NASA: Megadroughts Projected For American West

NASA: Megadroughts Projected For American West Droughts in the southwest and central plains of the united states in the second half of the 21st century could be drier and longer than anything humans have seen in those regions in the last 1,000 years, according to a new nasa study published in science advances on feb 12, 2015. Nasa scientists used tree rings to understand past droughts and climate models incorporating soil moisture data to estimate future drought risk in the 21st century.

NASA SVS | Instagram: Megadroughts Projected For American Southwest In a new study published in the journal science advances on february 12, 2015, scientists found that continued increases in manmade greenhouse gas emissions will drive up the risk of severe droughts. the study is based on projections from several climate models, including one sponsored by nasa. Analysis of current greenhouse gas emission trends indicate that the southwest and central plains have an 80% likelihood of megadroughts between the years 2050 and 2099. The study, published feb 12 in the journal science advances, is based on projections from several climate models, including one sponsored by nasa. the research found the risk of severe droughts in those regions would increase if human produced greenhouse gas emissions continue to increase. { "id": 11776, "url": "https://svs.gsfc.nasa.gov/11776/", "page type": "produced video", "title": "megadroughts projected for american west",.

During the past 1,200 years, four major megadroughts occurred in the american west: during the 800s, the mid 1100s, the 1200s, and the late 1500s. some evidence suggests these events upended. Nasa : megadroughts projected for american west (february 12, 2015). Climate models predict longer and more severe droughts by the end of the century. drought has stricken much of the u.s. southwest and central plains in recent years. but scientists now believe future droughts in the last half of this century could be the worst in the past millennium. Anthropogenic climate change has already contributed to recent megadroughts in southwestern north america and chile argentina and will likely increase future megadrought risk and severity in many regions.
