Say what? They are our life blood and will continue to be for a long time. We can mitigate their negative effects, but we'd shrivel up and die without them. I thought I made my opinion clear in the past. It wouldn't be the first time that the thing that humans think they value most also has seriously negative consequences. In this case, my opinion is that the consequences could well be disastrous. I've already posted articles on why I think this and what those consequences could plausibly be. Google either "PETM" or "IETM" (or both) for the extreme possibility. But there is plenty between where we are now and there. Below is one projection. But of course, as Lomborg might say, the increased heat will be good for us, lol. Our Changing Climate Climatologists Forecast Completely New Climates September 1, 2007 — Geographers have projected temperature increases due to greenhouse gas emissions to reach a not-so-chilling conclusion: climate zones will shift and some climates will disappear completely by 2100. Tropical highlands and polar regions may be the first to disappear, and large swaths of the tropics and subtropics will reach even hotter temperatures. The study anticipates large climate changes worldwide. The eastern United States has a mild, humid, temperate climate, while the western United States has a dry climate, right? Well, according to climate models, global warming could change our current world climate zones, which would affect where crops are grown and even drive some plant and animal species to extinction, all in the next 100 years. Al Gore brought the issue to the big screen. Global warming -- what impact could it really have on our world? Geographer Jack Williams says, based on his new analyses of climate forecasting models, we're headed for major change -- fast. "One of the things that we can definitely say that the more carbon dioxide we put into the atmosphere, the models very clearly show more of a warming that takes place in the U.S. and worldwide," said Williams, of the University of Wisconsin. How much warming? With levels of CO2 continuing to rise, Williams suggests areas of the world that currently have a tropical climate will be much warmer and drive vegetation and animal life north. Williams believes these changes would lead to the spreading of Malaria northward, more catastrophic natural disasters and overall greater human health risks. "Even a few degrees Celsius can make a major difference in terms of where species grow and how well they thrive," Williams said. As North America came out of the last Ice Age, spruce trees moved northward. Williams said the same thing will happen, potentially driving plant and animal species into extinction if they can't adapt to the changes fast enough. "Species can migrate in response to climate change, but there's the question of how quickly can they migrate, and will these climate changes over the next century be so rapid that species will be unable to keep up," Williams said. Williams said that's why we need to take action now -- because later will be too late.

I thought I made my opinion clear in the past. Somehow people didn't just "shrivel up and die without them" in the past.

Yeah I know, I'm an extremist doom-and-gloomer.
