Real Global Temperature Trend, p10 – Refining cloud feedbacks lifts climate sensitivity to 5-5.3 degrees(!), say Yale researchers

Climate models have falsely assumed a (strong) cloud brightening cooling feedback, researchers of Yale University (Ivy Tan & Trude Storelvmo) and the Lawrence Livermore National Laboratory (Mark Zelinka) write in Science. Refining cloud behaviour in a warming atmosphere leads to … Continue reading

Bird evolution faster than thought, but still 300x too slow to outlive present human-induced extinctions

Doesn’t the Tree of Life make for a beautiful infographic? Shown is bird evolution according to the Hackett backbone tree – one of two studied by the researchers. Using the world’s first family tree linking every known bird species, scientists … Continue reading

Climate skepticism and alarm rising over past decade according to survey

Researchers have found that between 2002 and 2010 the images and emotions that the American public associates with global warming shifted significantly.
