It's Worse Than We Thought, Update

I've warned that global warming is worse than they say.  Evidence for this has been found, and reported on here and here.
A major new study finds that “scientists may have hugely underestimated the extent of global warming because temperature readings from southern hemisphere seas were inaccurate.” In short, as New Scientist puts it, “it’s worse than we thought.”
and
global warming's effect on upper ocean temperatures between 1970 and 2004 has been underestimated by 24 to 58 percent
Most of the focus on global warming has been on atmospheric temperatures but the oceans are heating as well.  And now we find that the warming of the oceans has been underestimated.

It is worse then we thought, and even less is being done about it.

Alaska Crushes Record For Hottest December

Alaska crushes record for hottest December as Arctic sea ice hits record low In its hottest December ever recorded, Alaska was a stunning 15.7°F above the 20th century average. And the year ended with Arctic sea ice hitting an all-time record low. While the East Coast had a cool December and New Year’s week, Alaska baked. Last Tuesday, Anchorage hit 48°F , warmer than southern cities from Atlanta and Jacksonville to Houston and New Orleans. The National Oceanic and Atmospheric Administration (NOAA) reported this week that Alaska averaged 19.4°F for the month, topping the previous record (1985) by a whopping 2.1°F. “That’s really quite astonishing,” said Rick Thoman, the National Weather Service’s climate sciences and services manager for the Alaska region. As he explained to the Anchorage Daily News , “Usually you’re breaking those by a tenth of a degree or two-tenths of a degree.” The Arctic as a whole was so warm in December that Arctic sea ice set a new end-of-year record lo

The World My Grandchildren Will Inherit

I went to a presentation at the University of Washington by Professor Raftery of the Statistics and Sociology Departments of a recent paper of his and colleagues (Alec Zimmer, Dargan M.W. Frierson, Richard Startz, and Peiran Liu) in the Journal Nature, entitled Less than 2 °C warming by 2100 unlikely   (link behind a paywall) . Their paper is a response to a need to provide a statistical forecast for global temperatures.  What the IPCC has previously provided are "scenarios" based on "expert" thinking.  Raftery has previously developed statistical methods for estimating world-wide migration patterns that has been adopted by the United Nations.  At the presentation he presented a statistical model for forecasting global temperatures. Their result is a 90% interval forecast of 2 to 4.9 degrees Centigrade with a median of 3.2 degrees. Their backtesting strongly supported the median.  He also  said " that the data suggested that future improvements in ca
