The earth is warming. There is no confusion. The only issue is how do we economically deal with the issue. I think it has moved from a RISK to an ISSUE that needs to be actively addressed.IQS.RLOW wrote:I see the bedwetting, handwringing, frybabies are still at it, confusing weather with climate when it suits themskippy wrote:Nice to see IQS has toned down his language and rage. :shock:It was hot as here this weekend.
World's climate warming faster than feared, scientists say
Scientists say the world’s climate is warming faster than feared because previous predictions were too “optimistic” and overestimated the cooling impact of clouds

As the planet marked its fourth hottest year on record, a study published in the journal Nature found increasing levels of carbon dioxide will lead to thinner ocean clouds and reduce their cooling impact, causing temperature rises of at least 5.6F (3C) over the course of the century.
The team of scientists said the findings show some climate models have been too “optimistic” and previous estimates of a minimum temperature rise of only 2.7F (1.5C) could now be discounted. The optimistic models did not properly assess the impact of water evaporation, which sometimes rises only a short distance into the atmosphere and causes updraughts that reduce cloud cover, the study found.
”These models have been predicting a lower climate sensitivity but we believe they’re incorrect,” Professor Steven Sherwood, from the University of New South Wales, told The Sydney Morning Herald.
”The net effect of [climate change] is you have less cloud cover.”
The study comes amid a controversy in Australia over claims by Maurice Newman, Prime Minister Tony Abbott’s top business adviser, who said the world had been taken “hostage to climate change madness”.
Mr Newman said the climate change establishment, led by the Intergovernmental Panel on Climate Change, remained “intent on exploiting the masses and extracting more money”.
“The scientific delusion, the religion behind the climate crusade, is crumbling,” he wrote in The Australian. “Global temperatures have gone nowhere for 17 years... If the IPCC were your financial adviser, you would have sacked it long ago.”
Mr Newman, a former chairman of the Australian Stock Exchange, was criticised by the opposition and pilloried by scientists, who said he was expressing “flat earth” views and should be sacked.
“His piece is a mix of common climate change myths, misinformation and ideology,” said Professor David Karoly, from the University of Melbourne, in an article in The Sydney Morning Herald.
“I would not choose a person who believes that the Earth is flat to advise Australian shipping or airline businesses on how to plan routes to travel around the world. It is clearly not sensible to have a person who believes that climate change science is a delusion as leader of the prime minister’s Business Advisory Council.”
Mr Abbott, who is something of a climate change sceptic, once claimed that “climate change is “absolute crap”, though he later said he accepts it is “real”.
Since winning a federal election last September, he has moved to scrap Labor’s tax on carbon emissions and instead proposes to address climate change by paying polluters to reduce emissions, though critics say the plan is underfunded and will not achieve its reduction targets.
The debate comes as Australia in 2013 marked its hottest year since reliable recordings began in 1910. The world’s driest continent also recorded its hottest day, hottest month, hottest winter’s day and hottest summer.
The run of warmer weather began late in 2012 and was so great that Australia’s Bureau of Meteorology last year changed its official weather forecasting map to include new colours - deep purple and pink - for areas with temperatures above 50C (122F).
Globally, according to figures released in December by the United States National Climatic Data Center, 2013 was set to be the fourth hottest year in 134 years of records behind 2010, 2005 and 1998.
Meteorologists said it was the hottest year on record for a non-El Niño year.
