The University's Global Climate and Energy Project (GCEP) found that merely reducing emissions may not be enough for the US to hit its 17 % reduction in greenhouse gases by 2020 or to
avert dangerous levels of climate change globally.
One problem is that
dangerous levels of climate change are exacerbated by positive feedback loops — changes that release more greenhouse gases from nature due to warming driven by humans.
To avoid
dangerous levels of climate change, beyond 2C, the world can only emit a total of between 800 and 880 gigatonnes of carbon.
It would also make it more likely that other countries would back out of the deal or shirk their pledges, weakening an accord that already doesn't do enough to avoid
dangerous levels of climate change.
Why Europe needs three ambitious and binding targets for 2030 to cut greenhouse gas emissions, save energy and develop renewable energies to avoid
dangerous levels of climate change.
LONDON, 1 January, 2016 — Within days of the conclusion of the Paris Agreement at the UN talks in mid-December, two leading US scientists have cast serious doubt on its ability to avert
dangerous levels of climate change.
