By Andy May For decades We have been told that we must not let global warming exceed two degrees Celsius above the “pre-industrial” global average temperature. Recently the IPCC lowered this limit to 1.5°C. In the latest IPCC report, called AR6, pre-industrial is defined as before 1750, but they use global temperatures from 1850-1900 as representative [...]
by Roy W. Spencer, Ph. D. reposted from his blog Summary The simple CO2 budget model I introduced in 2019 is updated with the latest Mauna Loa measurements of atmospheric CO2 and with new Energy Information Administration estimates of global CO2 emissions through 2050. The model suggests that atmospheric CO2 will barely [...]
Reposted from the Manhattan Contrarian By Francis Menton The Supreme Court’s West Virginia v. EPA decision a couple of weeks ago has brought forth a big wave of hand wringing in the precincts of the left. How oh how are we now going to save the planet, if our friends at the EPA [...]
"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman Despite the claims of activists and the mainstream media that climate change is making major hurricanes – such as U.S. Hurricane Harvey in 2017 or Hurricane Katrina in 2005 – more frequent and stronger, several recent [...]
You’ve probably heard that methane, one of the minor greenhouse gases, allegedly makes an outsized contribution to global warming. But the current obsession with methane emissions is totally unwarranted and based on a fundamental misunderstanding of basic physics. This misconception has been explained in detail by atmospheric physicists William Happer and William van [...]
The big-tech censors are at it again: the CO2 Coalition’s Executive Director Gregory Wrightstone has been permanently banned from LinkedIn. What did Wrightstone do to earn the banishment? His “crime” consisted of posting charts from peer reviewed research supported by official sources demonstrating that current global average CO2 levels are well within the natural range of [...]
By Andy May The U.S. Constitution was finally approved in 1787, after much debate. It reserved a specific list of powers for the federal government and the first ten amendments, or the “Bill of Rights,” reserved many powers for the citizens and states. The Bill of Rights imposed clear limitations on the federal [...]
Guest Post by Renee Hannon Introduction This post examines sample spacing for CO2 measurements in Antarctic ice cores during the past 800,000 years to better understand if gaps in sampling are too large to capture centennial fluctuations. The IPCC states: “Although ice core records present low-pass filtered time series due to gas diffusion and [...]
U.S. progressives are convinced that fossil fuels must be replaced with renewables by 2050. The IEA even has a plan to do it. How will this work? Unlike progressives we value observational data over ideology, so let’s examine the data. According to ExxonMobil’s 2021 Outlook for Energy the world consumed 89.4 BBOE (billions of barrels of oil equivalent) of primary [...]
By Andy May An interesting PNAS article discusses the deepest portion of the Camp Century Greenland Ice core. It is not paywalled. The researchers, led by Andrew Christ (Dept. of Geology, University of Vermont) found evidence of an ice-free vegetated environment at the base of the Camp Century ice core roughly one million years ago. This [...]
