Climate change Flashcards
Why does snowfall not disprove global warming?
Winter is a seasonal event; climate is long-term
What is the flaw in saying “CO₂ from breathing causes climate change”?
It’s part of a closed biological carbon cycle
Why is the Antarctic sea ice not a valid argument against global warming?
It distracts from the loss of land ice and Arctic sea ice
How do volcanoes compare to human activity in CO₂ output?
Human activities release significantly more CO₂ annually
What would a 5 to 10°C global temperature rise most likely cause?
A mass extinction event
What is ocean anoxia, and why is it dangerous?
Lack of oxygen in ocean water, threatening marine life
How does algae potentially help in recovering from climate disasters?
They sequester CO₂ through photosynthesis and burial
What impact could melting ice sheets have on New Brunswick?
Widespread inland flooding in cities like Fredericton
What does a temperature anomaly graph show?
Deviation from a baseline temperature
What key myth is disproven by the decrease in solar irradiance over the last 60 years?
