Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely. [220] Overall, it is expected that climate change will result in the extinction of many species. [221]
Positive climate change feedbacks amplify changes in the climate system, and can lead to destabilizing effects for the climate. [2] An increase in temperature from greenhouse gases leading to increased water vapor (which is itself a greenhouse gas) causing further warming is a positive feedback, but not a runaway effect, on Earth.

A change in the type, distribution and coverage of vegetation may occur given a change in the climate. Some changes in climate may result in increased precipitation and warmth, resulting in improved plant growth and the subsequent sequestration of airborne CO 2. Though an increase in CO 2 may benefit plants, some factors can diminish this increase.
A 2022 study suggests that the geologically recent conditions between 7,500 years ago and 2,000 years ago were already dry enough to cause substantial peat release from this area, and that these conditions are likely to recur in the near future under continued climate change. In this case, Cuvette Centrale would act as one of the tipping points ...
Drivers of climate change from 1850–1900 to 2010–2019. Future global warming potential for long lived drivers like carbon dioxide emissions is not represented. The scientific community has been investigating the causes of climate change for decades.
Loss and damage (in the context of climate change) is a concept to describe results from the adverse effects of climate change and how to deal with them (beyond climate change adaptation). [1] There has been slow progress on implementing mitigation and adaptation. Some losses and damages are already occurring, and further loss and damage is ...
The initial change that triggers a feedback may be externally forced, or may arise through the climate system's internal variability. [2]: 2222 External forcing refers to "a forcing agent outside the climate system causing a change in the climate system" [2]: 2229 that may push the climate system in the direction of warming or cooling.
Estimated median income loss or gain per person by 2050 due to climate change, compared to a scenario with no climate impacts (red colour indicates a loss, blue colour a gain). [1] An economic analysis of climate change uses economic tools and models to calculate the magnitude and distribution of damages caused by climate change.
