Claim: Last 100 years may be warmest in 120,000 years in the Arctic, but not so fast (UPDATED)

From the University of Colorado at Boulder, comes this study about radiocarbon dating some dead moss clumps exposed from under ice/snow at 4 locations on Baffin Island that somehow proves “unprecedented” warmth for the entire Arctic for the last 120,000 … Continue reading

Alaska’s Columbia Glacier expected to halt retreat in 2020

From the University of Colorado at Boulder more model output, but at least this is a testable hypothesis in the not too distant future. It also points to the fact that there is not a definitive linear relationship between CO2 … Continue reading

Earth’s CO2 sinks increasing their uptake

Readers may recall these WUWT stories:  Earth’s biosphere booming,  California’s giant redwoods inconveniently respond to increased carbon dioxide, and Forget deforestation: The world’s woodland is getting denser and change could help combat climate change. NASA satellite imagery pointed this out long ago. … Continue reading

Reanalyses find rising humidity in the Arctic

Direct, reliable observations of atmospheric conditions stretch as far back as the mid seventeenth century, with otherwise consistent records being punctuated by periodic updates in methods, practitioners, and observational equipment. To bridge these shifts in technique and technology, scientists develop … Continue reading

New paper speculates on volcanoes during the Little Ice Age

From NCAR/UCAR, they’re still trying to stamp out solar influence as a potential cause of the Little Ice Age. One of the things I wonder about is that during low sunspot activity, does the reduced solar-magnetic influence have any effect … Continue reading
