[G]olbal Warming by Mind Map: [G]olbal Warming

1. [C]auses of Global Warming

1.1. [H]uman activities

1.1.1. Sharp rise in greenhouse gases

1.1.1.1. [E]nhanced greenhouse effect

1.1.1.1.1. [M]ore heat trapped

1.2. [F]actors leading to rise in greenhouse emissions

1.2.1. [R]apid increase in use of fossil fuels

1.2.2. [L]arge-scale deforestation,forest fire(less CO2 absorbed from atmosphere)

1.2.3. [W]et rice cultivation(use of organic fertilsers)

1.2.4. [C]attle ranching (animals digestive processes)

2. [C]onsequences Of Global Warming

2.1. [M]elting ice and Rising sea levels

2.1.1. [S]atellite images show decreasing ice cover in polar regions

2.1.2. [S]cientists predict sea levels will rise about 1mm to 2mm per year

2.1.3. [L]ow-lying coastal countries become vulnerable

2.1.4. [E]stimated 100million perople threatened by possibility of flooding

2.2. [E]xtreme weather condition

2.2.1. [H]eat wave and [D]roughts

2.2.1.1. [H]ot and dry places experience more droughts

2.2.1.2. [H]igh temperature = [H]igh evaporation rates

2.2.1.3. [L]ess water vapour = [L]ess clouds =[L]ittle rain

2.2.1.4. [S]ignificant temperature results in high no. of deaths.

2.2.1.5. [H]eat waves can also cause forest fire

2.2.2. [S]evere storms

2.2.2.1. [R]egions with wetter climates experience higher relative humidity as there is more evaporation

2.2.2.2. [R]ainfall increases, leading to floods

2.2.2.3. [W]armer ocean temperatures = [M]ore intense tropical storms

2.2.2.4. [M]ore major hurricanes form, flood and destroyhomes, industories and infrastructure

2.3. [I]mpact on plants and animals

2.3.1. [C]hanges in flowering patterns of plants and breeding patterns of animals

2.3.2. [E]ncourages rapid breeding of insects eg. mosquitoes

2.3.3. [A]nimals forced to migrate or threaened with extinction

3. [S]olutions

3.1. [I]nternational

3.1.1. Kyoto Protocol

3.1.1.1. [I]nteratonal treaty on climate change

3.1.1.2. [S]igned in Kyoyo, Japan Dec 1997

3.1.1.3. [C]ountries acceded to work towards reducing emissions of greenhouse gases

3.2. [N]ational

3.2.1. [I]mpose carbon taxes

3.2.2. [R]eplant/retain forests to absorb CO2

3.2.3. [I]ntroduce measures to save electricity

3.2.4. [R]educe use of chemical fertilisers containing nitrogen

3.2.5. [B]an use of CFCs

3.3. [I]ndividual

3.3.1. [S]witch off electrical appliances when not in use

3.3.2. [U]se public transport

3.3.3. [B]uy only non-CFCs products
