Nearly 200 countries overcome political divisions to agree on rules for implementing a landmark global climate deal, but critics say it is not ambitious enough to prevent the dangerous effects of global warming.

Half-way through talks to breathe life into the Paris climate deal negotiators haggle over how to share the cost of curbing global warming and struggle to bridge deep political divides.

In a new global index, Bangladesh has been ranked seventh among the countries most affected by extreme weather events in 20 years since 1998.

The UN secretary-general urges world leaders to join a climate change summit he will host in 2019 to explain how they plan to ratchet up their efforts to reverse worsening global warming that is leading to a "very dramatic situation".

British broadcaster and environmentalist David Attenborough urges world leaders, meeting in Poland to agree ways to limit global warming, to get on and tackle "our greatest threat in thousands of years".

Climate change is already hurting the global economy and will cost the US hundreds of billions of dollars annually by century's end unless drastic action is taken to cut carbon emissions, a major US government report warned on Friday.

International efforts to save some of the world's rarest and economically important plants from climate change are doomed to fail because their seeds cannot be stored, researchers warn.

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.
