This claim to Antarctic land epitomises the government's lack of a coherent approach to tackling climate change.

In April, the British foreign secretary, Margaret Beckett, took climate change to the UN security council for the first time. Of major concern of the government, she said, were the expected "major changes to the world's physical landmass during this century," that would result from unabated climate change. It is a bitter irony, therefore, that it should now be that same British Foreign Office that is trying to profit from the melting ice of Antarctica and exploit precisely the changes to the world's landmasses that Beckett warned us about.

As the elections approach, Scotland is at an energy crossroads. Most Scottish people oppose new nuclear power. The Scottish National Party, Scottish Lib Dems and Scottish Greens all say no to new nuclear power. But Scottish Labour is toeing the Westminster line and refusing to rule out new nukes. Many in the party actively support nuclear plants in Scotland - with some suggesting that Scotland should be "pragmatic" about nuclear power because of climate change.

The UK will shortly become a net importer of gas, as the North Sea fields which have given us over 20 years of self-sufficiency finally begin to run dry; production is decreasing so that we are now a net importer, rather than a net exporter. The recent attempt by the Russian Government, Europe's major gas supplier, to hike the price of the gas it supplies to neighbouring Ukraine (the first step on the pipeline route to Western Europe) has led to intense media speculation over the security of supplies to the UK - in effect the argument is that since we cannot rely on a stable supply of gas, we should press ahead with a new generation of nuclear power plants which would guarantee energy security.
