The United Nations Intergovernmental Panel on Climate Change (IPCC) claims that unless we reduce or eliminate carbon dioxide emissions from burning fossil fuels and keep global temperature rise to less than 1.5°C, the planet will become uninhabitable. They ignore the fact that carbon dioxide emissions from burning fossil fuels constitute just over 0.1% of total greenhouse gases (See article here). They also ignore the fact that for much of the past 600 million years global temperature has been 12°C warmer than now and life has flourished (see figure below). The IPCC is as political organization, not a scientific one. All their climate models run hotter than real observations and all their doomsday predictions have not come to pass.
Here are some comments on the IPCC report:
Heartland Institute Climate Experts React to Latest UN IPCC Report
APRIL 7, 2022
By H. Sterling Burnett, James Taylor, Linnea Lueken, Tim Benson, Anthony Watts
The IPCC has been scandalously wrong regarding virtually all of their past predictions. There is no reason to believe this version will be any more accurate.
The United Nations Intergovernmental Panel on Climate Change (IPCC) released its Sixth Assessment Report (AR6) this week. IPCC chairman Hoesung Lee claimed “we are at a crossroads” but need to start reducing overall global emissions of carbon dioxide after 2025 to “secure a livable future.” UN Secretary-General António Guterres said unless we dramatically reduce CO2 emissions, humanity faces a future of “unprecedented heatwaves, terrifying storms, widespread water shortages and the extinction of a million species of plants and animals.”
Climate science and policy experts at The Heartland Institute strongly disagree with this assessment. The Heartland Institute is the world’s most-prominent think tank promoting the work of scientists and other experts who do not think human activity is causing a climate crisis.
The IPCC report is tantamount to ‘old whine (pun intended), in new bottles.’ There is nothing truly new in this report. It makes the same unsubstantiated claims of doom, and the same unsubstantiated claims that we can act now, to, in a very short time period, end the use of fossil fuels to save the earth, and profit in the process. The projections of climate models have repeatedly proven inaccurate, and the resources simply do not exist to – in the time frame the IPCC says saving the planet demands – remake the entire global economy sans fossil fuels. In the process of trying, we would destroy the environment by mining, erecting wind turbines and solar arrays, to save it. (Read more)
The Many Benefits of Rising Atmospheric CO2 — An Introduction
By Craig D. Idso — April 6, 2022
Dr. Craig Idso, Chairman of the Center for the Study of Carbon Dioxide and Global Change, and a new principal at MasterResource, invites readers to join him in a new series of articles discussing the many ways in which rising atmospheric carbon dioxide benefits humanity and nature.
Atmospheric carbon dioxide: you can’t see, hear, smell or taste it. But it’s there—all around us—and it’s crucial for life. Composed of one carbon and two oxygen atoms, this simple molecule serves as the primary raw material out of which plants construct their tissues, which in turn provide the materials out of which animals construct theirs. Knowledge of the key life-giving and life-sustaining role played by carbon dioxide, or CO2, is so well established, in fact, that humans—and all the rest of the biosphere—are described in the most basic of terms as carbon-based lifeforms. We simply could not and would not exist without it.
Ironically, far too many demonize and falsely label this important atmospheric trace gas a pollutant. Nothing could be further from the truth. Instead of being shunned like the plague, the ongoing rise in CO2 should be welcomed with open arms. (Read more)
Study: More Evidence Of Climate Model Heat Biases
Professor Nicola Scaffeta of the University of Naples Department of Earth Sciences has just published a detailed, peer-reviewed assessment of the latest generation of global climate models. He begins by noting that there are about 40 major climate models and their climate sensitivity levels vary by a factor of three, from 1.8 to 5.7 degrees C per doubling of carbon dioxide.
Which right away tells you there is a lot of guesswork going on. He groups the models into low-, medium-, and high-sensitivity categories and asks a simple question: how well did the models do at reproducing the warming from 1980 to 2021? Among the high-sensitivity models, they got the pattern wrong for over 80 percent of the Earth’s surface. The medium-sensitivity models did better, but they were still wrong for over 68 percent of the Earth’s surface. Finally, the low-sensitivity models did the best, but they were wrong on 60 percent of the Earth’s surface. (Read more)
Reality Cannot Penetrate Into The Fantasy World Of Climate Campaigners
by Francis Menton
It was only a few weeks ago when the UN’s International Energy Agency issued its Report on “CO2 Emissions in 2021.” I covered the IEA’s Report in my previous post a few days ago. The Report gives detail as to the obvious fact that world CO2 emissions, after a downward blip in 2020 due to the Covid pandemic, have resumed their rapid increase, mostly attributable to massive deployment of coal-fired electricity generation resources in large-population developing countries like China and India. In any rational world, this Report would have to have dashed any remaining dreams of climate campaigners that overall world CO2 emissions would see anything but large ongoing increases for the foreseeable future. The climate-obsessed jurisdictions in the U.S. and Europe already represent only a shrinking minority of world energy consumption, headed for insignificance as the large-population countries of the developing world join the fossil fuel age.

Compared to the past, Earths temperatures are low now because we are in an ice age, but fortunately in an interglacial period.
The following shows the output of climate models compared to reality.
