A “widespread greening trend” has been “significantly cooling the land surface” since the 1980s. Another new study documents a clearly-defined land surface greening trend over the last 40 years. The greening is linked to CO2 fertilization and climate change (warming). Greening, in turn, leads to land surface cooling, partially offsetting recent warming. Image Source: Li […]

The modern notion that human CO2 emissions are equivalent to a “deadly poison” may one day be viewed as “the greatest mass delusion in the history of the world.” In a new paper published in the Journal of Sustainable Development, Manheimer (2022) summarizes some of the evidence for the lack of correlation between CO2 and […]

Ruling forcing Shell to cut CO2 emissions did not take all the side of the science into account… Clintel Intervenes In Friends Of The Earth’s Shell Lawsuit By Andy May Friends of the Earth (Netherlands) sued Royal Dutch Shell, using The Netherlands law that allows non-governmental organizations to sue over environmental or social issues that […]

The longstanding claim is CO2 (greenhouse gas) top-of-atmosphere (TOA) forcing drives climate change. But it is too cold at the TOA for CO2 (or any greenhouse gas) to exist. Image Sources: Schneider et al., 2020, NASA, UCAR, CGA TOA greenhouse gas forcing is a fundamental tenet of the CO2-drives-climate-change belief system. And yet the “global-mean […]

If the error and uncertainty associated with determining the extent to which natural factors (aerosol forcing, downwelling shortwave variability) affect climate are factors of ten times larger than the presumed effects of human activity, then we cannot definitively say human activity is driving climate change. It takes 10 years and 22 ppm for CO2 forcing […]

Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.” – Marsz et al., 2022 Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the […]

The warming “predicted from climate models” has not materialized in yet another temperature record. In an “assessment of the performance of the climate projections” for all of Italy over the 1948-2021 period, we can observe no rising temperature trend (shown in green) that could align with the rise in CO2 emissions per a new study. […]

German physicists claim to have experimentally demonstrated the greenhouse effect from greenhouse gases like CO2 and CH4 is a real phenomenon, but assess the climate sensitivity to a doubling of CO2 with feedbacks is “only ECS = 0.7°C … 5.4x lower than the mean value of CMIP6 with ECS = 3.78°C.” “The derived forcing for […]

Two new studies indicate there has been no modern warming in the last centuries in western (Urals) and eastern (Kolyma) Russian mountain ranges. A new 27,000-year temperature reconstruction assesses it was ~2.5 to 4.8°C warmer than today from 8.9-5.2 ka BP in the Ural Mountains, or when CO2 is said to have hovered in the […]

Solution: Increase Ocean Evaporation (<4% of CO2 Reduction Cost) Guest poet by David R. Motes, November 10, 2022 Climate change is real and cycles over Earth’s geologic history. We are in a global warming trend for the past 140+ years. Contrary to prevailing climate theory, this man-made warming trend is primarily driven by a CO2 […]

An increase in effective radiative forcing from human activity is now said to be mostly driven by a decline in aerosol pollution, superseding the effects of CO2 emissions. The majority of an alleged acceleration in anthropogenic global warming in the 21st century “is driven by changes in the the aerosol [effective radiative forcing] trend, due […]

Annual carbon dioxide (CO2) and methane (CH4) change rates lag behind changes in sea ice extent by 7 months and 5 months, respectively. This robust correlation is consistent with the conclusion that CO2 (and CH4) changes are responsive to temperature, not the other way around. It is commonly believed that the annual “squiggle” of the […]
