Also called global warming denial. climate change feedback A natural phenomenon that may increase or decrease the warming that eventually results from a change in radiative forcing. climate change mitigation approaches to limit global warming, primarily by the substitution of fossil fuels with low-carbon sources of energy climate commitment How much future warming is "committed", even if ...
A climate model is a representation of the physical, chemical and biological processes that affect the climate system. [172] Models include natural processes like changes in the Earth's orbit, historical changes in the Sun's activity, and volcanic forcing. [173]
Climate change affects livelihoods and living conditions in significant ways. These include access to natural resources and ecosystems, land and other assets. Access to basic infrastructure services such as water and sanitation, electricity, roads, telecommunications is another aspect of vulnerability of communities and livelihoods to climate ...
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect. As the geological record of ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
In the context of climate change mitigation, the IPCC defines a sink as "Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". [13]: 2249 Globally, the two most important carbon sinks are vegetation and the ocean. [120]
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the ...
