United Nations Intergovernmental Panel on Climate Change (IPCC) agrees human CO2 is only 5 percent and natural CO2 is 95 percent of the CO2 inflow into the atmosphere. The ratio of human to natural CO2 in the atmosphere must equal the ratio of the inflows. Yet IPCC claims human CO2 has caused all the rise in atmospheric CO2 above 280 ppm, which is now 130 ppm or 32 percent of today’s atmospheric CO2. To cause the human 5 percent to become 32 percent in the atmosphere, the IPCC model treats human and natural CO2 differently, which is impossible because the molecules are identical. IPCC’s Bern model artificially traps human CO2 in the atmosphere while it lets natural CO2 flow freely out of the atmosphere. By contrast, a simple Physics Model treats all CO2 molecules the same, as it should, and shows how CO2 flows through the atmosphere and produces a balance level where outflow equals inflow. Thereafter, if inflow is constant, level remains constant. The Physics Model has only one hypothesis, that outflow is proportional to level. The Physics Model exactly replicates the 14C data from 1970 to 2014 with only two physical parameters: balance level and e-time. The 14C data trace how CO2 flows out of the atmosphere. The Physics Model shows the 14 CO2 e-time is a constant 16.5 years. Other data show e-time for 12CO2 is about 4 to 5 years. IPCC claims human CO2 reduces ocean buffer capacity. But that would increase e-time. The constant e-time proves IPCC’s claim is false. IPCC argues that the human-caused reduction of 14C and 13C in the atmosphere prove human CO2 causes all the increase in atmospheric CO2. However, numbers show these isotope data support the Physics Model and reject the IPCC model. The Physics Model shows how inflows of human and natural CO2 into the atmosphere set balance levels proportional to their inflows. Each balance level remains constant if its inflow remains constant. Continued constant CO2 emissions do not add more CO2 to the atmosphere. No CO2 accumulates in the atmosphere. Present human CO2 inflow produces a balance level of about 18 ppm. Present natural CO2inflow produces a balance level of about 392 ppm. Human CO2 is insignificant to the increase of CO2 in the atmosphere. Increased natural CO2 inflow has increased the level of CO2 in the atmosphere.

THE FUTILITY OF WESTERN DE-CARBONISATION

It is clear that CO2 emissions are continuing to grow incrementally in the Developing World.  This should be anticipated to continue indefinitely.

2018 Global CO2 emissions

The following calculations and graphics are based on information on worldwide CO2 emissions published by BP in June 2019 for the period from 1965 up until the end of 2018.

The pie diagram above shows the proportion of CO2 emissions as of the end of 2018.

The previous post for the end of 2017 is available here

The data showing the progress of CO2 emissions by 2018 in the Developed and Developing worlds can be summarised as follows:

Statistical Review of World Energy

by BP, June 15, 2019


Global primary energy consumption grew rapidly in 2018, led by natural gas and renewables. Nevertheless, carbon emissions rose at their highest rate for seven years

Energy developments

  • Primary energy consumption grew at a rate of 2.9% last year, almost double its 10-year average of 1.5% per year, and the fastest since 2010.
  • By fuel, energy consumption growth was driven by natural gas, which contributed more than 40% of the increase. All fuels grew faster than their 10-year averages, apart from renewables, although renewables still accounted for the second largest increment to energy growth.
  • China, the US and India together accounted for more than two thirds of the global increase in energy demand, with US consumption expanding at its fastest rate for 30 years.

 

Carbon emissions

  • Carbon emissions grew by 2.0%, the fastest growth for seven years.

The major emitters that are meeting their Paris Agreement pledges

by Axios, June 1, 2019


Of top 10 global carbon emitters, not a single one is hitting its climate goals as outlined under the Paris Agreement, per data from the Climate Action Tracker.

Why it matters: Even if every country that’s adopted the Paris Agreement were to meet their pledges, it would not avert the worst effects of climate change.

Driving the news: June 1 marks the 2-year anniversary of President Trump’s announcement that the U.S. would withdraw from the deal. Per the Climate Action Tracker, the U.S., the second-largest world emitter of greenhouse gasses (but top historical emitter), falls under “critically insufficient,” the worst category, in meeting its Paris pledge.

The backdrop: The Paris Agreement’s main goal is to keep global temperature rise this century to “well below 2ºC,” above pre-industrial levels, and pursue efforts to limit the temperature increase to 1.5ºC.

  • Each country determined what it would be willing to do under the agreement. Such commitments are known as intended nationally determined contributions (INDCs).
  • After ratifying the agreement, the INDC would become the country’s first nationally determined contribution.

So far, 185 countries have ratified or adopted the Paris Agreement. All of the NDCs are available here.

Small increase in EU’s total greenhouse gas emissions in 2017, with transport emissions up for the fourth consecutive year

by European Environment Agency, May 29, 2019


Total greenhouse gas emissions in the European Union (EU) increased by 0.7 % in 2017, according to latest official data published today by the European Environment Agency (EEA). Less coal was used to produce heat and electricity but this was offset by higher industrial and transport emissions, the latter increasing for the fourth consecutive year.

According to the EEA’s Annual European Union greenhouse gas inventory 1990-2017 and inventory report 2019, total greenhouse gas emissions (including international aviation) rose by 0.7 % in 2017 compared with 2016. These official data confirm the preliminary estimates published by the EEA in October 2018. From 1990 to 2017, the EU reduced its net greenhouse gas emissions by 21.7 %. The EU is therefore still exceeding its 20 % reduction target set for 2020.
