you write about warming as a key, if not primary, factor in the previous mass extinctions.
In the case of triggers such as asteroid hits and massive volcanic activity, there must have been significant initial effects from aerosols, resulting in loss of vegetation, etc. Certainly traditional TV science always shows the dinosaurs keelng over from starvation. :)
I understand that anoxia from warming was the primary cause of the loss of marine species, but was warming also the key factor on land? Is there a sense of how the two effects stack up in terms of proportions?
We all get behind sometimes. I look forward to reading more of your posts!
Kate, in your post on extinction and climate

As this is an open thread, i’ll use it as an opportunity to advertise the new climate science data visualisation app over at skeptical science:
