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 years. See below for my take on it. CU-Boulder study shows unprecedented warmth in Arctic…

Using a climate model to map global atmospheric conductivity

From the University of Colorado at Boulder CU-Boulder researchers use climate model to better understand electricity in the air Electrical currents born from thunderstorms are able to flow through the atmosphere and around the globe, causing a detectable electrification of the air even in places with no thunderstorm activity. But until recently, scientists have not…

Claim: Faint Young Sun Paradox solved

From the University of Colorado at Boulder a claim that computer modeling has solved the problem, with an atmosphere that is 20,000 parts per million of  CO2 and 1,000 ppm of methane. CU study shows how early Earth kept warm enough to support life Scientists tackle faint young sun paradox with 3-D climate models Solving…

NOAA exaggerates 2012 Greenland Ice Mass Loss by 10x

[UPDATE: Several commenters, including myself, have remarked on a mathematical error in the author’s work. I note this here in the expectation that the author will return to clarify and perhaps amend his claims. Having made such public mistakes myself, it’s embarrassing if true, but that’s the function of public peer review as practiced on…

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 and individual glacier retreat, if there were, it would continue unabated. The wild and dramatic…

Climate not a significant factor in East African conflicts

From the University of Colorado at Boulder, another overhyped climate meme has been put to rest by a new study that made some obvious findings about temperature and rainfall as it relates to human behavior, but more importantly in human events “…political and geographic factors play a much more substantial role than climate change.” Climate…

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. Now confirmation from another source: From the University of Colorado at Boulder Earth absorbing more…

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 reanalysis models designed to tie together diverse observations into a coherent picture of the system’s…
