Global Warming, Climate Change, and Global Cooling are very complex issues which cannot be decided on by just citing a few studies. During the heating period in the 1930s and 1940s there were studies that stated global warming would benefit mankind while melting most Arctic ice by 1950. During the following cooling period up until the 1970s academic and doomsayers the American East Coast and most of Europe would freeze to death in the upcoming ice age. Recently scientists were predicting global warming would lead to super hurricanes; though now studies predict hurricanes will be weaker. Science, data, and models change. These studies probably were the best we could create at the time but we can do better now.
We all need to be rational while trying to create better models so there is less disagreement. Also we need to reasonably weigh countermeasures and pros and cons of any outcome. Going religious on the issue only harms science and the world. Case in point: British vandals were found not guilty damaging a power station because it was an act of self defense against global warming.
