Question

speech Heating planet is sensible issue​

Answer 1

Answer:

The climate may be heating up less in response to greenhouse-gas emissions than was once thought. But that does not mean the problem is going awayOVER the past 15 years air temperatures at the Earth’s surface have been flat while greenhouse-gas emissions have continued to soar. The world added roughly 100 billion tonnes of carbon to the atmosphere between 2000 and 2010. That is about a quarter of all the CO₂ put there by humanity since 1750. And yet, as James Hansen, the head of NASA’s Goddard Institute for Space Studies, observes, “the five-year mean global temperature has been flat for a decade.”
