d. 75

ANSWER: 75
 
On account of changing climate, Arctic regions of N.America are getting greener with a third of the total land cover looking more like landscapes found in warmer ecosystems, as per a new NASA study.
  • Close to 87,000 images taken from Landsat satellites has converted into data reflecting the amount of healthy vegetation in the Arctic and boreal N. America
  • Landsat is a programme providing continuous longest space based record of Earth’s land vegetation
  • It showcases the climate impact on vegetation at higher latitudes as well
  • Temperatures are warming faster in the Arctic than elsewhere which has led to longer seasons for plants to grow in and changes to the soils.
  • Climate impact on vegetation in the high latitudes has been the result of temperatures warming faster in the Arctic than elsewhere
