Climate change is having a negative effect on the earth. An alternative source of energy is required to tackle the problem of emissions from fossil fuels.
The UN’s Intergovernmental Panel on Climate Change (IPCC) has made a number of stark predictions on climate change. It says:
- Temperatures will rise by between 2.5 and 10 degrees Fahrenheit over the next century
- Hot days will become hotter and more frequent, by a factor of 10 around the world, if emissions are not tackled
- Sea levels are rising; heavy rain will occur more often and the wind speed of tropical cyclones will increase. More flooding is expected
Governments take action
In December 2011, 38 industrialised countries agreed to adopt a universal legal agreement on climate change. This will happen not later than 2015. Governments have agreed to turn their economy-wide targets into measured emission limitation or reduction objectives.
Did you know?
Global use of fossil fuels has contributed significantly to the increase in greenhouse gas emissions. Emissions in 2010 were 39% above pre-industrial levels. However, harnessing renewable energies such as geothermal power can reduce these levels.
