Australia's Great Barrier Reef is in peril from climate change and widespread bleaching, but scientists say a small portion may be resilient enough to keep much of the rest alive.

Carbon dioxide emissions are set to rise this year after a three-year pause, scientists say at UN climate talks, warning that "time is running out", even as White House officials use the occasion to champion the fossil fuels that drive global warming.

Climate change imperils one in four natural World Heritage sites, including coral reefs, glaciers, and wetlands -- nearly double the number from just three years ago, a report says.

The world must sharply draw down greenhouse gas emissions and suck billions of tonnes of carbon dioxide from the air if today's youth are to be spared climate cataclysm, a top scientist warns.

2017 is on track to be the hottest year on record except for two warmed by El Nino phenomena, the UN's World Meteorological Organization says.

The biggest problem for sustainable development in Bangladesh now is climate change, Water Resources Minister Anisul Islam Mahmud says.

Extreme weather caused some $129 billion (111 billion euros) in economic losses last year, says a report that warned the bill will keep climbing as climate change boosts droughts, storms and floods.

Sydney and Melbourne could regularly face 50 degree Celsius (122F) days within 25 years even if Australia meets its Paris global warming targets, a new study warns.

The United States has attended a meeting of ministers from more than 30 of the nations that signed the Paris climate-change agreement, though the White House issued a statement saying it will stick with plans to pull out of the deal.

Scientists say the devastating intensity of hurricanes such as Harvey is consistent with global warming trends -- rising seas, warming oceans, hotter air -- and warn of "bigger and stronger" storms to come.

Scientists freely acknowledge they don't know everything about how global warming affects hurricanes, but what they do know is enough to keep them up at night.

Venturing outdoors may become deadly across wide swaths of Bangladesh, India and Pakistan by the end of the century as climate change drives heat and humidity to new extremes, according to a new study.

Scientists are sucking carbon dioxide from the air with giant fans and preparing to release chemicals from a balloon to dim the sun's rays as part of a climate engineering push to cool the planet.

China, India, Indonesia and Vietnam have the world’s four biggest coal-fired power plants in pipeline. Together, they represent 82 percent of the 718 units globally under construction.
