Most Important Things You Can Do about Rapid Climate Change:

1. Understand the Problem
2. Do Something Today to Reduce Greenhouse Gas Emissions

This website will help you learn the connection between human-made Carbon Dioxide and rapid climate changes and negative effects around the world. The hard fact is that despite what many nations, companies, cities and people are starting to do to reduce their global warming emissions, the world is putting more CO2 into the air than ever before. The current amount is 385 parts per million (ppm) -- higher than ever in the past 800,000 years.

At the same time, renowned American climatologist Dr. James Hansen of NASA says we already have too much CO2 and other greenhouse gases in the air: "If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted ... CO2 will need to be reduced from its current 385 ppm to at most 350 ppm."

This is scary and controversial, but Dr. Hansen and others believe we must act fast-- as a world of concerned people and leaders taking every action we can to limit greenhouse emissions.350.org is a new movement of citizens from around the world which I recommend for its clarity of purpose and worthy goal.
