The planet is warming
at a pace not experienced within the past 1,000 years, at least, making it
“very unlikely” that the world will stay within a crucial temperature limit
agreed by nations just last year, according to Nasa’s top climate scientist.
This year has already
seen scorching heat around the world, with the average global temperature
peaking
at 1.38C above levels experienced in the 19th century, perilously

climate accord. July was
the warmest month since modern record keeping began in 1880, with each
month since October 2015 setting a new high mark for heat.
But Nasa said that records
of temperature that go back far further, taken via analysis of ice cores and
sediments, suggest that the warming of recent decades is out of step with any
period over the past millennium... Read more:
