The Tropics:
1. now a source of CO₂
2. ecosystem damage already huge
3. insects are vanishing
4. wildlife populations plummeting
5. forests at tipping point
6. marine life faces annihilation
7. most species face extinction
8. extreme heat soon to hit 4 billion

Carbon dioxide (CO2) emissions from tropical northern Africa much larger than previously thought, according to study using satellite observations in Nature Communications.
Results turn tropics as a whole into unexpected net source of this greenhouse gas.

The first high-level report on the state of all four of the world´s most diverse tropical ecosystems—tropical forests, savannas, lakes and rivers, and coral reefs:
'conclusions are bleak'.
'global biodiversity collapse is imminent' without urgent action.

Insects and other arthropods have declined by up to 99% over 4 decades in a Puerto Rican forest, apparently because of climate change.
Excessive heat can harm animals, especially those that have evolved to live in relatively constant tropical temperatures.sciencemag.org/news/2018/10/s…

Ongoing climate change is leading to an increase in frequency & magnitude of extreme climatic events in the tropics, which, in combination with other local human disturbances, is leading to unprecedented negative ecological consequences for forests & reefs

Catastrophic decline in animal populations the world over, with species population declines especially pronounced in the tropics.
🔺 South and Central America have suffered the most dramatic decline - an 89% loss compared to 1970.

Tropical forests are at/beyond a fragmentation tipping point. Global warming of 2C- 4C will destroy them.
67% of all species of plants & animals could be lost due to tropical deforestation alone.
Extreme warming scenarios: 55% of the species would be lost. Species in tropical regions are 2 - 4 times likelier to face extinction than those in temperate regions.edition.cnn.com/2020/02/21/wea…

Tropical species 6 times more sensitive to forests being broken up for logging or farming than temperate species.
Sensitivity to forest fragmentation increased six-fold at low versus high latitudes, putting tropical species at greater risk of extinction.eurekalert.org/pub_releases/2…

Absolute guarantee of corals' annihilation.
Domino effect:
"as reefs fail so will other ecosystems. This is the path of a mass extinction event, when most life, especially tropical marine life, goes extinct."

Disaster for nations with limited capacity to adapt to rapid climate change:
Tropical areas, which contain the richest diversity of species on the planet and some of the poorest countries, will be among the first to see the climate exceed historical limits.climatecentral.org/news/one-billi…
