Comments on: A winter’s tale of climate skepticism Global environmental challenges Wed, 16 Nov 2016 08:14:55 +0000 hourly 1 By: ajulius Sat, 12 Feb 2011 19:26:51 +0000 I keep reading the statement that global warming has increased atmospheric moisture, and therefore heavy snowfalls are to be expected. It is true that warmer air holds more water vapor, but it can’t snow unless it is below freezing. So heavy snowfalls would be evidence for global warming if they occur in regions where it is usually too cold to snow much. But the heavy snowfalls of the last two winters have largely been in the South, where it usually does not snow at all. The heavy snowfalls have been accompanied by colder than normal weather. This has nothing to do with global warming. The unusual snowfalls have been caused by a persistent negative phase of the North Atlantic Oscillation (NAO) which drives cold air south into the southeast US and southwest from Siberia into Western Europe. The negative NAO may be related to abnormally low sunspot activity, but this is still in dispute.

So if there is a particularly nasty winter, or apparently back to back winters, or even more consecutive bad weather it apparently never registers as ‘climate’.

On the other hand data collected from worldwide sensors while we’re freezing to death, tells us the weather is ‘torrid’. But is one year’s hot temperatures ‘climate change/’

So when does ‘weather’ become ‘climate’…does it require 1 year, ten years, a hundred years? It seems alot like cherry picking to me.
