Climate Central's chief climatologist Heidi Cullen testified before the Senate committee on Environment and Public Works on the facts and impacts of climate change.
As Dr. Heidi Cullen reports, the suffocating heat comes on the heels of the government's release of the new climate "normals". Every 10 years, scientists from the National Oceanic and Atmospheric Administration calculate the 30-year averages for temperature and precipitation from thousands of U.S. locations.
What weÃ¢Â€Â™ve known as Ã¢Â€ÂœnormalsÃ¢Â€Â for our climate during the past decade will very likely change soon.
Some in Florida who lived through Katrina now are preparing for climate change-related disasters they fear could be more damaging than a hurricane.
Wildfires are on the rise in the State of Washington, as they are in much of the American WestÃ¢Â€Â”and climate change looks at least partly responsible. This report explores the connections between rising temperatures, melting snows, multiplying beetles and the increase in wildfires as well as the toll fires are taking on forests and the people who live in and around them.
A massive new billboard was installed in midtown Manhattan on June 18. It's a first-ever carbon counter that gives an up-to-the minute reading of greenhouse gases into the atmosphereÃ¢Â€Â”like a debt clock for the climate.
Coal generates carbon dioxide when combusted, which is causing the world to warm. In Georgia, a state that gets over 60 percent of its electricity from coal, some coastal residents are connecting the dots between coal and changes in the local ecology and economy attributed to global warming. Recognizing the need to reduce carbon dioxide emissions, engineers are exploring "clean coal" technology. What is this technology? Will it work?
Congress helped bolster the corn ethanol business in Iowa by mandating the Renewable Fuel Standard in 2005. But scientists are concerned about the unexpected consequences of putting more of Iowa's land into corn production Ã¢Â€Â” consequences that may make corn ethanol a bigger source of climate-warming gases than regular gasoline.
