733097main1 Northern ndvi FINAL 673 NASA study shows rising temperatures and vegetation changes in northern hemisphere

A NASA-funded study of records of the last 30 years has shown that temperature changes in the northern hemisphere are leading to vegetation growth that resembles lusher climates south of the equator, another scientific confirmation of global warming.

A NASA-funded study of records of the last 30 years has shown that temperature changes in the northern hemisphere are leading to vegetation growth that resembles lusher climates south of the equator, another scientific confirmation of global warming.

 
An international team of researchers from universities and scientists from NASA examined changes in temperature and vegetation growth in the northern half of the planet, with results showing that northern latitudes now resemble the warmer environments 4 to 6 degrees further south.
 
“Higher northern latitudes are getting warmer, Arctic sea ice and the duration of snow cover are diminishing, the growing season is getting longer and plants are growing more,” said Ranga Myneni of Boston University's Department of Earth and Environment. “In the north's Arctic and boreal areas, the characteristics of the seasons are changing, leading to great disruptions for plants and related ecosystems.”

Satellite data from NOAA's Advanced Very High Resolution Radiometers and NASA's Moderate Resolution Imaging Spectroradiometer between 1982 and 2011 was analysed, revealing stark changes in the northern half of the planet over the last few decades.
 
“It's like Winnipeg, Manitoba, moving to Minneapolis-Saint Paul in only 30 years,” said co-author Compton Tucker of NASA's Goddard Space Flight Center in Greenbelt, Maryland.
 
Using 17 climate models the team were able to predict what might be in store for us in the future. They expect that increased temperatures in the Arctic and boreal regions will result in locations in the northern hemisphere having the climate of those 20 degrees further south by the end of this century, compared to data from 1951-1980. The findings were published in the Nature Climate Change journal.
 
In January NASA released a report highlighting the last decade as the warmest on record, with average temperatures rising by 1 degree Fahrenheit compared to a baseline temperature in the mid-20th Century. Combined with this latest study, there is a growing body of research supporting assertions of global warming.
