The benefits of basing policies on the 20-year GWP of HFCs

The steady growth in extreme weather events around the world signals that human-induced climate change is happening right now. In 2010 and 2011 we have witnessed unparalleled devastation around the world from record floods, fires, droughts, more frequent and intense tornadoes and hurricanes. In some countries, millions of acres of agricultural land have been lost due to flooding, while other countries report massive declines in crop harvests due to heat and drought. In China, up to 4 million people faced shortages of drinking water due to a drought along the Yangtze River, and portions of the river were closed to navigation. Currently, due to a prolonged drought, up to 10 million people face hunger and starvation in North East Africa.
