Unsurprisingly, 2014 was the warmest year so far in the incremental record, as measured by NOAA and NASA. A few quick observations
* It’s silly to base global judgements on local observations. Still, living through January 2015 in Queensland, it’s easy to believe that the warming trend has continued into the New Year
* There’s nothing special about a calendar year. The first part of 2014, particularly February, was cooler than the rest of the year. So, it’s a safe bet that the 12 months ending Feb 2015 will be even warmer than the 12 months ending Dec 2014
* The biggest source of short-term fluctuations is the El Nino cycle, responsible for the very warm year in 1998 that is the basis for so much silly talk about “no global warming for x years”. 2014 was the first record year without a full-scale El Nino, though it kept threatening to emerge. Predictions are mixed for 2015.
* Of course, this long-expected news had no effect on denialists. But, like anti-vaxers, they are no longer getting the kind of “balanced” hearing they have counted on for so long, at least outside the Murdoch press. It’s now generally recognised that climate science denial isn’t a scientific viewpoint but a tribal shibboleth, and this is reflected in news coverage.
