Knowra Climate change attribution Climate change attribution Climate change attribution assesses how human influences and natural factors contributed to observed changes in climate, including shifts in temperature, rainfall, and extremes.
Detection and attribution : A statistical framework for identifying whether climate has changed and estimating the causes of that change. This broader framework separates evidence that change occurred from evidence about its causes.
Radiative forcing : A change in Earth’s energy balance caused by factors such as greenhouse gases, aerosols, or solar variation. Forcing provides the physical link between causal influences and climate responses.
Extreme event attribution : The analysis of how human-caused climate change altered the likelihood or intensity of a specific weather event. It applies attribution methods to individual heatwaves, floods, droughts, and storms.
Climate change detection : The statistical assessment of whether observed climate changes exceed what natural variability can explain. Detection establishes that change occurred; attribution asks which factors caused it.
Climate fingerprint : A spatial or temporal pattern of climate change associated with a particular forcing or process. Distinctive fingerprints let researchers compare observed changes with expected human and natural signals.
Internal climate variability : Climate fluctuations arising from interactions within the climate system rather than external forcing. Internal variability can resemble or obscure the changes attribution seeks to explain.
Heatwave : A period of unusually high temperatures relative to the local climate and season. Observed heatwaves are among the clearest events for estimating the influence of human-caused warming.
Climate projection : A conditional simulation of future climate under specified assumptions about emissions and other influences. Projections explore possible futures, whereas attribution explains observed changes.
Detection time of emergence : The time when a climate-change signal becomes distinguishable from background variability. Signal emergence determines when attribution can reliably detect a forced change.
Climate observation : A measurement of a climate variable, such as temperature, precipitation, or sea level, collected over time. Attribution tests simulated causes against observed climate records.
