1. Statements about climate trends must be based on, er, trends. Not individual events or occurrences. Weather is not climate, and anecdotes are not statistics.
2. Global warming is actually expected to increase "heavy precipitation in winter storms," and for the northern hemisphere, there is evidence that these storms are already more frequent and intense, according to the draft US National Climate Assessment.
3. Antarctica is a very cold place. But global warming is affecting it as predicted: Antarctica is losing ice overall, according to the latest report of the Intergovernmental Panel on Climate Change. However, sea ice is a different matter than land-based or glacial ice. Antarctic sea ice is increasing, and moreover, the reason for this may be climate change! (For more, read here.)
“A politically motivated, decades-long war on expertise has eroded the popular consensus on a wide variety of scientifically validated topics,” writes Suzanne LaBarre. “Everything, from evolution to the origins of climate change, is mistakenly up for grabs again. Scientific certainty is just another thing for two people to ‘debate’ on television. And because comments sections tend to be a grotesque reflection of the media culture surrounding them, the cynical work of undermining bedrock scientific doctrine is now being done beneath our own stories, within a website devoted to championing science.”
