Are we facing a warmer summer?

The previous projections were for a global mean temperature increase between 0.8 and 3.5 degrees C, but the new projections are for 1.3 to 4.0 degrees C. This warming is at a rate 2 to 7 times more rapid than that of the 20th century.

The effects of global warming are predicted to include a rise in sea levels as the water becomes warmer; shifting climatic zones that change how and where we grow our food; and the spread of disease as temperatures rise.

"But the news is not all bad. It is possible to reduce production of the greenhouse gases that cause global warming" said Kathy Fook, of the Community Information Project on Sustainable Energy (CIPSE). "The average home uses around 8,500 kWh of electricity every year, which costs about $750, and generates over 18 tonnes of greenhouse gases."

"But just by adopting a few 'Energy Smart' measures, energy consumption can be reduced by about 1,300 kWh, saving the householder around $150 every year, and reducing greenhouse gas emissions".

Energy Smart measures include fitting efficient shower heads, door seals and draught stoppers, compact fluourescent lighting, ceiling insulation, and tap aerators on the bathroom basin and kitchen sink. Using energy efficient appliances and solar hot water also helps.
