How can global warming affect where organisms can survive and reproduce?
It changes conditions in their habitats, altering where they can survive and reproduce.
How may species’ geographical ranges shift as the climate warms?
Towards cooler areas.
Changes in seasonal temperatures can alter the timing of which three biological events or resources?
Migration, breeding and food availability.
How can interacting species responding differently to global warming affect ecosystems?
Their relationships and food webs can be disrupted.
What three consequences can result when species lose suitable habitat or cannot respond to environmental change?
Population decline, reduced biodiversity and increased extinction risk.
Which two atmospheric gases are greenhouse gases?
Carbon dioxide and methane.
What do greenhouse gases do to infrared radiation emitted by Earth?
They absorb some of it and re-emit it, including towards the surface.
How does increasing atmospheric greenhouse gas concentration affect energy escaping to space?
It strengthens the greenhouse effect, reducing the rate at which energy escapes to space.
What parts of Earth warm over time as the greenhouse effect strengthens?
Earth’s surface and lower atmosphere.
What is global warming?
A long-term rise in average global temperature, not a temperature increase at every place and time.
