Reference document
It’s challenging to find unbiased resources on this topic. The latest Synthesis Report from Intergovernmental Panel on Climate Change (IPCC) is the best that I can find.
IPCC is a global effort;
the panel has been working continuously since 1988;
it is currently in its 7th assessment cycle.
