2005 Hottest Year on Record

The temperature data for 2005 provide further evidence of what some scientists are calling a new geological epoch, the Anthropocene, in which human activities are the main driver of the global climate system. The amount that temperatures increase depends on what we do from now on to curb emissions of CO2 and other greenhouse gases. We can continue to use climate-disrupting fossil fuels or we can choose to shift to renewable energy sources and more-energy-efficient technologies.
