Increase in sea levels & the increased risk of flooding in low lying coastal areas
Melting of Ice Caps
Other Environmental Effects Associated With Climate Change That Are Concerning Scientists Include:
Increased Incidents of Forest Fire in many Parts of the world
Increase in sea levels
•Melting of polar ice caps
•Changing of the Planet’s ecology such as the bleaching coral reefs; difficulty of growing crops in certain areas etc.
Increased Risk of Droughts
Ecology is Affected
Some areas -challenge growing crops
Bleaching coral reefs
Impacts on biodiversity etc.
Increased Risk of Floods
Normally, after a major environmental event -100s of 1000s of people are often displaced
–they are referred to as ‘Climate Refugees’.
Increase in Frequency of Extreme Climate Events
Energy
Even an overall 2°C rise in global surface temperature is Considered by scientists to be very dangerous

Impacts of Climate Change/Global Warming
Forests
Scientists are worried that due to global warming and climate change, ‘extreme’ climate events have become more frequent:
•Floods
•Droughts
•Heat Waves
•Hurricanes, Typhoons, Tornadoes etc.
Waste Disposal Activities –land filling (CH4)
Agricultural Activities –livestock farming (CH4)
Agricultural Activities –use of nitrogenous fertilizers (N2O); paddy cultivation (CH4)
Deforestation & Land-Use Change
Burning Of Fossil Fuels
Most scientists agree that the large increase of GHGs in the atmosphere is due to various human activities -mainly associated with the burning of fossil fuels like coal, oil, gas etc.
Global GHG Emissions
The most significant GHG is carbon dioxide (CO2), which makes up
77% of all global GHG emissions.
What is the greenhouse effect?
‘Greenhouse gases’ in the atmosphere absorb or trap infrared radiation, thus warming the Earth's surface. This is the greenhouse effect.
Global Warming & Climate Change
Global Warming & Climate Change is caused by the build up of Greenhouse Gases (GHGs), in the atmosphere.
