For weeks, the world has been aware of a damning speech about global warming to be given by Al Gore at New York University’s law faculty today.
It has prompted the spin doctors to leak stories that George W Bush is about to announce sweeping green initiatives as a pre-emptive strike. They might have to go back to the drawing board:
Over to Al Gore:
A few days ago, scientists announced alarming new evidence of the rapid melting of the perennial ice of the north polar cap, continuing a trend of the past several years that now confronts us with the prospect that human activities, if unchecked in the next decade, could destroy one of the earth’s principle mechanisms for cooling itself.
Another group of scientists presented evidence that human activities are responsible for the dramatic warming of sea surface temperatures in the areas of the ocean where hurricanes form. A few weeks earlier, new information from yet another team showed dramatic increases in the burning of forests throughout the American West, a trend that has increased decade by decade, as warmer temperatures have dried out soils and vegetation.
All these findings come at the end of a summer with record breaking temperatures and the hottest 12 month period ever measured in the U.S., with persistent drought in vast areas of our country. Scientific American introduces the lead article in its special issue this month with the following sentence: “The debate on global warming is over.”
Many scientists are now warning that we are moving closer to several “tipping points” that could — within as little as 10 years — make it impossible for us to avoid irretrievable damage to the planet’s habitability for human civilization. In this regard, just a few weeks ago, another group of scientists reported on the unexpectedly rapid increases in the release of carbon and methane emissions from frozen tundra in Siberia, now beginning to thaw because of human caused increases in global temperature.
The scientists tell us that the tundra in danger of thawing contains an amount of additional global warming pollution that is equal to the total amount that is already in the earth’s atmosphere.
Similarly, earlier this year, yet another team of scientists reported that the previous twelve months saw 32 glacial earthquakes on Greenland between 4.6 and 5.1 on the Richter scale — a disturbing sign that a massive destabilization may now be underway deep within the second largest accumulation of ice on the planet, enough ice to raise sea level 20 feet worldwide if it broke up and slipped into the sea.
Each passing day brings yet more evidence that we are now facing a planetary emergency — a climate crisis that demands immediate action to sharply reduce carbon dioxide emissions worldwide in order to turn down the earth’s thermostat and avert catastrophe.
