Abstract excerpt: 'The eastern Antarctic and Antarctic plateau have cooled, primarily in summer, with warming over the Antarctic Peninsula and Patagonia . Moreover, sea-ice extent around Antarctica has modestly increased.'
Analysis: 'What we seem to be left with is a paper that uses computer simulations to find that global warming has managed to cool Antarctica, and lead to an increase in sea ice there. This is despite the fact that, according to the IPCC, the vast majority of models predict the opposite.'
'But what does the paper actually show? The paper compares ice volume changes between three different satellite altimetry databases. As the authors note, one must be very careful about drawing conclusions in comparing databases from different measurement sources and which use different analysis methods. In this case, the CryoSat satellite database only covers a very short 2011-early 2014 time period of a little over 3 years and does not overlap the ICESat database from 2003-2009 or the IMBIE database from 2003-2008.'
'Today, most scientists have concluded that the effects of acid rain were overstated to begin with—fewer lakes were hurt than had been thought, and acid rain was not the only cause.'
'Environmental issues became ways for politicians to signal their clan identity to supporters. As symbols, the issues couldn’t be compromised. Standing up for your side telegraphed your commitment to take back America—either from tyrannical liberal elitism or right-wing greed and fecklessness. Nothing got done.'
