Fra bloggen worldchanging.com – om amerikanske medier, men resultatene som ikke er så godt kjent der er neppe så godt kjent her heller…
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.
