Scientists at the US space agency Nasa estimated that the amount of energy released in the atmosphere above the Chelyabinsk region in the Ural Mountains was about 30 times greater than the force of the nuclear bomb dropped on Hiroshima during the second world war.

Perils of drought go beyond the US

The drought-stricken US Midwest seems far removed from the world's meal tables, but the interconnectedness to the global economy of the corn and soya beans it grows will be noticed in coming months. Prices will rise, particularly for meat, threatening inflation and social and political uncertainty.

Free as the air? In HK we pay through the nose to breathe

Elsewhere in the world people say the air is free. But not in Hong Kong. Here, if you want to breathe good-quality air, moderately free from pollution, then you have to pay for the privilege.

I'm not talking here about paying through the nose for a whiff of pure oxygen in an over-designed health 'bar', although you can do that if you want to.

Why fume now at U.S. over air data?

Beijing has finally let the cat out of the bag, admitting just how offended it has been by the release of air pollution readings by US diplomatic missions on the mainland.

The US embassy in Beijing and its consulates in Shanghai and Guangzhou must stop the 'irresponsible' practice of publishing their own real-time monitoring data online, mainland officials said this month.

Malls in air-con drive

More than 80 shopping malls will go green this summer by maintaining their indoor temperature at the recommended level of 24 to 26 degrees Celsius.

It comes after 88 malls, including Langham Place, Festival Walk and Cityplaza, signed an energy-saving agreement with the government. They will lower the use of air-conditioning between June and September this year.

New government must do more to clean up the city's polluted air

Air quality is still at dangerous levels most of the time in Hong Kong and may only improve during summer. Most pollution is locally generated.

I am worried about the PM2.5 level (fine particle concentrations) in Hong Kong.

Expect rainy days - but no more than usual

It's not raining more than usual in Hong Kong; it only feels like it sometimes, as the city gets pounded with increasingly intense downpours due to global warming, the Observatory said yesterday in presenting its annual forecasts.

This year will see normal - 2,300mm - to above-normal rainfall despite the heavier downpours, the weather service predicted.

Dragon arrives in a choking cloud

More than just festive spirits were running high as the mainland celebrated the Lunar New Year: the blaze of fireworks set off a spike in air pollution in major cities.

We've had enough of all this hot air

At long last, Hong Kong has new targets to aim for to improve air quality. They replace guidelines formulated 25 years ago and are closer to those recommended by the World Health Organisation in 2005. That they still fall short in several key areas and are the same as suggestions made after a public consultation in 2009 is disappointing, though.

Pollution set to stay

Hong Kong's dated clean-air targets will be toughened - for the first time in 25 years - starting in 2014, but green groups say they will still fall short of World Health Organisation standards.

The Executive Council on Tuesday endorsed 22 new air quality objectives first put out for public consultation in 2009.

No cause to breathe easier: experts

Hong Kong will still lag international standards even after it approves tougher air quality objectives, environmental groups say, while experts believe the city will struggle to meet some of the new targets.

Pollution brings capital to a crawl

Air quality in the nation's capital plunged yesterday morning to pre-Olympic levels again as dense smog blanketed the city, severely disrupting air and road traffic.

Pollution readings from both the local environmental watchdog and the US embassy exceeded the upper limit of 'hazardous' for most of the morning, prompting calls for urgent government action.
