Fourth warmest May on record
The globe recorded its fourth warmest May on record, according to the National Climatic Data Center. The period January - May tied with 2003 as the sixth warmest such period on record. Global temperature records go back to 1880.
A warm and wet May for the U.S.
For the contiguous U.S., May temperatures were the 24th warmest in the 115-year record, according to the National Climatic Data Center. The Southeast region experienced its second wettest May in 115-years of record-keeping. In contrast, the West North Central region had their sixth driest May. Both Florida (9.86 inches) and Arkansas (10.91 inches) experienced their all-time wettest May. The last time Florida saw a record wet May was in 1976 when 9.15 inches of precipitation fell. Arkansas experienced its last record wet May in 1930 when 10.07 inches of precipitation fell. U.S. tornado activity was below average in May, according to NOAA's Storm Prediction Center.
On June 9, 2009, 14% of the contiguous United States was in moderate-to-exceptional drought. This is a drop from the 19% figure observed at the beginning of the year. The amount of the U.S. in the highest levels of drought, extreme to exceptional, decreased from 2.6% on May 12 to 1.5% on June 9. These extreme drought regions were in South Texas.
El Niño watch issued
NOAA's Climate Prediction Center issued an El Niño Watch last week, saying "that conditions are favorable for a transition from neutral to El Niño conditions during June - August 2009". The pattern of changes in surface winds, upper-level winds, sea surface temperatures, and deeper water heat content are all consistent with what has been observed during previous developing El Niños. We are currently experiencing neutral conditions, with ocean temperatures in the Equatorial Eastern Pacific just 0.2°C below the threshold for El Niño. In the week since the El Niño watch was issued, ocean temperatures have remained nearly steady in the Eastern Pacific, so we are not rushing into an El Niño just yet. As discussed in detail in an earlier blog post, most of our more advanced El Niño computer models are predicting a weak El Niño event for the coming Atlantic hurricane season. If this indeed occurs, it is likely that Atlantic hurricane activity will be suppressed due to the strong upper-level winds an El Niño usually brings to the tropical Atlantic, creating high wind shear that tears hurricanes apart.
Sea ice extent in the Arctic near average during May
May 2009 Northern Hemisphere sea ice extent was near average in May, coming in at 15th lowest (16th highest) since 1979, according to the National Snow and Ice Data Center. The record May low was set in 2004. The rate of ice decline in May accelerated, and by the end of the month the decline rate was equal to last year's rate. Warmer than usual temperatures over the Arctic during May contributed to this acceleration. The Arctic remains vulnerable to near-record melting this summer if much warmer than average temperatures occur over the region, since the ice is at record thinness this summer. Thin ice requires less energy to melt, and it also tends to be more fractured, with increased open water amid the ice. Since water absorbs more sunlight than ice, heat from the sun can more rapidly melt this fractured ice.

Just another botched N. Korean missle test or something else :)
He sucked you in,he was looking to stir the pot with that comment.
LoL I am surprised Skyepony did not reply.
Guess we're in the time of year where you get the boomers in the late afternoon and throughout the evening.
That seems way to little. I think they are overplaying the El Nino.
Futurement~ No need, you said it best with A one day record does not necessarily negate global warming

AGW cannot be confirmed or denied with any level of confidence. We have a hard time predicting the weather 3 days out let alone the complex interaction of the many items from the Solar impacts, through geological impacts and everything in the middle. No computer or model exists that can crunch all of the numbers required to successfully interpret the forces at play. I think a better term for it would be Anthropopulative Global Warming. We treat symptoms and not the illness. Just my take on the way out :)
The study finds that Americans are already being affected by climate change through extreme weather, drought and wildfire trends and details how the nation’s transportation, agriculture, health, water and energy sectors will be affected in the future. The study also finds that the current trend in the emission of greenhouse gas pollution is significantly above the worst-case scenario that this and other reports have considered.
Among the main findings are:
Heat waves will become more frequent and intense, increasing threats to human health and quality of life. Extreme heat will also affect transportation and energy systems, and crop and livestock production.
Increased heavy downpours will lead to more flooding, waterborne diseases, negative effects on agriculture, and disruptions to energy, water, and transportation systems.
Reduced summer runoff and increasing water demands will create greater competition for water supplies in some regions, especially in the West.
Rising water temperatures and ocean acidification threaten coral reefs and the rich ecosystems they support. These and other climate-related impacts on coastal and marine ecosystems will have major implications for tourism and fisheries.
Insect infestations and wildfires are already increasing and are projected to increase further in a warming climate.
Local sea-level rise of over three feet on top of storm surges will increasingly threaten homes and other coastal infrastructure. Coastal flooding will become more frequent and severe, and coastal land will increasingly be lost to the rising seas.
By breaking out results in terms of region and economic sector the report provides a valuable tool not just for policymakers but for all Americans who will be affected by these trends. Its information can help:
Farmers making crop and livestock decisions, as growing seasons lengthen, insect management becomes more difficult and droughts become more severe;
Local officials thinking about zoning decisions, especially along coastal areas;
Public health officials developing ways to lessen the impacts of heat waves throughout the country;
Water resource officials considering development plans; and,
Business owners as they consider business and investment decisions.
It is kind of like arguing if their is a God or not, some have faith in one belief others have faith in the other side, either way, your still responsible for yourself and what you contribute to this earth
of course, the 11 'record' high temperatures recorded during the past 16 or so days will STAY part of the temperature record, regardless of the faulty sensor.
My prediction:
Named storms: 10-14
Huricanes: 3-6
M. Hurricanes: 1-4
yea,I'm here how was your trip???,I actually have the same unit installed on a pole on my about 40ft high(total)on top of my 3rd story balcony right here on the beach,it works great,however I have to get a new usb hook up for my internet and then it'll be rapid firing to WU and I'll have it on my blog page as well,so you could say I'm familiar w/the units operation!!!,I'm still on stand-by and have been looking for TC gear at local yard sales;)
Imagine the arguments in here if that verifies...."dead season"..."boring".... vs. "it only takes one".
In the last year, this report went through three periods of public comment. In response to loads of comments (including the large detailed set that I contributed), tweaks were made and glaring errors corrected. But by and large, the same general sentiment remained in place throughout—that is, anthropogenic climate change has made, is making, and will continue to make, things worse for Americans. Evidently, all aspects of the CCSP report were forced to support that general concept—whether or not they do so in reality when all scientific evidence is fairly considered.
Forget that, I'm buying popcorn to watch the show with.
ATTA BOY!!

I have never seen so much preseason canal prep in this area. I had e-mailed the head of canals for the area with the gfs of 26 inch for the area a few days before Fay hit. He was in disbelief but deployed his people to prepare anyway. I think he's taken serious our discussion after about how much more moist the blobs has been the last few years.

Do you have faith in gravity? It's a scientific theory.
The theory of AGW is based on data that is studied by scientists who do not put faith into their findings, just hard work. Faith does not get you published in peer reviewed scientific journals.
Calling AGW a religious belief is no different than labeling any other scientific theory as such: Gravity, Relativity, Evolution, etc.
