The threat to tropical rainforests from climate change may have been exaggerated by environmentalists, according to a new study.
Researchers have shown that the world’s tropical forests thrived in the far distant past when temperatures were 3 to 5C warmer than today.
They believe that a wetter, warmer future may actually boost plants and animals living the tropics.
The findings, published in the respected journal Science, come from a study of pollen trapped in rocks during a natural period of global warming 56.3million years ago.
The extreme warm spell – called the Paleocene-Eocene Thermal Maximum – saw global temperatures soar by 6C (11F) within a few thousand years.
