Colombia rainy season floods kill 136

Colombia is experiencing its worst rainy season in at least 30 years, with at least 136 deaths over the past few months and 1.3 million people affected by flooding. Heavy rains in the capital of Bogota on Wednesday brought the Bogota River to its highest level in 30 years, and more rain is in the forecast--the latest forecast from the GFS model (Figure 2)--calls for an additional 3 - 6 inches (75 - 150 mm) in the Bogota region over the coming week.

Colombia's rainy season usually peaks in October, then gradually wanes in November and December. The heavy rains are due to the presence of the Intertropical Convergence Zone, the area encircling the earth near the equator where winds originating in the northern and southern hemispheres come together. When these great wind belts come together (or "converge", thus the name "Convergence Zone"), the converging air is forced upwards, since it has nowhere else to go. The rising air fuels strong thunderstorm updrafts, creating a band of very heavy storms capable of causing heavy flooding rains. This year is a La Niña year, which means there is a large region of colder than average water off the Pacific coast of Colombia. Colder than average water off the Pacific coast enhances rainfall over Colombia, and this year's moderate-strength La Niña is largely to blame for Colombia's deadly rainy season.

I'll have a new post on Tuesday.

I'm replying way late, Jon, but it has always been, and still is, all about the money/power.

Once people realize an issue is being exploited for personal gain at others expense, the issue itself becomes tainted.
I, personally, highly discount the urgency of AGW because of the hype being made by those who would profit from it.

It would appear, from here in the Bahamas, that the hurricane season is indeed over.

You know it's Thanksgiving when Monday feels like Friday. Then so does Tuesday. We actually had a spray of humidity today in ECFL but that was about it.

Ha! I've been thinking it's Saturday today! I've been enjoying the cool, humid conditions today in ECFL - even had a bit of misty rain.

Interestingly, I learned recently that the town of Esquel in the foothills of the Andes in Argentina, voted in a referendum that sought to find public approval for a Gold mine just outside the town. There is a large deposit within a large mountain there.
The mine would have effectively removed a large mountain, (visible from the town) and used Cyanide (typical in gold extraction) in large quantities.

In spite of the need for an improved economy in the area, the population voted 70% against the mine.


At least they had a choice..

AN ACTIVE LOW LEVEL TROUGH IS AFFECTING WEATHER
CONDITIONS OVER TRINIDAD AND TOBAGO.
Trinidad and Tobago have been experiencing cloudy
conditions with intermittent heavy showers over
the last few hours. These conditions are as a
result of an active Low Level Easterly Trough



There is a 40 to 60 % chance that Northern and
Eastern Trinidad can experience longer periods of
heavy showers and thunder showers with
accompanying gusty winds in excess of 50Kmh.
There is a smaller 30 – 40% of the isolated
thundershower affecting other the rest of
Trinidad. Rain fall accumulation can be in the
vicinity of 30 - 40 mm. These conditions are
expected to last for at least the next 4-6 hours.
Street and flash flooding are possible in heavy
showers and thundershowers.

I had no idea that floods were happening in Columbia.
Weather in Trinidad has been deteriorating steady all day,frequent rain storms in Eastern and southern areas.If the gfs is correct well be seeing more than 6 inches in a week.

U.S. corn ethanol "was not a good policy"-Gore Mon Nov 22, 2010 12:24pm GMT

* U.S. ethanol consumes about 40 pct corn crop
* Impact on food prices "real"

By Gerard Wynn

ATHENS, Nov 22 (Reuters) - Former U.S. vice-president Al Gore said support for corn-based ethanol in the United States was "not a good policy", weeks before tax credits are up for renewal.

U.S. blending tax breaks for ethanol make it profitable for refiners to use the fuel even when it is more expensive than gasoline. The credits are up for renewal on Dec. 31.

Total U.S. ethanol subsidies reached $7.7 billion last year according to the International Energy Industry, which said biofuels worldwide received more subsidies than any other form of renewable energy.

"It is not a good policy to have these massive subsidies for (U.S.) first generation ethanol," said Gore, speaking at a green energy business conference in Athens sponsored by Marfin Popular Bank.

"First generation ethanol I think was a mistake. The energy conversion ratios are at best very small.

"It's hard once such a programme is put in place to deal with the lobbies that keep it going."

He explained his own support for the original programme on his presidential ambitions.

"One of the reasons I made that mistake is that I paid particular attention to the farmers in my home state of Tennessee, and I had a certain fondness for the farmers in the state of Iowa because I was about to run for president."

U.S. ethanol is made by extracting sugar from corn, an energy-intensive process. The U.S. ethanol industry will consume about 41 percent of the U.S. corn crop this year, or 15 percent of the global corn crop, according to Goldman Sachs analysts.

A food-versus-fuel debate erupted in 2008, in the wake of record food prices, where the biofuel industry was criticised for helping stoke food prices.

Gore said a range of factors had contributed to that food price crisis, including drought in Australia, but said there was no doubt biofuels have an effect.

"The size, the percentage of corn particularly, which is now being (used for) first generation ethanol definitely has an impact on food prices.

"The competition with food prices is real."
Gore supported so-called second generation technologies which do not compete with food, for example cellulosic technologies which use chemicals or enzymes to extract sugar from fibre for example in wood, waste or grass.

"I do think second and third generation that don't compete with food prices will play an increasing role, certainly with aviation fuels."

Gore added did that he did not expect a U.S. clean energy or climate bill for "at least two years" following the mid-term elections which saw Republicans increase their support.

I actually noticed this article on Fox News, but knew that if I referenced them, most on this website would immediately roll their eyes, and discount the whole of the article. So, I went out and found it on a Reuter’s site found here: Link

http://af.reuters.com/article/energyOilNews/idAFLDE6AL0YT20101122?pageNumber=2&virtualBrandChannel= 0&sp=true

---------------------------------------------
All this time, I, with many others, thought that Mr. Gore was a mission to save the planet. After all, to quote him directly, “the planet has a fever.” I must say, with these revelations, that I am shocked, saddened, and even disillusioned.

After all, if one truly believes in such a serious cause, he would endeavor to use all the tools at his disposal to raise the alarm. To make changes that will have true impacts.

But according to his own words above, he used the cause to further his own political aspirations. It would appear, after all, that Mr. Gore’s motivations may be no better than any other politicians, to further their own causes first, and whatever the fallout, so be it.

Very Respectfully,

Jon

State of emergency in flooded Colombia
By The CNN Wire Staff
November 20, 2010 -- Updated 0332 GMT (1132 HKT)



(CNN) -- Colombian President Juan Manuel Santos has declared a state of emergency in 28 of the nation's 32 departments because of heavy rains and flooding that have affected some 1.2 million people.

He called on the international community to help and said the capacity of the Colombian government is overwhelmed.

Flooding and mudslides have killed at least 136 people, injured 205 and left 20 missing, the nation's Interior and Justice Ministry reported.

Emergency officials say the heavy rain has led to problems in 561 municipalities in the South American nation.

"Many have lost everything they had and the capacity of the government [to help them] has been overwhelmed. We're trying to find ways to get more resources and that's why we're calling on the business sector, the public in general, and the international community to help us because, unfortunately, the situation is getting worse," said Santos.

true - I thought we would get better than we did but its the same old grab when it comes down to civil liberties.

Having fringe groups claiming to support the Constitution pushing ridiculous agendas doesn't help either.

Good afternoon.
Interesting notes on the weather in Columbia re. heavy rainfall.
Flew from Panama City to Trinidad yesterday, and marvelled at the fantastic clouds we saw, all around.
I wondered why the aircraft was weaving around so much, giving a great views of incredible Anvil Clouds looming above us. We were at 30,000 ft.

Had a good view of what I think were the mountains of Merida near the Columbian border of Venezuela. Snow capped and Magnificent.
