How Is Climate Change Affecting Our Ecosystem Flashcards
How much has the average global temperature increased since pre-industrial times?
The average global temperature has increased by about 1ºC since pre-industrial times.
What is the expected global temperature rise between 2030 and 2052?
The global temperature is expected to reach 1.5ºC between 2030 and 2052, leading to severe ecosystem impacts.
How much of global warming is absorbed by the oceans?
Over 80% of global warming is absorbed by the oceans.
What could happen to coral reefs with a 1.5ºC rise in temperature?
Up to 90% of coral reefs could disappear due to bleaching and ocean acidification.
What are the main causes of sea level rise?
Sea level rise is caused by the thermal expansion of water and the melting of glaciers.
How much has the average sea level risen since the late 19th century?
The average sea level has risen by about 20 cm (8 inches) since the late 19th century.
How is the rate of sea level rise expected to change in the future?
Sea level rise is happening faster than current projections, threatening coastal ecosystems and infrastructure.
How do climate change impacts affect weather patterns?
Increased evaporation leads to more intense rainfall and prolonged droughts, while extreme weather events, like hurricanes, are becoming more frequent and severe, especially in the North Atlantic.
How has the frequency of wildfires changed?
Wildfires are now five times more common, with longer fire seasons
What impact do wildfires have on ecosystems?
Burned ecosystems struggle to regenerate, causing long-term damage to biodiversity and habitats.
What is happening to glaciers worldwide?
Glaciers are rapidly melting, particularly in the Arctic.
Why are Arctic species like polar bears and narwhals vulnerable to climate change?
Arctic species face habitat loss and disruption to the food chain due to the rapid decline of ice and glaciers.
