Shared Socioeconomic Pathways ( SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. [ 2] They are used to derive greenhouse gas emissions scenarios with different climate policies. [ 3][ 4][ 5] The SSPs provide narratives describing ...
The public substantially underestimates the degree of scientific consensus that humans are causing climate change. [411] Studies from 2019 to 2021 [412] [4] [413] found scientific consensus to range from 98.7 to 100%. Climate change came to international public attention in the late 1980s. [414]
Air pollution, in the form of aerosols, affects the climate on a large scale. [ 46][ 47] Aerosols scatter and absorb solar radiation. From 1961 to 1990, a gradual reduction in the amount of sunlight reaching the Earth's surface was observed.
The United Nations' Intergovernmental Panel on Climate Change's (IPCC) Special Report on Climate Change and Land (SRCCL), also known as the "Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems", is a landmark study from 2019 by 107 experts from 52 countries.
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]
Deforestation and climate change. Deforestation in the tropics – given as the annual average between 2010 and 2014 – was responsible for 2.6 billion tonnes of CO 2 per year. That was 6.5% of global CO 2 emissions. Deforestation is a primary contributor to climate change, [ 1][ 2] and climate change affects the health of forests. [ 3]
Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. [14] IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere.
Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms. Taiwan ...
