Climate Phenomenon In Pacific Weakens

But La Nina Will Continue To Affect Global Climate Through Mid-Summer, NOAA Says

(AP)  The La Nina climate phenomenon under way in the Pacific Ocean has weakened but is expected to continue at least through midsummer, government weather forecasters said Thursday.

La Nina is a periodic cooling of the tropical Pacific sea surface that reduces rainfall in the region and can affect weather around the world.

Its primary effect over the United States in spring and summer is below-average rainfall over parts of the Southwest, extending from Texas to Nevada.

It tends to produce above-average rains over Indonesia.

The National Oceanic and Atmospheric Administration said sea surface temperatures across the central and east-central equatorial Pacific were about 1.8 degrees Fahrenheit below average.

In December, the cool areas ranged from 1.8 degrees Fahrenheit to 7.2 degrees Fahrenheit below normal.

Despite this improvement, forecasters said they expect La Nina to continue through July.

La Nina is the opposite of the better known El Nino condition in which the equatorial Pacific becomes warmer than normal.

"...While these measurements give much less precise estimates of carbon dioxide concentration than ice cores, there is evidence for very high CO2 concentrations ( 3,000 5L/L) between 600 and 400 Myr BP and between 200 and 150 Myr BP.On long timescales, atmospheric CO2 content is determined by the balance among geochemical processes including organic carbon burial in sediments, silicate rock weathering, and vulcanism. The net effect of slight imbalances in the carbon cycle over tens to hundreds of millions of years has been to reduce atmospheric CO2. The rates of these processes are extremely slow; hence they are of limited relevance to the atmospheric CO2 response to emissions over the next hundred years. In more recent times, atmospheric CO2 concentration continued to fall after about 60 Myr BP, and there is geochemical evidence that concentrations were 300 5L/L by about 20 Myr BP. Low CO2 concentrations may have been the stimulus that favored the evolution of C4 plants, which increased greatly in abundance between 7 and 5 Myr BP.

Although contemporary CO2 concentrations were exceeded during earlier geological epochs, present carbon dioxide levels are likely higher now than at any time during the past 20 million years and at the same time lower than at any time in history if we look at time scales longer than 50 million years."

But, if ''global warming'' is real, how can such huge areas of ocean, which the ''global warming'' adherents claim is warming faster than land because they are huge heat-sinks, be ''colder'' than average?

What really stinks, is now that people are starting to see that global warming is not occurring as predicted, many of those who has supported it will state " The decline in temperatures is due to the reduction in green house gases.". I really despise people who jump on a band wagon withough taking time to do their own research.

"Gosh, you got 10 days worth of data, so OF COURSE you can extrapolate that out to 30 years. That''''s about your speed!

Take a look at temp trends over the last 20 years. Tells a pretty sobering story that your wild-enthusiasm for 3 years of data can''''t refute... Exxon.

And weather forecasters, with decades of previous data, have a hard time predicting what the weather will be in a week, let alone 10 to 20 years.

However, when climatologists factor in the solar cycle, they get very accurate long-range generalizations. Look up the Maunder Cycle, which lasts for several decades and can affect global weather for a century or more. The predictions are that one is starting. Global temps have not risen since 1998, which fits in with a Maunder Cycle.

The last time we had a Maunder Cycle was during the Little Ice Age a few centuries ago.

Check out last year''s story:

http://www.cbsnews.com/stories/2007/02/28/tech/main2523483.shtml?source=search_story

Less hurricanes than forecast, and La Nina was stronger.

And what, didn''t this years predication come out last week? They said above average hurricane season is predicted.

According to their own data sets, shouldn''t that have been ''below'' last years predictions in stead of ''above''?

When was the last time they looked at the data, and made a decision based on it, and not on so-called ''global warming''?

ubrew, you Algore worshippers aren''t any better, looking at 20 years of data, or 30, or whatever set you think proves your hysteria.

Try looking at the last, oh, 10,000 years, and you''ll see it''s the same ol'' same ol'' on planet earth... except now we have climate snake oil salesmen like Algore trying to make a profit and control others with it.

Well the latest incidence of global warming ended in 1998, and it hasn''t done much ever since except it got within a quarter degree of 1998, in jan 2007 and then from jan 2007 to jan 2008 it plummeted all the way down to where we were in 1000 AD (according to Michael Mann''s hockey stick graph). The 2007 drop refroze the arctic ocean at a rate of 58,000 square miles per day, for ten days straight; so right now Greenland is sitting with record ice thickness, and no signs of any warming.
The cognoscenti say from now on it will cool down for about the next 20-30 years.

Sorry Al, you bet on the wrong nag !

By the way, it was just announced today that US temp averages in March 08 were .4 degrees F below the century average.
