Flashcards

Species Migration

The process of animals and plants relocating to cooler areas due to rising temperatures caused by global warming.

Migration Barriers

Areas where human development blocks the natural migration paths of species, leading to potential extinction.

Ocean Ecosystems

The delicate balance of life in the ocean that is particularly susceptible to changes in temperature and acidity caused by global warming.

Ocean Acidification

The process of oceans becoming more acidic due to increased absorption of carbon dioxide from the atmosphere, impacting marine life.

Study Notes

Impacts of Global Warming on Plants and Animals

Plants and animals struggle to adapt to global warming effects.
Shifts in life cycles are already observed, like earlier flower blooms and bird hatchings.
Species migration patterns are changing due to warming temperatures. Animals migrate to higher altitudes and toward the poles. Plants seek new ranges.
Human development often prevents species' shifts, creating barriers to migration. This can lead to extinction risks.
Unique ecosystems make species vulnerable as migration to new habitats is not possible.
Extinction projections due to warming are challenging.
Some estimate 20-50% species extinction risk after 2-3°C warming.
Some species and ecosystems cannot adapt quickly and may disappear.

Ocean Ecosystem Impacts

Ocean ecosystems are vulnerable to global warming.
Even a 1°C increase could lead to widespread coral bleaching and death.
Atmospheric carbon dioxide increases ocean acidity, stressing ocean ecosystems further.
