Two years after a long-lasting undersea heat wave scalded large sections of the Great Barrier Reef, scientists have found that because so many corals died, much of the reef has probably been altered “forever.”

“What we just experienced is one hell of a natural selection event,” said Terry Hughes, director of the Australian Research Council Center of Excellence for Coral Reef Studies at James Cook University in Queensland. ...

(CNN)By the end of the century, the global temperature is likely to rise more than 2 degrees Celsius, or 3.6 degrees Fahrenheit.
 
This rise in temperature is the ominous conclusion reached by two different studies using entirely different methods published in the journal Nature Climate Change on Monday.
 
One study used statistical analysis to show that there is a 95% chance that Earth will warm more than 2 degrees at century's end, and a 1% chance that it's below 1.5 C.
"The likely range of global temperature increase is 2.0-4.9 [degree

HISTORIC HEAT Sea levels were 6 to 9 meters higher than present-day levels the last time Earth’s climate was this warm, new research suggests. Similar sea level rise today would submerge many coastal areas (red). JOHN C. KOSTELNICK (DATA), GSFC/NASA (VISUALIZATION)

The last time Earth's thermostat was cranked as high as it is today, sea levels were high enough to completely drown New Orleans (had it existed at the time), new research suggests. ... Read more about Here's what happened to sea levels the last time Earth was this warm
