klímaérzékenységet

Klímaérzékenység, often translated as climate sensitivity, refers to the degree to which a climate system is affected by changes in climate forcings. This concept is central to understanding the Earth's response to factors like increased greenhouse gas concentrations. In simpler terms, it quantifies how much the global average temperature will rise in response to a doubling of atmospheric carbon dioxide concentrations. This hypothetical doubling is a standard benchmark used by scientists.

There are two main ways climate sensitivity is expressed. Equilibrium climate sensitivity (ECS) represents the eventual warming that occurs after the climate system has fully adjusted to a doubled CO2 concentration, which can take centuries. Transient climate sensitivity (TCS) measures the warming that occurs when CO2 levels have doubled, but the climate system is still in the process of adjusting. ECS is typically higher than TCS.

Estimating climate sensitivity involves complex climate models and observations of past climate changes. While there is a broad scientific consensus that the Earth's climate is sensitive to greenhouse gas increases, there is still some uncertainty in the precise value of climate sensitivity. This uncertainty is a key area of ongoing research in climate science. Understanding klímaérzékenység is crucial for projecting future climate change and informing mitigation and adaptation strategies.
