Data from 2018 found that at 1.5 °C (2.7 °F), 2 °C (3.6 °F) and 3.2 °C (5.8 °F) of global warming, over half of climatically determined geographic range would be lost by 8%, 16%, and 44% of plant species. This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria. [41] [42]
It is considered likely that hitting 3.5 °C (6.3 °F) of global warming would trigger the collapse of rainforest to savannah over the course of around a century (50-200) years, although it occur at between 2 °C (3.6 °F) to 6 °C (11 °F) of warming. [76] [77] Forest fires in Indonesia have dramatically increased since 1997 as well. These ...
Heather Moonier, forest health monitoring coordinator with the N.C. Forest Service, said pine beetles aren't usually the cause of a tree's troubles, but are what's commonly called a secondary pest.
The rate of global tree cover loss has approximately doubled since 2001, to an annual loss approaching an area the size of Italy. [16] Amazon slash-and-burn agriculture, Colombia This section is an excerpt from Deforestation § Climate change .
Description and assessment of damage to tree structures (parts of a tree), to forest stands, landscape effects and to wood products, timber in service and other ecosystem services. Eradication of recently introduced pests, or long-term management of established exotics and indigenous pests, to minimise losses in wood quality and wood production ...
The extent of the impact depends on characteristics of both the pest and host tree. [10] Pests differ in their means of attack and extent of damage. For example, defoliating insect (spongy moth) may weaken trees but not directly cause mortality, while boring insects (emerald ash borer) can often cause serious damage.

Global warming projections indicate that surface air warming for a "high scenario" is 4 C, with a likely range of 2.4–6.4 C by 2100. [25] A temperature increase of this size would alter the biology and the ecology of many mosquito vectors and the dynamics of the diseases they transmit such as malaria.
