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 ...
The natural environment, commonly referred to simply as the environment, includes all living and non-living things occurring naturally on Earth.. The natural environment includes complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, soil, rocks, atmosphere and natural phenomena that occur within their ...
The environment is often cited as a negatively affected externality of the economy (see economic externality). extinction event - (mass extinction, extinction-level event, ELE) - a sharp decrease in the number of species in a relatively short period of time. extinction - the cessation of existence of a species or group of taxa, reducing ...
Climate sensitivity is a key measure in climate science and describes how much Earth's surface will warm for a doubling in the atmospheric carbon dioxide (CO 2) concentration. [ 1 ] [ 2 ] Its formal definition is: "The change in the surface temperature in response to a change in the atmospheric carbon dioxide (CO 2 ) concentration or other ...
Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment. [1] The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature ...
The ecological theory of alternative stable states describes how different ecosystems can exist side by side, and how they can shift as a result of disturbance. Applied to fire ecology, the theory describes how flammable and less-flammable vegetation types can exist side by side, and are maintained by different relationships with fire. [3]
In 1991, the journal's name was changed to the Annual Review of Energy and the Environment. This was done in recognition that energy research and issues were interconnected with environmental issues. [6] In 2003, the focus on the environment was further emphasized with an additional name change, to the Annual Review of Environment and Resources ...
The green line represents the base temperature of the burrow. Lizards are ectotherms and use behavioral adaptations to control their temperature. They regulate their behavior based on the temperature outside; if it is warm they will go outside up to a point and return to their burrow as necessary.
