Scientists are warning us vehemently that we have to be net zero carbon by 2050, and we have to jump on getting there right now, or else very bad things will happen.
With pressure from the likes of Watson, a sleeping public may awaken to and act upon the imminent dangers of climate change.
We urgently need to view climate change not as a slow, linear process to which we can adapt safely over time, but as a nonlinear set of events involving dramatic and irreversible changes to the global ecosphere.
After re-examining data that seemed to show global warming slowing since 1998, U.S. scientists say temperatures have continued to rise steadily.
Trillions of dollars need to be redirected into building low-carbon economies to avoid serious climate change, the U.N. warns.
The destabilization of the climate will inflict "severe, widespread, and irreversible impacts" on humans and the natural world unless carbon emissions are cut sharply and rapidly, the most important assessment of global warming yet published says.
Far more heat than suspected is being absorbed by the oceans' top layer, scientists have found, but a study has uncovered little evidence of rising warmth at greater depths.
It looks unlikely to happen for a very long time, but German researchers say they have discovered how part of the East Antarctic ice sheet could start an inexorable melt.
The world should be moving to a clean energy future, the IPCC says. The recent record of global greenhouse emissions show it's heading in entirely the wrong direction.
