This week US president George Bush has caused international outcry by reneging on the Kyoto agreement.
We ask: what do you think and what is to be done about it?
It was only a matter of time before the Toxic Texan started to make decisions solely in American interests. What can you expect from a man who has only been abroad once (to the country next door) and who is in the pay of the Texan oil barons? The Kyoto agreement must not be allowed to fail! It is now down to the rest of the industrialised world to take the lead and push ahead with change. The smallmindedness of the son of an oily father must not bring the world to its knees.

If Europe presses ahead with ratifying the treaty, as has been suggested, we will put our business at a disadvantage in the world market. This is probably the correct moral course, but will cost European jobs. Consequently, if we do ratify the treaty, we must actively and aggressively demonstrate to the world the damage that the US is doing by ignoring the treaty. We must turn the US into a pariah trading nation. Only in this way can we hope to offset the commercial disadvantage that unilateral ratification will bring.

Bush stated in his election campaign that he did not support Kyoto, so his aims have been clear for some time.
The US objects to the fact that developing countries, whose emissions are now approaching US levels, are not obliged to sign up to the protocol.
Although it pains me to say it, I think they have a point.
However, this is a global issue and whether or not the causal chain of global warming can be proved to be linked with carbon dioxide emissions, we will never know unless we start to reduce them. This means you too, Mr Bush. If he cannot be reasoned with, surely we can judge him to be an international terrorist and call in the SAS?

Impose trading tax penalties, and plough the income raised back into NASA, which in turn would speed up the Yanks' space station and Mars exploration development, meaning that they will all be living elsewhere in no time.
End of problem (for the time being anyway).
