From the ABC
A CSIRO scientist is warning authorities not to interpret floods in eastern Australia and snowstorms over Europe and North America as signalling the end of global warming.
NASA research shows that 2010 is the hottest year on record.
Barry Hunt, an honorary research fellow at the CSIRO’s Marine and Atmospheric Research unit, says global temperatures will continue to rise even if there is another cold snap.
“Over the last century, the global mean temperature has gone up by 0.8 degrees [Celsius], and that’s the extent of the global warming, but at the same time, we also have natural climatic variation, and you don’t get one or the other, you get them both. They interact,” he said.
“I found that even up to 2040 and 2050, you can still get cold snaps under greenhouse warming.
“These last two or three months, you get them over Eurasia, or North America, and you can get temperatures 10 to 15 degrees below present temperatures, and that’s just natural variability, pulsing back briefly, overwhelming the greenhouse warming.
“The climate deniers think that unless you’ve got constant warming, every year, that greenhouse warming has gone away. And they forget about the natural variability.
“We should expect now to see the global warming trend take over again.”
Mr Hunt says although climate change sceptics are very vocal, the evidence is clear.
“The scientific basis is very sound,” he said.
“The basic long-term trend over the next 100 years is for a steady global warming, and over most of Australia we can expect to see rainfall decline.
“Despite the variability from year to year, there will be a long-term drying trend over most of Australia.”

The hallmark of winter is cold, at least in North America.
Even with climate change, you’re still going to wake up on a January morning and see snow falling. I walk to the bus stop, too, so I know about cold ears and fingers. As a climate scientist, I have plenty of compelling facts at hand about global warming, and trust me. You may want to remind your friends that weather is different from climate. It may seem counterintuitive, but we have strong evidence that heavier snows are actually one of many links scientists have uncovered between climate change and extreme weather
Enough already. I ask again: what physical evidence would need to be presented to overturn theories based on climate models? It is insufficient to assert that no matter what the temperature and rainfall, it is automatically consisted with a global warming hypothesis. It is time for people such as Hunt to mark a line in the sand which, if crossed, would mark a mea culpa.
