A Drier Future Sets the Stage for More Wildfires

Droughts can create ideal conditions for wildfires. Dry trees and vegetation provide fuel. Low soil and air moisture make it easier for fires to spread quickly. In these conditions, a spark from lightning, electrical failures, human error or planned fires can quickly get out of control. As Earth’s climate warms and precipitation patterns change, increasingly severe droughts will leave some areas of the world vulnerable to increasingly severe fires. Understanding how fires behave in dry conditions can help firefighters, first responders and others prepare for a hotter, drier future.

2018 Was the Fourth Warmest Year on Record

2018 was the fourth hottest year on record. Earth has been warming up for decades. The last five years are the hottest five years on record and the last four were all more than 1 degree Celsius, warmer than the 19th Century average.

A warmer climate contributes to melting polar ice and mountain glaciers, rising sea levels, more severe droughts, longer fire seasons.

NASA and NOAA work together to study the temperature from weather stations, ships and buoys in the ocean, and Antarctic research stations.
