New study: Antarctic and Greenland ice sheet melt may be natural event, no consensus on cause

Ice sheets are the largest potential source of future sea level rise – and they also possess the largest uncertainty over their future behaviour From the University of Bristol Continuous satellite monitoring of ice sheets needed to better predict sea-level … Continue reading

‘Game changer’ – Antarctic melt due to warm water, not air temperature

From the University of California – Irvine  something that pretty well makes Steig et al 2009 even more irrelevant, since in that paper they did a survey of air temperatures and then smeared them around the continent using some Mannian … Continue reading

Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide

From the University of Waterloo, an extraordinary claim. While plausible, due to the fact that CFC’s have very high GWP numbers, their atmospheric concentrations compared to CO2 are quite low, and the radiative forcings they add are small by comparison … Continue reading

Bipolar disorder – as in the Arctic, the Antarctic sea ice extent is affected by wind, unless of course it’s ‘climate change’

From the “no matter what happens it is climate change” department. So, according to this, when the Arctic loses ice it is due to climate change ‘global warming’ when the Antarctic gains ice it is due to ‘climate change’ and … Continue reading

How GISS creates long term Antarctic warming

From Tallblokes Talkshop, note what happens before 1958. HOW GISS MANUFACTURES WARMING (LOTS OF IT) IN THE ANTARCTIC by Roger Andrews The close match between GISS and me after 1955 is encouraging in that it shows that there’s at least … Continue reading

New research in Antarctica shows CO2 follows temperature “by a few hundred years at most”

The question of “which comes first, the temperature or the CO2 rise?” has been much like the proverbial “which came first, the chicken or the egg?” question. This seems to settle it – temperature came first, followed by an increase … Continue reading

Dear Woods Hole and NCAR, maybe you missed this trend in Antarctic sea ice?

More modeling madness projecting the future, but the actual data for the past 30 years says otherwise, with a positive trend. Regular commenter Julienne Stroeve of NSIDC is one of the co-authors, so perhaps she’ll weigh in here. The article … Continue reading

NASA: Study Finds Ancient Warming Greened Antarctica

It seems Antarctica once had vegetation and had a lot of rain. This artist’s rendition created from a photograph of Antarctica shows what Antarctica possibly looked like during the middle Miocene epoch, based on pollen fossil data. Image credit: NASA/JPL-Caltech/Dr. … Continue reading

NASA: Warm Ocean Currents Cause Majority of Ice Loss from Antarctica

Breaking news from NASA and the ICEsat team, that’s their headline, not mine. This really makes all the hype over the now discredited Steig et al. paper, which attempted to establish an air temperature warming trend as one of the … Continue reading

Did Shakun et al. really prove that CO2 preceded late glacial warming? [Part 1]

By Don J. Easterbrook, PhD. In a paper “Global warming preceded by increasing carbon dioxide concentrations during the last deglaciation”, Shakun et al.(Nature 2012) contend that rising temperature at the end of the last Pleistocene glaciation were preceded by increasing … Continue reading
