Evidence of climate change includes:
\-Rising temperatures
\-Melting glaciers, ice sheets, and sea ice
\-Rising sea levels
\-Severe weather
\-Changes with precipitation patterns
\-Changes with seasons
\-Changes with ecosystems

New cards
Rising temperatures
\-Heat waves negatively affect humans and other species
\-Canada’s average increased 1.5C in the last 50 years, Yukon almost 2.5C
\-Causes forest fires

New cards
Melting glaciers, ice sheets, sea ice
\-The increasing temperatures cause the melting
\-Water shortages mean that the Earth depends on glaciers for fresh water
\-Melting ice means that less light is reflected and more heat is absorbed by the planet, because ice is white and melting ice means that the planet is getting darker, and dark things absorb heat

New cards
Rising sea levels
\-Sea levels are rising 2x as fast since 1933 than the previous 30 years
\-Rising sea levels causes floods in low altitude countries
\-Rising sea levels causes:
* Melting sea ice
* Thermal expansion (water expands as it warms)
* Decreasing ground water in North America

New cards
Severe weather
\-Heat waves and hurricanes become more intense/prevalent
\-Heat reduces farming opportunities which can lead to food shortages
\-Wildfires
\-Heat reduces farming opportunities which can lead to food shortages

New cards
Precipitation patterns
\-Heavier or less precipitation impacts agriculture
\-Less rain causes droughts, less farming opportunities, and food shortages
\-Heavy rains causes flooding, mud slides, and can destroy crops

New cards
Seasons
\-Different season lengths than normal (e.g. less frosty nights=warmer days) as a result of rising temps, melting ice, rising sea levels, severe weather and precipitation patterns
\-Can be harmful to other species like polar bears, because less sea ice means that they will have a food shortage

New cards
Ecosystems
\-Flowers bloom earlier in spring and animals breed earlier
\-Climate change provides opportunities for pests, diseases, and disease carriers to spread in new geographical areas (e.g. malaria)
\-Animals and plants migrating to poles (invasive species)
\-Loss of biodiversity (food web changes)
