A good, recent paper for biology on global warming would be "The Velocity of Climate Change" which discusses how far and how fast different species will need to move due to changes in environment caused by climate change
~ The reason there is a lot of political stuff about global warming is that the overwhelming majority of studies are either not focused directly on proving man-made climate change (for example, the study i refer to asks "what would the likely velocity be IF climate changes by X amount", it doesn't say that it has) or relies on simulating the climate system using computer models. This is essentially unfalsifiable - you either believe it or you don't.
Sadly, people like Paul B (below) who obviously do not read Nature or any other scientific journal, see fit to criticise those of us who do.
The paper i refer to is supportive of the theory of man-made global warming, but i offered it as a suggestion as i thought it would be most helpful to the asker of the question. I wasn't trying to push my own point of view, like Paul B does, just help someone.
For a review of global warming theory that is sceptical, peer-reviewed and written by a climate scientist, see http://www.friendsofscience.org/assets/documents/deFreitas.pdf
I guess it depends on how much you think computer models can model reality. After the credit crisis and housing market crash caused by computer models, i cetainly don't!
Hope this helped.
