Our World Plus 4°C

°	An increase of 4 degrees Celsius causes the oceans to continue to rise, overtaking heavily populated deltas. Countries like Bangladesh and Egypt could be devastated, and cities like Venice could be totally submerged.
°	The Ganges River is the wellspring of life for over a billion people in China, Nepal and India. At first, the melting of Himalayan glaciers that feed the Ganges might unleash unprecedented floods. But then, extreme water scarcity and famine could strike if the glaciers vanish completely.
°	Studies suggest that at the current rate of loss, there will be no more glaciers in the Himalayas by the year 2035.
°	Northern Canada may become one the planet's most bountiful agricultural zones
°	The entire West Antarctic Ice Sheet could collapse, sending sea levels rising even further.
°	At 4 degrees of warming, sea levels could be rising by more than 1 meter, as the world's great coastal cities prepare for catastrophe.
