Prominent climate researchers have warned that we must reduce the level of atmospheric carbon dioxide to 350 parts per million (ppm) or below in order to stabilize climate change and avoid global catastrophe. The Center for Biological Diversity, along with Bill McKibben's group 350.org, is advocating strongly for this necessary standard.
While carbon dioxide isn’t the only global warming pollutant we need to control, it’s the number-one contributor to climate change.
Several lines of evidence show that allowing atmospheric carbon dioxide levels to remain above 350 ppm for a sustained period of time will lead to dangerously acidic oceans, runaway global warming, and melting of the polar ice caps. Such a climate would be well outside anything experienced in the history of the human species, and would carry with it irreversible cascades of species extinctions and significant dangers for human civilization.
What's needed is an immediate reduction of atmospheric carbon dioxide, with the goal of an overall concentration of 350 ppm or less to be achieved as quickly as possible. To accomplish that, the Center supports the rapid phasing out of all coal-fired power plants, the highest technologically feasible vehicle-mileage standards, and a moratorium on Arctic oil and gas drilling, among other critical measures.
Please take one minute to join us in moving toward a real solution the climate crisis by calling on the EPA to do its job as science, the law and common sense require. Sign the People's Petition to Cap Carbon at 350 parts per million today. |
