Species migration due to warming
Species moving towards cooler areas, like the poles or higher elevations, to escape rising temperatures.
Species extinction from warming
Species extinction from warming
The loss of species due to inability to adapt or migrate to new areas, often due to human barriers.

Study Notes
Global Warming Impact on Plants and Animals
- Plants and animals are struggling to adapt to global warming
- Observed changes include earlier blooming of flowers and earlier bird hatchings
- Species are shifting locations and migration patterns in response to warmer temperatures
- Animals will move towards poles and higher elevations
- Plants will try to move to new, cooler habitats
- Human development often blocks these shifts, potentially leading to extinctions
- Species in unique ecosystems are vulnerable due to limited migration options
Projected Species Extinction
- Predicting extinction rates due to warming is challenging
- Some estimations suggest 20-50% species extinction with 2-3°C warming
- Some species and ecosystems may not adapt quickly enough
- Certain forests and other ecosystems face potential disappearance
Ocean Ecosystem Impacts
- Ocean ecosystems, especially coral reefs, are at risk
- Even 1°C warming can cause widespread coral bleaching and death
- Increased atmospheric carbon dioxide increases ocean acidity
- Acidification further stresses ocean ecosystems
