Climate Change Milestones
We have it hit 0.90°C (1.62°F) rise in average global temperature. This is enough to melt the polar caps, sink island nations beneath the waves, cause flash floods, cause heat waves, cause record hurricanes, cause record temperatures…
When it hits 1.7°C (3.1°F) the Great Barrier Coral Reef will die. We have already released sufficient CO₂ to hit this milestone, no matter what we do.
No matter what we do, we will hit 2.0°C (3.6°F) by the end of the century. This will be far, far more than twice as worse as what we have done so far.
If we carry on, business as usual, we will hit 4.0°C (7.2°F) by the end of the century.~ Roedy (1948-02-04 age:69)
