2000s (decade) - Environment and Climate Change

Environment and Climate Change

Climate change and global warming became household words in the 2000s. Predictions tools made significant progress during the decade, UN-sponsored organisations such as the IPCC gained influence, and studies such as the Stern report influenced public support for paying the political and economic costs of countering climate change.

The global temperature kept growing during the decade. In December 2009, the World Meteorological Organization (WMO) announced that the 2000s may have been the warmest decade since records began in 1850, with four of the five warmest years since 1850 having occurred in this decade. The WMO's findings were later echoed by the NASA and the NOAA.

Major natural disasters became more frequent and helped change public opinion. One of the deadliest heat waves in human history happened during the 2000s, mostly in Europe, with the 2003 European heat wave killing 37,451 people over the summer months. In February 2009, a series of highly destructive bushfires started in Victoria, Australia, lasting into the next month. While the fires are believed to have been caused by arson, they were widely reported as having been fueled by an excessive heatwave that was due in part to climate change. It has also been alleged that climate change was a cause of increased storms intensity, notably in the case of Hurricane Katrina.
