Scientists from the Intergovernmental Panel on Climate Change (IPCC) will reportedly be weighing up technology to remove carbon dioxide from the atmosphere, as they meet to finalize a major report that will be published on 4th April
The idea is among the several solutions that would be discussed over the next two weeks by the UN body. The meeting will also be graced by the attendance of government officials from across the globe for the approval of the summary report.
The latest study will be the final in the series of three key reports that IPCC had been issuing over the last eight months. The previous two looked at causes and impacts of climate change, and this one will be focusing on mitigation, or what can be done to stop climate change.
This means that researchers will be looking into reducing the number of warming gases emitted due to human activities.
Prof Jim Skea, IPCC co-chair, stated that the mitigation report will closely examine ways to remove the carbon already in the atmosphere.
Skea added that the report will be covering the full spectrum of carbon dioxide removal approaches, with the removed carbon dioxide likely ending up in different stores as well as in different places.
Various approaches to be considered would likely include agriculture and tree planting, along with more advanced technological approaches such as large machines for removing carbon from the air.
Combined approaches, such as using land to grow crops which can then be burned to generate energy, with the carbon it emits being captured and buried, would also be looked into.
Researchers will be working through each line of the summary with policymakers of 195 countries, with negotiations and agreements to follow for the final text.
The report will also focus on the overall social aspects of the supposed carbon removal efforts and short-term actions that can be taken by governments, before the end of this decade, in keeping the global temperature rise in this century below 1.5°C.
However, Prof Skea emphasized that the report will most importantly convey that humans can prevent climate change by taking immediate action.
