Northeastern China was at least 5°C (and up to 9°C) warmer than today and droughts (and floods) were far more extreme when CO2 levels were a “safe” 265 ppm. In a new study, scientists have determined that northeastern China’s droughts were far more frequent and intense during the Little Ice Age (LIA) than in the […]

Fundamental assumptions in projections of alarming, CO2-induced global warming in the coming decades are undermined by a new long-term energy budget analysis. In a new study scientists have acknowledged the modeled assumptions forecasting nature’s response to the presumed human-driven radiative forcing of ocean heat uptake, thermal expansion, and sea level rise rates do not align […]

A new study finds Earth’s bottom water temperatures (BWTs) have cooled by 2-3°C over the last 4.5 million years through to the pre-industrial era (1750). Since 1750, however, global BWTs have not risen in a detectable way, nor have they exceeded the warmth achieved during the Medieval Warm Period (Gebbie and Huybers, 2019). The Pacific […]

It is widely acknowledged that the enhanced CO2 fertilization effect due to the modern rise in atmospheric CO2 is the predominant driver of the dramatic increases in global greening, or “gross primary production” (GPP). Global greening attribution estimates for CO2 fertilization range from 70% (Zhu et al., 2016) to 86% (Haverd et al., 2020). As […]

According to a new study, Greenland temperature stations indicate there was an abrupt 2.9°C warming trend from 1922-1932 (10 years) that was almost identical to the 3.1°C warming trend from 1993-2007 (14 years). Between the two warming periods (identified as WP1 and WP2 in the study) was an overall ~3°C cooling from 1933-1992. Thus, as […]

A new study indicates the Antarctic Peninsula has cooled -2.2°C (-1.2°C/decade) from 2003-2021. Of the 12 regions of Antarctica analyzed for temperature trends from 2003-2021, 6 cooled and 6 warmed. These trends undermine alarmist claims of CO2-induced “polar amplification.” Image Source: Nielsen et al., 2025

Another alarmist narrative debunked by observations. Coral coverage was supposed to be existentially devastated by the modern tenths-of-a-degree increases in sea surface temperatures and recurring bleaching events. However, a new study points to assessments of coral cover percentages in the Great Barrier Reef and concludes is “at its highest since monitoring began in 1985.” Further, […]

Approximately 75% of the increase in the global ocean heat content must be natural, or attributed to an increase in solar forcing. The manifestation of what is commonly referred to as “global warming” is predominantly (93%) depicted as an increase in ocean heat content (OHC). Only 1% is indicated by an increase in surface air […]

Alarmists claim that, due to anthropogenic climate change (AGW), the Atlantic Meridional Overturning Circulation (AMOC) is weakening to the point that it’s on the verge of collapsing. It’s claimed this will lead to abrupt cooling and extreme weather in the North Atlantic region. But the author of a new study points out that changes in […]

The push to transition to “green” energy technologies threatens to further entrench the long history of global inequalities and Western domination and exploitation. Vast quantities of raw materials (such as cobalt, nickel, lithium) are required to supply the European Union’s demands for “green” energy – battery production and green hydrogen deployment – over the coming […]

“Observations show no significant decline in Arctic sea ice concentration (SIC) since 2012…revealing a negligible trend of -0.4% per decade…” – Wang et al., 2025 Scientists are now acknowledging the sharply declining trend in Arctic sea ice from the mid-1990s to 2010s (-11.3% per decade), as well as the “negligible” or flat trend since 2012 […]

The mechanisms driving the meters-higher sea levels a few thousand years ago do not support claims that CO2 is a driver. A comprehensive analysis (Zhang et al., 2025) of the South China Sea region indicates warmer sea water was fundamentally responsible for sea levels that were, on average, 2-3 meters higher (and in some regions […]
