Tim Radford comments in the Guardian (3.8.2006) on proposals by Paul Crutzen to scatter sulphate particles in the upper atmosphere as a way of reducing global warming. Crutzen published his proposal in the August issue of Climatic Change. It's a good opportunity to get to know the new blog-like comment feature at the Guardian website Comment is free...but facts are sacred.
In an interview with Deutschlandfunk radio (2.8.2006) Crutzen responds to his critics. He says the most important point to combat global warming is reducing greenhouse gas emissions, especially CO2. But in politics almost nothing with relevance happens. He adds that his proposal is aiming at a principal investigation of sulphate particles in the stratosphere, side effects included.
