I want to call your attention to an article entitled "Humans Seem Hell Bent on Committing Mass Suicide -- But There's Still Hope". Here's just one paragraph:
What part of "for the first time in scientific history" do the global-warming deniers not understand?
The world’s scientists, traditionally competing for grants and laurels like the Nobel Prize, rarely agree. For the first time in scientific history, however, climate scientists have not only reached a near-unanimous consensus that human-made global warming threatens humanity, but have formed a global organization—the Intergovernmental Panel on Climate Change—to try and prevent it. Their most recent report states: "Warming of the climate system is unequivocal. Eleven of the last twelve years (1995-2006) rank among the twelve warmest years in the instrumental record of global surface temperature [since 1850]. ... [Climate change], together with sea level rise, are expected to have mostly adverse effects on natural and human systems [including] ... increased risk of deaths, injuries and infectious, respiratory and skin diseases ... water and food-borne diseases; posttraumatic stress disorders ... increased risk of deaths and injuries by drowning in floods; migration-related health effects."
