Abrupt climate changes and a super volcano

An extremely brief reversal of the geomagnetic field, climate variability and a super volcano
sciencecodex/41,000 years ago, a complete and rapid reversal of the geomagnetic field occured. Magnetic studies of the GFZ German Research Centre for Geosciences on sediment cores from the Black Sea show that during this period, during the last ice age, a compass at the Black Sea would have pointed to the south instead of north. Moreover, data obtained by the research team formed around GFZ researchers Dr. Norbert Nowaczyk and Prof. Helge Arz, together with additional data from other studies in the North Atlantic, the South Pacific and Hawaii, prove that this polarity reversal was a global event. Their results are published in the latest issue of the scientific journal "Earth and Planetary Science Letters".
What is remarkable is the speed of the reversal: "The field geometry of reversed polarity, with field lines pointing into the opposite direction when compared to today's configuration, lasted for only about 440 years, and it was associated with a field strength that was only one quarter of today's field," explains Norbert Nowaczyk. "The actual polarity changes lasted only 250 years. In terms of geological time scales, that is very fast." During this period, the field was even weaker, with only 5% of today's field strength. As a consequence, the Earth nearly completely lost its protection shield against hard cosmic rays, leading to a significantly increased radiation exposure.
This is documented by peaks of radioactive beryllium (10Be) in ice cores from this time, recovered from the Greenland ice sheet. 10Be as well as radioactive carbon (14C) is caused by the collision of high-energy protons from space with atoms of the atmosphere.
The Laschamp event
The polarity reversal now found with the magnetisation of Black Sea sediments has already been known for 45 years. It was first discovered after the analysis of the magnetisation of several lava flows near the village Laschamp near Clermont-Ferrand in the Massif Central, which differed significantly from today's direction of the geomagnetic field. Since then, this geomagnetic feature is known as the 'Laschamp event'. However, the data of the Massif Central represent only some point readings of the geomagnetic field during the last ice age, whereas the new data from the Black Sea give a complete image of geomagnetic field variability at a high temporal resolution.
Abrupt climate changes and a super volcano
Besides giving evidence for a geomagnetic field reversal 41,000 years ago, the geoscientists from Potsdam discovered numerous abrupt climate changes during the last ice age in the analysed cores from the Black Sea, as it was already known from the Greenland ice cores. This ultimately allowed a high precision synchronisation of the two data records from the Black Sea and Greenland. The largest volcanic eruption on the Northern hemisphere in the past 100 000 years, namely the eruption of the super volcano 39400 years ago in the area of today's Phlegraean Fields near Naples, Italy, is also documented within the studied sediments from the Black Sea. The ashes of this eruption, during which about 350 cubic kilometers of rock and lava were ejected, were distributed over the entire eastern Mediterranean and up to central Russia. These three extreme scenarios, a short and fast reversal of the Earth's magnetic field, short-term climate variability of the last ice age and the volcanic eruption in Italy, have been investigated for the first time in a single geological archive and placed in precise chronological order.

 

The Largest Natural Disaster In U.S. History

This is terrible. The food is running short on livestock, and farmers are starting to seel off all the livestock taht they can jsut so they dont die in this heat

Please share if you care

TheAmericanDream/Why is the heartland of the United States experiencing such a horrific drought right now? At the moment, approximately 61 percent of the entire nation is experiencing drought conditions, and this is absolutely devastating farmers and ranchers all over the country. Less than two weeks ago I wrote an article asking what would happen if these drought conditions persisted, and now we are finding out. The U.S. Department of Agriculture has created the largest natural disaster area in U.S. history. The USDA has declared 1,016 counties in 26 U.S. states to be disaster areas. The USDA declaration basically covered about half of the nation, and there is now no denying how horrible this drought really is. You can see a map of this disaster area right here. This endless drought is being compared to the nightmarish drought of 1988, and if it persists into August it could become perhaps the worst drought that America has ever seen. The USDA says that approximately 60 percent of all corn in the country is experiencing "moderate to extreme" drought conditions. If this drought does not end soon, the losses are going to be mind blowing. Already, it is estimated that farmers and ranchers have suffered billions of dollars in damage. How much worse can things get?
At the beginning of July many were hoping that we would soon see some rain and that we could still see a decent corn harvest.
Unfortunately, the drought has gotten even worse since that time. The following is from an article in the Chicago Tribune....

The whole of Iowa was classified as abnormally dry as of July 10 and 12.7 percent of the top corn and soybean producing state was in severe drought, up from 0.8 percent the prior week.
Harder-hit Illinois, the No. 2 corn and soy state, was 66.28 percent under severe drought or worse, up from 40 percent the previous week.
Severe to exceptional drought covered 80.15 percent of Indiana, versus 68.84 percent the prior week.
Conditions in Missouri also deteriorated, with 82.54 percent of the state in severe drought or worse, compared with 78.83 percent the week before.

That is not good news.
Posted below is the latest update from the U.S. drought monitor. As you can see, nearly the entire southern half of the country is extremely dry right now....

It is being projected that in some of the major corn growing areas as much as 60 percent of the crops could be lost.
Many farmers that had been desperately hoping for rain are now becoming resigned to the fact that their crops are not going to make it. The following is from an article in the New York Times....

"Corn is anywhere from knee-high to waist-high," Gonzalee Martin, agriculture and natural resources educator with Purdue University’s Allen County extension office, told The News-Sentinel. "Much of it has already tassled with no ears at all. Much of it’s going to be completely lost"

When your livelihood depends on the weather, an endless drought can be extremely stressful. Many farmers that had been anticipating a bumper crop this year are now faced with an utter disaster. The following example comes from CNN....

Now, as punishing drought grips the Midwest, Villwock, 61, walks his hard-hit 4,000 acres in southwest Indiana in utter dismay.
Where there should have been tall, dark green, leafy plants, there now stand corn stalks that are waist high or, at best, chest high. They are pale in color and spindly. Fragile. Tired.
Pull back an ear's husk and you find no kernels, he says. With temperatures rising above 95 degrees, the pollen starts to die.
"It's emotionally draining," he said. "The crop got out of the ground very well. We were so optimistic. But maybe a few of us were counting our eggs before they were hatched."

So is there any hope that things are going to turn around?
Unfortunately, things do not look promising right now. It is being projected that the Corn Belt will experience extremely high temperatures and very low rainfall all the way through mid-August. The following report comes from accuweather.com....

AccuWeather.com agricultural meteorologists are concerned that new and frequent waves of near-100-degree temperatures and stingy rainfall will further stress crops over Iowa, Illinois and Nebraska into mid-August.

When temperatures are very high and rainfall is very low, evaporation happens very rapidly. As accuweather.com notes, when the ground becomes very, very dry it can create a vicious cycle that feeds on itself....

Evaporation rates are very high into the first part of August. Soaking rain on a regular basis instead of a brief downpour is needed to be of benefit beyond a couple of days.
Turning things around in the Midwest as a whole will be a difficult task as dry ground tends to bring higher daytime temperatures, which in turn raises evaporation rates and so on.

So what does all of this mean for the rest of us?
It is going to mean higher food prices.
On Friday, the price of corn hit $7.50 a bushel.
It had been thought that the price of corn would only be about $5.00 a bushel this year.
At this point, the price of corn is up 48 percent since mid-June, and it could go a whole lot higher.
Some analysts are projecting that if this endless drought persists, we could see ten dollars for a bushel of corn and 20 dollars for a bushel of soybeans.
And yes, you will notice this at the supermarket.
In a previous article, I included a quote from a recent article by Holly Deyo about why the price of corn affects the price of so many other products....

Since 75% of grocery store products use corn as a key ingredient, expect food prices to skyrocket. Corn is also a staple in many fast foods. Corn is in ethanol and the main food source or chickens. In addition to this, maize is in many things that aren't obvious like adhesives, aluminum, aspirin, clothing starch, cosmetics, cough syrup, dry cell batteries, envelopes, fiberglass insulation, gelatin capsules, ink, insecticides, paint, penicillin, powders, rugs and carpets, stamps, talcum, toothpaste, wallpaper, and vitamins. That's just for starters...
This is a huge heads up for you to purchase corn-using products NOW before these conditions reflect in grocery goods. It will be a narrow window of opportunity.

This endless drought is also a complete and total nightmare for ranchers.
At this point, approximately 50 percent of America's pastures and ranges are in "poor" or "very poor" condition.
Back in June, that figure was only sitting at 28 percent.
So things have gotten a lot worse very quickly.
A lot of ranchers are selling off their cattle because this drought is making it very difficult to continue to feed them. The following is from examiner.com....

Rauhn Panting, with the University of Idaho, who works with ranchers and farmers, says, "We're going to run out of grass. It's going to be scary." Ranchers are being advised to vacate grazing lands, weeks and even months before when they usually have to leave.
Left with only two choices, feed or sell, many are opting to sell their cattle. The Torrington Stock Market in Wyoming, has recorded that 36,000 cattle were sold in May and June of this year. The usual average for these months is 5,500. Small ranchers, with 30-50 cow/calf pairs, are being hit the hardest.

So expect higher meat prices in the fall and winter as well.
This all comes at a really bad time. We are already on the verge of a global financial catastrophe. Agriculture was supposed to be one of the few bright spots in the U.S. economy.
Sadly, the U.S. is not the only one having problems with crops this year.
For example, in Germany farmers are actually experiencing a full-blown plague of rats.
Yes, seriously.
The following is from a recent Der Spiegel article....

Millions of field mice are overrunning the central German states of Thuringia and Saxony-Anhalt, much to the concern of local farmers. The rodents are devastating food crops, cutting yields by up to 50 percent. Getting birds of prey to hunt the critters didn't help, and now farmers want to be allowed to use a banned rat poison.

So why is all of this happening?
Why is nature going crazy all of a sudden?
