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.
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.
