August 2012 was the globe's 4th warmest August on record, according to the National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC). NASA rated August 2012 the 6th warmest on record. August 2012 global land temperatures were the 2nd warmest on record, and global ocean temperatures were the 5th warmest on record. August 2012 was the 330th consecutive month with global temperatures warmer than the 20th century average; the last time global temperatures were below average was February 1985. Global satellite-measured temperatures in August for the lowest 8 km of the atmosphere were 3rd warmest in the 34-year record, according to the University of Alabama Huntsville (UAH). Wunderground's weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of August in his August 2012 Global Weather Extremes Summary.

Most areas of the world experienced much higher-than-average monthly temperatures, including much of Canada, Southeast Europe, and Western Asia. Central Russia was much cooler than average.

El Niño watch continues
Sea surface temperatures were at 0.5°C above average as of September 17 in the equatorial Pacific off the coast of South America, and have been near or above the 0.5°C above average--the threshold needed for a weak El Niño event--since the beginning of July. However, winds, pressures, and cloud cover over the region have not responded in the fashion typically associated with an El Niño, and NOAA's Climate Prediction Center (CPC) classified conditions as being neutral in their September 6 El Niño discussion. They continued their El Niño watch, and gave a 69% chance that an El Niño event will be in place by the end of September. El Niño conditions tend to decrease Atlantic hurricane activity, by increasing wind shear over the tropical Atlantic. Wind shear has been close to average over the tropical Atlantic since the beginning of hurricane season in June. However, the past few runs of the GFS model have predicted a significant rise in wind shear over the Caribbean and tropical Atlantic by early October, which may represent El Niño finally beginning to kick in and affect the atmospheric circulation over the Atlantic.

Arctic sea ice falls to all-time record low during August
August 2012 Arctic sea ice extent reached its lowest August extent in the 35-year satellite record, according to the National Snow and Ice Data Center (NSIDC). The new sea ice record was set on August 26, a full three weeks before the usual end of the melting season. Every major scientific institution that tracks Arctic sea ice agrees that new records for low ice area, extent, and volume have been set (see the comprehensive collection of sea ice graphs here.) Satellite records of sea ice extent date back to 1979, though a 2011 study by Kinnard et al. shows that the Arctic hasn't seen a melt like this for at least 1,450 years (see a more detailed article on this over at skepticalscience.com.) The latest September 18, 2012 extent of 3.5 million square kilometers is approximately a 50% reduction in the area of Arctic covered by sea ice, compared to the average from 1979 - 2000. The amount of open ocean exposed this September compared to September 1980 is about 43% of the size of the contiguous United States. The ice extent is close to its minimum for the year, and should start in increase within the next week or two, but that open water over the Arctic will provide a significant amount of heat and moisture to the atmosphere over the next few months that will significantly alter weather patterns. One possible impact may be an increase in the intensity and duration of extreme weather events during fall and winter.

Nadine approaching the Azores
Long-lived Tropical Storm Nadine is headed northeastwards on a track that will bring the storm close to the Azores Islands on Wednesday and Thursday. A tropical storm watch has been posted for the islands of Flores and Corvo in the northwestern Azores. Steering currents for Nadine are expected to weaken on Wednesday, and the storm will move slowly and erratically for many days in the Central Atlantic late this week and early next week. On Friday, Nadine will become tangled up with an upper-level low pressure system, and the storm may partially or fully convert to an extratropical storm. By this weekend, the GFS and ECMWF models predict Nadine will move southwestward over warmer waters, and it could become fully tropical again.

Elsewhere in the Atlantic, thunderstorm activity associated with a tropical wave that moved through the Lesser Antilles Islands yesterday (92L) has diminished, and this wave is no longer a threat to develop. None of the reliable computers models is showing development of a new tropical cyclone in the Atlantic through September 24.

..................Scientists have Found a way to make Liquids levitate!!...Scientists used two small speakers to generate sound waves, whose levels are above what we can hear.

Pressure from the sound waves cancel the effect of gravity, allowing light objects to levitate.

Researchers hope to use this technology to develop amorphous drugs that will allow patients to take smaller doses with fewer side effects.

Going Batty??..................A Manatee County family is battling a bat problem.

Leo and Joan Masucci, who live in Ellenton's Colony Cove, said hundreds of bats recently moved into their home, causing major problems for them.

"You can’t imagine how stressful this has been for us," Joan Masucci said.
The couple said that at first, they didn't even realize the bats were there. Then, after a few months, they started smelling a rotten odor.

"I thought there was a dead animal under the house," Leo Masucci said.

The bats were not visible to the homeowners because they were up above the ceiling. They were able to get into the home through a small hole in the back of the house.

The bats chewed through the drywall, shredded the duct work and left feces all over, which created the terrible odor.

Despite learning about the problem, the couple couldn’t do anything about it because of what time of the year it was.

"From April 15 to Aug. 15, bats here in Florida are protected," said Christy Norris, who works with Nuisance Wildlife Removal. "There’s a maternity season, and you can’t exclude them in any way shape or form during that time."

So the couple waited until after the protection date to move forward. However, now they're dealing with another problem.

To repair all of the damage done to their home, it's going to cost an estimated $15,000.

The couple thought their homeowner’s insurance would pay for it, but they’ve been told the repairs are not covered.

Bay News 9 contacted the homeowner's insurance company, American Traditions. A representative said the company is aware of the problem and is looking into it.

The homeowners fear for their health and said that because of that, along with the smell and damages, they've moved out.

The Masuccis said they have decided to pay for the repairs themselves so they can return home soon. However, they're still trying to convince their insurance company to cover the costs.

Nuisance Wildlife Removal and another team are now working on the home.

The couple says this is something they never thought was possible and now they're warning others.

"I’d like people to know to make sure their homes are checked and that holes are filled in," Joan Masucci said. "There are a lot of bats looking to nest. I don’t want anyone else to have this same problem."

From 'The Price of Oil':

Fracking ... Its Not Actually About Sex

By Andy Rowell on Sep 18, 2012

Fracking may be causing protests from America to Europe, but in South Africa, the latest country to lift a ban on the activity, many of the locals don’t even know what the practice entails.



Earlier this month, South Africa lifted a 2011 ban on shale gas exploration and fracking in its semi-arid ecologically-sensitive Karoo region, known for its rugged, rural beauty.

In April last year the country stopped accepting exploration applications over environmental concerns regarding fracking, especially in relation to drinking water.

But the country has buckled to industry lobbying led by oil giant Shell and overturned the moratorium. The lifting of the drilling ban is expected to result in a scramble by the oil majors for reserves seen as the fifth largest in the world.

The government has also announced that it would “hold a series of public consultation with interested and affected stakeholders to provide further details.”

It also needs to inform people what fracking actually is.

Despite the media coverage of the lifting of the moratorium, in a recent poll in South Africa almost 2 in 3 (62 per cent) said they had not heard of the technique before.

Of those who claimed they had heard of fracking, only 25 per cent thought it referred to a method of extracting natural gas.

Some 34 per cent thought it was a way to protect against sunburn.

And a further 26 per cent believed it was a type of sexual activity.

However, when people were explained what fracking actually was, some 84 per cent of the respondents were against it.

About Fracking

Fracking, technically known as hydraulic fracturing, is a highly water-intensive and relatively new process that injects millions of gallons of water mixed with sand and chemicals thousands of feet beneath the ground to obtain previously hard-to-reach oil and gas deposits. This polluting process is:

• Endangering our drinking water supplies
• Polluting our air
• Releasing dangerous levels of methane, a potent greenhouse gas that can migrate into nearby wells, causing home explosions
• Negatively impacting agricultural communities
• Perpetuating our addiction to fossil fuels

Learn more about the risks fracking imposes on our water, air and communities.

Yeah, I've seen a recent spate of articles (and forum comments) extolling the virtues of natural gas as a replacement for coal. It's true that natural gas only releases about half the CO2 of coal when it's burned--but that's still a substantial amount. Natural gas, too, comes with the very high risk of heavy methane leaks--and methane is far more powerful a greenhouse gas than is CO2. Also, as your article points out, there are the environmentally contaminating effects of fracking--and we won't even discuss the numerous earthquakes that have been proven to be related to the practice.

Almost all of the cheerleading for and celebrating of the wonders of natural gas I've seen has come from the natural gas industry. But gas isn't a panacea, and it surely won't get us out of this climate change mess in which we find ourselves. After all, we've not exchanged a non-renewable greenhouse gas-producing fossil fuel for a clean and safe alternative energy; we've merely traded in one non-renewable greenhouse gas-producing fossil fuel for another non-renewable greenhouse gas-producing fossil fuel.

Wont a battery freeze solid at that temp? We went for three months and never turned the engines off. We also used them for heat, generating electricity etc. Big fuel tanks!



Alaska gets temps like -60, but they take their batteries out and plug them into a battery wrap. Needless to say, we didn't have anything like that in Kansas.

I can't imagine sending anyone, less kids out at -60. At -45 we were dersed in coats with built in heaters and air warmers. We were outside for hours on the ice but still. -60 is Deadly


It was deadly. I was teaching and all the teachers were furious as we tried to warm up kids, furious at parents who still had their children walking to school in temperatures they wouldn't walk in. I had to call in the second day because my van's battery had died. My husband refused to buy a new one until it was over because it would only have died the next night. Many teachers were out for the same reason, couldn't get to work. And yet parents sent their kids out to walk to school. The little girl the man picked up was dressed in a skirt! The man threatened to sue the school for endangerment of children and to send it over the AP news.

Kansas hit -60 for several days when I lived there in the 80s. School was not cancelled the first two days and there were no school buses, kids walked or parents dropped their kids off. Car batteries died in that cold temp, died as in you needed a new battery. There were warnings about how fast frostbite could happen and not to be outside for more than a few minutes at most. A man picked up a kindergartner who was walking and brought her into the principal's office. He told them to go ahead and call the police because he wanted the story to go international about a school that had kids walking blocks in temps where such severe warnings were. School was closed the next two days until it warmed up to acceptable degrees.

I have a question about ACE values for storms, when the systems become extratropical but still have wind speeds greater than 39 mph are these wind speeds still used when calculating the ACE value of the storm?

I know when the systems are subtropical the wind speeds are not included in the ACE calculation so I'm guessing this is also true for when/if the storms are extratropical, but I'm not sure.....

It's not included. Accumulated Cyclone Energy is calculated for only tropical storms at 6-hour intervals.

That's the dirty little secret that the carbon fear mongers hope you don't notice.


True, this is one of the main issues for solar power currently. However, in the long term it is hoped that car batteries can be utilised to store the power in a 'smart-grid' system and the manufacturing will obviously have to be done closer to home.

However, this idea is a long way off being practical and is indeed one of the main issues of solar power. I think I've read somewhere that solar power is the third most 'dirty' fuel if the emissions from making batteries are taken into account, but I'm not sure if that also included the emissions for building new fossil fuel plants and maintaining them etc.

But that is why you can't have a direct replacement with one renewable energy to a fossil fuel - they are too reliant on other conditions (e.g. weather/time of day), so you need to have a range of renewable energies in order for them to deliver reliable power output.

I am glad that reblob moved across the state south of Okeechobee Lake last night, it is already overfull. Army Corps will open the locks and start dumping water out the St. Lucie and Caloosahatchee Rivers.The St.Lucie is already in its final death throes, this new bigger dump will seal the deal.

It would be cool if Nadine became extratropical, then tropical again. That's a possibility, right?

Also, recent typhoons are maintaining strong wind speeds in the mid-latitudes. Are Western Pacific MSLP patterns similar to those of the Atlantic?


The western Pacific tends to be similar, following the same thematic pattern of a persistent ridge over the central portion of the basin. However, because of the vast reservoir of warm water that portion of the world has to offer, tropical cyclones forming in the region have the tendency to be much larger (often labeled "monsoon depressions" because of the large nature of their circulations)" than an Atlantic tropical cyclone. The pressure gradient also tends to be greater with western Pacific storms (again due to the warm water), so the typical wind/pressure relationship found in the Atlantic may not apply.

Aye. Satellite imagery suggests that it is well-defined.


Well, it's not in the MDR and the Gulf like 92/93L were/are, so I say it becomes a category 5 in about a week. It's such a slave to trends; and Michael hit a sweet spot around there.

It would be cool if Nadine became extratropical, then tropical again. That's a possibility, right?

We should have switched to natural gas for vehicles and power plants a long time ago. The issue with solar is battery banks. The large, deep cycle batteries needed for solar systems to store power are mostly manufactured in China or Korea under some of the most polluting conditions in the world. They have to be changed out and disposed of every 2-3 years. Even with recycling, a mass switch to solar power will create a huge hazardous waste problem. Until we improve battery types and prices, solar is dead in the water.

That's the dirty little secret that the carbon fear mongers hope you don't notice.

You can start to see some circulation with the central Atlantic low towards the end:

Thanks for your explanation! I don't know about tropical cyclones that well. I hope you explain other things about TCs if I don't know.


I'd be happy to oblige anytime, so feel free to ask.

Mean sea level pressure. In a typical El Nino, we would expect to see lower pressures in the mid-latitudes, with higher pressures in the tropics. The higher pressure produce strong trade winds over the MDR breeding grounds, which generates shear and sinking air.

What does MSLP stand for?


Mean sea level pressure. In a typical El Nino, we would expect to see lower pressures in the mid-latitudes, with higher pressures in the tropics. The higher pressure produce strong trade winds over the MDR breeding grounds, which generates shear and sinking air. The stronger Bermuda-Azores ridge over the central Atlantic is one of the key reasons why many disturbances/cyclones failed to significantly develop in the MDR, some notable examples being Ernesto, Helene, and Isaac.

Easy. El Nino has been altering the MSLP pattern since the beginning of the season.
