Water vapour study

"Scientists have underestimated the role that water vapour plays in determining global temperature changes, according to a new study that could fuel further attacks on the science of climate change.

The research, led by one of the world's top climate scientists, suggests that almost one-third of the global warming recorded during the 1990s was due to an increase in water vapour in the high atmosphere, not human emissions of greenhouse gases. A subsequent decline in water vapour after 2000 could explain a recent slowdown in global temperature rise, the scientists add.

The experts say their research does not undermine the scientific consensus that emissions of greenhouse gases from human activity drive global warming, but they call for "closer examination" of the way climate computer models consider water vapour."

A new report in Science underscores what many scientists have been saying for years, it's water vapor, not CO2, that has been driving global temperature changes in recent decades. Stratospheric water vapor concentrations decreased by about 10% after the year 2000, slowing the rate of global surface temperature increase over the past 10 years. It also seems likely that water vapor in the stratosphere increased between 1980 and 2000, causing surface temperatures to warm by an extra 30% during the 1990s. These findings show that stratospheric water vapor represents an important driver of decadal global surface climate change, yet the IPCC crowd continues to focus on CO2.

Not CO2? Please don't talk such rubbish here. Learn the science behind the headline. Here's the sensible approach to Sue Soloman's paper.

If you're going to take the ivory tower approach please ensure that other members of your tribe don't make trivial errors and get caught lying in public if you want to be taken seriously.

Who made a trivial error? (No don't answer that. If it was trivial it doesn't matter.)

Who lied in public?
