NASA’s Scientists warned Earth might face More Heat Waves

Scientists at NASA’s Goddard Institute for Space Studies ( GISS ) warned that most of Earth’s land areas might face an extreme summer heat wave than they did between 1951 to 1980. Scientists revealed that over the past 30 years the northern hemisphere has witnessed more “hot” ( orange ), “very hot” ( red ) and “extremely hot” ( brown ) summers.

Scientists noted that Earth’s northern hemisphere, which comprises of 90 percent of the planet’s land has become much more likely to experience an extreme summer heat wave compared to a base period from 1951 to 1980.

The researchers described how “extremely hot” summers has become a routine over the past 30 years. Since 2006, about 10 percent of land area across the Northern Hemisphere has experienced these temperatures each summer.

Study show how heat waves in Texas, Oklahoma and Mexico in 2011, and in the Middle East, Western Asia and Eastern Europe in 2010 fall into the new “extremely hot” category.
