An important thing to realise when thinking about climate is that, atmospheric and oceanic circulation carries different climatic features all over the planet. For example, the emissions of greenhouse gases from industry in the Northern Hemisphere may contribute to increasing the Greenhouse Effect, which has implications for the entire planet. The days of "dump it in your own backyard" are over, as we realise that there is only one big planetary backyard! An increase in our industrial, agricultural and energy practises in the last 150 or so years has contributed to a build up of 'Greenhouse' gases in the atmosphere. These gases are primarily responsible for global warming and ozone depletion. Climate change is becoming an ever more important issue in our lives. Some of the climatic problems that are developing today, such as global warming, ozone depletion and El Nino, will have severe effects on reef ecosystems all around the world. Reefs might give us an early indication of the effects of global climate changes, as slight variations in sea temperature caused by climatic variations have already been shown to produce extreme responses from reef ecosystems. 

Solutions to the problems of climate change and reefs exist on a number of levels. It is important for Govts to realize the urgency of the situation as reefs are not going to be able to withstand such dramatic changes in climate for long. Govts should have a responsibility to educate both public & industry about these hazards. Laws banning the production of CFC gases would help to slow down the rate of ozone depletion and global warming.We individuals can help by reducing our energy consumption (turn off lights , walk /shared car instead of drive ) therefore reducing the amount of fossil fuels (which release CO2) that are burnt for us.

No problem is too big for anyone to help a litte bit. The reef might feel far away from each individual but we can do our bit to help save reef by doing few simple things like

Don?t buy aerosol cans that are powered by CFC gases so that there is no demand and its manufacturing reduces or stops.

Take public transport /shared car rather than own car emitting gases , using fuels?

Reduce the intake of meat as most of the deforestation in the world is so that cows can eat grass. Forests produce oxygen and eat up CO2 , while cows produce a lot of methane.

These things seem small but they can really help solve the problems of climate change . Imagine if everybody did this , there would hardly be a problem at all.
