Water Cycle And Water Insecurity- Climate Change Flashcards
Who predicts that there will be shifts in the hydrological cycle due to GHG?
The IPCC
Intergovernmental panel on climate change
What does increasing anthropogenic green house gas emissions lead to?
Increasing heat trapped in the atmosphere (enhanced global warming)
What does the enhanced global warming lead to?
Increasing average air temperatures and sea ice surface temperatures
How is the cryosphere affected by increased air temperatures and sea ice surface temperatures?
Decreased snow, permafrost and ice cover
Initial increase in meltwater will increase river floods during the next decades but decrease there after
How does anthropogenic gas emissions lead to increased risk of floods in certain areas?
Increased convection and evaporation
Increased condensation and cloud cover
Increased precipitation in low pressure regions in the tropics and mid-latitudes
Leading to increased flood risk in mid latitude regions
How can anthropogenic green house gas emissions lead to increasing incidence and severity of drought?
Increased intense high-pressure systems in certain seasons or high pressures regions e.g. subtropics and direr soils
What are the problems with predicting future climate change?
Not 100% sure of the future impacts of climate change
What were the difference between hurricane Harvey and Katrina?
Harvey= 14-15 trillion gallons (at august 28) 5 trillion more gallons predicted
Katrina= 6.5 trillion gallons
What can cause the climate to change short term?
Oscillations in wind patterns
What is an example of a influential short term change in wind patterns?
ENSO cycle
El Niño southern oscillation
