Evidence of Climate Change
What is an ice core?
A sample of ice from glaciers and ice sheets.
The ash and gas released from this natural phenomenon can have a cooling effect on the planet.
What are volcanic eruptions?
Animals no longer move at the same times or to the same locations.
What is changes in migration patterns?
What are humans?
These trap some radiation from the sun to warm the planet.
What are greenhouse gases?
What has increased since we started burning fossil fuels? (not greenhouse gases)
global temperature
This is the leading theory for what caused the dinosaurs to go extinct.
What is a massive meteor strike?
Drought has made these far more common in Alberta.
What are Wildfires?
This greenhouse gas is a major concern and many people/organizations are trying to reduce our emissions of this gas.
What is C02?
What is Methane?
Is a tool that emits a radio signal and allows meteorologists to detect precipitation, where it is, and how much is falling.
What is radar?
What is melting on the poles?
Ice caps.
What is the Greenhouse Effect?
The melting permafrost has particular impact on this group of people.
Who are the Inuit?
What are humans doing to increase CO2 emissions?
Factories, vehicles, and natural resource extraction (power, heat use).
Long-term patterns of weather that are what we expect for an area.
What is climate?
What's a sign of climate change? Early autumn or Early Spring?
Early spring
Methane, Carbon dioxide and water vapours are all examples.
What are Greenhouse Gases?
Weevils and leaf rust are examples of this threat to argiculture.
What are pests?
Wind, solar, tidal and hydro are examples.
What are renewable energy sources?
The loss of this means that less sunlight is reflected into space and it means that the planet will warm even faster.
What is melting sea ice?
How much did the sea levels rise since the industrial revolution? Between 1880 and now? (in cm)
21cm (21-24cm)
This natural phenomenon can cause the climate to change and the cycles are called Milankovitch Cycles.
What are changes to the Earth's orbit?
________ ___________ ___________ have resulted in hurricanes being more powerful, more common and starting earlier.
What is warmer ocean temperatures?
This is the one of the largest source of energy for electricity generation.
What is natural gas?
The name of the effect that shows how much sunlight is reflected back into space because the surface is white.
What is the albedo effect?
