I do not understand the continual push-back on the issue of global warming, and I am fascinated and disturbed by how the question of our survival has become a partisan issue. I work in the medical research area and one characteristic of science is that there is often very little certainty, yet we move forward with the best knowledge we have available -- usually that which is accepted by the majority of scientists. There continue to be disputes about biomarkers and treatment of heart disease, for example, but we don't withhold treatment while we continue the research. To continue with the comparison, there may be questions about the causes -- the condition might be caused by "human activity" (or bad habits, in the case of the heart patient). The cause might also be genetic, or a combination of factors. Yet in each case we expect the patient to participate in their recovery, if they want to survive.
Our planet seems to be suffering from "inflammation", and its inhabitants will need to participate in its recovery, regardless of the cause. We can continue to argue about and research the causes, but as with heart disease, the longer we put off treatment, the less likely we are to recover.
There is more than enough evidence that our collective habits are at least part of the problem. It is almost certainly the cause of the increased acidity and growing dead-zones in the oceans, and the alarming number of species extinctions. That alone should be a wake-up call.
There has also been the argument that it would be unfair to our national interests if we take action, while developing countries balk. Yes indeed, China and India must be a part of the solution. But we can no longer afford to wait for others. We certainly weren't willing to wait for others when we went to war with Iraq. And (regardless of one's position on the war) I think it is fair to say we went to war with less certainty than we have about the threat of global climate change.
