Lesson 10 Flashcards
Who are the IPCC?
Intergovernmental Panel on Climate Change
What do the IPCC do?
Reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change. It does not conduct any research nor does it monitor climate related data
Who monitors climate change in the UK?
living with Environmental Change Network (LWEC)
What effect does climate change have on the atmosphere? (3)
Increased anthropocentric green house has emissions
enhanced global warming
increase air and surface temperatures
How will climate change influence the hydrological cycle? (4) (precipitation)
increase convection and evaporation
Increased condensation and cloud cover
increased precipitation in low pressure regions (tropics and mid latitudes) Increased flood risk here
How will climate change influence the hydrological cycle? (3) (snow)
Decreased snow and permafrost and ice cover.
Increase in melt water will increase river flooding in next decades but then decrease after.
How will climate change influence the hydrological cycle?
3) (drought
Increase in high pressure systems.
Decrease in humidity and precipitation
Increase in severity of drought
How will climate change influence the hydrological cycle in urban areas?
Urban areas will see more flash flooding.
How will climate change influence the hydrological cycle (Rainfall)?
Annual rainfall may not change much but rainfall events will be more intense (heavy downpours).
How will climate change influence the hydrological cycle (flooding)? (3)
High flows and flooding are expected to increase over the century.
Estuaries will be at increasing risk from floods.
Sea level will rise by between 0.4 and 1m by 2100.
How will climate change influence the hydrological cycle (temperatures)? (4)
River water temperature will continue to increase.
Temperatures will increase across the UK, with greatest changes in summer.
River water quality may decrease because of higher water temperatures and increased sediments.
Increase in evaporation.
How will climate change influence the hydrological cycle (drought)?
Short droughts may become more frequent.
How will climate change influence the hydrological cycle (groundwater)?
There may be a decrease in recharge and lower groundwater levels.
How will climate change influence the hydrological cycle (species)?
Cold water species will decline, with increases in invasive species.
