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
