HideShow resource information
What has caused the recent rapid rise in global temps?
Human activity - anthropogenic causes
1 of 7
What specific effect has this had?
Enhanced greenhouse effect
2 of 7
2 main GHGs?
co2 and methane
3 of 7
What is causing the rise in GHGs? (2)
1) Fossil fuels being burnt 2) Destruction of natural sinks (e.g deforestation)
4 of 7
What's causing the rise in methane? (3)
1) More fossil fuels being extracted 2) More decaying waste 3) More cattle (methane as waste)
5 of 7
What natural stores can give off methane
Melting permafrost - melting more with climate change (loop)
6 of 7
Limitations of models of future climate change (4)
1) Dont know how much GHGs will change 2) Change in atmospheric GHG conc. due to natural causes isn't known 3) Attempts to manage conc. and how successful? 4) Dont know effect of increasing GHG conc. due to complex feedback systems
