The latest bad news from IPCC

That is from the Intergovernmental Panel on Climate Change. It's a long article, but worth your time. And very sad too. Some highlights:

Humanity is rapidly turning the seas acid through the same pollution that causes global warming, the world's governments and top scientists agreed yesterday. The process – thought to be the most profound change in the chemistry of the oceans for 20 million years – is expected both to disrupt the entire web of life of the oceans and to make climate change worse.
[...]
[T]he report also predicts that nearly a third of the world's species could be driven to extinction as the world warms up, and that harvests will be cut dramatically across the world.
[...]
Scientists have found that the seas have already absorbed about half of all the carbon dioxide emitted by humanity since the start of the industrial revolution, a staggering 500 billion tons of it. This has so far helped slow global warming – which would have accelerated even faster if all this pollution had stayed in the atmosphere, already causing catastrophe – but at an increasingly severe cost.
[...]
A report by the Royal Society, Britain's premier scientific body, concludes that, as a result, of the pollution, the world's oceans are probably now more acidic that they have ever been in "hundreds of millennia", and that even if emissions stopped now, the waters would take "tens of thousands of years to return to normal".
[...]
It makes a host of specific predictions for every continent and warns that "impacts" could be "abrupt" or "irreversible". One example of an irreversible impact is an expected extinction of between 20 and 30 per cent of all the world's species of animals and plants even at relatively moderate levels of warming. If the climate heats further, it adds, extinctions could rise to 40 to 70 per cent of species.

And this is what saddened me the most, because I might never get to see it:

The Amazon rainforest will become dry savannah as rising temperatures and falling water levels kill the trees, stoke forest fires and kill off wildlife.

Will the world governments be able to agree on some kind of effective and decisive action?

Don't hold your breath for Bush jumping on the bandwagon...
