There is at least one fact about Earth's climate that is not in dispute:  Increased levels of greenhouse gases cause the Earth to warm in response.  In addition, the U.S. Department of Energy estimates that humans are responsible each year for emitting nearly 6,000,000,000 metric tons of carbon dioxide, a common greenhouse gas generated by burning fossil fuels.

According to NASA, "Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities, and most of the leading scientific organizations worldwide have issued public statements endorsing this position."  The evidence is compelling - rising sea levels, global ocean and land temperature increase, shrinking ice sheets, more extreme events, and increased ocean acidification.

NASA is probably best known for it's incredible human and robotic exploration achievements - landing 12 astronauts on moon and sending unmanned spacecraft to farthest reaches of our solar system.  But did you know that NASA currently has more than a dozen Earth science spacecraft/instruments orbiting our home planet? The agency uses these satellites to research "solar activity, sea level rise, the temperature of the atmosphere and the oceans, the state of the ozone layer, air pollution, and changes in sea ice and land ice."

Global Climate Change is, by definition, a global phenomenon.  For this reason, observations from space provide an unparalleled vantage point to study and understand the entire Earth system.  NASA is uniquely qualified to carry out these observations, but it needs funding to continue doing so.

Let's help NASA continue to monitor the only planet we can call home.  Tell Congress that you support doubling funding for NASA: http://www.penny4nasa.org/take-action/
