Climate Change - Coggle Diagram
Climate Change
impacts of climate change
damage to human health
changes in water availability
distributions of biomes and crop growing areas
loss of biodiversity
coastal inundation
ocean acidification
increase in greenhouse gas concentrations
higher global average temperature
more frequent and intense heat waves
some areas becoming more prone to droughts
intense periods of rainfall and flooding
tropical storms be more powerful
human activities are increasing levels of greenhouse gases
an increase in the mean global temperature
increased frequency and intensity of extreme weather patterns
Hurricane katrina (2006)
hurricanes energy comes from warm oceans as more heat is trapped by GHG
warmer oceans means more energy available for storms which means stronger (extreme) storms
long term changes in climate and weather patterns
rise in sea levels
impact of climate change on human health and exacerbation of existing inequities
more extreme weather
degraded living conditions and social inequities
changes in vector ecology (malaria,dengue)
rising sea levels
air pollution (asthma)
water quality impacts (cholera)
increasing CO2 levels
water and food supply impacts
severe weather
rising temperatures
environmental degradation
extreme heat
solar radiation
weather and climate are both determined by the amount of solar radiation an area receives
this is due to latitude and the rotation on the earth on its axis
the amount of solar radiation affects the circulation of the air above an area
Nitrous Oxide (N2O)
result in natural process of nitrogen cycle
enhance by nitrogen containing fertilizers
high temperature of combustion fossil fuels
climate
describes how atmosphere behaves over relatively long periods of time
weather
describe the condition in the atmosphere over a short period of time
positive feedback cycle
higher temperature
increased in evaporation
more h2o vapor in atmosphere
evaporation require energy to do so
more heat trapped in atmosphere
greenhouse effects (higher temperature)
carbon dioxide
increased since industrial revolution
combustion of fossil fuels (coal, natural gas, petroleum)
deforestation (forest less=less absorption of CO2 from atm)
methane CH4
absorbs 20-30 timesmore heat than CO2
sources
landfills
rice paddies
agriculture
large scale of cattle ranching
HFCs
group of synthetic gases primarily used for cooling, refrigeration, fire extinguishe, aerosol
