Heat: 2014 breaks global temperature records, 2015 could be hotter - Hot Topic

Gareth Renowden Jan 18, 2015

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

Is earth’s temperature about to soar? (No pause, no hiatus, only warming) - Hot Topic

Gareth Renowden Dec 10, 2014

This is a guest post by the statistician who blogs as Tamino, cross-posted from his Open Mind blog with his permission. It’s important reading… A recent blog post on RealClimate by Stefan Rahmstorf shows that when it comes to recent claims of a “pause” or “hiatus,” or even a slowdown in global surface temperature, there […] … Read More

This year’s (super) model: visualising atmospheric CO2 - Hot Topic

Gareth Renowden Nov 20, 2014

Here’s a superb high resolution supercomputer visualisation from NASA’s Goddard Space Flight Center of the flows of CO2 in the atmosphere around the planet. Apart from being beautiful to look at, it shows the major sources of CO2 emissions in the northern hemisphere, and the seasonal change in CO2 levels as the northern hemisphere summer […] … Read More

TDB Today: WACCy weather and a warm year - Hot Topic

Gareth Renowden Jan 29, 2014

A classic case of WACCy weather in the northern hemisphere, seen here in a map from the excellent Climate Reanalyzer site, prompts me to discuss the 2013 global temperature numbers, the El Niño-Southern Oscillation, and what sea ice loss is doing to northern hemisphere weather patterns in my post at The Daily Blog this week. […] … Read More

Still warmin’ after all these years (Prat watch #5.6) - Hot Topic

Gareth Renowden Apr 30, 2012

Courtesy of Texas state climatologist John Nielsen-Gammon, a very nice graphical demonstration of why “warming” hasn’t stopped in the last decade (or two). Nielsen-Gammon took the GISS global temperature series, classified years as El Niño dominated, neutral, or La Niña, excluded the influence of the Pinatubo-cooled years in the early 90s, and then calculated the [...] … Read More

McLean’s folly 2: the reckoning - Hot Topic

Gareth Renowden Jan 12, 2012

Ten months ago, Aussie “sceptic” John McLean predicted that 2011 would be “the coolest year since 1956″. I pointed out at the time that this was nonsense, and so it has proven to be. I’ve taken the GISS global temperature figure for Jan – Nov 2011 (+0.51ºC compared to the 1951-80 average) and added it [...] … Read More

Jim Hansen to tour NZ: dates announced - Hot Topic

Gareth Renowden Apr 12, 2011

James Hansen will be touring New Zealand next month, giving a public lecture entitled “Climate Change: a scientific, moral and legal issue” in Auckland, Palmerston North, Wellington, Dunedin, Gore and Christchurch (schedule below the fold). Coal and lignite will be a major focus of his visit, and he’ll be participating in a symposium on “the [...] … Read More

Everyone agrees: 2010 ties for top temperature - Hot Topic

Gareth Renowden Jan 15, 2011

All of the major global temperature series — surface and satellite — report that 2010 is tied for first place as the warmest year in the long term record. NASA’s Goddard Institute for Space Studies and NOAA’s National Climatic Data Center both have 2010 tied with their previous record holder 2005, while the UK’s Climatic [...] … Read More
