Earth’s atmosphere is in trouble. Scientists have linked rising temperatures in Earth’s atmosphere to carbon dioxide and other heat-trapping gases. When people burn coal or other fossil fuels, it releases carbon dioxide and other gasses into the air, causing the planet to heat up. Most scientists warn that conditions will get worse unless something is done soon. Among those trying to find a solution is a volunteer group of scientists and farmers in the United States. The group, called the Marin Carbon Project, says it has found a proven way to slow the rise in temperatures and possibly reverse it. John Wick and his wife own the Nicasio Native Grass Ranch in Marin County, California. He helped to set up the Marin Carbon Project. Wick says the project could help save the world from climate change.
