2015 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.

It was signposted all year, but North American agencies have confirmed: 2015 was the hottest year since records began in 1880. NASA and the National Oceanic and Atmospheric Administration (NOAA) analysis showed that global surface air temperatures continued a long trend upward: 15 of the 16 warmest years on record have occurred since 2001. Globally-averaged temperatures in 2015 surpassed … Read More

Last year was the warmest year on record for the planet, analyses by NASA and NOAA show, and it’s possible that 2015 could be warmer still. 2014 was warmer than previous record holders 2005 and 2010, and comfortably ahead of 1998. 13 of the hottest 15 years on record have all occurred since 2000. Remarkably, […] … Read More

The NASA numbers are in, and 2011 was the ninth warmest year since 1880 — 0.51ºC above the 1951-80 global mean. Nine of the ten warmest years in the long term record have occurred in this century. According to the analysis released by James Hansen and his team at GISS, a combination of low solar [...] … Read More

‘Tis the silly season, time for journalists with little real news to report to reflect on the year past and make predictions for the year to come. I don’t normally play that game because there are too many interesting things to write about on the climate beat, but this year I’m going to make an [...] … Read More

A couple of weeks ago I plugged an upcoming talk by Pieter Tans of NOAA’s Earth Systems Research Lab in Boulder — a carbon cycle specialist and winner of the Roger Revelle Medal. The talk has now been and gone (on Wednesday in Wellington), and the Science Media Centre has made an audio recording available. [...] … Read More

An intriguing title for what promises to be an interesting seminar in Wellington later this month. Pieter Tans of NOAA’s Earth Systems Research Lab in Boulder — a carbon cycle specialist and winner of the Roger Revelle Medal at the 2010 Fall AGU — will be the guest of the NZ Climate Change Research Institute. [...] … Read More

Satellite images of New Zealand snapped right now looks rather impressive as parts of the country are layered in snow. UPDATE: Latest satellite images of New Zealand from NOAA are available here and a nice NASA image showing the weather pattern responsible for the snowfall is available here (H/T Sciblogger Chris McDowall and Scilbogs reader … Read More

Sunshine is pouring down on the Arctic, and the high summer melting season is well under way. This photograph from NASA’s Earth Observatory shows crew from the US Coast Guard cutter Healey collecting a supply drop canister from melt ponds on the surface of the ice in the Beaufort Sea during the current Icescape exercise.
