The Debate is Over, Except in Washington
The above image was produced in June 2005 to show regions of average lessened ice density due to melting (red) as well as regions where average ice was increasing due to increased precipitation (blue).
What the popularly elected but not Company in$talled 43rd President of the United States says:
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 twelve 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.
The serious debate over the climate crisis has now moved on to the question of how we can craft emergency solutions in order to avoid this catastrophic damage.
...Americans are tired of borrowing huge amounts of money from China to buy huge amounts of oil from the Persian Gulf to make huge amounts of pollution that destroys the planet's climate. Increasingly, Americans believe that we have to change every part of that pattern...
So, what would a responsible approach to the climate crisis look like if we had one in America?
Well, first of all, we should start by immediately freezing CO2 emissions and then beginning sharp reductions. Merely engaging in high-minded debates about theoretical future reductions while continuing to steadily increase emissions represents a self-delusional and reckless approach. In some ways, that approach is worse than doing nothing at all, because it lulls the gullible into thinking that something is actually being done when in fact it is not.
An immediate freeze has the virtue of being clear, simple, and easy to understand. It can attract support across partisan lines as a logical starting point for the more difficult work that lies ahead. I remember a quarter century ago when I was the author of a complex nuclear arms control plan to deal with the then rampant arms race between our country and the former Soviet Union. At the time, I was strongly opposed to the nuclear freeze movement, which I saw as simplistic and naive. But, 3/4 of the American people supported it - and as I look back on those years I see more clearly now that the outpouring of public support for that very simple and clear mandate changed the political landscape and made it possible for more detailed and sophisticated proposals to eventually be adopted.
When the politicians are paralyzed in the face of a great threat, our nation needs a popular movement, a rallying cry, a standard, a mandate that is broadly supported on a bipartisan basis.
A responsible approach to solving this crisis would also involve joining the rest of the global economy in playing by the rules of the world treaty that reduces global warming pollution by authorizing the trading of emissions within a global cap.
At present, the global system for carbon emissions trading is embodied in the Kyoto Treaty. It drives reductions in CO2 and helps many countries that are a part of the treaty to find the most efficient ways to meet their targets for reductions. It is true that not all countries are yet on track to meet their targets, but the first targets don't have to be met until 2008 and the largest and most important reductions typically take longer than the near term in any case...
Third, a responsible approach to solutions would avoid the mistake of trying to find a single magic "silver bullet" and recognize that the answer will involve what Bill McKibben has called "silver-buckshot" - numerous important solutions, all of which are hard, but no one of which is by itself the full answer for our problem.
One of the most productive approaches to the "multiple solutions" needed is a road-map designed by two Princeton professors, Rob Socolow and Steven Pacala, which breaks down the overall problem into more manageable parts. Socolow and Pacala have identified 15 or 20 building blocks (or "wedges") that can be used to solve our problem effectively - even if we only use 7 or 8 of them. I am among the many who have found this approach useful as a way to structure a discussion of the choices before us.
Over the next year, I intend to convene an ongoing broad-based discussion of solutions that will involve leaders from government, science, business, labor, agriculture, grass-roots activists, faith communities and others...
Read it all. Or watch it here. It's almost as important as keeping Dear Leader from launching global thermonuclear war.
