Hurstville City Council is committed to working with the Hurstville City community to reduce the chance of climate change and helping residents save energy in the home.
Worldwide scientific opinion indicates the planet's climate is changing due to human activity. The results include increased frequency of droughts, floods and severe storms. Greenhouse gases (water vapour, carbon dioxide, methane and nitrous oxide) are a natural part of the earth’s atmosphere. Since the industrial revolution the concentration of greenhouse gases in the atmosphere has increased significantly, mainly due to the burning of fossil fuels and land clearing. Rising greenhouse gas emissions trap more heat in the atmosphere causing global warming and climate change – this is known as the enhanced greenhouse effect.
Although the world goes through cycles of warming and cooling, the speed at which it is occurring has increased significantly in the last decades so that natural systems cannot adapt and cope.
What this means for Hurstville and the Sydney region is that:
- Sea level is almost certain to rise, projected to rise by 0.4 m by 2050 and 0.9 m by 2100.*
- Temperatures are almost certain to increase, projected daily minimum and maximums increasing by 1.5-3oC by 2050.*
- Extreme heat days over 35 oC in Sydney will increase from an average of 3.5 days per year in 2013 up to 12 days per year in 2070.^
- Natural hazards such as fires, floods, erosion and droughts will increase in frequency and severity.^
- Therefore homes, recreational areas and natural reserves will be under increasing risks.^
- Likewise ecosystems, animals and plant species will be more threatened especially vulnerable species and habitats that are already under risk.^
