Negative GHG emissions

If GHG emissions can’t be limited fast enough, technologies for backup plans are being developed. They range in two categories:

CO2 absorption from the atmosphere such as:
-Reforestation of deserts with limited watering.
-Growing plants, burning them to produce enough energy for capturing CO2 before injecting it in the ground.

Geoengineering for shielding the earth from solar energy such as:
-sulfur dioxide clouds or gigantic mirrors in the stratosphere.
-artificial vapor cloud creation.
These technologies are untested and may backfire with unexpected consequences. As temperatures keep climbing, some bet that geoengineering tech is a must!
