This paper describes a model that uses the basics of heat transfer to demonstrate than an increase in downwelling infrared radiation associated with increased CO2 reduces heat loss from the mixed layer of the ocean, causing the ocean to warm.

Along with Richard Lindzen joining the Cato Institute, Bengtsson now gives us two examples of ‘skeptical’ scientists becoming associated with political advocacy groups, and zero examples of mainstream climate scientists joining political organizations. Who is it that’s politicizing science? – Dana Nuccitelli

Michael Mann has had a paper on the Atlantic Multidecadal Oscillation (AMO) accepted by Geophysical Research Letters. The paper seeks to overturn the current understanding of the AMO. But on my reading of the paper Mann’s case is built on results that do not support his contentions.

Sea level tipping points are a popular CAGW/media theory, easily suggested by images of calving icebergs and summer meltwater rushing down Greenland moulins. But they are alarmist precautionary mitigation fantasies rather than remotely possible future scenarios on multi-centennial time scales.

. . . some scientists are mixing up their role with that of a climate activist. – Lennart Bengtsson
Professor Bengtsson’s persecution shows precisely why independent think-tanks such as the Global Warming Policy Foundation are essential. Truly, the old joke is becoming ever more true: what’s the opposite of diversity? University. – Matt Ridley

I have been put under such an enormous group pressure in recent days from all over the world that has become virtually unbearable to me. – Lennart Bengtsson

Why after 400 years of La Niña precedence, did periods of El Niños dominance start in the 20th century? And why did the two periods of strong El Niño dominance in the 20th century occur during a period when the CO2 concentration was rising? Is there a link between rising CO2 and the El Niño – La Niña balance? But if there is such a link, why did El Niños become less prevalent than La Niñas from 1941 to 1976 and be in balance after 1998?

Given the new information now available from the Southern Hemisphere, climate scientists must consider a larger role for natural climate variability in contributing to global temperature changes over the past millennium. – Kim Cobb

Regarding the Hockey Stick of IPCC 2001 evidence now indicates, in my view, that an IPCC Lead Author working with a small cohort of scientists, misrepresented the temperature record of the past 1000 years by (a) promoting his own result as the best estimate, (b) neglecting studies that contradicted his, and (c) amputating another’s result so as to eliminate conflicting data and limit any serious attempt to expose the real uncertainties of these data. – John Christy

The thing we’ve all forgotten is the heat storage of the ocean – it’s a thousand times greater than the atmosphere and the surface. – James Lovelock

Since the early 1990s, sea level rose at a mean rate of ~3.1 mm yr−1. However, over the last decade a slowdown of this rate, of about 30%, has been recorded. – Cazenave et al.

Science is not concerned only with things that we understand. The most exciting and creative parts of science are concerned with things that we are still struggling to understand. Wrong theories are not an impediment to the progress of science. They are a central part of the struggle. – Freeman Dyson

This past week, there have been several essays and one debate that provide some good perspectives on what we don’t know about climate change, and whether we should be alarmed.

Despite major investments in incorporating land cover in climate simulation models, much remains uncertain, especially concerning the influence of land-cover change on cloud cover and rain.
