As any weather aficionado can avow, Earth's most iconic weather record has long been the legendary all-time hottest temperature of 58°C (136.4°F) measured 90 years ago today at El Azizia, Libya on September 13, 1922. One hundred thirty six degrees! It's difficult to comprehend that heat like that could exist on our planet. For 90 years, no place on Earth has come close to beating the unbelievable 136 degree reading from Al Azizia, and for good reason--the record is simply not believable. But Earth's mightiest weather record has been officially cast down. Today, the official arbiter of Earth's weather records, the World Meteorological Organization (WMO), announced that the all-time heat record held for exactly 90 years by El Azizia in Libya "is invalid because of an error in recording the temperature." The WMO committee found five major problems with the measurement. Most seriously, the temperature was measured in a paved courtyard over a black, asphalt-like material by a new and inexperienced observer, not trained in the use of an unsuitable replacement instrument that could be easily misread. The observer improperly recorded the observation, which was consequently in error by about 7°C (12.6°F.) The new official highest hottest place on the planet is now Death Valley, California. A remarkable high temperature of 56.7°C (134°F) was measured there on 10 July 1913, at Greenland Ranch.

It was at this fort that the temperature of 58°C (136.4°F) was observed on Sept. 13, 1922 (used with permission from the family of Gen. Enrico Pezzi).

The story behind the overturning of Earth's most hallowed weather record
Today's announcement is the culmination of a 3-year research effort begun by wunderground weather historian, Christopher C. Burt. His blog post today, World Heat Record Overturned--A Personal Account, provides a fascinating detective story on how the record came to be cast down--and how the Libyan revolution of 2012 almost prevented this from happening.

Atlantic tropical update
Tropical Storm Nadine is recurving to the northwest and north well east of the Lesser Antilles Islands, on a track that would likely keep this storm far out at sea away from any land areas. However, Nadine may eventually threaten the Azores Islands or Newfoundland; the models are divided on how the steering currents will evolve next week, and we cannot be sure which way Nadine will go during the middle of next week.

The models predict that a trough of low pressure off the U.S. East Coast may serve as the focus for development of a non-tropical low pressure system on Sunday or Monday, but this low will likely form too far to the north to become a tropical storm. The GFS model has been predicting a tropical wave coming off the coast of Africa may develop next week, but has not been consistent with the timing or location of the development.

In the Western Pacific, Super Typhoon Sanba is an impressive top-end Category 4 storm with 155 mph winds, and is headed north-northwest towards a possible landfall in Korea early next week.

Given the importance of the new world record all-time high temperature, I'll leave this post up until Saturday afternoon, when I'll post an update on the tropics.

Free drinks for everyone
One night, a drunk comes stumbling into a bar and says to the bartender: "Drinks for all on me including you, bartender." So the bartender follows the mans orders and says: "That will be $36.50 please." The drunk says he has no money so the bartender slaps him around and throws him out.

The next night the same drunk comes in again and orders a drink for everyone in the bar including the bartender. Again the bartender follows instructions and again the drunk says he has no money. So the bartender slaps him around and throws him out.

On the third night he comes in, the drunk orders drinks for all except the bartender. "What, no drink for me?" replies the bartender. "Oh, no. You get violent when you drink.

A man had been out in the back woods for weeks, cutting logs. He was a bit scruffy and didn't smell very good. Finally he needed a break and came in to town for a few beers.

In the bar, he saw the local jock of the town's football team. He was bragging about his girlfriend and how she was lucky to have him for a boyfriend.

The lumberjack, after drinking six bottles of beer, was heard to say, "Buddy, if she went out with me, she'd never go out with you ever again."

To which the local jock replied, "Hey buddy, if she went out with you, she'd never go out with ANYONE ever again.

A man is in a bar and falling off his stool every couple of minutes. He is obviously drunk. So the bartender says to another man in the bar: "Why don't you be a good Samaritan and take him home."

The man takes the drunk out the door and to his car and he stumbles at least ten times. They drive along and the drunk points out his house to the man. He stops the car and the drunk stumbles up the steps to his house with the man.

The drunk's wife greets them at the door: "Why thank you for bringing him home for me, but where's his wheel chair?

bar jokes time


A pirate at the local bar discusses his past
A seaman meets a pirate in a bar, and talk turns to their adventures on the sea. The seaman notes that the pirate has a peg-leg, a hook, and an eye patch.

The seaman asks, "So, how did you end up with the peg-leg?" The pirate replies, "We were in a storm at sea, and I was swept overboard into a school of sharks. Just as my men were pulling me out, a shark bit my leg off."

"Wow!" said the seaman. "What about your hook"? "Well", replied the pirate, "We were boarding an enemy ship and were battling the other sailors with swords. One of the enemy cut my hand off."

"Incredible!" remarked the seaman. "How did you get the eye patch"? "A seagull dropping fell into my eye," replied the pirate.

"You lost your eye to a seagull dropping?," the sailor asked incredulously. "Well," said the pirate, "it was my first day with my hook

Blocking patterns: How global warming might have worsened US drought

Christian Science Monitor - September 14, 2012

Excerpt: As the summer of 2012 winds down, with drought and searing temperatures its hallmark for much of the continental United States, researchers are trying to get a better handle on the factors that contribute to the persistence of weather patterns responsible for the extremes. The immediate culprit: patterns of atmospheric flow that steer storms along a given path for weeks, heating and depriving some areas of needed rain while drenching others. Such blocking patterns are a global phenomena, a normal component of Earth's weather systems.

But some researchers suggest that global warming's influence on the Arctic and on the tropics can change circulation patterns in ways that keep blocking patterns in place longer than they otherwise might.

As researchers try to untangle the atmospheric influences behind persistent weather patterns, the Arctic and the tropics have come under increasing scrutiny.

The decline in summer sea ice, which this summer has reached a record low, deprived the Arctic Ocean of much of its reflective coat of white. This leaves more open ocean from which heat escapes back into the atmosphere in fall and winter. This tends to slow the jet stream's wind speeds and stretch its meanders north and south, according to researchers from Rutgers University and the University of Wisconsin at Madison.

i don't think so, maybe it could get a little stronger, but i dont see this developing before reaching the lesser antilles into a tropical depression.

I disagree. First of all, there has been persistence with this wave. Secondly, it is in an area favorable for development with an upper level anticyclone, and no SAL to deal with. I see this one being a Caribbean cruiser and something we should watch down the road. As I write this I see that convection is firing up with the wave.

Big time. As I wrote earlier, just the five largest oil companies alone--that is, not counting coal companies, nor any of the many oil companies not in the top five--earn $274 million in profit each day. Lists of the richest people in this country and in the world are packed with the names of those who've made fortunes in high-polluting fossil fuels. Meanwhile, there's not a single climate scientist on those lists. Care to guess why that is? :-\


That's an easy answer, coming from a resident of a state that has a former senator known as "king of pork" and a current senator that inherited oil company riches. Not to mention, the largest industry is coal mining. When mine jobs start at $25 plus an hour, it makes all those state jobs working for the DNR look pretty unappealing.

I haven't researched it, but it's a safe bet that there are lobbyists and lawyers making more money from the fossil fuel companies than is budgeted for climate research.

In my own local news, here's government at work.

In 2010, state officials decided the remodel and repair Dam Site 14 on New Creek in eastern WV. This dam serves as the water source for 15000 municipal customers in Keyser and New Creek, WV and in McCoole, MD.

There was an alternative source, in Limestone Dam near Keyser. However, in 2011 it was decided that Limestone Dam was to be breached and allowed to drain, as it was old, in need of reapir, and frankly not very safe either. The state DNR assisted and this was carried out.

Can anyone see the problem here? As we all know, this was a very dry, hot summer. The local water companies were depending on using water from New Creek to meet their demand. However, this creek was reduced to a trickle by July. Currently "trickle" would be an exageration. Dam site 14 is scheduled to be completed by late fall. Meanwhile... where's the water coming from???

Currently, a state of water emergency has been declared and customers are asked to refrain from outside watering, filling pools and to take 2 minutes less to shower (and who's timing that, I wonder?) Plans are being made to purchase water from surrounding communities to fill the water tanks until the dam is back on line.

Just goes to show what lack of planning and failing to realize the end result of your actions can achieve. Might be a lesson for some of us :)

Quoting HurrMichaelOrl:


I did some calculating based on the assertion that 40 trillion Liters of CO2 are released by man-made sources per day. This would equal approximately 1,412,580,518,400 (trillion) cubic feet of pure CO2 gas or 9.5965 cubic miles per day.

According to one online source, the total volume of the earth's atmosphere is 3,947,000,000 cubic miles.

Based on this, man is contributing about 1/411,295,785th of the total volume of the earth's atmosphere in CO2 emissions each day. How trace of an amount this is over time and its significance, I have no idea.


That trace amount has been raising atmospheric CO2 by approximately 2-3 ppm/yr. It would be 4-6 ppm/yr, however the oceans are not yet saturated and end up taking about half of our emissions.

You can look up the thermal characteristics of CO2, and then derived a graph based on concentration. Based on the graph, you can approximate how much additional power per area (watts/m^2) each additional amount of CO2 should cause.

That would only be an approximation, but it should give you the basic idea of what additional CO2 does to the Earth's IR profile. You can also do this for the other major greenhouse gases as well (water vapor, methane, etc.).

Of course, this doesn't how anything as a result of feedbacks, just the basic physics.

No....no there isn't.

For example, a single big oil company like Exxon typically makes enough money in a single quarter to fund our entire national science budget many times over. Not just the climate science portion, but the whole thing (NASA, NOAA, etc.). And that's just one company for one quarter.

There is no green energy company or climate science group or anything of that nature comes even close to the money involved with the fossil fuel industry. By that I mean there's a couple orders of magnitude difference.
