I guess we'll finally pay attention when Colorado goes underwater...

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

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 “Hadley Center projects 5-7°C warming by 2100“). Yet, much of the U.S. public — especially conservatives — remain in the dark about just how dire the situation is (see “Gallup poll shows catastrophic failure of media, conservatives still easily duped by deniers“).

Why? Because the U.S. media is largely ignoring the story. Case in point: Where was the coverage of the Copenhagen Climate Science Congress, attended by 2000 scientists, which concluded with this Key Message #1:
Recent observations confirm that, given high rates of observed emissions, the worst-case IPCC scenario trajectories (or even worse) are being realized. For many key parameters, the climate system is already moving beyond the patterns of natural variability within which our society and economy have developed and thrived. These parameters include global mean surface temperature, sea-level rise, ocean and ice sheet dynamics, ocean acidification, and extreme climatic events. There is a significant risk that many of the trends will accelerate, leading to an increasing risk of abrupt or irreversible climatic shifts.

The A1F1 scenario takes us to atmospheric concentrations of carbon dioxide of 1000 ppm in 2100 — otherwise known as the end of human civilization as we have known it. Actually it’s worse than that. The 2001 IPCC report largely failed to model amplifying carbon cycle feedbacks. The 2007 IPCC report, which began to consider such feedbacks, warns that even averaging 11 GtC (billion metric tons of carbon) a year this century could take us to 1000 ppm...
[my bold] ... why isn't this being screamed from the rooftops?

Just remember to buy your inflatable boat.

We're gonna have to plant lots of hemp to absorb all of that carbon dioxide. I don't think any other plant is faster at carbon biomass sequestration.

You can plant your hemp, Mahakal, and I'll plant my fruit trees with the attached squirrel-shooting automatic laser guns.

I haven't seen the studies on squirrel flatulence effects on global warming yet.

I'm going to get my PhD in squirrel flatulence.

Actually it's because the damned rodents bite my almost ripe apricots and throw them on the ground. Destroyed my crop last year.

I'm looking up depression era squirrel pie recipes...
