New year, new theme (2016)

The new look, that is. The WordPress official theme of the year, and I like it enough to make it Hot Topic‘s new look. Simpler for me to maintain than the old, very customised theme, but it does mean we’ve lost the comment editing facility. Sorry about that. Meanwhile, please use this as an excuse to discuss whatever climate-related issues you like. More substantive posts may appear soon.

[Update #2 Feb 2nd: I may have tracked the comment issue down to a conflict with an anti-spam plug in. We’ll see… Thanks to Andy and Mr February for helping me try to diagnose the problem. GR]

[Update #3 Feb 4th: The Jetpack guys at WordPress are trying to unpick this problem. Thanks for your patience. GR]

[Update #4: Working again, but without “social log in” enabled, while WP fix the code. Thanks again to everyone who helped us diagnose the problem. GR]

[Update #5: And while we’re on the subject, please be warned that very long comments are difficult to post, because of a coding fault in the theme – basically the “post” button disappears… So try to keep your thoughts succinct, until the theme is updated. 😉 GR]

Too hot (and here comes the surge)

GISS20152015 was the hottest year since records began in all of the major global temperature datasets, and by a huge margin. The world is now more than 1ºC warmer than pre-industrial temperatures — pushed there by rapidly rising levels of greenhouse gases in the atmosphere, and helped a little by the current very strong El Niño. And because El Niño’s major impacts on global temperatures happen as an event declines, we can expect 2016 to be even warmer.

Carbon Brief has an excellent analysis of the new record here. See also NASA and NOAA’s joint announcement, the NASA press release, and Hansen et al’s overview (pdf). Here’s the latter on the outlook for the rest of the decade:

We can also say with confidence, because of Earth’s energy imbalance (energy absorbed from sunlight exceeding heat radiated to space), that the present decade will be warmer than last decade. Already the first half of the present decade is almost 0.1°C warmer than last decade. Strong La Niñas commonly follow strong El Niños, so it is likely that 2017 and perhaps 2018 will be quite cool relative to 2015-2016, but the decade as a whole should be considerably warmer than the prior decade.

Kevin Trenberth provides an interesting overview at The Conversation, detailing some of the weather extremes delivered by the current El Niño, and notes:

What we have seen this past year will likely be routine in about 15 years, although regionally the details will vary considerably. Indeed, we have had a glimpse of the future under global warming.

You wouldn’t want to bet against it continuing… Continue reading “Too hot (and here comes the surge)”
