Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worldÂ’s ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable.
On 20 November 2006 the Biological Diversity Advisory Committee (BDAC), whose role it was to advise the then Australian Government Minister for the Environment and Heritage, held a one day workshop in Canberra on climate change and invasive speciesÂ’ impacts on biodiversity. Eight talks were given, followed by a session of free discussion. Most attendees were experts from government departments, universities, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and cooperative research centres (CRCs).
Climate change is expected to cause extinctions when native plants and animals are prevented from migrating out of their hotter or drier habitats to more suitable climates. But for many species a more
