Climate Alarmism: When Is This Bozo Going Down?

By Patrick J. Michaels and Paul C. “Chip” Knappenberger

Climate alarmism is like one of those pop-up Bozos. No matter how many times you bop it, up it springs. In fact, the only way to stop it, as most kids learn, is to deflate it. In this case, the air inside Bozo is your and my tax money.

Two scientific papers released last week combine for a powerful 1-2 haymaker, but, rest assured, Bozo springs eternal. The first says that human aerosol emissions are not that responsible for offsetting the warming influence of greenhouse gas emissions, while the second finds that the observed warming from human greenhouse gases is less than a lot of people think.

We aren’t at all surprised by the first result.  The cooling effect of sulphate particulates, which go into the air along with carbon dioxide when fossil…

A Lead Author of IPCC AR5 Downplays Importance of Climate Models

Richard Betts heads the Climate Impacts area of the UK Met Office. The first bullet point on his webpage under areas of expertise describes his work as a climate modeler. He was one of the lead authors of the IPCC’s 5th Assessment Report (WG2). On a recent thread at Andrew Montford’s BishopHill blog, Dr. Betts left a remarkable comment that downplayed the importance of climate models.

Dr. Betts originally left the Aug 22, 2014 at 5:38 PM comment on the It’s the Atlantic wot dunnit thread. Andrew found the comment so noteworthy he wrote a post about it. See the BishopHill post GCMs and public policy. In response to Andrew’s statement, “Once again this brings us back to the thorny question of whether a GCM is a suitable tool to inform public policy,” Richard Betts wrote:

Bish, as always I am slightly bemused over why you think GCMs…

Correlation Of The AMO With NH Temperatures

Further to my earlier post on the influence of the Atlantic Multidecadal Oscillation on Northern Hemisphere temperatures, it’s worth looking at the Woodfortrees graph below, which plots HADCRUT4 temperature anomalies for the NH, along with the AMO. Note that both series are detrended.

The correlation could hardly be closer. It does not take a genius to work out what will happen once the AMO turns back to its cold phase.

USHCN Monthly Temperature Adjustments

Guest Essay By Walter Dnes

There have been a number of posts on USHCN temperature adjustments, including 1, 2, 3, 4, 5 and 6. They have focused primarily on annual adjustments. Whilst looking into the USHCN adjustments, I noticed that each of the 12 months is adjusted differently. Here is a plot of average USHCN temperature adjustments, for each month plus the annual average, by year for 1970-2013:

UHI – worse than we thought

August 20, 2014

Originally posted on Watts Up With That?:

Remember when I measured the UHI in Reno, NV? It seems the normally alarmist “Climate Central” is just now getting around to recognizing UHI, but of course, they have to put in the obligatory disclaimer that it cannot possibly contribute to the global warming signal. Well, they are just flat wrong about that, but that’s what they are paid to say.

indianapolis_UHINew Study on Urban Heat Islands and Climate Change Shows Most Large U.S.Cities Getting Hotter Faster than Rural Areas

Since 1970, summer temperatures have been rising. While exact rates of warming differ between regions, most cities have been heating up faster than adjacent rural areas all across the United States.  The concrete and asphalt surfaces in city buildings, roads, and infrastructure hold more heat and release that heat more slowly than vegetation and organic surfaces. This is known as the Urban Heat Island (UHI) effect. Climate change…

The consensus was wrong

August 19, 2014

Originally posted on The IPCC Report:

In an article in the Guardian, Richard Tol wrote that “There are plenty of examples in history where everyone agreed and everyone was wrong”. He didn’t give examples there – perhaps he thought this was so well known that it wasn’t worth commenting on, or perhaps space was too limited.

Here are a few examples of where the consensus has turned out to be wrong (thanks to @Fastcomm, @intrepidwanders, @DerrickByford, @nmrqip and @Beautyon for suggesting many of these). More examples welcome! 
Yes, I know, these stories are all greatly oversimplified.

Copernicus, Galileo and the Sun. For some time after Copernicus wrote his book saying that the Earth goes round the Sun, most scientists continued to believe the opposite.

Ernst Chladni and meteorites. The consensus was that meteorites came from the earth, perhaps from volcanoes, until, around 1800, some nutter suggested they might come from outer space.
