LAND COVER TRANSFORMATIONS & CLIMATE CHANGE
what is land cover?
different types of environments & features covering the Earth's surface
carbon cycle
carbon sinks
store carbon
:star: removing carbon sinks = more carbon in atmosphere
influences greenhouse effect
human enhanced greenhouse effect
:star: agriculture = emissions
:star: use of technology = burning of fossil fuels
govens where carbon is stored & what it is in
hydrological cycle
continuous movement of water around the world
water stored in different forms
land cover transformations
deforrestaion
urban development
damming
agriculture
irrigation
removal of ground water
melting of sea ice
desertification
albedo
reflective surfaces
:star: less high albedo surfaces = more heat stored in Earth
la nina & el nino
wind cells
farrel, hadley & polar
:explode: loss of biodiversity
:star: ocean salinity & temp changes
:star: loss of phytoplankton
:star: deforrestaion
:star: habitat loss
:star: loss of soil nutrients
:star: loss of food sources
:star: temp impacts
:star: animal migration changes
:star: invasive species
:star: changes in precipitation
:explode: synchrony of ecosystems
:explode: harder to grow food
:explode: loss of keystone species
anthropogenic & biophysical impacts
rising sea levels = flooding
spread of disease & displacement
increased frequency & severity of natural hazard zones
melting ice caps
:star: = antrhopogenic impacts
:explode: = impacts of loss of biodiversity
