The new hottest place on Earth: Death Valley, California
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.

A good way to estimate the impact on the worlds temperature would be to compare it with the eruption of mount Pinatubo in the phillipines. For reflective cooling to have a significant impact, the ejecta must contain large amount of SO2 and the eruption column must be high enough to penetrate the stratosphere. From what I read about the eruption yesterday, impact on the temperature should be neglegible as of now.
Don't tell that to one of my neighbors.
I just saw his little dog with its tongue hanging out the side of its mouth and he said he had all its teeth pulled because of "dog breath." Then the idiot complained because he had to pay $750 to get something out of its intestines. I don't want to walk past his house anymore because he makes me so sick. I would like his teeth all pulled out for bad breath!
I went from a V8 to a V4.
While I miss the quick acceleration am very happy with the cost of the car and mileage it gets an average 36-38 mph (and it is not a hybrid).
Hmmmm, I didn't take you for a social darwinist. OMG. jk
The amount of CO2 put in the air is staggering. Respiration contributes a tiny fraction. Burning one gallon of gasoline creates almost twenty pounds of CO2. Making concrete creates a lot of CO2, also, which surprised me.
Bold=name calling. Nice. Thanks for demonstrating exactly what I was talking about in one of my earlier posts.
(Btw, have you tried to put 4 kids in a small car? ever? and do you generally get 60" of snow during an average winter? 4 wheel drive comes in handy. & Do you think I like paying tons of money for gas? Very few cars/minivans that can seat 6-7 passengers get decent fuel economy and the ones that do, I can't afford.)
Meanwhile, the Blob down in the SW Caribbean about to come ashore in Costa Rica-Nicaragua around 12N-83W has been trying to get a nice groove on this morning. Don't know that it will have time to spin up because of the land interaction (Not worth noting for Atlantic development) but it could become a seed for E-Pac later on down the road......Again, no previous model support on this one.

Addmittedly, volume is a more accurate indicator of loss than area, but in terms of albido and reflecting solar energy that is now absorbed by the exposed arctic ocean, area works just fine.
(Arctic sea ice usually reaches its minimum area on the 2nd week of September)
This change isn't waiting for your grandchildren or the united nations.
Switching to methane that is 4 time more harmful than CO2 or puppy breath (would that make methane dinosaur farts?) is not a move in the improving things catagory.
You seem to be a frequent poster on the topic. Maybe you should cut back on your posts.
Since you bring it up, we know that the CO2 increase is from fossil fuels since the ratio of C14 is decreasing. C14 is a radioactive isotope of carbon. The carbon from fossil fuels is low in C14.
That is just plain ole' Nasty...
Yeah its Roddy White, my favorite player, he stuck the landing perfectly too. :)
So far its 2 votes for 5 and 1 vote for 6
you make your choices what you drive. If you have 4 children and need to drive a bigger vehicle then you will pay the price. Pretty simple, you are making a bigger footprint than most. This is the only way eventually we will ween ourselves off of these destructive emissions is by making it too expensive for people to place them into the air.
sometimesoftenusuallyalways leads to inadvertent misunderstandings and misinterpretations of scientific findings. Ideological blinders make for difficult navigation...There are scientists all around the world of many different political persuasions who have looked at the overwhelming evidence and come to the inescapable conclusions that a) the world is rapidly warming, b) CO2 is the culprit, and c) that CO2 is from us. To claim that all those scientists everywhere are engaged in a worldwide conspiracy merely to deprive Americans of their "freedoms" is absurd beyond almost all reasoning, and, frankly, pretty darned paranoid.
Living where you wish and living as you like is a freedom. Selfishly destroying the environment--and lying about doing so--isn't.
It's the place where the highest ever temperature was recorded on one day, that's it.
I like this post.
I like this post, too.
I occasionally like quite times like this. Times when bloggers start touching the subjects of history, social science and philosophy. And times when bloggers who convey their ideas, fears, and doubts are respectfully replied with posts that will leave you with points to ponder. It feels like we truly communicating with each other.
Part of the issue regarding fossil fuels is that government is trying to force the issue - like the ethanol requirements: because of the drought, corn production is way down this year, which historically would have caused issues on the world food market as it is, but with the ethanol boom, about 1/2 the corn produced this year will be turned into fuel. (Did you know that it takes, on average, a gallon of gas to produce a gallon of ethanol? That's working well.) What kind of policy requires citizens to burn FOOD for Fuel? It makes little sense. We will be seeing the worldwide reverberations from this policy soon - the riots happening in the MidEast will be joined with the suffering of people starving in countries that rely upon American corn, etc. due to the policies instituted by our government. Makes me wonder if the policies aren't in some way a backhanded way to fight the population boom. There are some in the administration who have been big on population control - John Holdren and Cass Sunstein come to mind - who knows? Although, in the US, we have just crossed the line where our birth rate does not keep up with the "replacement rate" - we are becoming very much like Europe in that way.
Quoting hydrus:
Hello Nea..The pendulum is swinging over in regards to the belief that global warming is real, albeit slowly. The thing that gets me the most is that there are people that still believe that it is some fantasy invented by the left to control governmental issues...What more then what is already happening does it take to convince these idiots that the Earth is not only warming, but doing so at an alarming rate. My conclusion is that they will put there interests first regardless of the scientifically proven facts until they can get everything they want for as long as possible, then say o.k. your right. By then they will have profited as much as they could under the circumstances knowing they lied to satisfy there agenda.
Name calling prevails.... so sad a discussion turns into exactely what it always does...
Ethanol is not for CO2. I suspect it increases CO2 emissions. Ethanol is for other types of pollution. Wikipedia:
"Oxygenate blending adds oxygen-bearing compounds such as MTBE, ETBE and ethanol. The presence of these oxygenates reduces the amount of carbon monoxide and unburned fuel in the exhaust gas. In many areas throughout the US, oxygenate blending is mandated by EPA regulations to reduce smog and other airborne pollutants. For example, in Southern California, fuel must contain 2% oxygen by weight, resulting in a mixture of 5.6% ethanol in gasoline. The resulting fuel is often known as reformulated gasoline (RFG) or oxygenated gasoline, or in the case of California, California reformulated gasoline. The federal requirement that RFG contain oxygen was dropped on 6 May 2006 because the industry had developed VOC-controlled RFG that did not need additional oxygen.[14]
"MTBE use is being phased out in some states due to issues with contamination of ground water. In some places, such as California, it is already banned. Ethanol and, to a lesser extent, the ethanol-derived ETBE are common replacements."
Gotcha, I read it and said..."what?".... thanks. Yes burf control.
Did anyone see the picture of starving polar bears in the Arctic (what's left of the ice) in yesterday's CNN?
I'm selfish? Seriously? At this point, I'm more concerned that the USA will be around for my kids because it didn't completely fail economically due to inept and destructive policies being either passed by a corrupt Congress or Executive Ordered by a President who chooses to bypass Congress completely. Excuse me for realizing that what is happening to our country financially is going to have more immediate impacts on my kids' futures than my driving an SUV for a few years is going to have.
It is also very hard to listen to those who scream the loudest about AGW and then watch them get into their jets/limos/hummers and take their "passion" seriously (Al Gore, pretty much any celebrity, Nancy Pelosi, et al...) or the science seriously.
