1. The scientific consensus remains solid
Suzanne Goldenberg in The Guardian has the story. A study led by John Cook of Skeptical Science fame considered the work of some 29,000 scientists published in 11,994 academic papers between 1991 and 2011.
Of the 4,000-plus papers that took a position on the causes of climate change only 0.7% or 83 of those thousands of academic articles, disputed the scientific consensus that climate change is the result of human activity, with the view of the remaining 2.2% unclear.
The survey found that the consensus has grown slowly over time, and reached about 98% in 2011.
The study authors tell their story at Skeptical Science and the Guardian’s new blog.
Of the papers which specifically examine the contributors to global warming, they virtually all conclude that humans are the dominant cause over the past 50 to 100 years.
