Business as usual for Bush on Climate Change

One of the greatest difficulties for all of us in our attempts to tackle climate change is the lack of political leadership, especially from the largest polluters. While not the largest population the change of leadership in Australia will be good news in tackling climate pollution.

However while US president Bush has finally been acknowledging that climate change is a problem, events this week shows that the Bush Government intends to do nothing to reduce the Carbon-dioxide emissions from the US. Here in the UK, in the Financial Times, the leading business and financial publication, a conglomerate of international businesses, in a two-page advert, called for leadership in dealing with climate change. The response from the white house was simple, the US will not do anything to cap CO2 emissions and it, the bush government, can not even say when the US will be able to start reducing its carbon footprint.

The science and the evidence is so compelling now that, international business people realise that real action has to be taken. The difficulty is that unless the US, the largest economy in the world, takes political action and tackles climate change then business can’t plan for the investment in a low carbon future.

While there are some businesses that are making the effort, if we have a large economy like the US that refuses to impose regulation, then those businesses will loose money and or profits. Put simply the people that make the effort will always be undercut by the most polluting countries. In some ways this problem is similar to the way that manufacturing has chased the low wages in china. However, unlike this chasing of low wages, governments like the US allowing carbon pollution to occur will kill all industry.

The greatest problem is that oil men like Bush see climate change as an advantage as it is allowing access to the vast oil and gas deposits that are untapped in the artic circle. Further, the US Japan China and the EU are all looking to the probability of mining helium three on the moon, as a new wonder fuel. That is why there is a new moon race and why so many countries are rushing to land men on the moon again. The carbon footprint from these enterprises are vast and will mean that we will seriously damage our climate in trying to obtain this new fuel for an unproven technology.

Further, the US bush government; in particular, assume that the loss of the sea ice will not be that serious for the climate. However that is based upon a false assumption and reliant upon out of date science. In the last five years the unexpected acceleration in the melting of the sea ice has allowed the Greenland Ice cap to start melting. It is loosing up to 150 cubic kilometres of melt water per year. Further this is increasing and this water is flowing into the sea.

Also the Greenland Ice Cap is suffering from cracks and crevices opening up on the suffice of this vast glacier. This means that lakes of melt water that form in the summer are draining down to the bedrock where it is lubricating the flow of the Ice. But this melt water doesn’t re-freeze during the winter as just as happens in a pond or lake the ice on top insulates the water and stops it from freezing. All this is making the three kilometre thick glacier that is the Greenland Ice Cap very unstable.

It will not take a lot for this ice to break up. Scientists are monitoring the Ice and recording the vibrations of the cracking up of this glacier, known as Ice quakes, they occur every twenty minutes. There is an inevitability that sooner rather than later there will be a large area of this glacier will calf and slip into the sea. This will raise sea levels.

Further, any sizeable earthquake nearby could provide the trigger to allow very sizeable chunks of the Ice cap to slide into the sea. This could trigger Tidal waves as well as a sudden and substantial rise in sea levels. What makes this scenario even more disturbing is that the trigger is already in place. Mount St Helens in the US, an active volcano has a bulging plug in its calderas, and when that blows, the quakes and vibrations from that could well be all that it takes to see the glacier slip into the sea.

This is not something that will happen in some mythical time years hence, but within the next four to five years. I just hope that when it happens it finally shocks the US government into taking action on climate change.

I make a clear distinction here between the American people who want action taken on climate change and the Government who have their head in the sand.
