Consequences of Climate Change

1. Global warming due to green house effect by gases added in to the atmosphere and destruction of ozone layer.

2. Increased rainfall as a result of high temperatures causing high rates of evaporation causing wet areas to become wetter and dry areas to become drier.

3. Effect on agriculture by causing crop growing areas to shift to cooler altitudes and latitudes e.g. wheat growing areas of
Canada shifting to the poles and causing dropping or failure of crop yields in area where temperatures have increased.

4. Water shortage when climate becomes drier causing less water to infiltrate underground and hence less water to feed rivers.

5. Submergence of coastal areas causing flooding when Antarctic and Arctic glaciers melt and water is added to the oceans.

6. Heat waves due to increased temperature which leads to death of people.

7. Receding and disappearance of ice caps on mountains e.g. Mt. Ruwenzori.

8. Abnormal growth of plants due to increased amounts of co2 causing increased rate of photosynthesis which may lead to increased yields of major crops, poor soils due to soils having to sustain high rates of plant growth.

9. increased levels of ultra violet radiation which causes human diseases such as skin cancer, lowering crop production by slowing photosynthesis and germination, lowering fish population by damaging plankton which fish eats and degradation of paint and plastics.

Solution to Climate Change

- Afforestation and reafforestation.

- Use of energy saving stoves to reduce the rate of deforestation.

- Use of alternative sources of energy which are environmentally friendly e.g. solar and water instead of fossil fuels.

- Proper maintenance of vehicle to reduce emissions from their exhausts.

- Use of public transport to reduce the amount of fossil fuel used and hence the amount of co2 added into the atmosphere

Next: The graph in Fig.20 shows the disintegration per second versus time in seconds, s, for as sample of radioactive material
Previous: Figure 2 shows the path of radiation from a radioctive source after entering a magnetic field. The magnetic field is directed into the paper and is perpendicular to the plane of the paper as shown in the figure.
