Average weather includes variables like average temperature, precipitation, wind patterns and so on. The global climate changes are brought about by dynamic processes of Earth, external forces and also by human activities. In recent usage, especially in the context of environmental policy, the term “climate change” usually refers to changes in modern climate.

Causes of Climate Change

The causes of climate change can be divided into two categories, human and natural causes. It is now a global concern that the climatic changes occurring today have been speeded up because of man’s activities. The natural variability and the climate fluctuations of the climate system have always been part of the Earth’s history however there have been changes in concentrations of greenhouse gases in the atmosphere growing at an unprecedented rate and magnitude. The United Nations, governments and many top scientists around the world believe that we must act now to stabilise and arrest further changes.

To understand climate change fully, the causes of climate change must be first identified. Scientists divide the causes into two categories, natural and human causes.

Effects of Climate Change

It is difficult to precisely predict what the impacts of climate change will be, as they vary with each region. Best estimates are that by 2030 Australia will face:

  • a further 1 degree Celcius of warming in temperatures
  • up to 20 per cent more months of drought
  • up to 25 per cent increase in days of very high or extreme fire danger
  • increases in storm surges and severe weather events.

Consequences of Climate Change

The consequences of climate change can be seen in the UK and around the world. UK temperatures, including those of British coastal waters, have already risen. Globally, extreme weather is predicted to become more common and to have a negative impact on humans, animals and plants

Solutions of Climate Change

There are two fundamental ways we can help.

Firstly, make small lifestyle changes that reduce our personal use of energy. Our power stations are principally run by burning coal, so the less electricity we use, the less coal is burned and the less CO2 is emitted into the atmosphere. See some suggestions below on ways we can achieve this.

Secondly, plant trees and shrubs. All plants utilise a process called photosynthesis whereby they absorb equal parts of CO2 and water (H2O) to produce sugars for energy. For each six parts of CO2 and water, a plant produces one part of sugar and six parts of oxygen, which is released as a by-product. All plants store carbon so do not burn off your garden rubbish! This releases the carbon back into the atmosphere. It’s always best to compost your garden waste and return the material to the earth!

Tips to reduce our personal consumption of energy:
1. Turn off the air conditioner unless it’s absolutely necessary. Clean your air conditioner’s filter regularly to improve the unit’s efficiency. Put on a jumper instead of lighting the fire!
2. Turn off lights that aren’t needed. Change to low energy globes.
3. Minimise your use of the car. It’s burning fossil fuels directly! Try car pooling. Adopt better driving habits that minimise fuel consumption (saves money too!). Walk to the shops if you can!
4. Turn off electrical equipment at the power point. Even such things as TVs and computer monitors on stand-by are using energy.
5. Take shorter showers. This saves water and the energy needed to heat the water.
6. Ensure that dishwashers and washing machines are full to capacity before you turn them on.
