Sentences with phrase «similar warming events»

«We now have evidence from the Earth's history that a similar event happened fifty - five million years ago when a geological accident released into the air more than a terraton of gaseous carbon compounds... we have already put more than half this quantity of carbon gas into the air... and as a consequence the Earth is now returning to the hot state it was in before, millions of years ago, and as it warms, most living things will die.»
