U.S. experiences warmest 12-month period on record
Posted by: Dr. Jeff Masters, 06:09 PM GMT on Maj 08, 2012 +42
The past twelve months were the warmest twelve months in U.S. history, said NOAA's National Climatic Data Center (NCDC) on Tuesday, in their monthly "State of the Climate" report. Temperatures in the contiguous U.S. during May 2011 - April 2012 broke the previous record for warmest 12-month period, set November 1999 - October 2000, by 0.1°F. The past twelve months have featured America's 2nd warmest summer, 4th warmest winter, and warmest March on record. Twenty-two states were record warm for the 12-month period, and an additional nineteen states were top ten warm. NOAA said that the January - April 2012 period was also the warmest January - April period since record keeping began in 1895. The average temperature of 45.4°F during January - April 2012 was 5.4°F above the 20th century average for the period, and smashed the previous record set in 2006 by an unusually large margin--1.6°F.

Figure 2. The average temperature of 45.4°F during January - April 2012 was the warmest on record: 5.4°F above the 20th century average for the period, and was 1.6°F above the previous record set in 2006. January - April temperatures have been rising at about 1.9°F per century since 1895. Image credit: NOAA/NCDC.

April 2012: 3rd warmest on record
April 2012 was the third warmest April in the contiguous U.S. since record keeping began in 1895. Ten states had a top-ten warmest April, and no states were cooler than average. But what's really remarkable about April was that eight states--Illinois, Indiana, Kentucky, Michigan, Wisconsin, Ohio, Pennsylvania, and West Virginia--had average April temperatures cooler than their March temperatures, even though their April temperatures were still above the long-term average for the month. These statistics show just how remarkably warm March 2012 was. Most extreme was Illinois, where April 2012 temperatures ranked in the top 20% for warmest Aprils, yet were cooler than March 2012 temperatures.

Figure 4. NOAA's U.S. Climate Extremes Index (CEI) for January - April shows that 2012 had the most extreme weather on record.

Most extreme January - April on record
NOAA's U.S. Climate Extremes Index (CEI), an index that tracks the highest 10 percent and lowest 10 percent of extremes in temperature, precipitation, and drought, was 42% during the January-April period, over twice the average value, and the greatest on record. Remarkably, 82% of the contiguous U.S. had maximum temperatures that were in the warmest 10% historically, and 68% had warm minimum temperatures in the top 10%, with records going back to 1910. The previous records were 56% (2000) and 57% (1992) for maximum and minimum temperatures, respectively. The percentage area of the U.S. experiencing top-10% drought conditions during January - April was 19%, which was the 17th greatest since 1910. Extremes in precipitation as computed by the CEI were near average for the January - April period.

769. WatchingThisOne :-
Quoting, a paragraph:-

"I really hope Gundersen is full of crap and/or that they can get that #4 pool stabilized quickly. Or hurricanes will soon be the least of our worries."

It probably cant be done.
With the technology available to them at this stage of the operation, if they could have stabilized the situation after more than a year they would have done it by now, or at least tried.
All the evidence points to the fact that they cant do anything about it and are just siting there hoping and maybe waiting for somebody to come up with a solution.
The collapse of the structure may be, or is probably inevitable from an engineering point of view. Plus nobody has any experience of this kind of thing historically.
To describe their situation as "Dire," is hopelessly optermistic!

Keeper, everything appears to indicate that we may see our first ''threater'' a lot sooner than most would expect it to occur.
once we get down to 144 hr mark with the ghost system then flags will go up till then we still got time and lots of model runs yet to see its nothing but a tease right now

First haboob of the year in Arizona, it hit here in Tucson at about 245 local time. Fun thing to live through if your just watching and dont have a pool.

Quoting RTSplayer:


They will need a massive coordination.

Use helicopters specially rigged to carry loads of concrete and drop it on the pool, and of course, you need a large stable T-shaped object to tie a large cable or two chain on the structure. You will also need engineers to implode some parts of the building to seperate the spent fuel pool from the building as the concrete hardens. Then quickly pull it into the deep ocean and drown it. There, excess heat will always be carried away automatically, and the only concern is the life of the concrete being long enough to contain the fuel for enough half-lives to wear down the contamination.

Of course, nobody "wants" to do that, but it's a better option than risking the rods burn openly. If that happens, all of the work at the other buildings will have to be abandoned and you basically have a chain reaction that gets 4 or 5 times worse still...


About a year ago I suggested using tower cranes to first spry water on the things when they first got out of hand and later spray concrete from a mobile concrete pump.
They got round to the tower cranes and the water spray I note! From the photos.
My latest protegee is to construct a massive version of an bulldozer, a bit like a scaled up Caterpillar D9.
This would not be problem for them, as they have companies like Mitsubishi heavy industries, they could then demolish the structures and pick up the pieces.
One hell of a job but they could have made the super D9 by now. I just think they don't know what to do? So they do nothing.
A Japanese Scientist told me once that the inventiveness of the nation had been killed off by centuries of samurai genetic weeding out, IE if it thinks, kill it!

no it actually touches Florida in th 12Z ..the center just offshore..the 18Z bypasses Florida altogether and makes a hard right..

the 18Z and 00Z runs are not the best runs for the GFS as I have always been told on this blog..this storm is a long way out and if it materializes so you will see a lot of flip flop with the GFS

It shows a low pressure area in the same exact spot as the 12Z GFS did.

That's not very strong... GFS at that time is 1004... Still, since it's in the same spot I guess you could say the Euro sort of supports the idea of storm formation.

Here's a bit of a shocker:-

Scientists have found that the massive swirl of plastic waste known as the ‘Great Pacific Garbage Patch’ has increased a hundredfold since the early 1970s, which could spell major changes for California and other coastal states

And the link:-

some long time retired guy told me about a month ago, about 1946 and 57...now i just saw this march 2012 very early thoughts on this years tropical storm thing..this excerpt from crown weather..interesting he said the same thing as the guy I was talking to.......................So, I think the US East Coast and particularly the Gulf of Mexico are at risk this year from storms that develop relatively close to land rather than the long-tracked storms like Irene from last year. Additionally, the fact that 1910, 1921 and 1946 were years that had significant hurricanes impacting the Tampa area makes me kind of nervous. Additionally, the northern and western Caribbean may be at risk this year from any storms developing in-close (within 250-300 miles of the Lesser and Greater Antilles).

Go through some of these...it'll give you an idea of what its like when there is an active tropical cyclone.

Go through some of these before Danielle formed...it'll give you an idea of what its like on the blog during hurricane season with no active tropical cyclones for a while.

I think the cyclone has a good chance at forming. Where it goes is up in the air at this point, although the ECMWF/GFS do have a pretty strong trough at the time.
