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.

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.

Been there.
Unfortunately, there was too much shopping every time.
I don't do Malls very well.
Would love to see the Florida 'outback' though.

I haven't had a cigar in 9 month. I prefer Cuban's but the Flor De Filipinas are nice too.

Our Cyclone season may have 1 last system before it's done...
a tropical low is located about 400 kilometres northeast of Timor and this is expected to move slowly southwest over the next 24 to 48 hours. This does carry the slight chance of developing into a category 1 tropical cyclone, and this may have some impact over western parts of the Top End and the Kimberley area around Thursday and Friday. Showers have been forecast for Darwin today and tomorrow.

Tropical cyclones in May are unusual but not unprecedented, with an example being tropical cyclone “Herbie” that struck the WA coast near Carnarvon on 21st May 1988.

Not much happening tonight with the weather.. However, just looking at the radar and seeing the moisture stream across the Southern half of the continental U.S. shows that El Nino is indeed back.

Yes you are correct. I am in Midtown/Museum District area. I know Ritaevac is in this area too, but I believe he is further south (I may be mistaking). We certainly need to keep in touch during storms and etc. I believe Jeffs713 is in this area as well.

Speaking of Tea...

Link

Global warming has not adversely impacted India's agriculture production which has been increasing over the last five years, the Rajya Sabha was informed on Friday.

"In the last five years ... wheat, rice, sugarcane and cotton production has not dropped, but increased," agriculture minister Sharad Pawar said during Question Hour. "In fact," he said, "except for Nigeria, no negative impact of global warming has been reported globally so far". Pawar said a number of reports by several organisations about possible impact of climate change on global agriculture revealed that there would be a 14% deficit in wheat production, 11% in rice and 9% in maize by 2020.

"Indian studies conducted under ICAR Network Project on Climate Change, however, indicate that climate change may reduce yield of timely sown irrigated wheat by about 6% in 2020. While late and very late sown wheat is taken into consideration, the projected impact could reduce the yield by 18%, if no adaptation measures are followed," he said.

Pawar said climate resilient practices on farmers' fields in 100 most vulnerable districts were demonstrated as part of a Rs 350-crore national scheme in 2011, but "by and large, we have not seen impact". Attributing post-harvest losses in fruit and vegetables to shortage of cold storages, he said that during the last three years, 1,066 cold storages with a 5.56-million tonne capacity were set up with a Rs 656.33-crore government subsidy.


Now this doesn't seem actually like credible information, but it is news available to those that live in India. Now this next article actually discusses how global warming has damaged the tea crop.

by By WASBIR HUSSAIN / APS WRITER Wednesday, January 5, 2011

GAUHATI, India — Tea growers in northeastern India say climate change has hurt the country's tea crop, leading not just to a drop in production but also subtly altering the flavor of their brew.

Tropical Assam state, with its high humidity and lush greenery, is India's main tea growing region, producing nearly 55 percent of the country's enormous tea crop. Overall, India accounts for 31 percent of global tea production. But a gradual rise in Assam's temperatures, changes in rainfall patterns and a dip in tea production have plantation owners scared.

Assam is the world's largest tea-growing region, lying on either side of the Brahmaputra River, and borders Bangladesh and Burma. The area in northern India is the source of some of the finest black and British-style teas. Assam teas are notable for their heartiness, strength and body, and are often sold as "breakfast" teas...

Now I do believe that there is some global warming going on, and Ido believe it is influencing the amount of severe weather we are seeing. But I also believe that we see more severe weather because we are more tuned into our surroundings and extreme weather events are sensationalized. We have built on so many river/ flood beds with our desire to live on the water, and covered the land with cement, decreasing the amount absorbed during extreme rain events. The population continues to skyrocket which should will most likely lead to more warming, and a greater number of people experiencing these extreme events. Take the population of Assam, The total population of the state increased from 26,638,407 to 31,169,272 in the last ten years with a decadal growth rate of 16.93 per cent that is lower than the overall national growth percentage 17.64 for the same period. After a year-long census the Directorate of Census Operations of the state has released data on Thursday.Link

Lets look at the sanitation of the state of Assam.
In 2001, 64.6 per cent households had proper sanitation facilities within their premises. In 2011, there was only a slight improvement of 64.9 per cent. The number of households not having such facilities has also declined to 35.1 per cent in 2011 from 35.4 per cent in 2001...Another picture of Assam highlighted in the census report is that 80 per cent of the households still use firewood, crop residue, cow dung cakes and coal for cooking, while only 19 per cent use LPG or PNG, electricity and biogas. While 20 per cent have drainage facility, 79.59 per cent still don't enjoy such facilities against 79.6 per cent in 2001.Link



So with an increase of pop. of almost 5 million( Think South Carolina is the roughly the same size of Assam, and has about a total pop of 5 million) How much has, different types of pollution, water quality among other things changed the tea production. Like I said Global warming has a hand at it, but I'm sure there is a much larger picture, that a lot of people ignore. We are slowly ruining our lands through multiple means of destruction.

Yeah, we enjoyed the HEAT today. And tonight is hot too.
Great clear skies this evening with a wonderful sunset. Strange for May to have cloud down in the west.
But we sat on the deck and watched the mountains in Venezuela with big cloud over them. All pink, yellow, crimson, purple.

Real nice evening.

But it looks like more rain is coming later in the week!

These things never really go in a constant direction. It's a stair-stepping process, especially when coming off such a long La Nina period. The negative phase of the PDO isn't helping El Nino take control as it is pressing down on the equator with cold anomalies. It's going to be a slow process, but El Nino should take over by late fall.
Yeah LATE fall hopefully :).So I can be spoiled by nature,both hurricane season and have a chance of a snowy winter.
