Some scientists now urge thta geoengineering is essential, to save the climate

Independent 21st Aug 2017, The world has missed the chance to avoid dangerous global warming – unless
we start geo-engineering the atmosphere by removing greenhouse gases,
according to new research. Scientists used computer models to assess what
needs to be done to restrict global warming to between 1.5 and 2 degrees
Celsius, the limits adopted by the Paris Agreement on climate change.

They found that the world was likely to overshoot this temperature but could
bring it back down to 1.2C by the end of this century by using techniques
to remove carbon dioxide from the air.
