I've been reading the summary of the Climate Change Report 2007 from the Intergovernmental Panel on Climate Change. Even without a science background, it's easy to see the profound impact human activity has, and will have, on the environment. By 2100 ocean levels are projected to rise between 7 and 23 inches and the average global climate may rise 3.5 to 8 degrees. Though the numbers themselves are small, they will have a substantial impact on the planet. What's more alarming than these projections are the consequences of climate change that are less known - how will changing air and water currents affect weather patterns? How will landform changes (new deserts, islands, coasts, etc) affect ecosystems? Food supply? Population distribution? The cities in which we live?
Maybe we (the U.S., specifically) can realize the error of our ways and become a leader and a role model to the world in cutting greenhouse emissions. Is it possible? What will it take?
