Nhem En will be asked to testify against former Khmer Rouge bosses at their crimes-against-humanity trial in Cambodia. Nhem En had a unique job -- photographing the arrivals at Tuol Sleng prison in Phnom Penh, knowing they almost certainly wouldn't leave alive.

Air pollution in Beijing will not significantly improve before next year's Olympic Games, a United Nations report suggests.

In some cases, pollution is said to be more than three times the safe limits set by the World Health Organization.

The report seems to contradict claims from Beijing Olympic officials that air quality will not be a problem.

International Olympic Committee President Jacques Rogge said events may be postponed if pollution was too bad.

Global temperatures predicted for the coming centuries could trigger a mass extinction, UK scientists have warned.

The temperatures are within the range of greenhouse phases early in the Earth's history when up to 95% of plants and animals died out, they say. ...

They found that global diversity is high during cool (icehouse) periods and low during warm (greenhouse) phases.

"Our results provide the first clear evidence that global climate may explain substantial variation in the fossil record in a simple and consistent manner," said Dr Peter Mayhew of the University of York.

Atmospheric concentrations of carbon dioxide are rising faster than anticipated, finds a new study. Oh, and ocean absorption of CO2 is falling and sea levels are rising faster than expected.

Prominent Pakistani journalist Ahmed Rashid offers some thoughts on what the bomb attack on Benazir Bhutto and her followers means to democratic development and stability in Pakistan. The short answer? Nothing good. Nothing at all.

From the NYT blurb: A political meltdown in Pakistan, where Al Qaeda, the Taliban, and nuclear weapons are all in play, could be a disaster for the Bush administration.

How about the rest of us?

A quarter of China's greenhouse gas emissions are produced making goods exported to the West, a report from a UK government-funded body has found.

Climate research body the Tyndall Centre, using 2004 data, estimates the emissions are double those of Britain for the same period.

It wants rich nations to take the lead in cutting the pollution they cause.

In the last year, UK imports from China rose by 10%, nearing 6.5 million tonnes, according to a recent study.

Swiss voters go to the polls on Sunday after a general election campaign marred by riots and accusations of racism.

The right-wing Swiss People's Party (SVP), already the largest party in the parliament, is leading in the opinion polls and now expects at least 27% of the vote.

But the party's campaign has focussed almost entirely on immigrants.

Its controversial poster, showing three white sheep kicking a black sheep out of Switzerland, brought sharp criticism from the UN's special rapporteur on racism, Doudou Diene.

An even more graphic SVP video contrasts the "heaven" of a Switzerland in which trains run on time and families hike in the Alps, with the "hell" of veiled Muslim women, immigrant teenagers attacking Swiss girls and black men standing idly in the street.
