An increase of 4°C 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

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

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°C of warming, sea levels could be rising by more than 1 meter, as the
world’s great coastal cities prepare for catastrophe.
