The usual German media outlets today feature the usual scientists who are out in force spreading the dreck science that global warming is leading to more weather extremes, and La Ninas.
These “scientists” are from the usual source: the alarmist Potsdam Institute For Climate Impact Research (PIK). Amazingly, one of these scientists even claims that the current La Nina is warm, and caused by global warming.
The interviews come on the heels of Der Spiegel’s report late last week on a paper appearing in Science that shows just the opposite has been true in history: Warming leads to milder climates, which lead to human prosperity.
German Stern magazine did an interview with PIK scientist Anders Levermann, who is a lead author on the IPCC 5th Assessment Report on the subject of sea level. Here’s his comment on the media-ballyhooed weather extremes we’ve been hearing about:
Certain is: In a rapidly warming world, we will experience more frequent stronger extreme weather events like flooding, droughts and high winds.”
Everything is caused by global warming – even the “record snowfalls in Germany”. Other than sci-fi reports from reinsurer Munich Re, I have yet to see one scientific report that links these weather events to global warming. In fact Accumulated Cyclone Energy last year reached a record low.
On the Australian floods, Levermann attributes them to warm waters around Australia, in combination with the current La Nina, which he says:
Together with the La Niña climate phenomena, which provides a warming of natural origin, the warmer water temperatures lead to the worst rainfalls in a 100 years. The higher ocean temperatures in turn are very likely a consequence of global warming.”
[Update: To be fair, Levermann here most likely meant: The higher ocean temperatures near Australia (and not the Pacific in general) in turn are very likely a consequence of global warming. I guess he wants to say the La Nina pushed the warm water to Australia, and this water is warmer than usual because of warming. The statement he makes above is very misleading, to say the least].
On weather extremes in Germany this winter, Levermann serves up this observation (fantasy):
In any case one has to say that the snowfall of last winter was unusual. Also this winter was a record winter when compared with the past 100 years. Such 100-year records are tumbling one after the other, and it’s going to happen even more often in the future.”
Rahmstorf says there’s a connection (but he doesn’t see it yet)
The online Handlesblatt also features an interview with PIK Prince of Panic Stefan Rahmstorf about the same weather extremes. The Handelsblatt asks Rahmstorf if it is connected to global warming:
The planet is getting hotter and wetter. 2010, together with 2005, was the warmest year since measurements began, and it was also the one with the most precipitation. Also the increase in devastating floods can be explained by global warming says Stefan Rahmstorf of the Potsdam Institute For Climate Impact Research (PIK).”
Everything today can be attributed to global warming. The theory is unfalsifiable. If it happens, it’s because of global warming. Anf if it doesn’t happen (droughts), that too is because of global warming.
The Handelsblatt then asks Rahmstorf if the floods in Australia and Brazil are not the results of the La Nina? Here’s Rahmstorf’s reply:
Of course these events are, in the forefront, traced back to La Niña. But the change between El Niño and La Niña is a cyclic phenomena occurring every three to seven years. But that does not explain why this year records which have stood for 100 years have been broken. There are experts who believe that the fluctuations between El Niño and La Niña are more severe. Right now we are having an Extreme-La-Niña. In 1998 we had the most extreme El Niño.”
His colleague Levermann suggests it’s because of global warming. Note that Rahmstorf cites some experts who say so. But what does Rahmstorf himself believe? Handelsblatt:
But I do believe that it’s still too early to robustly show there is indeed a change.”
This has been typical of Rahmstorf and PIK lately, having it both ways. Notice how he starts by claiming that the extremes are due to global warming, and that the ENSOs are getting more extreme too. But then he says he can’t robustly show a connection between global warming and ENSO extremes. It’s there, it just can’t be shown.
Just another day at the PIK. Doing all it can to link everything to global warming.
