Could anybody recommend me some review paper on climate change or tell me some major names in that field? I work in a completely different area but I would like to learn about the current state of our knowledge regarding this subject. In particular I am interested in currently accepted forecasts, the human impact on the current trends etc..
Of course the most authoritative review paper is the IPCC report. You may find the latest report, the fifth revision, AR5, at the webpage: https://www.ipcc.ch/reports/ Depending on your background / time, you may like to first read the Synthesis Report and even Summary for Policy Makers. In the main report, consisting of many volumes, you may find technical explanation and references.
