"So for those who are not sure what to believe, here is our round-up of the most common climate myths and misconceptions."

Is global warming now beyond debate? When does dissent become Untruth and lose the rights and respect due to "legitimate dissent"? Who decides

Great that he mentions algae! There are also algae based EPA supplements (not just DHA) - http://www.water4.net/

Those who are well off in Canada are far bigger eco-villains when it comes to harming the environment than those in lower-income groups, according to a study that is the first to try to quantify ecological damage done by Canadians based on income levels.

Winning the war on global warming requires slaughtering some of environmentalism's sacred cows. We can afford to ignore neither the carbon-free electricity supplied by nuclear energy nor the transformational potential of genetic engineering. We need to take advantage of the energy efficiencies offered by urban density. We must accept that the world's fastest-growing economies won't forgo a higher standard of living in the name of climate science

But I have been saying this for four years and I am boring myself. Of course we must demand that our governments scrap the rules which turn grain into the fastest food of all. But there is a bigger reason for global hunger, which is attracting less attention only because it has been there for longer. While 100m tonnes of food will be diverted this year to feed cars, 760m tonnes will be snatched from the mouths of humans to feed animals(9). This could cover the global food deficit 14 times. If you care about hunger, eat less meat.

The physical impacts of the global warming forecast can be bracketed with some degree of statistical confidence. Biological effects are more difficult to gauge, except in special cases such as the likely demise of polar bears that would result from the demise of Arctic sea ice. The societal effects, however, are nearly uncharted territory, at least to me. Perhaps the topic of global warming suffers from the same sort of cultural divide as university faculties, between the techies and the touchies; that is the sciences and the humanities. A new report (pdf) called The Age of Consequences, just released by the Center for Strategic and International Studies and the Center for a New American Security, tries to bring the social sciences, in particular history, geography, and political science, into the forecast of climate change in the coming century. It makes for fascinating if frightening reading.
