President Donald Trump is backing off his claim that climate change is a hoax but says he doesn’t know if it’s manmade and suggests that the climate will “change back again.”

Preventing an extra single degree of heat could make a life-or-death difference in the next few decades for multitudes of people and ecosystems on this fast-warming planet, an international panel of scientists reported Sunday. But they provide little hope the world will rise to the challenge.

More than three million people have been moved to safety in southern China as Typhoon Mangkhut moved northward and continued to wreak havoc across the region yesterday.

UN Secretary-General Antonio Guterres warns that the world is facing “a direct existential threat” and must rapidly shift from dependence on fossil fuels by 2020 to prevent “runaway climate change.”

Earth's intact forests shrank by an area larger than Austria every year from 2014 to 2016 at a 20 percent faster rate than during the previous decade, scientists says.

Prime Minister Sheikh Hasina has stressed the need for full implementation of the Paris Agreement as Bangladesh needs greater support for climate change adaptation.

A SpaceX rocket blasts off a duo of sports car-sized satellites built by the US and Germany to reveal changes in sea level rise, ice melt and drought on Earth.

Scientists in developing nations plan to step up research into dimming sunshine to curb climate change, hoping to judge if a man-made chemical sunshade would be less risky than a harmful rise in global temperatures.

Sea levels will rise between 0.7 and 1.2 meters (27-47 inches) in the next two centuries even if governments end the fossil fuel era as promised under the Paris climate agreement, scientists say.

The risk of extreme weather such as heat waves, floods and drought will rise significantly even if the commitments in the 2015 Paris climate accord are met, a study warns.

Sea level rise is accelerating and could reach 26 inches (66 centimeters) by century's end, in line with United Nations estimates and enough to cause significant problems for coastal cities, a study says.

Before man-made climate change kicked in -- and well before “Day Zero” in Cape Town, where taps may run dry in early May -- the global water crisis was upon us. Freshwater resources were already badly stressed before heat-trapping carbon emissions from fossil fuels began to warm Earth’s surface and affect rainfall.

President Donald Trump says that the United States could "conceivably" return to the Paris climate accord, although he stopped short of signalling any move in that direction.

Last year was the second hottest worldwide on record, just behind a sweltering 2016, with signs of climate change ranging from wildfires to a thaw of Arctic ice, a European Union monitoring centre says.

2017 has been the year of Climate Change impacts and its horrors making to the news on a daily basis. From hurricanes to wildfires, the previous year was a constant reminder that the planet is in the eye of the great climate change storm.

Prime Minister Sheikh Hasina leaves Dhaka for Paris on a three-day official visit to attend ‘One Planet Summit’.

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.
