A related phenomenon driven by climate change is woody plant encroachment, affecting up to 500 million hectares globally. [231] Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [232] The size and speed of global warming is making abrupt changes in ecosystems more likely ...
As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [11] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [12] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [13]
The second part of the report, a contribution of working group II (WGII), was published on 28 February 2022. Entitled Climate Change 2022: Impacts, Adaptation & Vulnerability, the full report is 3675 pages, plus a 37-page summary for policymakers. [27] It contains information on the impacts of climate change on nature and human activity. [28]
Drivers of climate change from 1850–1900 to 2010–2019. Future global warming potential for long lived drivers like carbon dioxide emissions is not represented.. The scientific community has been investigating the causes of climate change for decades.
Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels.
This provides a picture of the varying contributions of different types of economic activity to climate change, and helps in understanding the changes required to mitigate climate change. Greenhouse gas emissions can be divided into those that arise from the combustion of fuels to produce energy, and those generated by other processes.
António Guterres, Secretary-General of the United Nations 28 February 2022 ~22 January: the International Monetary Fund stated that "Much larger coordinated global policies—including carbon price floors—will be needed to meet the new goals laid out at the (Nov 2021) Glasgow climate conference and stave off catastrophic global climate change.... Such national-level measures will need to be ...
In 2004, the geologist and historian of science Naomi Oreskes analyzed the abstracts of 928 scientific papers on "global climate change" published between 1993 and 2003. 75% had either explicitly expressed support for the scientific consensus on anthropogenic climate change, or had accepted it as a given and were focused on evaluating its ...
