UC Berkeley physicist Richard Muller and others were looking at the so-called urban heat island effect -- the notion that because more urban temperature stations are included in global temperature data sets than are rural ones, the global average temperature was being skewed upward because these sites tend to retain more heat. Hence, global warming trends are exaggerated.
After reanalyzing all the data they now say:
"that the spurious contribution of urban heating to the global average, if present, is not a strong effect; this agrees with the conclusions in the literature that we cited previously." The literature they cite is the basis for the conclusion that Earth has been warming in an unnatural way during the period of human industrialization.
(Note that Krugman says it CO2 from the permafrost, but I think he means methane)
The scale and volume of the methane release has astonished the head of the Russian research team who has been surveying the seabed of the East Siberian Arctic Shelf off northern Russia for nearly 20 years.
I was not dreaming of a White Christmas and glad of it. I've still got fall cleanup work to do (15 large trees 150 feet from my magnetic front door, 50 leaf bags so far).
The month has been hassle free. Cool (but not cold) and dry, like nothing I've ever experienced. My father used to tell me about his easy winters in DC and the early spring but I've never seen anything like that (in New England). It will likely change soon here but right now I'm down with zero snow. And nothing in the latest forecast.
* 1/8 Still no snow and none in next week's rainy forecast. First time ever use of a leaf blower in January. I saw lots of shorts and tops down convertibles on the Blvd.

The last four years we have averaged an annual total exceeded the old record (because one of the years was so far above the old record that the other three high levels led to a higher average). However, it was warmer than 'average' because it snows more here in the middle of winter when it snows.
However, this year it is probably my warmest winter so far in the 23 years living here. We have had almost no snow (4.4 inches vs average of 20.4) and there is nothing on the ground (the last three years we had snow continually on the ground from the beginning of December through into March). HDDs so far: 2650; Normal: 3201. And the next three days are supposed to average over 45 degrees (F, of course).
The real answer of course is that weather is always acting funny (whereas climate normally is not). Weather operates on geologic time and we have no idea what's "normal" during out pitifully small lifetimes. Just as every generation of adults since Oog & Ogg has been lamenting the fact that the kids are going to hell in a handbasket, I'm sure Adam turned to Eve and said, "have you noticed that the weather here in Eden has really sucked lately?"
I remember in the late '50s my mother leaning over the proverbial garden fence and having a discussion with the next door neighbor (or in mom's case, neighbour) and saying, "the weather just hasn't been the same since they started that nuclear testing."
I'm just posting this from another thread. Seems more appropriate here.

Normally, yes. But this year we have the magnolia already.

You probably know of Suzy Favor Hamilton. And more recently Matt Tegenkamp and Chris Solinsky.
In my northern Badger garden, snowdrops, early crocus and a few Scilla sibiricas are blooming, the earliest in my memory, the hyacinths and tulips coming out, daffodils not quite yet. What is a pom? Should I feel honored or scream bloody murder ?
P.S. Once mump completes the list, I will re-post the alpabetized thing again, complete with corrections.
Well, Madison is a bit further south but here are a few measures of how unusual the weather it is. Despite the fact that we have the ten normally warmest days of the month to go, this March has (in comparison to the years since 1950):
1 Has four times as many Cooling Degree Days (excess of average daily temperature above 65) as the previous 62. 2 In only four years has April had more CDDs 3 The average temperature is already more than 8 degrees higher than the next highest March and if the forecast for the rest of the month holds, we will end up 12 degrees above the average and higher than the highest April over the period since 1950.
Well, weather is always acting funny, as gh says. However, there tends to be bounds, and the more days that are included the harder it is to get far away from a 'norm'. However, March in Madison is getting to a rather unusual level. Here is what I wrote on another thread:
Daisy posted the main part, so I will just add:
Such long periods of above normal also has the implication that maybe normal has changed. In fact, Madison has been warmer than average every month since October. We will almost certainly have the warmest heating season, less than 6000 HDDs, with the record before of 6395.

If you told Exxon or Lukoil that, in order to avoid wrecking the climate, they couldn't pump out their reserves, the value of their companies would plummet. John Fullerton, a former managing director at JP Morgan who now runs the Capital Institute, calculates that at today's market value, those 2,795 gigatons of carbon emissions are worth about $27 trillion. Which is to say, if you paid attention to the scientists and kept 80 percent of it underground, you'd be writing off $20 trillion in assets. The numbers aren't exact, of course, but that carbon bubble makes the housing bubble look small by comparison. It won't necessarily burst – we might well burn all that carbon, in which case investors will do fine. But if we do, the planet will crater. You can have a healthy fossil-fuel balance sheet, or a relatively healthy planet – but now that we know the numbers, it looks like you can't have both.
Read only the first paragraph of the linked Rolling Stone article; and that's enough for me to skip the rest and call the article BS. The article says "the odds of which occurring by simple chance were 3.7 x 10-99"; that shows zero understanding of statistics, and whoever makes such a claim has no business being making any scientific claims.
Daisy wrote:How about too colloquial? Presumably the writer is assuming his audience is not a bunch of statisticians.
In accordance with the forum rules, this is my last post on this matter: The statistical claim is bogus, and that's still putting it mildly. Presumably, the writer either assumes he can get away with it precisely because his audience is not familiar with statistics, or he actually believes his own BS claim.

The guy is actually a terrible economist, and in this context that is a non-trivial failing.
Specifically, How does he come up with the value figure of $27 trillion. You have to have some prices in the market. Now, if they produce somewhat less than the full amount the price might be a little bit higher, ... As such, the more you do not produce the higher the unit price and the total dollar value does not fall proportionately with the quantity (in some circumstances it will rise, as you have seen when supply is cut back 5% and the price increase by several times that 5%).
Add to this that it is not revenues that matter but revenues minus expenses. Thus, the net revenues will fall not nearly as fast as the total revenues because of the savings in cost, which are greatest on the marginal units, the ones that would go un-utilized.
When the most basic elements are not even a part of the discussion, the discussion is not worth much.

I learned something today! Since that's not what I learned at all, I went looking, and Wiki says
<<Henry of Huntingdon, the 12th-century chronicler, tells how Cnut set his throne by the sea shore and commanded the tide to halt and not wet his feet and robes. Yet "continuing to rise as usual [the tide] dashed over his feet and legs without respect to his royal person. Then the king leapt backwards, saying: 'Let all men know how empty and worthless is the power of kings, for there is none worthy of the name, but He whom heaven, earth, and sea obey by eternal laws.' He then hung his gold crown on a crucifix, and never wore it again "to the honour of God the almighty King". This incident is usually misrepresented by popular commentators and politicians as an example of Cnut's arrogance.>>
I'm sure that in school we learned that he thought he could. I've certainly remembered it that way for the last 50-odd years.
