New study links extreme weather to climate change

Feb 25, 2013
A corn crop dries up in a field pictured July 28, 2011 near Perryton, Texas. Scientists said Monday they have identified a physical mechanism behind the extreme weather that has plagued many parts of the world in recent years—and that it is tied to climate change.

Scientists said Monday they have identified a physical mechanism behind the extreme weather that has plagued many parts of the world in recent years—and that it is tied to climate change.

Since 2010, for example, the United States and Russia have each suffered scorching , while Pakistan saw unprecedented flooding.

Scientists from the Potsdam Institute for Climate Impact Research (PIK) have traced the events to a disturbance in the air currents in the , in a new study out Monday in the .

"An important part of the global air motion in the mid-latitudes of the Earth normally takes the form of waves wandering around the planet, oscillating between the tropical and the Arctic regions," lead author Vladimir Petoukhov said in a statement.

"During several recent , these planetary waves almost freeze in their tracks for weeks. So instead of bringing in cool air after having brought warm air in before, the heat just stays," he said.

In an ecosystem ill-adapted to long periods of extreme heat, the stress can be disastrous, with high death tolls, , and .

For instance, during Russia's 2010 heat wave—the worst in its recorded history—wildfires spread out of control, killing dozens of people, burning down thousands of houses and threatening military and nuclear installations.

Global warming, despite its name, is not uniform across the planet. At the poles the bump in temperatures—amplified by shrinking snow cover and ice—is greater than in the swathes between, the scientists explained.

This reduces the temperature differences between the Arctic and the middle latitudes, which affects the flow of air around the globe.

In addition, continents heat and cool more rapidly than large bodies of water, the scientists said.

These two factors "result in an unnatural pattern of the mid-latitude air flow, so that for extended periods the slow synoptic waves get trapped," Petoukhov said.

Fellow author and PIK director Hans Joachim Schellnhuber cautioned that the 32-year period used in the study is too short for definitive conclusions.

"The suggested physical process increases the probability of weather extremes, but additional factors certainly play a role as well, including natural variability," he added.

Nevertheless, he called the new research "quite a breakthrough," that helps explain the relationship between the spate of weather extremes and climate change.

I believe I have read that weather variability increased with climate change either warmer or colder. However, Isn't it true the geologic record shows greater variability and extremes of weather during cooling climate conditions? That maybe is just because in the geologic record only cooling occurs rapidly and warming climate is a geological slower process (previous to industrialization)?

New study links extreme weather to climate change


It seems to be a Dauhhh moment when you read the obvious! Extreme weather is with 100% certainty connected to climate change. And there is a 100% certainty that climate change is from excessive CO2 in the atmosphere!

You stupid nut suckers just need to all be rounded up and sent to the Al Gore treatment camp for the re-education of the dim ones. You deniers certainly qualify.

Seriously though, climate change is causing many issue that man-kind needs to deal with, in-spite of the 1%'s money flood of disinformation. So denier's read between my fingers and enjoy your spin.

Alarm is in the mind of the beholder ( to coin a phrase ) I would suggest the opposite. Science is merely exploring the options of a warming world. Neither you nor other "contrarians" can alter the fact that the worlds climate scientists come to a "consensus" about the AGW. It is not perfect but as Churchill said. "Democracy is the worst form of Government - except for all the others that have been tried".
So my friend the problem is yours - if you find it alarming, well you know, it may actually BE alarming. So we damn well aught to do something about it ( sustainably ) and not come on here railing about a world you don't want to be part of.

"All the usual extreme Alarmist comments." Good call Runrig. Freakin morons like this guy just need to be put in there place. Clueless about their environment, or there dependence on it. It doesn't matter to them (and they assume it doesn't matter to anyone else).

I'm not like that; the Environment is what makes the economy move. Bad environment, bad economy. Good environment, good economy. That is a tested fact our anti-global-warming friends should learn. He's out of a job if food isn't grown. He's out of a job the shore-line moves inward a few miles. He's out of a job if the outside air-temp is so high, people don't work.

This confinement of recursive hypotheses to a small "echo chamber" reflects the wider phenomenon of radical climate denial, whose ability to generate the appearance of a widely held opinion on the internet is disproportionate to the smaller number of people who actually hold those views (e.g., Leviston, Walker, & Morwinski, 2012). This discrepancy is greatest for the small group of people who deny that the climate is changing (around 6% of respondents; Leviston et al., 2012). Members of this small group believe that their denial is shared by roughly half the population. Thus, although an understanding of science denial is essential given the importance of climate change and the demonstrable role of the blogosphere in delaying mitigative action, it is arguably best met by underscoring the breadth of consensus among scientists (Ding et al 2011; Lewandowsky, Gignac, & Vaughan, 2012) rather than by direct engagement

Maggnus, you're the one hung-up on conspiracy. Never once have I claimed conspiracy amongst the AGW research whores.

I have, however, likened AGW to a grant-money bandwagon, and I stand by that.

But I suppose if a highly-educated researcher can show a proclivity for producing biased research, he/she can go to work for Bayer Crop Science, Monsanto, or maybe even the government. These entities are always looking for a good "yes man" who will do exactly what they're told to do and when to do it.

Such people must be able to subordinate integrity to their personal interests. AGW researchers fit the bill.

In recent years, the Northern Hemisphere has suffered several devastating regional summer weather extremes, such as the European heat wave in 2003, the Russian heat wave and the Indus river flood in Pakistan in 2010, and the heat wave in the United States in 2011.

Here, we propose a common mechanism for the generation of persistent longitudinal planetary-scale high-amplitude patterns of the atmospheric circulation in the Northern Hemisphere midlatitudes. Those patterns—with zonal wave numbers m = 6, 7, or 8—are characteristic of the above extremes.

Cont
VendicarE

Cont...

We show that these patterns might result from trapping within midlatitude waveguides of free synoptic waves with zonal wave numbers k ˜ m. Usually, the quasistationary dynamical response with the above wave numbers m to climatological mean thermal and orographic forcing is weak. Such midlatitude waveguides, however, may favor a strong magnification of that response through quasiresonance.
