<div>I decided to check into worst case global warming scenarios, including the exploitation of methane hydrates for energy, which combined with traditional fossil fuels would release about 15000 Gigatons of carbon, most of it from methane hydrates, which store over twice the carbon of traditional fossil fuels:

<div>"If we follow business-as-usual then we will commit future generations to climate change, and if we exploit unconventional fossil fuels we could return the Earth to a hot state it has not seen since 55 million years ago," Dr. Lenton said.

<div><font size="4">Between 52 and 57 million years ago, the Earth was relatively warm. Tropical conditions actually extended all the way into the mid-latitudes (around northern Spain or the central United States for example), polar regions experienced temperate climates, and the difference in temperature between the equator and pole was much smaller than it is today. Indeed it was so warm that trees grew in both the Arctic and Antarctic, and alligators lived in Ellesmere Island at 78 degrees North.

<div>Trees in Antarctica! Alligators in Ellesmere Island (off the coast of Greenland)? What a great world future generations might live in!</div>

<div>That's the good news, because let's assume before this extreme state of affairs is reached, human beings will stop increasing CO2 levels via burning fossil fuels, and methane hydrates are a doubtful energy source, though commercial interests are investigating them.
</div>
<div> </div>
<div>Here's the bad news. This climate change model discussed below does not include methane hydrate burn, as far as I can tell, but just a continuation of what we are doing stretched out over the next three centuries burning traditional (oil, coal, natural gas) fossil fuels:

<p>LIVERMORE, Calif. — If humans continue to use fossil fuels in a business-as-usual manner for the next few centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar to
14.5 degrees warmer than current day:</p>

<div>For those who think modern urban cities are a bad idea, and wish a return to a more bucoli lifestyle for humanity, this scenario might fulfill their wish of phasing them out, because some urban areas on coastlines will be, shall I say, doing swimmingly!

<div>Maybe all the alligators flooded out of the Everglades in Florida can migrate to Ellesmere Island?</div>

<div>Nature and humans will adapt. Just ask George Bush.</div>
