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]
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]
Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
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 ...
The Planck response is the additional thermal radiation objects emit as they get warmer. Whether Planck response is a climate change feedback depends on the context. In climate science the Planck response can be treated as an intrinsic part of warming that is separate from radiative feedbacks and carbon cycle feedbacks.
The term nature-based solutions was put forward by practitioners in the late 2000s. At that time it was used by international organisations such as the International Union for Conservation of Nature and the World Bank in the context of finding new solutions to mitigate and adapt to climate change effects by working with natural ecosystems rather than relying purely on engineering interventions.
Geologic and biologic carbon sequestration of excess carbon dioxide in the atmosphere emitted by human activities. [1] Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere.
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 ...
