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.
Scientists at the Chinese Academy of Sciences have put together the first global carbon dioxide maps based on data from the Chinese satellite TanSat. The satellite also measures what lead researcher Yang Dongxu calls “carbon dioxide flux,” changes in its behavior on Earth and in the Earth’s atmosphere.
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.
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?
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
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.

Could someone explain in 100 words or less without complex algebraic formulas how the trace gases, approximately 1% of the atmosphere can overtly control the temperatures of the remaining 99% atmospheric constituents?
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.
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.

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.
Huffington Post has noticed that many university academics are utter climate hypocrites, that many of them rate their personal importance by how many professional air miles they can accumulate every year (…)
The thousands of metric tons of carbon dioxide (CO2) emitted from power plants each year doesn’t have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels. On March 29 in the journal Joule, a team of Canadian and US scientists describe their vision for what we should make with CO2 and how we can make it.

The two strongest potentially credible constraints, and conclusions
In Part 1 of this article the nature and validity of emergent constraints[1] on equilibrium climate sensitivity (ECS) in GCMs were discussed, drawing mainly on the analysis and assessment of 19 such constraints in Caldwell et al. (2018),[2] who concluded that only four of them were credible. An extract of the rows of Table 1 of Part 1 detailing those four emergent constraints is given below.[3]
WUWT readers may recall this chart which clearly illustrates just how uncertain climate science really is.

Climate sensitivity – reducing the uncertainty of uncertainty
by Jon Cartwright
A study published in January 2018 claims to halve the uncertainty around how much our planet’s temperature will change in response to rising carbon dioxide (CO2) levels, potentially giving governments more confidence to prepare for the future.
In June 23, 1988 the Senate Committee on Energy and Natural Resources held a hearing addressing the Greenhouse Effect and Global Climate Change.
Among the presenters at this hearing was Dr. James Hansen, Director, NASA Goddard Institute for Space Studies who introduced his infamous and now debunked global surface temperature model results with future temperature projections under three different scenarios of CO2 emissions growth that grossly over exaggerated resulting projected global temperature increases.
Yet Germany’s image as selfless defender of the climate, which was once largely deserved, is now a transparent fiction. Germany has fallen badly behind on its pledges to sink its own greenhouse gas pollutants. In fact, Germany’s carbon emissions haven’t declined for nearly a decade and the German Environment Agency calculated that Germany emitted 906 million tons of CO2 in 2016 — the highest in Europe — compared to 902 million in 2015. And 2017’s interim numbers suggest emissions are going to tick up again this year.
Not quite a year ago (April 18, 2017) I authored a post on the completion of the Petra Nova carbon capture project at the W. A. Parrish coal-fired power plant in Fort Bend County, Texas. Petra Nova was billed as “the largest post-combustion carbon capture project in the world.” In addition to capturing CO2 from a very large coal-fired power plant, Petra Nova was also designed to serve a useful purpose: Deliver CO2 for enhanced oil recovery to West Ranch Oil Field in Jackson County, Texas. The ultimate goal is to boost production in the field from around 500 barrels of oil per day (BOPD) to 15,000 BOPD and recover about 60 million barrels that would otherwise have been left in the ground.
EIA had an update on the carbon capture aspect back in October…

Antarctic ice cores show regular swings in temperature of more than 20 degrees. These were all natural, but the recent zero degree swing was caused by your SUV (…)
As the Earth’s surface and atmosphere warm, the amount of moisture – water vapour – in the atmosphere will increase. Understanding the size of this increase is important for predicting future climates as water vapour is a significant greenhouse gas. Atmospheric moisture content also influences the patterns and intensity of rainfall events.
The relationship between temperature and moisture content can be explored by the study of intervals in Earth’s history when climates where significantly warmer than those seen in modern times, which necessitates a method for estimating ancient atmospheric moisture content.
European Union nations are poised to endorse the biggest overhaul of the market they created more than a decade ago to rein in pollution, a move that may lift prices of power generated from fossil fuels.
The measures, due for final approval in Brussels on Tuesday, impose tougher requirements on thousands of companies to reduce greenhouse gases or pay higher costs for their carbon dioxide emissions. They’re part of a plan to clear up a flaw in the market that left the cost of CO2 permits well below the level needed to stir investments in green energy.

These are the highlights:
The speed of the energy transition is uncertain and the new Outlook considers a range of scenarios. Its evolving transition (ET) scenario, which assumes that government policies, technologies and societal preferences evolve in a manner and speed similar to the recent past, expects
From the EUROPEAN COMMISSION JOINT RESEARCH CENTRE and the “Dr. Roger Pielke Sr. was right” department. I suspect a whole bunch of climate models that don’t take this into consideration, and think CO2 is the dominant climate driver, are going to need to be revised.
Land use change has warmed the Earth’s surface
Natural ecosystems play a crucial role in helping combat climate change, air pollution and soil erosion. A new study by a team of researchers from the Joint Research Centre, the European Commission’s science and knowledge service, sheds light on another, less well-known aspect of how these ecosystems, and forests in particular, can protect our planet against global warming.
A recently highlighted paper published by atmospheric scientists Scafetta et al., (2017) featured a graph (above) documenting post-2000 trends in the published estimates of the Earth’s climate sensitivity to a doubling of CO2 concentrations (from 280 parts per million to 560 ppm).
