More warmists discover natural variability

The world could get colder over the next two decades - but still hotter in the long run, expert predicts | Mail Online
The world could get colder over the next two decades because of natural changes in the Earth's climate, a leading environmental scientist has warned.

Dr Mojib Latif, one of the world's top climate modellers, believes predictions of imminent global warming may be wrong and that the Earth could be heading for up to 20 years of cooler temperatures.
...
'People will say this is global warming disappearing,' he told more than 1,500 climate scientists at the UN's World Climate conference in Geneva last week.

Dr Latif, an author of the UN's Intergovernmental Panel on Climate Change and climate physicist at the University of Kiel, Germany, is the latest scientist to question short term predictions of global warming.

His model forecasts that a natural cooling trend could dominate over the next decade - offsetting any rise in temperatures caused by humans...
...
Risking the wrath of other climatologists, he said the NAO may have been responsible for some of the rapid rise in temperatures of the last three decades.

'But how much? The jury is still out,' he told the conference.
...
The world's warmest year in recent history - 1998 - was caused by an unusually strong El Nino.

Vicky Pope of the Met Office said natural variability was as important as the long term warming trend when predicting climate change over the next few years.

'In many ways we know more about what will happen in the 2050s than next year,' she said.

Dr Pope also warned the conference that the dramatic Arctic ice loss in recent summers was partly a product of natural climate cycles - and not just caused by man-made global warming. Early reports suggest there has been less melting this year than in 2007 and 2008.
