Summary
The effects of warming are also the manifest evidence that Earth’s climate is changing.
Causes, effects, and impacts reinforce one another through feedback effects that accelerate change, pushing us past crucial planetary-scale tipping points. Hence, several effects are included in the causes and impacts section of the Climate Wiki.
For example, as the planet warms, more snow and ice is lost. This reduces Earth’s albedo by exposing darker ocean and land, which in turn absorbs more heat, accelerating warming, so more ice is lost, and so on.
Not all bad weather is caused by climate change. ‘Event Attribution‘ tools can now determine how a warming world has increased the probability and intensity of a extreme events. Using recent events in Aotearoa as an example, the same extreme weather page explains the difference between extreme events and averages, and what a 1%AEP means.
