The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change.It is an international treaty among countries to combat "dangerous human interference with the climate system".
The Special Report on Global Warming of 1.5 °C (SR15) was published by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. [1] The report, approved in Incheon, South Korea, includes over 6,000 scientific references, and was prepared by 91 authors from 40 countries. [1]
Emission trajectories needed to achieve the Paris Agreement's two-degree target without negative emissions, depending on the emission peak. Evolution of land and sea temperatures 1880-2020 compared to the 1951-1980 average.
The Paris Agreement (also called the Paris Accords or Paris Climate Accords) is an international treaty on climate change that was signed in 2016. [3] The treaty covers climate change mitigation, adaptation, and finance.
The widespread adoption of a vegetarian diet could cut food-related greenhouse gas emissions by 63% by 2050. [110] China introduced new dietary guidelines in 2016 which aim to cut meat consumption by 50% and thereby reduce greenhouse gas emissions by 1 Gt per year by 2030. [ 111 ]
In order to stay under 1.5 °C of global warming, carbon dioxide (CO₂) emissions from G20 countries need to decline by about 45% by 2030 and attain net zero in 2050. [18] To be able to meet the 1.5 °C or even 2 °C, which is the maximum set by the Paris Agreement , greenhouse gas emissions must start to fall by 7.6% per year starting on 2020 ...
By 2050, the life cycle emissions of plastics could reach 56 billion tonnes, as much as 14 percent of the Earth's remaining carbon budget. [175] The report says that only solutions which involve a reduction in consumption can solve the problem, while others like biodegradable plastic, ocean cleanup, using renewable energy in plastic industry ...
A 2018 study examined the impact of climate change on Troglohyphantes cave spiders in the Alps and found that even the low-emission scenario RCP2.6 would reduce their habitat by ~45% by 2050, while the high emission scenario would reduce it by ~55% by 2050 and ~70% by 2070. The authors suggested that this may be sufficient to drive the most ...
