Projected Change in Fire Weather Index in the Amazon Region (1950-2100)

Analysis by the NASA Earth Exchange of high-resolution climate projections concludes that, if global temperatures keep rising and reach 2 degrees above pre-industrial levels, people worldwide could face multiple impacts of climate change simultaneously, with serious consequences.

This map shows change in a measure called “fire weather index” (FWI) since 1950 and projected out to 2100 with respect to the baseline period of 1950-1979 (red: greater extreme fire weather; blue: less.) FWI captures a combination of conditions, including low rainfall and high winds, that together increase a region’s extreme fire weather condition. Analysis by the NASA Earth Exchange of high-resolution climate projections concludes that, if global temperatures keep rising and reach 2 degrees Celsius (about 3.6 degrees Fahrenheit) above pre-industrial levels, people worldwide could face multiple impacts of climate change simultaneously, with serious consequences.
