It rained all summer here and is still raining and raining in Upstate New York but the rest of the nation has to worry about droughts. Now we hear a new El Nino is gearing up in the Pacific Ocean. This will flip-flop some of the present weather systems which is why we have had several big hurricanes hitting Baja while Florida sits high and dry.
Scientists warn the West about a very serious long-term drought cycle that is just beginning.

September 20, 2006LONGMONT - Future Western droughts could last an average of 12 years, spanning half of the region and severely reducing Colorado River flows that supply millions of people, according to climate projections from a Boulder scientist.
Eighteen of the world's most powerful computer climate models were used in the study, presented Tuesday by Martin Hoerling, of the National Oceanic and Atmospheric Administration.
Hoerling said he was startled by his own findings. But he cautioned that his results are preliminary and have not been published in a peer-reviewed scientific journal.
"The numbers are pretty striking," he said Tuesday at a drought conference sponsored by the Geological Society of America. "Climate change is moving us in the direction of a perpetual state that is of the Dust Bowl type."
I remember the 5 year drought when I was a child in Arizona. The churches used to pray for rain and when it did rain, we ran around in happy hysteria. I remember when the drought ended we also got a November snowstorm. My littlest brother who was born during the drought began to cry with fear when he saw the stuff falling from the sky. The fact that we all ran outside, screaming, terrified him even more.
The population of Arizona during that time was less than half a million. Today, it is many millions and they all use much more water per capita than when I was a child.
The real killer for the west and the great fear of global warming for them is the lack of snow. If the winter isn't cold enough for snow, the water table will drop dramatically. As I know very well on my own eastern forested mountain, summer rains do not equal winter snow at all! When snow melts, it permeates the soil which is why we call spring herebouts 'Mud Season.'
And it is the Big Muddy! My tractor can easily sink up to the running board in this mud. This summer featured much more moisture than winter but we don't have so much as an inch of mud. Melting snow takes all the moisture of the entire winter and perculates it deep into the ground. There is no run-off, there are 'springs' which pop out of the spongey earth. Not only is this water penetrating deeper, it is much cleaner than summer rain. This is due to the perculation effect: the water runs green and pure after filtering through the clays and sands.
Summer run-off is very dirty. So the loss of winter snow has a much, much bigger effect on water quality and availability than quick, violent summer downpours. This is why looking at average rainfall is meaningless.
We had so little snow this year, for example, I was really afraid of a drought situation. The heavy summer rain prevented this but it is much better to have this as snow, not rain. The rains have interfered with harvesting hay, when it is too damp, the corn rots in the fields and the vegetables don't ripen in the warm sun, for example, my tomatoes are exploding and can't be stored easily and the cabbages have mold growing deep within the head.
Since we are going into el Nino, time to review the last one that passed through.

Forecasters say the Prairies will be drier than usual until at least March.The warm weather brought by El Nino meant that cattle could graze well into the fall, rather than eat expensive feed, but the lack of snow could spell trouble once the spring arrives.
"If we don't get rain in the early spring there's going to be a lot of trouble again," said cattle auctioneer Mark Danes.
The drought last summer led to a massive sell-off of livestock as farmers couldn't provide feed or water for their animals.
It already looks like the Midwest is cycling between bad droughts and terrible droughts. This is one of the world's greatest bread baskets and humanity can't afford to see it become a basket case. A great deal of our agriculture depends on sucking up the winter waters from the Rockies. Just as all of Africa has diverted disasterous amounts of water causing the lakes to shrink, for that matter, Eurasia has, too, all the world's lakes are shrinking and with a lack of winter water, this will accelerate.
Lo and behold, the Atlantic is like a pendulum with the Pacific.
COLLEGE STATION, TX, United States (UPI) -
El Nino events occur when the sea surface on the South American side of the tropical Pacific warms dramatically, altering the cycle of heat and moisture fluctuations throughout the ocean and atmosphere. Warm air from the Pacific drifts east, where it raises the temperature of tropical Atlantic waters.But sometimes El Nino is followed by cooling in the tropical Atlantic. Chang and his colleagues believe that`s because the equatorial Atlantic is not a passive recipient of the El Nino weather system, as many had thought, but interferes with the far-reaching effects of El Nino.
This is a classic yin/yang thing. A Hegelian pendulum. This is to be expected since the ecosystem tries to balance things out, one way or another. But overall, it is warming up so the pendulum begins to swing wilder and wilder. As I keep saying, the weather systems won't be like living in the Bahamas all the time, instead, it will swing wildling from Heaven to Hell.
I just read somewhere today that the Artic Ocean has opened up so much this summer, ships now can pass through to the other side. And polar bears have been spotted in the ocean, drowning, desperately trying to swim to somewhere solid. The Norwegian navy has seen many corpses or struggling beasts. This is a bad omen for us all.
