The Latest On: Black Carbon
Our homelands—the Arctic wildlife and ecosystems that are the foundation of our culture and traditional ways of life—are fast changing. Arctic warming has made the weather, the condition of the ice, and the behaviors and location of fish and wildlife so unpredictable that our Elders no longer feel confident teaching younger people traditional ways. If we cannot effectively pass on our traditional ways to the younger generations, we fear for what will happen to our culture.
Dr. James Hansen has never been shy about standing up for his scientific principles. In 1988, speaking before Congress, Dr. Hansen laid out a blunt truth, “It is time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here.” The statement caused an eruption of controversy, but time has borne out the sad truth of these words.
Last week, President Obama demanded that Congress take action on climate change, or else he would.
But, after years of political gridlock on the climate issue, coupled with rising seas and worsening droughts, one thing is clear: the nation simply cannot afford to wait any longer to take action. Though Congress may eventually pull together and pass a climate bill, the president must not wait on that uncertain prospect. He must act now.
As the environmental ministers of the Arctic nations, including the United States, meet in Sweden next week, they have an opportunity to show leadership on an important though less well-known climate pollutant, black carbon (soot).
While carbon dioxide remains the most important, long-lasting pollutant forcing climate change, recent studies have revealed that short-lived climate forcers like black carbon are equally damaging, especially in the Arctic.
