Climate change in world natural disaster in world

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 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.
Weather Switch
The Pacific has historically switched between La Nina phases and El Ninos, which have the opposite impact by triggering droughts in Australia and Southeast Asia.

“The first thing we can say with La Nina and El Nino is it is now happening in a hotter world,” he told Reuters, adding that meant more evaporation from land and oceans, more moisture in the atmosphere and stronger weather patterns.
“So the El Nino droughts would be expected to be exacerbated and also La Nina floods because rainfall would be exacerbated,” he said, though adding it would be some years before any climate change impact on both phenomena might become clear.
He said the current La Nina was different because of the warmest ocean temperatures on record around Australia and record humidity in eastern Australia over the past 12 months.
Prominent US climate scientist Kevin Trenberth said the floods and the intense La Nina were a combination of factors.
He pointed to high ocean temperatures in the Indian Ocean near Indonesia early last year as well as the rapid onset of La Nina after the last El Nino ended in May.

He said a portion, about 0.5C, of the ocean temperatures around northern Australia, which are more than 1.5C above pre-1970 levels, could be attributed to global warming.
“The extra water vapor fuels the monsoon and thus alters the winds and the monsoon itself and so this likely increases the rainfall further,” said Trenberth, head of the Climate Analysis Section at the National Center for Atmospheric Research in        Boulder, Colorado.
“So it is easy to argue that 1 degree Celsius sea surface temperature anomalies give 10 to 15 percent increase in rainfall,” he added.
Some scientists said it was still too soon to draw a definite climate change link to the floods.
“It’s a natural phenomenon. We have no strong reason at the moment for saying this La Nina is any stronger than it would be even without humans,” said Neville Nicholls of Monash University in Melbourne and president of the Australian Meteorological and Oceanographic Society.
But he said global atmospheric warming of about 0.75C over the past half century had to be having some impact.
“It has to be affecting the climate, regionally and globally. It has to be affecting things like La Nina. But can you find a credible argument which says it’s made it worse? I can’t at the moment.”
