U.S. experiences warmest 12-month period on record
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.

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.

Thanks anyway but ameister got me going!
Thanks for posting that! I wasn't on last night to see that message.
It's fascinating that anthropogenic global warming was well understood by the 1930's!

Operation Fast and Furious!!!!
The storm actually looks to be avoiding TX
So we are not supposed to question ideas? No one was insulting Dr. Masters! Im through with it! And you wonder why people groan when we see a drought map posted in the blog. I'm out!
(my sorry attempt at humor)
Yep. It's moving south east.
This one is intense

I thought it was funny. :/
Look at it this way, all weather freaks have a sense of humor only understood by other weather freaks
learn to spell, friek. :)
Thanks in advance for reading.

Hey, Kori? I recognize you, but who is the guys in the blue shirt and stripes standing next to you on the right?
huh? i did its freak
Small yet intense
Nice...these images are a bit blurry though
I like that!
Sorry, but I had the distinct impression that you were implying that the photo was faked.
Yeah, my phone camera isn't the greatest.
Very Nice!!!

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST TEXAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT
DAYTIME HEATING AND AN APPROACHING UPPER LEVEL DISTURBANCE WILL
HELP GENERATE SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING
ALONG A SEA BREEZE BOUNDARY JUST INLAND. A BROAD AREA OF WIDELY
SCATTERED THUNDERSTORMS MAY BE POSSIBLE TONIGHT AS AN UPPER LEVEL
DISTURBANCE MOVES ACROSS THE AREA. SOME STORMS COULD BE STRONG BUT
NOT EXPECTED TO BE SEVERE.
.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY
AN UPPER LEVEL LOW IS EXPECTED TO MOVE INTO TEXAS ON FRIDAY.
MOISTURE IS EXPECTED TO INCREASE THURSDAY INTO FRIDAY AS THE
SYSTEM APPROACHES WITH INCREASING LIFT. THUNDERSTORMS ARE EXPECTED
THURSDAY NIGHT THROUGH MUCH OF FRIDAY. THE MAIN THREATS WILL BE
HEAVY RAINFALL ACROSS THE AREA. THIS TIME PERIOD WILL BE MONITORED
FOR A FLOOD WATCH. THE UPPER LEVEL LOW WILL BE SLOW TO MOVE OUT OF
THE AREA AND RAIN CHANCES MAY CONTINUE INTO THE WEEKEND.
Reread his comment...its a joke.
no problem
Looks like a line we have forming in la
Right:-
"1" http://en.wikipedia.org/wiki/Calculus
"2" http://en.wikipedia.org/wiki/Logarithm
"3"http://en.wikipedia.org/wiki/Slide_rule
All means of calculating that we had to use before the invention of electronic calculators, the first of which I got in about 1970.
Without calculus probably very little of today's modern technology could exist including a lot of weather predictions.
PS I'm so glad we have computers now it saves so much time!
One of the changes that went through well in my book.
Lol. Yeah we're special that way. Just had some break up over me and reform over Louisiana. :)

A network of ultra-conservative groups is ramping up an offensive on multiple fronts to turn the American public against wind farms and Barack Obama's energy agenda.
A number of rightwing organisations, including Americans for Prosperity, which is funded by the billionaire Koch brothers, are attacking Obama for his support for solar and wind power. The American Legislative Exchange Council (Alec), which also has financial links to the Kochs, has drafted bills to overturn state laws promoting wind energy.
Now a confidential strategy memo seen by the Guardian advises using "subversion" to build a national movement of wind farm protesters.

Oh I'm glad too
What's up w115? Hopefully you'll get your wish!
Hey Nigel it seems you've been getting poured on lately.Mind sending some up to us? :).
I think the credit for that goes to Dr. James Hansen who testified in Congress in 1988 when Gore was still a Senator from Tennesee.
Rather than debate this anymore, might I suggest that you read this book?
Yes what I meant was gore supported it and then promoted the science I knew Hansen presented it to congress
Criminals, they ought to be locked up. These are dangerous people.

1) CO2 concentrations dont just change because they want to change. There is a reason behind it. Over long geologic timescales, this changes for many reasons... ocean uptake an release, weathering of land material, changes in flora concentrations, to name just a few.
2) We know that humans are emitting massive amounts of carbon, more than the known natural carbon sinks in the environment.
3) Carbon isotopes are different between natural carbon and carbon that comes from the burning of ancient fossil fuels. CO2 in the air has been shown to be coming from fossil fuel burning.
4) The carbon isotope ratios found in some plants and acidity of the oceans have been changing, indicating that they are doing more than expected in trying to take up the extra CO2 in the atmosphere.
5) Even ignoring all of that, your logic is shaky. We understand that smoking greatly increases changes for lung cancer, but lung cancer has occurred before cigarettes. Those two facts are not dissonant.
It has been shown that anywhere from roughly 75-125% of the current warming is due to man's activities. It may not all be man's fault, or it may be entirely man's fault with us reversing a natural cooling trend. Either way, the affect is not remotely trivial.
Nope. And even if so, not remotely relevant to anything.
Got a picture with Marty Pope, I see. We work with him almost daily... unless the Pearl River dries up.

It's named Clearwater for a reason...
Sea Surface Temperatures in the East Atlantic are cooler than in 2011...other than that, 2012 wins.
2010 beats both years.
The eastern Caribbean is getting much more than they wanted due to a persistent trough over the said area...i'm sure they would be will to give some or all the rain they are now getting for some dry weather
Another boring evening in Hillsborough...Man, I want some rain...
But the Philadelphia Flyers SCOOOOOOORE!!!!
