Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
Adapting to climate change through efforts like flood control measures or drought-resistant crops partially reduces climate change risks, although some limits to adaptation have already been reached. Poorer communities are responsible for a small share of global emissions , yet have the least ability to adapt and are most vulnerable to climate ...
It is developed in phases to foster the climate model improvements but also to support national and international assessments of climate change. A related project is the Atmospheric Model Intercomparison Project (AMIP) for global coupled ocean-atmosphere general circulation models (GCMs).
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 ...
Climate action (or climate change action) refers to a range of activities, mechanisms, policy instruments, and so forth that aim at reducing the severity of human-induced climate change and its impacts. "More climate action" is a central demand of the climate movement. [1] Climate inaction is the absence of climate action.
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 ...
Attribution studies generally proceed in four steps: (1) measuring the magnitude and frequency of a given event based on observed data, (2) running computer models to compare with and verify observation data, (3) running the same models on a baseline "Earth" with no climate change, and (4) using statistics to analyze the differences between the ...
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Climate change may also refer to: Climate variability and change , changes in Earth's climate system resulting in new weather patterns that remain in place for an extended period of time
