The impact of climate change is a critical issue worldwide. Greening Australia is stepping up the scale of its work to meet the challenge.
The need to reduce the amount of greenhouse gases produced by human activity (particularly by burning fossil fuels and land clearing) to slow down global climate change is now recognised worldwide by governments, industry and the community as more urgent than ever.
Climate change is caused by an increase in greenhouse gases in the Earth's atmosphere. Gases can be naturally-occurring or manufactured, with carbon dioxide (C02) a major contributing gas to global warming.
Trees use up carbon dioxide as they grow, converting it to wood, leaves, roots and bark. In fact, about half of the dry weight of a tree is carbon. As a result trees provide long-term stable storehouses of carbon that would otherwise contribute to the surplus of carbon dioxide in the atmosphere.
The capacity of species to adapt to climate change is being degraded and interrupted by the same threats driving the current biodiversity extinction crisis. Since climate change is expected to exacerbate existing threats, a generally appropriate response is to improve the resilience of natural systems and their ability to adapt by abating critical threats in the usual ways. However, the scale, intensity and pace of response to many of these problems needs to be substantially increased. Increasing the viability of depleted or fragmented plant and animal populations through habitat expansion and reconnection is a key objective, as is facilitating species dispersal by increasing structural connectivity, vegetation buffers, stepping stones and mosaic habitats.
For this reason, Greening Australia is actively addressing climate change through large landscape-scale plantings within our visionary projects, in addition to encouraging all Australians to reduce their ecological footprint - an equally important step in reducing the level of carbon dioxide in the atmosphere.
