Resumo de Recurso
P2: Global Warming
Upsetting the greenhouse effect
Earth varies naturally
Due to movement around Sun
E.g. caused ice ages
Scientific consensus humans are causing increase in greenhouse gasses
Increase in carbon dioxide levels
Global temperature has also increased
The CO2 increase is not due to natural variation
Humans are causing global warming
Greenhouse effect increased
Causing global warming
A form of climate change that can cause others, e.g. changing weather patterns
Climate Model
Mimic what's going on in the real climate
Explain why the climate is changing
Know it varies naturally
These changes aren't due to natural variation
Shows increase in greenhouse gasses caused by humans
Input data and equations to work out climate
Surface temperature of ocean
Current speed and direction
Air temperature of places around the workd
Consequences
Sea levels rise
Hotter water expands
Flooding in low-lying areas
Netherlands
East-Anglia
Maldives
Ice melts
Loss of habitat for Polar Bear :(
Water flows into seas
Sea leves rise
Weather patterns
More extreme weather
Longer, hotter droughts
More frequent hurricanes
Form in seas above 27C
Increase in global temperature = increase in water temperature
More places above 27C
Increased heat in atmosphere
Stronger wind
More vater vapour
Increased chance of flooding and storms
Destroy homes/ crops
Food production
Droughts
Too dry to grow crops
Flooding
Too wet to grow crops
