Polar Bears and Climate Change
Floods. Droughts. Heat waves. Massive storms. Climate change is not just about polar bears, the iconic symbol of a melting Arctic. It affects the entire planet. In fact, if our chief scientist, Dr. "Events like these will continue to increase in number and severity as the world continues to warm." What's causing climate change? What's causing climate change? Greenhouse gases (GHGs) in the atmosphere act like a blanket that keeps the earth warm. Other factors such as deforestation have added to the problem. Do scientists agree about climate change? The laws of physics dictate that the world will grow warmer and warmer as greenhouse gas concentrations rise. Are scientists still debating climate change? The important point to remember is that natural fluctuations in the climate system will continue with global warming, but the baseline will climb higher and higher. And once we cross those thresholds, it will be bad news not only for polar bears—but countless other species, including humans.
