From the ABC The federal Environment Minister says a climate change report warning of more erratic weather and rising sea levels is not cause for alarm. The new government report on climate change says there could be more droughts and storms, higher temperatures and rising sea levels in the next 30 to 50 years. The Climate Change: Risk and Vulnerability report predicts more possible threats to water supplies, ecosystems and agriculture. Environment Minister Ian Campbell says the report is evidence that even if all greenhouse gas emissions were stopped tomorrow, climate change would continue because of the build-up in the atmosphere. Senator Campbell says the warning could be painted as alarming but there is no need to panic.
