Blown Away: 2015 Hottest Year by Far

January 13, 2016

Berkeley Earth is the first major global temp monitoring group to come out with a report on 2015 temps.  I repost group founder Richard Muller’s interview above – recounting his surprise at having his climate skepticism turned on its head, when he examined the data for himself.

Andrew Freedman in Mashable:

During the next week, the official climate agencies around the world that are responsible for tracking the planet’s average temperatures will almost certainly come to the same conclusion: 2015 was the warmest year on record. This would mean that 2015 would beat the previous warmest year, which occurred in 2014 — remember that?

The combination of a record strong El Niño event plus the highest amount of greenhouse gases in the atmosphere at any time in human history have given the climate system the equivalent of a Power Bar plus a shot of espresso. On Wednesday, one unofficial temperature tracking group, known as Berkeley Earth, revealed its determination that 2015 was by far the planet’s warmest year, both on land and sea.

There’s one especially important about fact about this group’s determination: It was set up in early 2010 as an independent fact check of other surface temperature data sets, and led by a physicist — Richard Muller — who had previously been quite skeptical of mainstream climate science findings. Instead of proving surface data from government agencies like NASA and the National Oceanic and Atmospheric Administration (NOAA) wrong, the Berkeley group has consistently reaffirmed their data.

The Berkeley Earth group said in a release on Wednesday that “2015 was unambiguously the hottest year on record.” More importantly, the group found that for the first time in recorded history, the Earth’s temperature is clearly more than 1 degree Celsius (1.8 degrees Fahrenheit) above the 1850-1900 average, and halfway to world leaders’ climate target of limiting global warming to under 2 degrees Celsius (3.6 degrees Fahrenheit) above average.

    A guy saving his butt as a scientist. I remember the time where he was trying to squeeze the hockey stick upside down. Well, at least he proportions his belief to the evidence now, and not the other way around as deniers still do.

    The second video here is one of your best, Peter. Donald Ducks everywhere is getting to be the norm, and I always enjoy seeing the Limbaughs, Inhofes, Becks, and Watts et al being exposed for what they are.

    I’m one that is always warning about “misleading graphs” and “making wishful thinking projections”, but the Berkeley Earth graph that Sir Charles posted has got me thinking. Considering this “hottest year” news and all the other recent news about things ;like arctic sea ice and tropical storms in both the Atlantic and Pacific in January, it’s hard to NOT “project” a 2016 that will change the slope of the red line in a decidedly unwelcome direction.

    Reason for that growing cold spot in the North Atlantic: Accelerating melt of Greenland’s ice sheets.

    Side effect: Rapid slow-down of the Atlantic draft (Golf stream).

    Worrisome!

  4. Sir Charles Says:

    => Study: Melting Greenland ice sheet is rapidly slowing the Gulf Stream
