Includes natural changes (cyclic variability, volcanic eruptions, solar output) and human-caused changes (due to GHG emissions and land use changes)

Concentration of carbon dioxide is about 1.4 times what it was before the Industrial Revolution. How much and how fast will Earth warm if carbon dioxide concentrations double the pre-industrial?

How do we know we can trust the historical surface temperature record? Did global warming stop in 1998? What actions can businesses or individuals take to reduce climate chagne from greenhouse gas emissions? Get asnwers to these and other frequently asked questions.

The most likely explanation for the lack of significant warming at the Earth’s surface in the past decade or so is that natural climate cycles caused shifts in ocean circulation patterns that moved some excess heat into the deep ocean.
