Sucking CO2 out of the air is vital to preventing climate change, UN warns | Daily
Technology that sucks carbon dioxide out of the atmosphere will be essential to prevent climate change, a UN report concludes today. Even a wholesale switch to renewable energy and everyone giving up driving and flying may no longer be enough to avoid a crisis. Global warming is already 1.1C above pre-industrial levels and scientists warn of irreversible harm if this exceeds 1.5C. The report, by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), says an urgent shift from fossil fuels is needed for any chance of keeping warming below this level.
