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 .
Global climate change will probably make it more complex and expensive to ensure water security. It creates new threats and adaptation challenges. This is because climate change leads to increased hydrological variability and extremes. Climate change has many impacts on the water cycle.
The Intergovernmental Panel on Climate Change says we have only around 12 years to reduce global carbon emissions to limit temperature rises to 1.5 degrees. While international and national actions are critical, at a local and personal level we need to play our role in achieving that target.” [ 189 ]
Climate change will lead to more very hot days and fewer very cold days. [39]: 7 There are fewer cold waves. [40]: 8 Experts can often attribute the intensity of individual heat waves to global warming. Some extreme events would have been nearly impossible without human influence on the climate system.
Average IPCC AR5 climate model projections for 2081–2100 relative to 1986–2005, under low and high emission scenarios. The Fifth Assessment Report (AR5) of the United Nations Intergovernmental Panel on Climate Change (IPCC) is the fifth in a series of such reports and was completed in 2014. [1]
Climate change is projected to negatively affect all four pillars of food security. It will affect how much food is available. It will also affect how easy food is to access through prices, food quality, and how stable the food system is. [170] Climate change is already affecting the productivity of wheat and other staples. [171] [172]
Al Gore and leader of IPCC Rajendra K. Pachauri on the balcony of Grand Hotel, Oslo, Norway, on 10 December 2007. The 2007 Nobel Peace Prize was shared, in two equal parts, between the Intergovernmental Panel on Climate Change (IPCC) (founded in 1988) and United States former vice president, Al Gore (b. 1948) "for their efforts to build up and disseminate greater knowledge about man-made ...
The National Climate Change Adaptation Strategy (NCCAS) has developed a framework for combating climate change. [57] Their framework includes five components which were assessed from 2011 to 2016: Mainstream climate-change adaptation into national planning and development; Enabling climate-resilient and healthy human settlements
