World hopes to improve the Master Plan to keep warming to 1.5C
The best the Paris Agreement can do to control climate change is to keep the warming to 2.7C according to the international Climate Action Tracker. That is assuming every country meets their individual CO2 emission reduction target does and no natural feedbacks will speed the heating of the planet.
Other analysis find the Agreement will result in global temperatures rising to 3.0C or more. Even 2.7C is far too dangerous for humanity and most natural ecosystems we all depend on. Coral reefs will not survive scientists have warned.
Keeping warming below 2.0 will be more challenging – 1.5 even more so. This something humanity has yet to fully understand.
Here’s some things that will have to change:
* No more exploration for more oil, gas, coal
* The current $650 billion to $1 trillion/a year in fossil fuel subsides shift to alternative energy
* No new oil or gas wells, no new coal mines
* Sharply reduce the manufacture of anything that requires fossil fuel or convert them to run on renewable energy including cars and trucks, buildings, power plants and so on. See Study: Stop Building Carbon Infrastructure by 2018
That’s just for starters.
Climate science uses hard numbers. Those numbers say Fossil fuel use has to go to net zero sometime between 2060 and 2070. There is no negotiation.
