Long ago Jonathan and I got some good traction out of a tangle of issues related to Global Warming slash Climate Change.  I think we are slated to renew or refresh our earlier exchanges.  I am going to poke in links to some he-said/he-saids from a few different threads at different times. One feature of the updated software is an automated 'sampling' of a link posted raw.  See below. 

So this blog entry will be kind of administrative-technical while being built and edited. I haven't figured out if Jonathan and I should impose some 'rules' going in, so your comment may be subject to arbitrary deletion before the field is ready for play. Fan notes included.

Adam, see what you think of the Yale Project on Climate Change Communication, especially the revealing map-based representations of opinion. You can drill and zoom down to state, county, district level to track data across a number of survey questions, where some of the answers are surprising. On some measures at least, the thing it is not found only in the UK, Quebec, Canada: Here's a snapshot of several maps which do not always show an expected Red State/Blue State pattern;

Plug my How To Get Where I Got book of books, Spencer Weart's The Discovery of Global Warming. Insert link to Amazon, Library link, and to the intro chapter of Weart's companion website to the book. Make sure you include a link to Ellen's mention of a book review. 

Bob Kolker's June 3 comment is a good hinge. What do we (J and I) think we know about the mechanism Bob sketches? What can we 'stipulate' or what can we agree on, for the sake of argument?

CO2 does  slow down the radiation of energy in the infra-red bandwith.  The question is to what degree  given that there are other systems that tend to diffuse and disperse heat (such as the Pacific Decadal Oscillation and El Nino, along with convection and the Coriolis Effect that moves warm are to the polar regions).  The scientific fact is that CO2 tends to absorb radiated energy in the infra red range.  That is NOT fabricated.  That is a matter of experimental fact. 

Please see http://scied.ucar.edu/carbon-dioxide-absorbs-and-re-emits-infrared-radiation

The issue is to what extent is the CO2 load of the atmosphere is slowing down heat radiation into space, when such absorbing or radiation occurs along with other heat dispersing processes.   

No denies that putting a blanket on, when it is cold slows down the rate at which one's body radiates heat.  Air is a poor heat conductor and the blanket traps air.  Also the blanket is warmed and radiates half its heat back to the source.  This produces a net slowing down of heat loss.  Heat loss still occurs (Second Law of Thermodynamics in operation)  but the rate of loss is affected. 

Tyndol and Arhenius  established the heat absorbing properties of CO2  in the late 19 th and early 20 th century.  Subsequent work has show the absorbtion to be the case and has measured it even more accurately than Tyndol and Arhenius.

How would you and I know if Plimer's views as presented in Heaven and Earth are correct, Peter?

I took Physical Geography many years ago and much of what I learned at University supported Plimer's views. 

Here's a critical 2009 review of Heaven and Earth, by Gus Van Horn at the Objective Standard:

Review: Heaven and Earth, by Ian Plimer

Quote

[...] Wouldn’t it be nice if a scientist wrote a book carefully documenting and explaining, in layman’s terms, the cases for and against man-made global warming? Then, we could determine for ourselves which claims are supported by evidence and logic.

Based on favorable publicity from conservative media and politicians, Ian Plimer’s Heaven and Earth: Global Warming, the Missing Science would appear to be just such a book. Plimer claims to present an “integrated scientific understanding of the environment,” and the book—chock-full of figures and graphs and containing more than 2,300 footnotes in its 504 pages—certainly makes a powerful first impression. Add to that EU President (and noted climate-change skeptic) Vaclav Klaus’s statement that the work is “clear, understandable, and very useful,” and a good grasp of the arguments for and against man-made global warming would seem to be just a few hundred pages away.

Unfortunately, Heaven and Earth utterly fails to deliver on its promise.

Spare a thought for the residents of New British Arizonalberta, who are not quite celebrating a weather milestone. I betcha wish you hadn't whinged about spring.

I testify to the truth of the bright red blob.

What explains the Winter weather in the southern hemi? We have been breaking historic record temperatures in SA, many parts below freezing.

Lack of data.

Our next five days here on Delmarva will be in the 90's. Odd bodkins. If climate ain't Man Made, how will Man change it? And if you have property on the water how will you sell it if sea levels are rising? Nuff said, or not? 

I think extreme temperatures are rising. Drought and / or excess rainfall are rising. I can see mankind migrating. I don't see the problem because we have always "migrated / moved." It might hurt personally or even generationally, but mankind has always moved to the best outcome. I may even learn the words to "O Canada."

Please convert your current Celsius temperature to Fahrenheit. I thought it was around a hundred F in SA.

Brant,

The IPCC needs to be defunded, dismantled and something new put it its place.

Hopefully something credible.

0 Celsius = 32 Fahrenheit, 100C = 212F, Peter. We get the intermittent Polar storms in winter which can average SA's lows at about -2C to about +3 in many regions. This July for a few days, they dropped to about -7 in a few places (-3 in Joburg), which are record lows. An unusual occurrence at this high altitude of normally dry, sunny winters in JHB are cloudy skies, like today, which brings the rare possibility of snow here, this I've seen a few times. Although the temperature is 10C presently, so maybe not tonight.

 

Approximate calculator: "If you want to convert Fahrenheit to Celsius, do the opposite: subtract 30 from the temperature in degrees Fahrenheit, and then divide by 2 to get the temperature in degrees Celsius".

If this shift continues, Canada can start sending polar bears to us while the Canadians enjoy warm climes.

How about we send you the Toronto Maple Leafs too?

Can the Maple Leafs play rugby? Cricket?

They have not won anything in hockey, rugby or cricket since 1967 lol, and even then they won plenty of times pre 1967 when there were 6 teams and got all the best players from Ontario!!!!!!!!!

Think the Leafs and the Dems have the two worst organizations around but I do think the Leafs are on the uptrend!!!

How are averages derived again, it’s been a while since class. Is 1.67 degrees a meaningful amount in the context of the average ? Standard deviation enthusiasts wanna know !
