Sentences with phrase «extinction risks from climate change»

Current predictions of extinction risks from climate change vary widely depending on the specific assumptions and geographic and taxonomic focus of each study.

In its latest assessment of the progress of climate change, the body said: «If warming is not kept below two degrees centigrade, which will require the strongest mitigation efforts, and currently looks very unlikely to be achieved, the substantial global impacts will occur, such as species extinctions, and millions of people at risk from drought, hunger, flooding.»

These threats may possibly act in synergy to increase extinction risk from that seen in periods of rapid climate change in the past.

It presently is not possible to place exact probabilities on the added contribution of climate change to extinction, but the observations noted above indicate substantial risk that impacts from climate change could, within just a few decades, drop the populations in many species below sustainable levels, which in turn would commit the species to extinction.
