April 2011 was the globe's 7th warmest April on record, according to the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC). NASA's Goddard Institute for Space Studies rated April the 4th warmest on record, tied with April 2005. April 2011 global ocean temperatures were the 11th warmest on record, and land temperatures were the 6th warmest on record. The UK had its hottest April on record, with rainfall only 21% of average. Huge fires burned through Scotland, England, and Northern Ireland, fanned by strong spring winds.

La Niña fades to neutral
The La Niña that began in June 2010 is now transitioning to neutral conditions, according to the Climate Prediction Center. Sea surface temperatures (SSTs) in the equatorial Pacific off the coast of South America are now just 0.4°C below average, the first time since June 2010 that these temperatures have not been 0.5°C or more cooler than average, the threshold for a La Niña. However, it is possible that these water could cool a bit again over the next few weeks, so NOAA has not yet declared an official end to this La Niña episode. Equatorial SSTs were 0.5°C below average in the central Pacific, and average to above-average temperatures have emerged in the eastern Pacific. While this signals the end to La Niña, the CPC cautions that the atmosphere is still behaving like La Niña is continuing. An animation of SSTs since February shows the weakening La Niña nicely. Springtime is the most common time for a La Niña event to end; since 1950, half of all La Niñas ended in March, April, or May.

Arctic sea ice 5th lowest on record
Arctic sea ice declined slowly through most of April, and had the 5th lowest extent since satellite record began in 1979, according to the National Snow and Ice Data Center. However, sea ice extent began declining more quickly toward the end of the month, and as of May 16 was the second lowest on record.

I'll have more on the Mississippi River flood next post. If you haven't seen it, read my post, America's Achilles' heel: the Mississippi River Old River Control Structure.

Just in case there are some on here lurking and wondering what the "End Times" remarks are referring to...

The End

Edit: May 21st is "The Beginning of the End" =)


That is a bunch of bull crap!!! It says in the WORD of GOD that no man will no the day nor hour of the Coming of Christ. These people are idiots and are going to face their judgement for tricking people into thinking that Saturday is the last day on Earth. Many people will commit suicide knowing they gave up everything for this thinking. Idiots!! Read the bible itself and then tell me Judgement day is on Saturday. The word of God says no one knows the day nor hour of His Coming.

Nicaragua's Telica volcano spewed a massive cloud of gas and ash into the air Tuesday following several strong explosions. Material was ejected 1.2 kilometres into the air above the crater of the 1,060-metre volcano, the seismological institute Ineter said. A total of 50 explosions were recorded. Since May 9, Ineter has recorded 59 seismic shocks in the area, and Telica had ejected a large amount of sand on nearby cities since Friday. Sixty nearby villages were evacuated as a precautionary measure. The volcano is located in Leon province, some 130 kilometres north-west of Managua. It last erupted in 1948.


Neo~ I was thinking a little higher than 88 Mon & Tues.. or maybe all the volcano caused cloudiness will off set some hell & brimstone..

Somehow,I'm sure it involves giving money to the messenger!

Right? Funny thing is they still promote listening to their radio channel...if things were ending in a few days, why try to self promote? Mighty dollar right to "The End"

It's a good read though. I like that the dates coincide with the season...could be VERY interesting this year! =)

How is this statistic determined? Diameter of gale force or hurricane winds? It seems you could come up with several different answers. Wasn't Igor of last year one of the largest ever?

Just to clarify, if it does happen in the middle of my backswing, am I entitled to a Mulligan?

I want to make sure my buddies are clear on the Rapture Rules before we start the round.


As long as you abide by the "one mulligan per 9 holes" rule, I think you should be fine. Of course, no one is going to be checking your score sheet afterward, so I'd give yourself a birdie and play through to the next hole.

On the weather front...what happened to the storms we were supposed to get in Palm Beach yesterday. Oh well...can't complain because it's beautiful today.

Does anyone know what time on Saturday the world will end? I need a haircut (want to look good for the Big Guy Upstairs) and I have a 10:45 tee time. I'd hate for the world to end right in the middle of my backswing.
they say around 6 pm or just after the end comes with the first 10.2 quake off new zealand massive global tidal wave of purple kool aid follows the big nap right after the dip in the drink

In the absence of a Confirmed Time, I will probably stay in bed all day.

Boy the Euro is getting interesting it is showing a lowering of pressures in the Western Caribbean next week. You can also see a disturbance or tropical wave heading north up out of the NW Caribbean early next to mid next week. Looks like the Caribbean is about to get active over the next several days.


Yeah. I think that's what this says... Link

THE LARGEST DIFFERENCES IN THE MODELS COME BY THE WEEKEND WHEN THE GFS DEVELOPS A SURFACE LOW ALONG THE TROPICAL WAVE AS IT PASSES THROUGH THE WESTERN CARIBBEAN. THE 00Z GFS SOLUTION IS THE DEEPEST OF THE MODELS AND IS THE ONLY ONE TO CARRY 20 KT
WINDS ON THE NE SIDE OF THE LOW OVER THE WEEKEND AS IT MOVES W-NW THROUGH THE SW CARIBBEAN. THE 00Z NOGAPS AND UKMET BRIEFLY CARRY A CLOSED LOW ALONG THE WAVE...BUT DO NOT BUILD 20 KT
WINDS. MEANWHILE...THE 00Z ECMWF IS EVEN WEAKER STILL AND MAKES THE WAVE INDISTINGUISHABLE BY SUN. CONFIDENCE IS LOW IN THE STRONG GFS...BUT THERE SEEMS TO BE ENOUGH MODEL AGREEMENT TO AT
LEAST CARRY THE WAVE THROUGH THE SW CARIBBEAN. THEREFORE...USED THE NOGAPS/UKMET SOLUTIONS AS A GUIDE.

What a terrible week here in New England. I don't believe I've seen the sun since Saturday at my house in MA as we've been in a moist easterly flow all week. Has rained off and on heavily every day, wish I could send some to those who need it.
