  • Why is the climate of the Arctic so important?

  • But the climate of this unique and remote region can be both an early indicator of the climate of the rest of the Earth and a driver for weather patterns across the globe. William Chapman explains why scientists often describe the Arctic as the 鈥渃anary in the coal mine鈥?when it comes to climate change.

  • Is the Arctic the 鈥淐anary in the coal mine鈥?

Albedo in Latin means 鈥渨hite,鈥?and is a measure of how much solar energy is reflected back into space from a surface. Why is this so important in regard to climate change in the Arctic?

  • What happens when coal is extracted from the Earth?

In 2011, about 43% of the electricity in the U.S. was generated from burning coal.

  • Why did coal deposits wane during the Carboniferous period?

  • The scientists instead argue that the waxing and waning of coal deposits during the Carboniferous period was closely tied to a unique combination of tectonics and climate conditions that existed during the assembly of Pangea.
