The net climate forcing from albedo changes can account for the increase in ocean heat content in recent decades. Scientists (Goode et al., 2021) have determined Earth’s albedo declined from 1998-2017, driving a +0.5 W/m² net increase in absorbed solar radiation,...
A new study affirms Europe’s worst one-year droughts of the 21st century (2003, 2015, and 2018) have been far less severe than the 50+ consecutive years of “megadroughts” linked to the solar-minima-induced coldest decades of the 15th to 19th centuries. There...
Dozens of rapid warming and cooling periods episodically occurred throughout the last glacial. However, they have often been dismissed as local-only events. A 2020 study published in Science robustly affirms steeper-than-today warming periods spanned both hemispheres and 23 of 25 were...
A professor of hydrology from the University of Athens eviscerates the “naïve” paradigm that says the natural state of Earth’s climate is constancy and stability, only changing when an “external agent” (i.e., a rapid increase in fossil fuel emissions ) acts...
A new study asserts that when Greenland naturally warms by multiple degrees per decade, this “abrupt climate variability can result entirely from unforced or noise-induced oscillations of the coupled atmosphere-ice-ocean system.” This means the recent modest climate changes for Greenland may...
Africa climate variability linked to natural oceanic and solar cycles, a new study affirms. No mention of CO2. Image source: “Decadal and multidecadal natural variability of African rainfall“. A new study analyzes patterns of natural rainfall variability and can provide crucial...
An assessment of the 1856-2012 drought frequency/intensity along the US West Coast leaves no role for human activity in hydroclimate. Across the globe, no clear precipitation trends have been observed in the last several decades (Nguyen et al., 2018) Image Source:...
Scientists are increasingly finding that abrupt, decadal-scale temperature changes of multiple degrees Celsius can arise unforced and spontaneously. The surface temperatures for the Greenland ice sheet have been known to warm 8 to 16°C “within decades or less” – yes, fewer...
A new assumption about carbon budgets reveals climate scientists have been vastly underestimating (by a factor of 2) the amount of carbon absorbed by the ocean for decades. Every past carbon budget estimate has been twice as wrong as the current...
A new paper reveals that climate models have failed to take important natural factors, such as the North Atlantic Oscillation, into account in their climate models on which leaders have been basing their policies. A new paper in Nature says NAO...
