The Conversation: Inaction on climate change risks leaving future generations $530 trillion in debt

"The Paris Agreement in 2015 saw the international community agree to limit warming to within 2°C. The Hansen team argue that the much safer approach is to reduce atmospheric concentrations of CO₂ from the current annual average of more than 400ppm (parts per million) back to 1980s levels of 350ppm. This is a moderately more ambitious goal than the aspiration announced in Paris to further attempt to limit warming to no more than 1.5°C. Many climate scientists and policymakers believe that either the 2°C or 1.5°C limits will only be possible with negative emissions because the international community will be unable to make the required reductions in time.

Hansen, James; et al. (2017): Young people's burden. Requirement of negative CO2 emissions

Hansen, James; Sato, Makiko; Kharecha, Pushker; Schuckmann, Karina von; Beerling, David J.; Cao, Junji et al. (2017): Young people's burden. Requirement of negative CO2 emissions. In Earth Syst. Dynam. 8 (3), pp. 577–616. DOI: 10.5194/esd-8-577-2017

"Targets for limiting global warming thus, at minimum, should aim to avoid leaving global temperature at Eemian or higher levels for centuries. Such targets now require negative emissions, i.e., extraction of CO2 from the air. If phasedown of fossil fuel emissions begins soon, improved agricultural and forestry practices, including reforestation and steps to improve soil fertility and increase its carbon content, may provide much of the necessary CO2 extraction."

Daily Mail: Cutting emissions isn't enough: We must remove CO2 from the atmosphere as soon as possible to avoid extreme climate change, warn scientists

"Scientists say we must reduce the amount of CO2 in the atmosphere by 12.5%. Geoengineering measures could accomplish much of the needed CO2 removal. These could include replenishing forests or chemically altering the oceans. The researchers hope their study will push governments toward greener policies"

Simply Sustainable: Is Geoengineering the answer to climate change?

"Following the G20 Summit, French President Emmanuel Macron plans to host another climate summit in December and will again attempt to push Trump to join. Macron was quoted by the Washington Post as saying: “Our world has never been so divided.” His words couldn’t be truer: the USA stood alone on climate change, whereas the 19 other members agreed to push ahead with the Paris Accord to reduce greenhouse gas emissions."
