What is Climate Change?
..What Causes Climate Change?
….What is the impact of Climate Change?
……Why should I care?
These are some of the questions regularly heard around the world. The first one and most certainly the last one are relatively straightforward to answer. What the causes are is now fairly clear for everyone to see. The issue of how extensive the impact will be and over what timeframe is the subject of heated debate!
WHAT CAUSES CLIMATE CHANGE?
The Earth’s climate is an incredibly complex system, thus it is not easy to be 100% precise over the exact causes and level of impact of differing factors on climate change. However what is clear is that climate change is taking place, there is strong scientific evidence to prove this. The two fundamental causes of this change are naturally occurring change and human causes. Expert opinion is clear that whilst human causes may not be the sole cause, they are certainly a major contributory factor.
* Human Causes:
Scientific opinion across the world agrees that the largest single cause of climate change is the increased levels of greenhouse gases; specifically Carbon Dioxide (CO2) released into the atmosphere. The greatest cause of CO2 emissions is the burning of fossil fuels (coal, gas, oil etc.) used to generate power, specifically electricity. Electricity and power are used in large scale industrial production, but is also used on a day by day basis by all of us in our normal daily lives; the heating and lighting in our homes, the planes, trains and cars we travel in, the technology and gadgets from televisions to computers etc, all use power and often continue to use more than is necessary when left switched on / on standby.
* Natural Causes:
There is evidence that the earth’s climate changes naturally over long periods of time. Historically we have all read about the Ice Age 10,000 years ago in history books. It seems that this was part of a pattern of fundamental changes to our climate over very long periods of time and that the current climatic changes are part of this pattern. However scientific opinion suggests that any change that may be due to natural causes is being accelerated by human causes.
Solutions :
Climate change through global warming can be tackled ‘globally’ and ‘locally’.
These actions are aimed at slowing climate change and to ultimately stabilise it.
International actions:
Global strategies already in place due to International Conventions:
●Kyoto Protocol which aims to reduce carbon dioxide emissions: unfortunately not all countries have agreed with the targets that have been set.
●Montreal Protocol which aims to stop the use of CFCs and find suitable ‘environmentally’ friendly substitutes.
Other global strategies to slow climate change:
●Reduce deforestation: forests absorb large quantities of carbon dioxide for photosynthesis.
●Afforestation: plant trees to absorb carbon dioxide.
●Reduce methane emissions: some areas are easier to tackle than others such as methane from land-fill sites and leakage from gas pipelines and mining.
●Increase energy saving and conservation in homes and industry.
●Greater use of renewable sources of energy supply.
