GLOBAL WARNING

Since the early 20th century, global air and sea surface temperature has increased about 0.8 degree Celsius (1.4 degree Fahrenheit), with about two-thirds of the increase occurring since 1980. Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850. Past 5 years has been recorded as the hottest years in history. For the year 2019 another 1.1 degree Celsius increase was recorded and 2020 has been declared as the second hottest year for our planet. Satellite data reveals that rate of glacier melting in the Himalayas has doubled in the past 20 years. This predicts that two-third of ice-cover in Himalayas will vanish by the year 2100.

In the last 25 yrs. increasing temperatures has melted around 6.4 trillion tonnes of ice in Iceland and Greenland. This has caused the sea levels to rise by 0.7 inches. Scientists believe that by the year 2100 ocean levels would rise by 6.6 inches swallowing maximum coastal areas across the globe. Also, researchers have issued a dire warning that in absence of dire actions entire ocean ecosystems would suddenly collapse by the end of next decade. Currently, this increase is in its alarming rate that is clearly giving us a Global WARNING.
