Review: Scientists have "limited knowledge" of his climate change causes extinction

The report warns that scientists have “disturbingly limited knowledge” on the crucial issue, and that many species may become extinct long before their inability to cope physically with warmer conditions becomes a danger.

“This is arguably the most important topic in biology and the simple question of what actually causes a population to go extinct through climate change is completely understudied,” said John Wiens, an evolutionary ecologist at Stony Brook University in New York.

Understanding the precise ways that climate change impacted on different species was now “an urgent priority” for future research, he added.
