The power of film to reignite debate is demonstrated yet again.
Although the film is a huge exaggeration of the facts, climate change is happening and something has to be done about it.
According to current trends, weather will continue to get more extreme. Colder winters in Europe, drought in China and the possibility of more catastrophic weather disasters in the tropics could threaten the survival of humanity.
The Pentagon has commissioned an investigation to gauge the implications to national security of climate change and global warming. Climate change could case whole populations to have to mass-migrate or invade neigbours for resources. Austalia already has huge water problems due to drought but we can survive them (for the moment) because we are a well developed nation. However, Bush is still all but ignoring the problem.
Such measures as signing the Kyoto Protocal need to be takenby every nation to resist climate change. Controversial methods are being considered by scientisits around the world but none are without problems. Examples include harvesting carbon dioxide from emissions (expensive), increasing the use of nuclear power (hello terrorists), dropping emmisions drastically (there goes the world economy) and helping the 3rd world to become more efficient green house gas emitters.
A major problem is that the science is not perfect. We do not know for sure how much climate change is caused by human intervention. because we know little about how climate change works the genuine scientific debate actually makes it easier for governments to ignore the desperate pleas of the academics. Humanity has never been great on long term goals and sustainable development. The attitude of"It won't happen for centuries so who cares" is unfortunately held by powerful politicains and industrialists.
In Australia it is winter but a relatively warm one. The sea temperature is 20 C and the Antarctic wind is cool, as opposed to being bloody freezing in the relatively recent past. Such small samples of anecdotal evidence are all but useless. However, ice cores show that the temperature is rising steadily. Sub-Antarctic plant life is being replaced by more species which only grow in warmer climates. Likewise animal species are dying out for clearly climatic reasons. Evidence such as this cannot be ignored.
The solution is for scientists to develop fusion power and a way to efficiently take heat out of the atmosphere.
