Doctors for the Environment Australia (DEA) has major concerns about the expected effects of climate change on human health and well being. We have recently released nationally and internationally a report on this topic. It is therefore appropriate that we submit to this Senate Committee to emphasise that a significant reduction in greenhouse gas emissions is urgent and the only way that this can be quickly accomplished is by encouraging energy saving and expanding renewable energy provision. The situation is urgent because recent scientific reports are showing that the harmful effects of climate change are arising much faster than anticipated from IPCC data. There is increasing danger that climate change may become irreversible.
