<div>I think you are misstating the current status of global warming, and the impacts coming in the next few decades. The real problems have started. And children born today (not grandchildren or beyond) should expect to witness dramatic effects from global warming. Actually, right now, in the Arctic, they are. And relocation of the current generation on some low lying islands due to climate change impacts is already upon us:

<div><font face="Verdana" size="2">Details of the scheme were unveiled at a meeting organized by the United Nations Environment Programme's (UNEP) polar centre, GRID Arendal in Norway. <br><br>The meeting called 'Many Small Voices is building bridges between vulnerable Arctic communities and those of small island developing states.
<br><br>The meeting takes place today (6 December) during the 11th Conference of the Parties to the United Nations climate convention in Montreal, Canada. <br><br>Klaus Toepfer, UNEP's Executive Director, said: "The peoples of the Arctic and the small islands of this world face many of the same threats as a result of climbing global temperatures the most acute of which is the devastation of their entire ways of life".
</font><br>---------------------<br>Drowning or dying of heat prostration, as Paul wrote, due to human induced global warming, might already be happening for a few people (in 2003 a record heat wave killed many in Europe, and some think the full intensity of Hurricane Katrina, which drowned hundreds, was linked to global warming). But this hyperbolic language does not help the discussion. Most people on Earth are not at risk of this extreme consequence from global warming. Starvation (it's hard to avoid hyperbolic language) from climate related disruptions in food production would be a more likely consequence, in poor nations.
</div>
<div> </div>
<div>Shifting agriculture to northern latitudes that have warmed may offset some agricultural loses from climate change. But simple physics indicates that though they may be warmer, the solar energy in northern latitudes is less than closer to the equator, setting limits on total food production in these areas compared to their current locations for certain traditional staple crops. This might be addressed by genetic engineering of crops, suggested by the Stern Report as a measure to create drought or flood resistant plants, or engineering or substituting crops with a shorter growing season for northern latitudes.
</div>
<div> </div>
<div>One of the most certain effects of global warming will be ocean rise, which will remake the world's coastlines. Oceans will rise not only from melting ice but expansion from rising water temperature. But most everyone will relocate, not drown, we can assume? Certain low lying populated islands are already planning to relocate their populations. The economic costs of this world wide, though, are staggering, one variable that weakens the long term economic argument that the costs of lowering emissions are not worth the economic benefits.
</div>
<div> </div>
<div>As global warming's impacts are already dramatically impacting humans in the Arctic, with the lifestyle of the native peoples, their children's way of life, being disrupted tragically, the effects of global warming are accelerating, and within 50-70 years, much more severe effects will be much more widespread. The current climate trends in the Arctic are thus a warning to the whole planet, that should be heeded.
</div>
<div> </div>
<div>Children born today, even if we dramatically reduce emissions, will live to witness extreme effects from global warming (unless we extreme engineer our way out of the problem very quickly), just from the current carbon loading of the atmosphere, now at about 430 ppm CO2 (I have found conflicting figures, but all significantly above the 380 ppm figure from about a decade ago)
</div>
<div> </div>
<div>As has been pointed out over and over, poor nations, with limited resources to cope, will be hit the hardest. As the richest nation on Earth, most in the US may be able to maintain a "reasonable" standard of living, as global warming changes the planet, though I do not state this as a reason to continue our status as far and away the world's leader in per capita CO2 emissions. This is irresponsible in the extreme, as we indulge our wealthy lifestyle, jeopardizing the welfare of humans globally.
</div>
<div> </div>
<div>I think there is an understandable disbelief among many that the predictions regarding global warming are based on the sober estimates of a consensus of the world's climate scientists, who if anything are conservative in their work. The predictions are so incredible, it is reasonable to assume they must be from "alarmists" or "extremists" or those seeking financial or political gain from scare tactics.
</div>
<div> </div>
<div>However, though no doubt there are many interests, both financial and political, who will exploit global warming for their own ulterior purposes, an objective dispassionate assessment of the work of the world's climate scientists indicates we are facing a very serious crisis, with every decade of emissions based on business as usual increasing the severity of the problem.
</div>
<div> </div>
<div>Consider that every car on the Palouse emits 11450 lbs, and every light truck, 16035 lbs, of CO2, on average, annually. It disappears into "oblivion" yet it is changing the world's climate:</div>

<div>I would be pleased to discover the scientific consensus on the dangers of climate change to be mostly false, though It would be one of the greatest failures of the scientific community in history.</div>

<div>Stabilising gases at 450 ppm, seen likely as avoiding the most dangerous effects, was "already almost out of reach".</div>
<div> </div>
<div>The costs of extreme weather alone could be 0.5 to 1 percent of global Gross Domestic Product by 2050.</div>
<div> </div>
<div>Warming of 3 or 4C will result in many millions more people being flooded. By the middle of the century 200 million may be permanently displaced due to rising sea levels, heavier floods and drought.</div>

<div>Tim Flannery told Australian Broadcasting Corp. that an upcoming report by the U.N. Intergovernmental Panel on Climate Change will contain new data showing that the level of climate-changing gases in the atmosphere has already reached critical levels.
<br><br>Flannery is not a member of the IPCC, but said he based his comments on a thorough review of the technical data included in the panel's three working group reports published earlier this year.<br><br>Carola Traverso Saibante, spokeswoman for IPCC headquarters is in Geneva, said she was unable to disclose what would be in the final report synthesizing the data before it is released in November.
<br><br>"What the report establishes is that the amount of greenhouse gas in the atmosphere is already above the threshold that can potentially cause dangerous climate change," Flannery told the broadcaster late Monday. "We are already at great risk of dangerous climate change, that's what these figures say. It's not next year or next decade, it's now."

<div>In Germany, Chancellor Angela Merkel called Tuesday for an international system of global emissions trading to be adopted as part of an agreement to flight climate change from 2012 onward.<br><br>Speaking at a symposium of Nobel laureates and other leading scientists, Merkel insisted that only by establishing limits on carbon dioxide output per individual around the world--suggesting about 2 tons per head — could the fight to stop global warming be effective.
<br><br>"Our long-term goal can only be the assimilation of worldwide per capita emissions," Merkel told the conference.</div>
<div> </div>
<div>Flannery said that the recent economic boom in China and India has helped to accelerate the levels of carbon dioxide and other greenhouse gases in the atmosphere, but strong growth in the developed world has also exacerbated the problem.
<br><br>"It's a worldwide issue. We've had growing economies everywhere, we're still basing that economic activity on fossil fuels," he said. "The metabolism of that economy is now on a collision course clearly with the metabolism of our planet."
