Share this…FacebookTwitterThere are four main reasons why Antarctica’s Larsen C Ice Shelf may be melting. None of them involve human forcing or CO2 concentration changes. Scientists have recently completed an exhaustive 20-year study of the “most significant causes of melting” of the Larsen C Ice Shelf in the Antarctic Peninsula. They have concluded the 4 […]

Share this…FacebookTwitterGreenland’s climate changes are remarkably uncorrelated with climate model expectations and changes in atmospheric CO2. When CO2 levels were in the mid-200s parts per million (11.7 to 4.5 thousand years ago) the Arctic and northern Greenland were 2-4°C warmer than now, ice margins were 80 km behind today’s, ice-free open water conditions prevailed, and […]

Share this…FacebookTwitterThe increasing loss of ozone (O3) from 3o°N – 30°S has steadily accelerated since the early 1980s despite the 1987 Montreal Protocol’s ban on so-called “ozone depleting substances” like chlorofluorocarbons (CFCs). Once again this suggests human activity does not drive ozone losses. Twenty years after the Montreal Protocol agreement limiting or banning CFC use […]

Share this…FacebookTwitterNew research continues to document non-warming and even “robust cooling” trends for entire regions of the Southern Hemisphere in recent decades. Land surface temperature data compilations from the Southern Hemisphere (South America, Southwestern Andes, Tasmania, New Zealand, Australia) indicate that any warming during the 20th century occurred before 1980, with no obvious net warming […]

Share this…FacebookTwitterThe Pacific Ocean is 5 to 6 km deep. New research indicates the bottom half (2 km to the bottom) of the Pacific has been robustly cooling since 1993. A new preprint details the “surprising” Pacific cooling pattern from two ocean heat content (OHC) datasets over the 1993-2017 period. Most OHC records only extend […]

Share this…FacebookTwitterYet another new study documents the lack of regional cooperation with the “global” warming narrative. Since 1979 there has been no net warming in the South China Sea and no evidence of a hiatus or “growth discontinuity” in this region’s coral development (Tan et al., 2022). Natural ENSO variation leads changes in the sea […]

Share this…FacebookTwitterThe elevated CO2 fertilization effect is driving global greening trends, pushing back deserts, enhancing photosynthesis by 30 to 50%, improving water use efficiency, and boosting crop yields by about 3% every year since 1961. Recently atmospheric CO2 has been rising at a rate of about 3 ppm per year. While activists claim this is […]

Share this…FacebookTwitterThe accuracy of the long-term global instrumental temperature record – especially the data obtained before the 1970s – wholly rests on the assumption that sailors obtained precisely reliable temperature measurements as they pulled wooden or canvas buckets out of the water from ships at random depths, locations, and times of day. They didn’t. It […]

Share this…FacebookTwitterAbundant polar bear remains dating to 8000 to 9000 years ago have been found on Zhokhov Island, which is today surrounded by year-round sea ice (even in summer). This Arctic latitude (76°N) is too cold and thus too ice-covered for polar bears to inhabit today. During the Early Holocene CO2 concentrations ranged between 255 […]

Share this…FacebookTwitterNew studies identify sites in Portugal, southern Africa, and Arctic Svalbard that have not warmed in the last few centuries. Daily temperature records in northern Portugal indicate no net warming from 1863-2004 (Nunes, 2022). Also, the Medieval Warm Period was warmer than the 21st century at this location. Image Source: Nunes, 2022 Affirming this […]

Share this…FacebookTwitterA new study details how a much warmer climate than today led to the disappearance of glaciers and ice caps during the sub-300 ppm CO2 Early to Middle Holocene. The Arctic’s modern ice extent is among the largest of the last 10,000 years. Glaciologists Larocca and Axford (2022) have synthesized a comprehensive record of […]

Share this…FacebookTwitterA late 2021 study finds water vapor and temperature changes accounted for 90% of the changes in clear-sky downwelling longwave or greenhouse effect forcing since the mid-1980s. CO2 forcing assumed a mere bit-player role. The seminal Feldman et al. (2015) study concluded it takes 10 years and a 22 ppm increase in CO2 to […]
