Scientists say that if climate change is to survive, geoengineering is needed [UPDATED]



Editor’s Note 11/13/2020: Since we started this blog, experts have raised serious questions about its conclusions and methods. A climate scientist told Gizmodo, “This paper is nonsense and should not pass any competent peer review.” We will continue to monitor the dispute-and may update the story again.

long term planning

Even if we stop burning fossil fuels immediately, climate change will cause hundreds of years of damage to the planet.

That was the conclusion of the study published in the journal on Thursday. Scientific reports, It describes climate change and temperature rise as a vicious circle that has run out of control. result, Business insider According to the report, the European researchers behind the study said that without ambitious geoengineering projects to extract carbon from the atmosphere, it may be too late to stop global warming.

Vicious circle

The study authors said the problem is that carbon sinks like the Arctic tundra are releasing greenhouse gases, which heat the atmosphere and exacerbate climate change. The final result they calculated is that by 2500, the temperature will rise by 5.4 degrees Fahrenheit (3 degrees Celsius) and the sea level will rise by 8 feet.

Lead author and climate strategist Jørgen Randers said: “No matter how quickly humans reduce their greenhouse gas emissions, the tundra will continue to melt for the next 500 years. versus.

Clean up

Because their research shows that stopping carbon emissions is not enough to solve the problem, the researchers say that we need geoengineering technologies like carbon capture to control climate change.

“Because of its unexpected side effects, I usually oppose geoengineering,”

; Landers said. “However, if the world continues to delay meaningful and feasible actions to phase out fossil fuels, we may have to resort to geoengineering.”
