Consequences of the greenhouse effect on troposphere
Sea level rise due to thermal expansion
1 of 11
Consequences of the greenhouse effect on troposphere
simplified global circualtion of wind patterns, heat transfer will be effected, more heat more evap more rain
2 of 11
Consequences of the greenhouse effect on troposphere
El Nino and El Nina could occur more frequently
3 of 11
Consequences of the greenhouse effect on the north atlantic cconveyor
Global warming, Greenland ice sheet melts, Cold less salty water flows into north atlantic, changes desnity of the sea, changes direction of conveyor, crosses at the latitude of Spain.
4 of 11
Effects of the North atlantic converyor shifting
Northern Europe not warmed by currents, precipitation falls as snow, doesn't melt, glaciers build up, new ice age
5 of 11
Effects of greenhouse effect on life + example
Changes organisms, e.g. doormouse hibernation, warmer winters, use up more stored fat, starve before spring comes
6 of 11
Why is the greenhouse effect difficult to predict?
Some natural, some human, cant tell how much of each
7 of 11
Give a positive feedback mechanicsm.
Warming reduces cover of ice, less ice reduces albedo, more heat absrbed by ground therefore increase in infared given off
8 of 11
Give a positive feedback mechanism.
warming causes drying out, more forest fires, increase in co2 given off, contributes to ghg's
9 of 11
give a negative feedback mechanism
higher temperatures, increased rate of photosynthesis, more co2 taken in, reduces greenhouse effect
10 of 11
give a negative feedback mechanism
Warming produces higher amounts of evaporation, turns into low level cloud, increases albedo, reduces heating of earth surface
