Climate Change Flashcards
How can we tell the changes in climate?
Through looking at ice cores
Ice cores show…
Seasons, extreme weather events, how much CO2 was in the atmosphere
Colder periods are called…
Glacial periods
Warmer periods are called…
Inter-Glacial periods
What are cycles of climate called, which occur around every 100,000 years?
Milankovitch Cycles
What evidence is there for Climate Change (Name 4)
Instrumental records, rising sea levels (THERMAL EXPANSION), rising temperatures, ice cores, melting of glaciers, increase in frequency of extreme weather events.
Name 2 greenhouse gases
Methane, CO2, Nitrous oxide
Define sources of alternative energy
Hydroelectric, Solar, Wind, Tidal
Define afforestation
Growing more trees to take in CO2 (Carbon Sink)
Define International Agreements
Governments agreeing to monitor and reduce carbon production to mitigate climate change.
One example of International Agreements
2015 Paris Climate Agreement
Name 3 examples of adapting agriculture
Use rain water for harvesting, only watering plants when necessary, introduction of shade trees to protect saplings from intense sun (around equator), artificial trees created, vineyards being introduced in U.K.
Name 3 examples of changing water supply
Sewage and drainage volumes to increase in UK, increasing water storage for potential droughts, artificial glaciers created in Himalayas, more efficient showers and washing machines, use surplus water in areas lacking
Name 3 examples of reducing risk from rising sea levels
Introduction of flood proof houses, amphibious houses in the Netherlands, construction of sea walls, abandoning low lying areas such as Tuvalu and Pacific Islands, the entire Maldives population could be moved to India or Sri Lanka
