Fossil boffins say that dense triple-canopy rainforests, home among other things to gigantic one-tonne boa constrictors, flourished millions of years ago in temperatures 3-5°C warmer than those seen today - as hot as some of the more dire global-warming projections.
But now, according to further diggings, there is more evidence to support the idea that a proper rainforest similar to those now seen in the tropics existed at the time of the Titanoboa - despite the much hotter temperatures. This could be seen as conflicting with the idea that a rise of more than two or three degrees would kill off today's jungles with devastating consequences for the global ecosystem of which we are all part.
It's possible that the lush superwarm jungles of the globally-warmed future might be a bit less diverse than today's, however, as it seems that the old-time ones were.

they also forget data like in the OP here, the fact that the Climate has been shifting for billions of years without factories and human activity so the idea that all of a sudden after only 150 years of industry we've become a major climate factor is a little unrealistic.
