What are the main effects of wildfires?
It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide—a key greenhouse gas—into the atmosphere.
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.

It is considered the most significant among the many cultural contributions of the Sumerians and the greatest among those of the Sumerian city of Uruk which advanced the writing of cuneiform c. 3200 BCE.
Can global warming cause floods?
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?

“It is safe to say that global warming will not lead to the onset of a new ice age,” two distinguished climate scientists wrote in the journal Science. 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.
