What is the difference between climate change and climate variability ​
vaieri [72.5K]

Answer:

Climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then  certain weather events.

Explanation:

To explain more climate change is the change in the daily weather in a area for example rain forest to desert or cold to hot climate change goes along with global warming which is the heating of our Earth which causes ice to melt in the arctic rising our sea levels creating stronger storms. While in a climate variability its only a certain time of that specific climate change for example its only cold for a certain period of time then the temperature rises to hot again. So, the key difference is that "climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then  certain weather events."

Hope this helps!

Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapour evaporates into the atmosphere—which then amplifies greenhouse heating.
