Can global warming cause wildfires?

Climate change has been a key factor in increasing the risk and extent of wildfires in the Western United States. Once a fire starts—more than 80 percent of U.S. wildfires are caused by people—warmer temperatures and drier conditions can help fires spread and make them harder to put out.

Floods are made more likely by the more extreme weather patterns caused by long-term global climate change. Change in land cover—such as removal of vegetation—and climate change increase flood risk.

How did the Sumerian civilization develop?

By the late 1990s, the scientific consensus was that it had stopped in the past and could do so again, possibly with disastrous consequences – albeit not overnight.
