MIT predicts if we take no action, the planet will warm 5°C by 2100
Green Home Huddler —
The Massachusetts Institute of Technology Joint Program on the Science and Policy of Climate Change issued a report in January, “Probabilistic Forecast for 21st Century Climate Based on Uncertainties in Emissions (without Policy) and Climate Parameters” They conclude that if we take no action to reduce greenhouse gas emissions, "the median surface warming in 2091 to 2100 is 5.1°C...there is now a nine percent chance (about one in 11 odds) that the global average surface temperature would increase by more than 7°C (12.6°F) by the end of this century, compared with only ...
Revkin Beyond the Pale
Only In It For The Gold —
Revkin falls into his old habit of splitting the difference between lies and truth, and then offers some lame justification on his blog. This is not acceptable. Revkin should take a hint from Joe Romm on what the actual climate news is this week. I am also 100% behind Joe Romm on his take on Revkin's article. Just when you think Revkin is actually performing a service he comes up with this sort of poison. Revkin knows better. That being the case, this sacrifice of genuine balance for a cute but shallow sort of journalistic ...

... In short, as I have been arguing, the worst-case scenario is in fact now just business as usual -- a conclusion that both MIT and the Hadley Center agree with (see here and ...
U.S. media largely ignores latest warning from climate scientists: “Recent observations confirm … the worst-case IPCC scenario trajectories (or even worse) are being realised” — 1000 ppm

U.S. Media Largely Ignores Latest Warning From Climate Scientists
Worldchanging: Bright Green —
In the last two years, our scientific understanding of business-as-usual projections for global warming has changed dramatically (see " M.I.T. doubles its projection of global warming by 2100 to 5.1°C " and " ...
Michael Steele Helps Make "Sense" of Global Warming
DeSmogBlog - Clearing the PR Pollution that Clouds Climate Science —
... , have occurred throughout history. Therefore, while it is certainly not implausible that the planet may eventually lapse into another mini ice age, most projected trends point to several decades of warming, made worse by anthropogenic influences. Of course, if Steele understood this, then he’d already know why scientists are so concerned about the ...
China’s argument du jour for finishing off a livable climate
The Energy Collective —
... the primary obstacle to saving a livable climate for a long while now. And that has given cover to countries — most notably China — that also wanted to ramp up emissions unfettered by any restrictions or the world’s moral condemnation. No one expected China to build coal plants at a rate that would more than double their CO2 emissions in the past several years. But they have, putting the world on an emissions trajectory worse than even the most pessimistic IPCC scenario, one reason ...
Thinking Out of the Climate Box: Re-Examining Monolithic Approaches to the “Common But Differentiated Responsibilities” Impasse
The Green Leap Forward 绿跃进 —
... There is simply not enough time to be calculative and play the morality game. Emerging climate science is telling us that we may be in hotter soup already than we thought we were. MIT has doubled its 2100 projection for global warming to 5.1 degrees Celsius after taking into account non-linear feedback interactions. Separately, ...
High Odds of Hot Times
Dot Earth —
The Joint Program on the Science and Policy of Global Change at M.I.T. has published work, described earlier this year , that greatly elevates the odds of calamitous global warming should no significant action be taken to stem the buildup of greenhouse gases. The team ran a suite of 400 computer simulations incorporating both what is known about how the climate could react to a greenhouse-gas buildup and a wide range of variations in the global economy and other human factors that might affect the outcome. The results were boiled down to certain levels of odds for particular temperature changes, which the scientists and economists, led by Ronald ...
M.I.T. Doubles Its 2095 Warming Projection To 10°F — With 866 Ppm And Arctic Warming of 20°F
Worldchanging: Bright Green —
Today's question: How the heck does the Greenland ice sheet survive accelerated disintegration from projected 20°F warming by the 2090s? I previously blogged on how the Massachusetts Institute of Technology Joint Program on the Science and Policy of Climate Change has joined the climate realists — the growing group of scientists who understand that the business as usual emissions path leads to unmitigated catastrophe (see " ...
