On Thursday morning, July 12, 2012 the low temperature at Death Valley, California dropped to just 107°F (41.7°C), after hitting a high of 128° (53.3°C) the previous day. Not only does the morning low temperature tie a record for the world's warmest low temperature ever recorded, the average temperature of 117.5°F is the world's warmest 24-hour temperature on record. According to weather records researcher Maximiliano Herrera, the only other place in the world to record a 107°F low temperature was Khasab Airport in the desert nation of Oman on June 27, 2012. The previous U.S. record high minimum temperature may be a 103°F (39.4°C) observed in Death Valley, California in 1970. The NWS lists a July 5, 1918 low temperature of 110°F as the official highest minimum temperature recorded in Death Valley. This temperature is disputed by Mr. Herrera, who says the temperature that night was not monitored and passed from 60°F to 110°F then to 60°F again.

Wednesday's high of 128°F (53.3°C) was the 10th hottest temperature in U.S. history, and the hottest temperature measured in the U.S. since July 18, 2009, when Death Valley recorded another 128° reading. The only hotter temperatures in U.S. history were all measured at Death Valley, the most recent one being the 129° measured on July 6, 2007. The all-time high for Death Valley is the 134° reading of July 10, 1913.

Temperatures have cooled considerably at Death Valley over the weekend, and the forecast for Monday calls for for a downright chilly high of just 110°. That's sure to be a disappointment for the ultramarathoners in the grueling Badwater Ultramarathon, which begins Monday in Death Valley. Covering 135 miles (217km) non-stop from Death Valley to Mt. Whitney, CA, it is the most demanding and extreme running race offered anywhere on the planet. I'm sure they would have liked to have had the distinction of running their race last Wednesday and Thursday, during the hottest 24-hour period ever recorded on the planet!

I was pleased to see this happen, but the area of the satellite photo I sent to this blog today, showing thousands of square miles of ship pollution effects, is outside of the regulated area. That pollution, however, WILL blow onshore in the US in a few days and cause thousands of people asthma, etc; even death.


Totally agree. Improving harbor air pollution is atleast one step in the right direction. Have to wonder if lowest grades aren't being used more offshore since money will be lost using the more expensive stuff near shore though.

Usually it is small scale like cloud seeding to make it snow over a certain area so no it shouldn't contribute to climate change.

Second, what is with all the bickering on contrails over the Pacific. Sheesh. At least make it a formal argument. We still have Fabio and Khanun in the WPac.

Third, what will Fabio's winds be at the next advisory? My guess is that it will be 65-70 mph.

60-65mph imo

why should ship smoke make a cloud?
Besides the fact that there are not enough ships out there to make that much smoke.
The smoke would tend either to be in a track and dissipate or form smog.
not a massive cloud deck

The largest component of hydrocarbon exhaust is water vapor.

There are MANY more ships than you think out there. And wxmod isn't going on about the cloud deck (which is normal), but the lines of clouds to the west of that.

Dude. You just went from "odd" to "something past crazy". Now you claim that this ONE alleged example of weather modification will cause "thousands" of people to get asthma and some of those will die?

Wow. Just wow. Please look up some info about asthma in a reputable medical journal or textbook. And while you are at it, please refrain from posting about stuff that you know absolutely jack squat about.

The Pacific is most likely unintentional geoengineering through pollution. But intention weather modification isn't tin hat stuff..it's a huge business. If you had enough money you could hire a company to modify your weather..this is just one of many companies available for hire.. Now it is mostly farmers paying but before the recession hit the govt was paying for their services, especially in the midwest. Not asking anyone to put on a hat, just take off the blind fold.


Welcome to Weather Modification Incorporated..

About Us

Now, more than ever, the worldwide need for solutions to atmospheric necessities such as water resource management and environmental quality monitoring, is critical. With nearly a half-century of successful programs, our experience speaks for itself.

Let us help you better manage your atmospheric and water resources.


Introduction of Seeding Agents

Water resources are increasingly taxed by exploding demand and continued population growth. The world's population is projected to grow over 40% in the next 45 years.

Weather modification, commonly known as cloud seeding, is the application of scientific technology that can enhance a cloud's ability to produce precipitation. Weather Modification, Inc., is on the forefront of scientific technology to maximize water availability worldwide. Application of scientific concepts and extensive scientific experimentation has proven that cloud seeding increases the amount of precipitation.
Cloud seeding useful in the following applications:

Increasing Precipitation

Mitigating Hail Damage

Dispersing Fog
Enlist our team of cloud seeding experts.

Whether you are looking for a small operation or a full program, Weather Modification, Inc. can ensure your cloud seeding project runs smoothly. From Federal Aviation Administration (FAA) approved aircraft installations, configured for aerial cloud seeding and cloud physics, to ground-based seeding equipment and training, Weather Modification, Inc., has the equipment, experience and knowledge you need.
Types of Cloud Seeding:

Aerial Cloud Seeding
Ground-Based Cloud Seeding

Here's a CA govt document about how cloud seeding has been continuous since like the 1950s.. I think NV lost it's funding in 2008..

I hear thunder:) Off to play.

What does that prove? Just that a senator got a wild hair and decided to start a bill to establish a weather modification board. It doesn't say anything about ongoing activities (or lack thereof), current research (or lack thereof), or any planned wxmod initiatives (or lack thereof).

Based on your logic, if a committee was established to study faster-than-light travel, that must mean that we already have FTL travel and have already started colonizing other solar systems.

Thanks for posting this. There are dozens of articles about shipping pollution. It's a HUGE problem. Shipping and air travel are geoengineering the planet every day! A lot of it is unintentional, but it can be done intentionally by governments, or private industrialists whose agenda is diverse and includes weather modification to increase water to their pet projects, like power dams and city water supplies. There are thousands of documents online that show what is spent by power and water companies each year for weather modification.


pollution is not wxmod.
In that case, UPS would be a massive wx modifier
Although pollution may affect climate, wxmod is a totally different thing


basically
pollution = climate modification
weather modification = just that, wx modification, nothing to do with climate

maybe you should pore over thousands of articles on climate and weather before commenting on this blog...

I see a lot of research, and nothing about sheeting the whole pacific in cirrus.

Dont get me wrong, weather modification is occuring, but nowhere near to teh extent to which you make it out to be, mistaking plane contrails, ship, and ocean cloud decks for "massive wxmod undertakings"
Next you will say they have kept all the hurricanes away from the US since that bill was introduced in 2005 by weather mod so we never had a repeat

(beyond the fact that the bill wasnt succesful)

There are papers.. & watch the speeds..those are ships & their pollution is pretty much unregulated. For the most part they use the bottom of the barrel dirtiest fuel.

Not only do they provide 4-5% of CO2 worldwide..

Exhaust emissions from ships are considered to be a significant source of air pollution, with 18 to 30 percent of all nitrogen oxide and 9 percent of sulphur oxide pollution.[12] "By 2010, up to 40 percent of air pollution over land could come from ships."[13] Sulfur in the air creates acid rain which damages crops and buildings. When inhaled the sulfur is known to cause respiratory problems and even increase the risk of a heart attack.[13] According to Irene Blooming, a spokeswoman for the European environmental coalition Seas at Risk, the fuel used in oil tankers and container ships is high in sulfur and cheaper to buy compared to the fuel used for domestic land use. "A ship lets out around 50 times more sulfur than a lorry per metric tonne of cargo carried."[13] Cities in the U.S. like Long Beach, Los Angeles, Houston, Galveston, and Pittsburgh see some of the heaviest shipping traffic in the nation and have left local officials desperately trying to clean up the air.[14] Increasing trade between the U.S. and China is helping to increase the number of vessels navigating the Pacific and exacerbating many of the environmental problems. To maintain the level of growth China is currently experiencing, large amounts of grain are being shipped to China by the boat load. The number of voyages are expected to continue increasing.[15]

WHILE THE PRIMARY THREAT WILL BE CLOUD TO GROUND LIGHTNING...STORMS
FROM BREVARD AND OSCEOLA COUNTIES NORTHWARD WILL BE CAPABLE OF
PRODUCING STRONG WIND GUSTS AND SMALL HAIL. REMEMBER...LIGHTNING CAN
STRIKE MANY MILES OUTSIDE OF ITS PARENT STORM...EVEN IF NO CLOUDS
ARE OVERHEAD. IF THUNDER IS HEARD...CEASE OUTDOOR ACTIVITIES AND
MOVE INDOORS IMMEDIATELY.

.FLOOD IMPACT...
NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS WILL DEVELOP ACROSS
EAST CENTRAL FLORIDA TODAY. STORM MOTION WILL BE VARIABLE IN
DIRECTION AND BETWEEN 5 AND 10 MPH. DUE TO THEIR SLOW
MOVEMENT...THEY WILL PRODUCE LOCALIZED HEAVY RAIN WHICH MAY CAUSE
LOW-LYING AND POOR DRAINAGE AREAS TO FLOOD.

The parts I disagree with on your statement are that they are "changing worldwide weather", and "just the facts".

While they could be theoretically be changing the weather, there are other things that we as a species have done that changes the weather much more drastically. Between our propensity to pave over everything, cut down trees, and burn forests to clear land, some intermittent high clouds are not going to make a gigantic impact.

Secondly, showing a set of satellite photos and hypothesizing all of these things from them is far from a proper burden of truth.
