World powers are running out of time to slash their use of high-polluting fossil fuels and stay below agreed limits on global warming, a draft U.N. study to be approved this week shows.

Lots of fossil fuel has been burned over two decades as government officials and sundry others have sped across the globe to frequent United Nations-sponsored meetings aimed at tackling catastrophic climate change.

Scientists find global warming is slowed by eruptions of volcanoes

Volcanoes spewing sun-reflecting particles into the atmosphere have partly offset the effects of man's carbon emissions over a 15-year period that has become a global-warming battleground, researchers say.

British study says global warming will not be the end of killer winters

Global warming will fail to reduce high winter death rates as some officials have predicted because there will be more harmful weather extremes even as it gets less cold, a British study shows.

China treads cautiously in setting up carbon emissions trading

While mainland China is the world's biggest producer of carbon dioxide emissions, it has been relatively late in establishing exchanges to trade the pollutants. Photo: AP

China launched five regional carbon emissions exchanges last year, and two more are expected soon, but it is years away from having a mature trading platform.

Climate change caused by human use of fossil fuels played a role in about a half dozen extreme weather events last year, international scientists said on Thursday.

A team of experts examined 12 wild weather episodes last year, from droughts in the United States and Africa to heavy rainfall in Europe, Australia, China, Japan and New Zealand.

Carbon dioxide cuts cannot be solution to global warming

Tania Willis' letter ("Personal action now unavoidable to halt planet's destruction", June 1) quoted Al Gore and Jim Hansen in labelling carbon dioxide as the primary global warming pollutant. She has fallen short in showing why the 7.2 million people in Hong Kong must hold their breath because of the undesirable consequences claimed by her.

US President Barack Obama is preparing regulations to limit carbon dioxide emissions from existing power plants, senior officials said, in a significant move towards addressing global warming.

But the policy is sure to provoke legal challenges from Republicans and some industries.

US scientists warn about New York flood threat

By the 2050s, more than 800,000 New York residents could be living in a flood zone that would cover a quarter of the city's land. Not only that, but New Yorkers could sweat out as many 32-Celsius days as is now normal for Alabama in the US' Deep South as effects of global warming take hold, a scientists' group convened by the city says.

Alex Lo's column scolding the millions around the world who marched against Monsanto and its genetically modified crops ("Time to modify our stance on GM food", May 28) misses the point entirely.

On May 10, on his blog Al's Journal, former US vice-president Al Gore wrote, "Yesterday, for the first time in human history, concentrations of carbon dioxide, the primary global warming pollutant, hit 400 parts per million in our planet's atmosphere."

Tokyo bolsters defences for storms that would dwarf Hurricane Sandy

If Tokyo's Arakawa River breaks its banks in a storm, about 2,000 people are likely to be killed and 860,000 would be stranded, the government says. Photo: Bloomberg

Tokyo, the world's most populated city, is building defences for a once-in-200-years flood that could dwarf the damage Hurricane Sandy wrought on the US east coast.
