Climate change

What are the causes of climate change?

Climate change is one of the biggest challenges we are facing today.

Since the late 19th century, the global average temperature has increased by between 0.2 and 0.6°C. The rise of global temperature is causing our climate to change much more than natural climate variability during the past century.

In the Fourth Assessment Report (2007), the IPCC concludes that global warming has accelerated in recent decades, and there is new and stronger evidence that warming over the past 50 years is attributable to the increase in greenhouse gas (GHG) emissions associated with human activities.

Human activities, such as the burning of fossil fuels and the clearing of land through deforestation, impact our climate faster and more severely than predicted through global warming as the concentration of GHGs rises in our atmosphere.

Scientific consensus is that we need to reduce emissions 80% by 2050 (against a baseline of 1990 levels) to stabilise our climate and prevent unprecedented negative impacts on the economy and our climate.


What are the impacts of climate change?

As global temperatures continue to rise, rain patterns are changing, sea level is rising, and snow and ice are melting sooner in the spring. These changes affect people, animals, and ecosystems in many ways.

According to the Steffen Report 'Climate Change 2009: Faster Change and More Serious Risks' produced by the Australian National University on behalf of the Commonwealth Department of Climate Change (a copy of the report is available here), critical risks for Australia include:

  • sea level rise;
  • ocean acidification (when carbon dioxide reacts with water to create carbonic acid);
  • severe recurring droughts and drying trends;
  • increase in extreme weather events such as heat waves, bushfires and floods.

Adapting to climate change

We, as a responsible society, have the ability to tackle climate change.

Climate change is already happening. The weather and many parts of our lives will be impacted. Climate change adaptation is about what can be done differently to manage that change.

At Greenfleet we believe that we all need to avoid and reduce GHG emissions, and then offset them by revegetating cleared land with native forests, to reach the low carbon future our society and planet need to survive.

Take action today to reduce your emissions thanks to our tips and offset your emissions with Greenfleet, helping restore more native forests in Australia
