- CLIMATE CHANGE
- Tropical Savannas Impact
- likely to get hotter. Would result in higher evapotranspiration and drought
- close to equator rainfall is likely to increase- may cause flooding and increase in water-borne diseases e.g. cholera
- but may increase agricultural productivity
- Further from equator rainfall is likely to decrease= increase drought and result in ecosystem change
- rainfall more variable
- Increasing sea level= flood low-lying areas & increased sea temp.=damage to coral reefs due to coral bleaching
- INTERNATIONAL RESPONSES TO GLOBAL WARMING
- KYOTO PROTOCOL
- an international agreement formed in 1997. 190 countries joined agreement to monitor and reduce greenhouse gas emissions
- agreement divided countries into DEVELOPED and DEVELOPING
- DEVELOPED agreed to cute emissions by 5% of 1990 levels by 2010
- DEVELOPING didn't have to cut emissions but needed to monitor and report them
- PROBLEMS
- 4 Countries with high emissions (USA, CHINA INDIA AND AUSTRALIA) didn't sign up
- believed it would effect economies and slow rate of growth
- whats the point if higher pollutants not involved?
- 4 Countries with high emissions (USA, CHINA INDIA AND AUSTRALIA) didn't sign up
- EARTH SUMMIT
- The
Earth summit followed in 1992 in Rio de Janeiro, and set up the United Nations
Framework Convention on Climate Change
- The objective of the UNFCCC was to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous human interference with the climate system.

- KYOTO PROTOCOL
- NATIONAL RESPONSES TO GLOBAL WARMING
- CHANGE ENERGY MIX OF COUNTRY
- energy mix is mix of energy sources to meet its energy needs
- e.g. fossil fuels, nuclear power. FRANCE 3/4 OF POWER FROM NUCLEAR
- Replacing fossil fuels with nuclear power and renewable energy can help reduce climate change reducing emissions from power stations
- UK- 40% emissions reduced by 2020 will be achieved with 30% of elec from renewable
- More offshore wind farms being built, tidal power projects, solar panels, wind turbines
- BUT
- Needs more investment in nuclear and renewable to meet all energy needs so still use fossil fuels till that happens
- environmental issues with nuclear power etc with waste
- disrupt coastal environments
- BUT
- energy mix is mix of energy sources to meet its energy needs
- USE OF NEW TECHNOLOGIES TO CUT EMISSIONS FROM POWER STATIONS
- Carbon capture and storage (CCS) reduce climate change by reducing emissions at power stations
- involves capturing co2 and transporting it to where it can be stored safely in deep geological formations
- BUT
- technology still at development stage and problems identified
- carbon may leak
- Carbon capture and storage (CCS) reduce climate change by reducing emissions at power stations
- ENCOURAGING ENERGY CONSERVATION AT HOME
- reduce domestic fuel consumption
- Financial incentives being offered to people who generated own elect through solar pannels etc
- BUT
- high initial cost// difficult to work out how energy efficient some houses are// restrictions on listed buildings
- BUT
- REDUCE EMISSIONS FROM TRANSPORT
- Encourage people to buy lower emissions vehicles
- road tax free cars
- incentives to those buying electric cars and hybrids
- BUT
- large number of old cars still on road
- Expensive
- producing electric cars still produce emissions
- BUT
- Encourage people to buy lower emissions vehicles
- CHANGE ENERGY MIX OF COUNTRY
- LOCAL RESPONSES TO GLOBAL WARMING
- Recycling Waste
- less energy to recycle thanmake from scratch
- UK prevents release of 10million tonnes of CO2 each year
- transportation=emissions
- less energy to recycle thanmake from scratch
- Using cars less
- reduce transport emissions
- cars produce 2.7tonness of CO2
- people prefer cars-safer faster etc
- reduce transport emissions
- Buy Local
- buying local produce=reduce transport emissions
- heated greenhouse=high emissions
- people like to have access to variety all year
- buying local produce=reduce transport emissions
- Energy efficent Appliances
- reduce fuel consumption
- 50%more efficent than older models
- throwing away of old=waster
- making new= emissions
- Recycling Waste
- Tropical Savannas Impact
