1
what is climate change mitigation
refers to the efforts to reduce or prevent the emission of greenhouse gases
2
increased co2 is warming the atmosphere. this then results in.... and a .... atmosphere. what type of feedback is this
higher evaporation rates and a wetter atmosphere. positive feedback- leads to further warming
3
what air temperatures when co2 concentrations rise, how does this affect the ocean
air temperatures rise, oceans then warm up and more vapour evaporates into the atmosphere, amplifies the greenhouse heating
4
explain how lag time affects climate change
the effects of co2 and global warming are delayed by approx 1 year. so when we see the effects we aren't seeing the immediate ones from the co2 going into the atmosphere now- co2 levels become the cause and effect of further warming
5
melting sea ice in the arctic may turn the area from a carbon sink to a carbon...
source
6
what type of feedback loop is marine phytoplankton and give a brief explanation why
negative. warmer temperatures---> increases in phytoplankton----> increase in clouds (as they produce DMS which may form condensation)---> global cooling
7
ocean surface water has become how much more acidic due to the increased absorption of co2
26% increase
