Climate change news

Steam rising as the sea level hockey stick is published, in pronto timescales

Over at http://climateaudit.org/2011/06/22/pnas-reviews-preferential-standards-f... ... Steve McIntyre is critical not just at the ease at which the Team paper went through peer review at PNAS, in stark contrast to their treatment of Lindzen (see post a week ago) but the contents itself - which he thinks are misleading. For example, the proxy data has been smoothed by Bayesian methodology - in a way statisticians would not encourage. It seems they also exclude sea level data before AD1000 yet claims it is a seal level record over the last 2000+ years.

Palaeo-climate change

A story at www.physorg.com/print227772631.html ... scientists are taking samples of soil that formed up to 20,000 years ago to find out what was growing in the Hackensack Basin from then until now. The basin was formed by a glacier in the last Ice Age and when it shrank back a lake formed there. It seems that the 20,000 years figure might be somewhat loaded as the lake itself did not drain away or dry up until some point between 10,000 and 7,000 years ago, possibly at the onset of the Mid Holocene Warm Period - 8,000 years ago.

Giving birth to the sea level hockey stick

Amazingly, after the mess the AGW 'Team' got themselves into over the temperature hockey stick model, climate scientists have produced another progeny - this time with sea levels (see http://wattsupwiththat.com/2011/06/20/manns-new-sea-level-hockey-stick-p... ).

Points of Climate view

At www.bishop-hill.net/blog/2011/6/16/ideological-money-laundering.html ... this story is based on some muddling around and genuine research by Steve McIntyre over at www.climateaudit.org and a reaction to it by Mark Lynas, the author of several pro-AGW books and a climate change blogger still insisting the science is right. Obviously, he reads the McIntyre blog - and also Bishop Hill as he made a comment. Lots of people who are not sceptic must read the blogs just to see where the other side is at - and Steve McIntyre hit the needle on its head.

Bats, the furry things, and Vikings, the bearded ones

At www,cell.com/current-biology/abstract/S0960-9822(08)0075-3 there is an abstract of an article in Current Biology on bat fatalities near wind turbines, and one of the causes is called barotrauma - rapid air pressure reduction changes that creates damage to their lungs due to an expansion of air in the lungs that is not accommodated by the appropriate exhalation. Contact with blades was perhaps responsible for half the bat fatalities but barotrauma was a strong secondarily cause.

Solar doomsaying

It seems the sceptic blogosphere is doing a bit of doomsaying of it's own over the last few days - latching on to a controversial claim that the next Sun cycle (we are only half way through the present one) will be void of sun spots - like the Maunder Minimum of the Little Ice Age. We don't know but some sceptics are getting excited - if the world enters a new very cold phase of climate that might put to bed AGW but it will be a tragedy. Cold is a killer - unlike warm weather, which is a blessing.

Ogres and Dire Warnings

Recent AGW prognostications attempt to link every extreme weather event, volcano, or heat-wave - even out of season snow pack in North American mountains and June snow fall on the summit of Snowdon in the UK, as proof of global warming (disruption). As ludicrous as this obviously this it is going on - in shrill tones and a hectoring manner. It is quite reminiscent of pagan Roman reaction to the rise of Christianity.

Newsflash

The Lindzen paper, it seems, found that climate models are routinely exagerating climate sensitivity. It was accepted for publication on May 22nd and was written by Richard Lindzen of MIT and Song Choi of Seoul. All climate models rely on the hypothesis of feedback increasing the warming effect, the idea being that water vapour increases with rising temperatures so as to inhibit infrared cooling. Clouds become less reflective and cause increased solar absorption and therefore further and deeper amounts of warming.

An alarmist throat hold on information

This story can be seen at http://wattsupwiththat.com/2011/06/09/lindzen-on-getting-the-special-tre... .... (see also http://climateaudit.org/ June 10th) ... Professor Richard Lindzen is not flavour of the month with AGW alarmists. It seems he alarms the climate science fraternity and their political lackeys - inside science and not just in government.

All things green and wonderful

At http://bishophill.squarespace.com/blog/2011/6/6/koutsoyiannis-2011.html (or at simply www.bishop-hill.net June 6th) there is an interesting post by Doug Keenan on a paper by Koutsoyiannis which seems to show little empirical evidence of rising global temperatures and that the case supporting AGW rests almost entirely on computer simulation - but everybody knows that already. Basically, IPCC climate scientists make an assumption known as ARI - derived from the statistical concept of 'first order autoregression'.
