Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). Climate change may be limited to a specific region, or may occur across the whole Earth.

In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate. It may be qualified as anthropogenic climate change, more generally known as global warming.

• Crazy Iceland Scientists Drill Into Magma, Could Lead To Clean Energy Source
  Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland met with a big surprise: underground lava, also called magma, flowed into the well at 2.1 kilometers (6,900 feet) depth. It forced the scientists to stop drilling. “To...
• Iceland May Tap Liquid Magma as New Geothermal Energy Source
  Scientists in Iceland have been studying and utilizing the power of geothermal wells for years. In 2009 one such study hit a standstill when a group ran into magma halfway into their dig. The roadblock has become a blessing in disguise, and research has...
