The world’s “top-rated” climate scientist implies that 437 degrees is on the way real soon.
The top-rated climate scientist in the world, James Hansen from NASA stated, “If we burn all reserves of oil, gas, and coal, there is a substantial chance we will initiate the run-away greenhouse. If we also burn the tar sands and tar shale, I believe the Venus Syndrome is a dead certainty.”
Venus has a temperature of 450°C (842°F), hot enough to melt lead. It once held water but the runaway greenhouse effect heated the planet so much that the water molecules were destroyed.
The sun’s energy hitting Earth is slightly more than half that of Venus. Burning the tar sands and tar shale could, over time, put Earth’s temperature to around 225°C (437°F).
