Antartica cooling and gaining ice
Antarctic cooling is a uniquely regional phenomenon. The original
study observed regional cooling in east Antarctica. The hole in the ozone layer above the Pole causes increased circular winds around the continent
preventing warmer air from reaching eastern Antarctica and the Antarctic plateau.
The flip side of this is the Antarctic Peninsula has "experienced some of the fastest warming on Earth, nearly 3°C over the last
half-century". While East Antartica is gaining ice, Antartica is overall
losing ice. This is mostly due to melting in West Antarctica which recently had the largest melting observed by satellites in the last 30 years.
Studies of ice cores show that carbon dioxide levels rise and fall with or after (as much as 1000 years) temperature
variations. This argument assumes that current climate
change can be expected to be similar to past climate change. While it is generally agreed that variations before the industrial age are mostly timed by
astronomical forcing, the current variations, of whatever size, are
claimed to be timed by anthropogenic releases of CO2 (thus returning the argument to the importance of human CO2 emissions). Analysis
of carbon isotopes in atmospheric CO2 shows that the recent observed CO2 increase cannot have come from the oceans, volcanoes, or the
biosphere, and thus is not a response to rising temperatures as would be required if the same processes creating past lags were active now.

So has spring ever backed up her "97% of climatologists believe in man made global warming" bit?

The study released today was conducted by academics from the University of Illinois, who used an online questionnaire of nine questions.

The Petition Project classifies petition signers on the basis of their formal academic training, as summarized below. Scientists often pursue specialized
fields of endeavor that are different from their formal education, but their underlying training can be applied to any scientific field in which they become

It's just more rightwing hot air about science ("What's this volcano monitoring?") because the new guidelines are that only unused embryos
from IVF clinics are to be used. No one is creating embryos just to be used for a stem cell line.
