NASA Studies How Arctic Fires Change the World August 20, 2019 / activist360 / Leave a comment Wildfires in the Arctic often burn far away from population centers, but their impacts are felt around the globe. From field and laboratory work to airborne campaigns and satellites, NASA is studying how climate change is contributing to more frequent and powerful boreal forest and Arctic fires and what that means for climate forecasting, ecosystems and human health.
A Drier Future Sets the Stage for More Wildfires July 18, 2019 / activist360 / Leave a comment 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.
Using NASA Data to Monitor Drought and Food Insecurity July 9, 2019 / activist360 / Leave a comment NASA’s satellite imagery and model forecasts play an important role in monitoring the performance of crops worldwide and preparing for food shortages. NASA’s view from space helps government agencies forecast food insecurity, like during the drought in Southern Africa in 2018.
