Focus on recent history misses the bigger picture. If the President and his Press Secretary look back before they were born, they will see a remarkably similar pattern of global warming. According to data from the Goddard Institute for Space Studies, temperature anomalies from around 1920 to around 1940 mimic those of the most recent two decades. Looking back even further, much of the last 10,000 years has seen a higher temperature as measured over Greenland than at our present time.
I don't dispute climate change is happening. In Alaska, I saw first-hand how much the glaciers have melted away. But the ice caps have been melting for nearly 12,000 years. Alaska used to be connected to Siberia by a 1200-mile wide land bridge, until covered by rising sea levels due to melting ice. The larger point is that humans are who we are because of climate change. And rather than the doom-and-gloom scenario some would paint for the future, William H. Calvin, professor at the University of Washington and author of A Brain For All Seasons: Human Evolution and Abrupt Climate Change, claims that temperature changes in the Quaternary period have resulted in "the longest-running rags-to-riches play in humanity's history."
Increasing evidence shows that climate change has been a significant driver of human evolution. Reports everywhere, from the Discovery Channel to the Royal Geographical Society and the National Academy of Science, have detailed how early human species evolved and spread out in response to rapid changes in the environment. Many animal species were driven to extinction by dramatic temperature swings. Humans survived primarily by becoming more intelligent and adaptable. Adaptability to those ever-changing conditions is what allowed us to survive, and to prosper.
Calvin also shows that the challenges of climate change forced humans to develop such traits as cooperation, hunting, and innovation. In a 2007 edition of Human Nature, Jessica Ash and Gordon G. Gallup, Jr. noted many of the new cultural technologies that arose to deal with the environment:
The problems of cold weather and a scarce food supply featured detailed and progressively more refined cognitive and intellectual strategies, such as the development of cooperative hunting techniques and more sophisticated tools and weapons. Increased brain capacity also brought with it the use of fire as a means to keep warm and cook, adaptations in clothing and shelter, and the development of more refined social skills.For years, organisations such as Greenpeace have argued that developing countries face the largest challenges in adapting to climate change. With weak economies and high population densities, they are the most vulnerable and face the gravest threats. According to Maria Athena D. Ronquillo, those countries "can only hope for leadership and early action" from the industrialized world. Such thinking makes them into victims. Early man did not hope for someone else to do something about the changes in his climate. He adapted, survived, and prospered. The trouble with the proposed Copenhagen agreements is, as Sarah Palin noted, drastic measures taken by alarmist environmentalists will dramatically change our economy, but won't change the weather.
We already have a model for Copenhagen. On 11 December 1997, the Kyoto Protocol was adapted as a draft treaty, and eventually adopted by 187 nations. The legally binding agreement mandated industrialized countries reduce greenhouse gas emissions by an average of 5.2% below 1990 levels. At the time, President Bill Clinton hailed the treaty as "environmentally strong" and said that "no nation is more committed to this effort than the United States." Congress never ratified the treaty, and far from reaching the proposed goal of a 7% reduction, the United States emissions have increased by 20%. Across the globe, carbon dioxide emissions have increased to a record 31.5 billion metric tons -- 38% above levels in 1990.
Reports from UNU-IAS, the United Nations' own strategic think tank, assert that it is the private sector which will play a significant role in developing responses to climate change. Technological innovation and market diffusion aren't produced by governments. Only in a free market will business investments in areas such as nanotechnology, ocean energy, or forestry spill over to other technology producers and users. Treaties coming from meetings like those in Copenhagen and Kyoto have been proven to fail.
During the last presidential campaign, Barak Obama promised change. Does he now propose to go back on his word, and try to stop climate change? Does he want to shut down the rags-to-riches play? Does he intend to halt or even reverse evolution? Why not let us have this change that has served humans so well for so long? I think we are all better now than we were 10,000 years ago. And there is a real scientific basis for that claim.
I'm a strong believer in robust climate change.
