Earth will face more Heat Waves: NASA
Scientists at NASA's Goddard Institute for Space Studies (GISS) warned that most of Earth's land areas might face an intense summer heat wave than what it faced between 1951 to 1980. NASA revealed that over the past 30 years the northern hemisphere has witnessed more "hot", "very hot" and "extremely hot" summers.
Earth’s northern hemisphere, which comprises of 90 % 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.
