It is not a matter of a few years, but rather
of a few hundred years. |
Fortunately the sea can only rise another 100
yards, yet, that is a lot! |
|
|
As the globe warms up the slope of the
sea-level rise rate increases. |
Even if you go back 1,000,000 years the
"peak" temperature was not that high as it is now. The last peak 125,000
years ago was lower too. |

Measurements of CO2 started in Hawaii in the
1950's |
As the permafrost warms up (and the ocean
too) more CO2 will be released. The permafrost holds large amounts of
methane (another green-house gas).
Solubility of CO2 in the ocean decreases with higher
temp., just like in a can of Coke. |

Analyzing cylinders of ice -extracted by
drilling- from Antarctica, we can discover the CO2 level the air had (up to
about 600 million years ago). |
Small mammals have been on earth since 50
million years ago, but humans only 5 million years. We cannot breath an air
with more than 1000 ppm (parts per million). During Cambrian there were only
plants (basically), and fish during the Silurian and Devonian. |

The Globe flooded by about 60m, equiv. to 60
yards (about) |
The Globe flooded by about 100m, equiv. to
100 yards (about) |

It is not just Miami, most cities on the
eastern seaboard are at sea level. |
The Mississippi delta (especially New
Orleans) will soon be in trouble. |
