Here is the latest (draft) paper from James Hansen, the world’s best climate scientist.
In summary, the situation is much worse than you’re being led to believe.
We argue that global warming of 2°C, or even 1.5°C, is dangerous, because these levels are far above Holocene temperatures and even warmer than best estimates for the Eemian, when sea level reached 6-9 meters (20-30 feet) higher than today. Earth’s history shows that sea level adjusts to changes in global temperature. We conclude that eventual sea level rise of several meters could be locked in, if rapid emission reductions do not begin soon, and could occur within 50-150 years with the extraordinary climate forcing of continued “business-as-usual” fossil fuel emissions.
The 2 C goal set by our governments is not an appropriate goal because it is clearly dangerous, and despite this, we are almost certainly not going to achieve the goal.
It’s not like we tried and failed. We’ve done nothing except talk and deny the science.
Hansen laments here that even scientists are denying the science.
