Singapore. Climate change has likely intensified the monsoon rains that have triggered record floods in Australia's Queensland state, scientists said on Wednesday, with several months of heavy rain and storms still to come.

But while scientists say a warmer world is predicted to lead to more intense droughts and floods, it wasn't yet possible to say if climate change would trigger stronger La Nina and El Nino weather patterns that can cause weather chaos across the globe.

"I think people will end up concluding that at least some of the intensity of the monsoon in Queensland can be attributed to climate change," said Matthew England of the Climate Change Research Centre at the University of New South Wales in Sydney.

"The waters off Australia are the warmest ever measured and those waters provide moisture to the atmosphere for the Queensland and northern Australia monsoon," he told Reuters.

The Queensland floods have killed 16 people since the downpour started last month, inundating towns, crippling coal mining and are now swamping the state's main city of Brisbane.

The rains have been blamed on one of the strongest La Nina patterns ever recorded. La Nina is a cooling of ocean temperatures in the east and central Pacific, which usually leads to more rain over much of Australia, Indonesia and other parts of Southeast Asia.

This is because the phenomena leads to stronger easterly winds in the tropics that pile up warm water in the western Pacific and around Australia. Indonesia said on Wednesday it expected prolonged rains until June.
