World Has Missed Chance to Avoid Dangerous Global Warming

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 degrees Celsius, the aspirational limit adopted by the Paris Agreement on climate change.

Scientists: Carbon dioxide must be removed from the atmosphere to avoid extreme climate change

Humans must start removing carbon dioxide from the atmosphere as soon as possible to avoid saddling future generations with a choice between extreme climate change or spending hundreds of trillions of dollars to avoid it, according to new research.
