Claim: U.N. data reflects greening of the Earth, not carbon dioxide

by A. Watts, May 15, 2018 in WUWT

NASA says the greening of the planet is due to increased CO2, these guys are arguing against that, saying increased forest growth “correlates strongly to the UN Development Programme’s Human Development Index”. Riiiighht. They say that “Europe’s early turnaround and expansion of forest resources obviously can’t be attributed to the rapid rise of atmospheric carbon dioxide that began decades later”. By the same token, the U.N. didn’t exist until decades later, and they sure as hell haven’t had any impact on the greening of the Eastern United States as shown in their map below (…)

In 2017, CO2 emissions in the EU estimated to have increased compared with 2016

by Eurostat-newrelease, May 4, 2018

Eurostat estimates that in 2017 carbon dioxide (CO2) emissions from fossil fuel combustion increased by 1.8% in the European Union (EU), compared with the previous year. CO2 emissions are a major contributor to global warming and account for around 80% of all EU greenhouse gas emissions. They are influenced by factors such as climate conditions, economic growth, size of the population, transport and industrial activities.

It should also be noted that imports and exports of energy products have an impact on CO2 emissions in the country where fossil fuels are burned: for example if coal is imported this leads to an increase in emissions, while if electricity is imported, it has no direct effect on emissions in the importing country, as these would be reported in the exporting country where it is produced.

This information on early estimates of CO2 emissions from energy use for 2017 is published by Eurostat, the statistical office of the European Union.

Largest falls in CO2 emissions in Finland and Denmark, highest increases in Malta and Estonia

According to Eurostat estimates, CO2 emissions rose in 2017 in a majority of EU Member States, with the highest increase being recorded in Malta (+12.8%), followed by Estonia (+11.3%), Bulgaria (+8.3%) Spain (+7.4%) andPortugal (+7.3%). Decreases were registered in seven Member States: Finland (-5.9%), Denmark (-5.8%), theUnited Kingdom (-3.2%), Ireland (-2.9%), Belgium (-2.4%), Latvia (-0.7%) and Germany (-0.2%)..

Efforts to decarbonise will kill millions in poor countries

by Mikko Paunio, May 5, 2015 in GWPF

The report (.pdf, 11 pages), by eminent epidemiologist Mikko Paunio, says that international bodies and NGOs are trying to prevent poor countries from expanding their use of conventional fuels, have abandoned the so-called “energy ladder”  — the gradual shift to cleaner types of fuel that underpinned the clean up of air quality in industrialised nations.

As Dr Paunio explains, this will have devastating consequences:

“Indoor air pollution from domestic fires kills millions every year. But instead of helping poor people to climb the energy ladder and clean the air in their communities, the poorest people are being given gimmicks like cookstoves, which make little difference to air quality, and solar panels, which are little more than a joke.”

NOAA US Data Tampering Update

by Tony Heller, May 2, 2018 in TheDeplorableClimateScience

Measured US temperatures show cooling over the last 90 years.  This doesn’t suit the needs of the climate mafia, so NOAA massively alters the data to turn cooling into warming.  NOAA cools the past by more than one degree, and warms the present by nearly one degree.  Then other climate scientists use this fake data to confirm fake theories about CO2 emissions warming the planet.

How Oman’s Rocks Could Help Save the Planet

by Henri Fountain, April 26, 2018 in TheNewYorkTimes

IBRA, Oman — In the arid vastness of this corner of the Arabian Peninsula, out where goats and the occasional camel roam, rocks form the backdrop practically every way you look.

But the stark outcrops and craggy ridges are more than just scenery. Some of these rocks are hard at work, naturally reacting with carbon dioxide from the atmosphere and turning it into stone.

Veins of white carbonate minerals run through slabs of dark rock like fat marbling a steak. Carbonate surrounds pebbles and cobbles, turning ordinary gravel into natural mosaics.

Even pooled spring water that has bubbled up through the rocks reacts with CO2 to produce an ice-like crust of carbonate that, if broken, re-forms within days.

Scientists say that if this natural process, called carbon mineralization, could be harnessed, accelerated and applied inexpensively on a huge scale — admittedly some very big “ifs” — it could help fight climate change. Rocks could remove some of the billions of tons of heat-trapping carbon dioxide that humans have pumped into the air since the beginning of the Industrial Age.

And by turning that CO2 into stone (…)

New Lewis & Curry Study Concludes Climate Sensitivity is Low

by Ph.D. Roy W. Spencer, Apritl 24, 2018 in Global Warming

Global warming “problem” cut by 50%

As readers here are aware, I don’t usually critique published climate papers unless they are especially important to the climate debate. Too many papers are either not that important, or not that convincing to me.

The holy grail of the climate debate is equilibrium climate sensitivity (ECS): just how much warming (and thus associated climate change) will occur in response to an eventual doubling of the CO2 concentration in the atmosphere?

Yesterday’s early online release of a new paper by Nicholas Lewis and Judith Curry (“The impact of recent forcing and ocean heat uptake data on estimates of climate sensitivity“, Journal of Climate) represents one of those seminal papers.

New paper finds strong evidence the Sun has controlled climate over the past 11,000 years, not CO2

by ‘hockeschtick‘, November 27, 2014

A paper published today in Journal of Atmospheric and Solar-Terrestrial Physics finds a “strong and stable correlation” between the millennial variations in sunspots and the temperature in Antarctica over the past 11,000 years. In stark contrast, the authors find no strong or stable correlation between temperature and CO2 over that same period.

We have thus shown
  • Strong correlation between solar activity and climate over the past 11,000 years of the Holocene
  • Strong lack of correlation between CO2 and climate over the past 11,000 years of the Holocene
  • Solar activity explains all 6 well-known warming periods that have occurred during the Holocene, including the current warm period
  • The 20th century peak in sunspot activity is associated with a 40 year lag in the peak global temperature

The impact of recent forcing and ocean heat uptake data on estimates of climate sensitivity

by J. Curry and N. Lewis, April 24, 2018 in ClimateAudit

There has been considerable scientific investigation of the magnitude of the warming of Earth’s climate by changes in atmospheric carbon dioxide (CO2) concentration. Two standard metrics summarize the sensitivity of global surface temperature to an externally imposed radiative forcing. Equilibrium climate sensitivity (ECS) represents the equilibrium change in surface temperature to a doubling of atmospheric CO2 concentration. Transient climate response (TCR), a shorter-term measure over 70 years, represents warming at the time CO2 concentration has doubled when it is increased by 1% a year.

Climate Scientists Recant

by K. Richard, April 19, 2018 in NoTricksZone

The Arctic region was the largest contributor to the positive slope in global temperatures in recent decades.

Consequently, the anomalously rapid warming in the Arctic region (that occurred prior to 2005) has been weighted more heavily in recent adjustments to instrumental temperature data (Cowtan and Way, 2013; Karl et al., 2015) so as to erase the 1998-2015 hiatus and instead produce a warming trend.

Meanwhile, other scientists have been busy determining that only about 50% of the warming and sea ice losses for the Arctic region are anthropogenic, or connected to the rise in CO2 concentrations.

The rest of the warming and ice declines can be attributed to unforced natural variability.

Top Climate Scientist: CO2 Model Assumptions “Invalid”…”Natural Climatic Variations Dominate”!

by P. Gosselin, April 6, 2018 in NoTricksZone

The addition of an esteemed Norwegian climate scientist to the London-based GWPF will help bring some sobriety back to a science that has all too often been immersed in alarmism.

The London-based Global Warming Policy Foundation (GWPF) recently announced Professor Ole Humlum of Norway was joining its Academic Advisory Council.

This brings another persuasive voice to the influential think tank.

Climate-Related Deaths Down by 98.9%; Last Year All-Time Low

by Bjorn Lomborg, April 2, 2018 in ClimateChangeDispatsch

CCD Editor’s Note: In 1920, CO2 levels were 303 PPM or 0.03%. Last year they were 406 PPM or 0.04%. Despite our global population quadrupling, climate deaths have actually gone down as CO2 levels have gone up. Lomborg explains why with the now-standard, often-by-rote “this does not mean that there is no global warming” caveat.
