Sergeant Reed - who eventually arrested a suspect after staking out a Kern County vineyard - is just one of dozens of deputies on the front lines of agricultural crime in California, home to the nation's most productive farms and the people who prey on them. While thievery has long been a fact of life in the country, such crimes are on the rise and fighting them has become harder in many parts of California as many grants for rural law enforcement have withered on the vine.

While other states have their own agricultural intrigue - cattle rustlers in Texas, tomato takers in Florida - few areas can claim a wider variety of farm felons than California, where ambushes on everything from almonds to beehives have been reported in recent years. Then there is the hardware: diesel fuel, tools and truck batteries regularly disappear in the Central Valley, the state's agricultural powerhouse, where high unemployment, foreclosures and methamphetamine abuse have made criminals more desperate, officials say.

"All of our ag crimes are up," said Sergeant Reed, who oversees a unit of two full-time detectives - down from three a year ago - all patrolling a county about eight times the size of Rhode Island. A wet winter and warm summer, after all, have meant healthy crops, he said, and a healthy market means happy thieves.

"Everything this year is doing well," Sergeant Reed said. "And if it's doing well here, there's somebody looking to steal it."

Portions of a National Ground Intelligence Center study on the lethal effects of electromagnetic pulse (EMP) and high-powered microwave (HPM) weapons revealed that the arms are part of China's so-called "assassin's mace" arsenal - weapons that allow a technologically inferior China to defeat US military forces.

EMP weapons mimic the gamma-ray pulse caused by a nuclear blast that knocks out all electronics, including computers and automobiles, over wide areas. The phenomenon was discovered in 1962 after an above ground nuclear test in the Pacific disabled electronics in Hawaii.

The declassified intelligence report, obtained by the private National Security Archive, provides details on China's EMP weapons and plans for their use. Annual Pentagon reports on China's military in the past made only passing references to the arms.

"For use against Taiwan, China could detonate at a much lower altitude (30 to 40 kilometers)... to confine the EMP effects to Taiwan and its immediate vicinity and minimize damage to electronics on the mainland," the report said.

In the end, there were important resolutions to announce after all. Euro-zone heads of state and government agreed on Thursday evening to a second emergency aid package for Greece "and some other things," said German Chancellor Angela Merkel following the special summit of the 17 euro-zone member states in Brussels. She exuded satisfaction and said it had been an "important day."

In the weeks prior to the summit, Merkel had repeatedly insisted that there was no need for the special summit and she made it clear that she was not enthusiastic about participating. As recently as Tuesday, she warned that one should not expect any "spectacular" moves. And the Thursday agreement does indeed fall short of being spectacular, but it provides the clarity that was so badly needed.

The new package provides for 109 billion euros worth of credit for Athens. The majority of the fund comes from the euro backstop fund known as the European Financial Stability Facility (EFSF) and from the International Monetary Fund (IMF). Private creditors are to contribute an additional 50 billion euros by 2014 via a combination of debt buybacks and swaps. The level of private involvement in the plan is much higher than had been expected and reflects the position that Germany had been insisting on for months. It can be seen as a personal success for Merkel.

At the same time, the EFSF is to be granted additional, pre-emptive competencies to prevent the euro crisis from spreading to additional countries. Among other measures, the EFSF will have the ability to buy state bonds on secondary markets - from banks and insurance companies for example - in order to support debt-ridden euro-zone countries. It is a further step in the direction of the kind of transfer union that Germany has long insisted must be avoided.

The plan will likely lead rating agencies to downgrade Greece to default status for several days this autumn. But government leaders consider the risk to be manageable. Once the new bonds, guaranteed by the EFSF, are issued, Greece will be upgraded again - according to the plan, at least. How exactly the markets will react, however, remains to be seen.

As much as 50% of the US population was under a heat advisory, officials said. Meteorologists have put the temperatures down to a "dome" of high pressure in the atmosphere. On Thursday, many regions in the central US and parts of the eastern seaboard also saw heat indexes - a combination of temperature and humidity - topping 43C.

"This is an exceptionally strong ridge of high pressure that really has an exceptional scope and duration," Eli Jacks, a meteorologist with the National Weather Service, told the BBC. "The air is sinking, as it sinks it compresses and gets warmer." It also dries out, so few clouds form to block the high early-summer sun, he said.

The combination of high heat and high humidity made it hard for the human body to cool itself - because sweat does not evaporate efficiently, he added. Across the central and eastern US, people and animals alike have been struggling to keep cool amid the oppressive heat and humidity. As the heat peaks in major population centres on the east coast, the number of deaths is expected to rise, officials warn.

By Friday, the low pressure system moving east is expected to bring thunderstorms with hail to the north-eastern US. Meanwhile, as half of the country's 310 million residents sizzle, states in the north-western region of the country were experiencing abnormally cool temperatures. "I didn't know it could be this cold in July. It is absolutely freezing here in Seattle," said one user of the micro-blogging website Twitter.

The most severe heat-wave in modern North American history took place during the Great Depression in 1936. The heat that summer was blamed for more than 5,000 deaths in the US and Canada.

A spokesman for al-Shabab, which has ties to al-Qaeda and controls much of the country, accused aid groups of being political. Most Western aid agencies quit Somalia in 2009 following al-Shabab threats. The United Nations World Food Programme was one of those banned. It says it is planning to airlift food into the capital, Mogadishu, in the coming days to help the thousands of malnourished children who face starvation in the country.

Some 10 million people are said to need food aid across East Africa but Somalia is by far the worst affected country, as there is no national government to co-ordinate aid after two decades of fighting. The two districts where a famine has been declared - Bakool and Lower Shabelle - are under al-Shabab control and aid agencies have been wary of resuming activities there amid fears for the safety of their staff.

Al-Shabab spokesman Ali Mohamud Rage told journalists in Mogadishu on Thursday night: "The agencies we banned are still banned. The agencies were involved in political activities." He admitted there was a drought but said reports of a famine were "utter nonsense, 100% baseless and sheer propaganda. There is drought in Somalia and shortage of rain but it is not as bad as they put it."

On Wednesday, UN Secretary General Ban Ki-moon said $300 million (184 million pounds) was needed in the next two months to provide an adequate response to the areas affected by famine. "Children and adults are dying at an appalling rate," he said. Nearly half the Somali population - 3.7 million people - were in crisis, he said, with most of them in the south. These are mostly areas under al-Shabab control.

Billy Whitten can't remember ever having to deal so much water and so little water at the same time, much less having the two extremes right next to each other. "This is very unusual this year to have the drought and the flood at the same time," Whitten says. "Normally, when we have a flood, we have some rain to go along with it. This year we've had the flood and no rain at all, so we're just getting it from both ends. We're either flooded or drought destroyed it."

Flooding impacted more than a half-million acres of farmland in Mississippi. At the same time, 25-million acres, or 84% of the state's land, is under some form of drought. Two hundred acres of Whitten's corn was covered by two to three feet of water for nearly two months, destroying $200,000 worth of crops. Just next to those flooded fields are his 1,150 drought-stricken acres of corn. Whitten says he'll be lucky to harvest half of what he normally does, and can only hope next season will be better.

The total impact of flooding and drought on this year's crop won't be known until after harvest, which usually begins in late August. John Michael Riley, an agricultural economist with the Mississippi State University Extension Service, expects damages to be well into the hundreds of millions of dollars. "The estimates for the state range anywhere from $100 million to $500 million worth of damage from the crops that were lost or damaged as a result of the flooding... The drought estimates on row crop in the delta Mississippi could be in that same ballpark of $100 million to $500 million dollars worth of damages," Riley explains.

Eurozone leaders have still failed to address the underlying problem of Greek solvency. Without some form of long term debt relief and a sustainable plan to return the Greek economy to growth, taxpayers will continue to be heavily exposed to a Greek default. A second bailout and the expansion of the EFSF may provide a liquidity boost, but will ultimately transfer risk away from the private sector onto the books of taxpayer-backed institutions.

It looks as if Greece will be forced into some kind of temporary default, but the mechanisms for dealing with this look to be thin on the ground. This plan offers the negatives of a default, albeit a temporary one, without proper backstops or the positives of long term debt relief, which is what Greece, and potentially other struggling eurozone countries, really need.

The deficit reduction debate is coming up against an August 2 deadline when the $14.3 trillion (8.77 trillion pounds) limit on America's borrowing capacity is exhausted, putting in jeopardy payments on US Treasury debt as well as paycheques for federal employees and soldiers. If an agreement is reached to raise the debt ceiling but nothing meaningful is done in terms of deficit reduction, the US would likely have its rating cut to the AA category, S&P said.

"While banks and broker-dealers wouldn't likely suffer any immediate ratings downgrades, we would downgrade the debt of Fannie Mae, Freddie Mac, the 'AAA' rated Federal Home Loan Banks, and the 'AAA' rated Federal Farm Credit System Banks to correspond with the US sovereign rating," S&P said in its report. "We would also lower the ratings on 'AAA' rated US insurance groups, as per our criteria that correlates insurers' and sovereigns' ratings," the firm said.

However, S&P said it sees a failure to reach an agreement on raising the debt ceiling and reducing deficits as the least likely scenario, adding that in such a case the global financial markets would be in turmoil and "likely shove the US economy back into recession." In such a hypothetical case, it envisages the US Treasury curtailing spending sharply and the US Federal Reserve launching another round of quantitative easing to help prop up the economy.

The leaders met in Brussels after the European Central Bank signaled in a policy reversal that it was willing to let Greece default temporarily as part of a plan involving longer official loans at cheaper rates, a debt swap, a bond buyback but no new tax on banks. Minds have been concentrated by the danger that Europe's debt crisis could engulf the much bigger economies of Spain and Italy. Greece, Portugal and Ireland have already succumbed.

The draft summit statement obtained by Reuters showed the EFSF rescue fund would be allowed for the first time to help states earlier with precautionary loans, to recapitalize banks and to intervene in the secondary bond market. "To improve the effectiveness of the EFSF and address contagion, we agree to increase the flexibility of the EFSF," it said, listing those three key steps, all of which Germany had previously blocked.

German Chancellor Angela Merkel and French President Nicolas Sarkozy crafted a common position in late night talks in Berlin with ECB President Jean-Claude Trichet. "I expect we will be able to seal a new Greece program. This is an important signal. And with this program we want to grasp the problems by their root," Merkel told reporters on arrival in Brussels. Dutch Finance Minister Jan Kees de Jager said a short-term or selective default for Greece, long vehemently opposed by the ECB, was now a possibility.

"The demand to prevent a selective default has been removed," he told the Dutch parliament.

The idea was that if several of our biggest banks collapsed at the same time the financial system would not be strong enough to keep things going and economic activity all across America would simply come to a standstill. Congress was told that if the "too big to fail" banks did not receive bailouts that there would be chaos in the streets and this country would plunge into another Great Depression. Since that time, however, essentially no efforts have been made to decentralize the US banking system.

Instead, the "too big to fail" banks just keep getting larger and larger and larger. Back in 2002, the top 10 banks controlled 55 percent of all US banking assets. Today, the top 10 banks control 77 percent of all US banking assets. Unfortunately, these giant banks are also colossal mountains of risk, debt and leverage. They are incredibly unstable and they could start coming apart again at any time. None of the major problems that caused the crash of 2008 have been fixed. In fact, the US banking system is more centralized and more vulnerable today than it ever has been before.

It really is difficult for ordinary Americans to get a handle on just how large these financial institutions are. For example, the "big six" US banks (Goldman Sachs, Morgan Stanley, JPMorgan Chase, Citigroup, Bank of America, and Wells Fargo) now possess assets equivalent to approximately 60 percent of America's gross national product. These huge banks are giant financial vacuum cleaners. Over the past couple of decades we have witnessed a financial consolidation in this country that is absolutely unprecedented.

This trend accelerated during the recent financial crisis. While the big boys were receiving massive bailouts, the hundreds of small banks that were failing were either allowed to collapse or they were told that they should find a big bank that was willing to buy them.

But someday the dominoes are going to start to fall and the house of cards is going to come crashing down. It is an open secret that our financial system is fundamentally unsound. Even a lot of people working on Wall Street will admit that. It is just that people are so busy making such big piles of money that nobody wants the party to stop. It is only a matter of time until some of these big banks get into a huge amount of trouble again. When that happens, we might really find out whether they are "too big to fail" or whether we could get along just fine without them.

So could we potentially see a repeat of 2008? Sadly, when the next big financial crisis happens it might be worse than 2008. Back in the middle of 2008, the US national debt was less than 10 trillion dollars. Today it is over 14 trillion dollars. Back in 2008, none of the countries in the EU were on the verge of financial collapse. Today, several of them are. This time if the global financial system starts falling apart the big governments around the world are not going to be able to do nearly as much to support it. That is why what is happening right now is so alarming. As signs of weakness spread, the short sellers and the speculators are starting to circle. They can smell the money.

Back in 2008, bank stocks led the decline. Today, that appears to be happening again. The "too big to fail" banks are getting absolutely pummeled right now. Most people don't have much sympathy for the banksters, but if we do see a repeat of 2008 they are going to be cutting off credit and begging for massive bailouts once again, and that would not be good news for the economy.

In Europe, the EU sovereign debt crisis just seems to get worse by the day. Bond yields for the PIIGS are going haywire. The higher the yields go, the worse the crisis is going to get. Meanwhile, as I have written about previously, a bad mood has descended on world financial markets. Pessimism is everywhere and fear is spreading. The short sellers and the speculators are eager to jump on any sign of weakness. Investors all over the globe are extremely nervous right now.

So what happens next? Well, nobody knows for sure. But things certainly do not look good. The financial news is just going to keep getting worse. This financial system is simply unsustainable. It is fundamentally unsound. The reality is that financial bubbles cannot keep expanding forever. Eventually they must burst.

Over the next few weeks, keep a close eye on banking stocks and keep a close eye on European bond yields. Hopefully things will stabilize.

Hopefully the next wave of the financial collapse is not about to hit us.

Hopefully the entire global financial system is not on the verge of a major implosion.

But you might want to get prepared just in case.

Charles Plosser, president of the Philadelphia Federal Reserve Bank, said the US central bank has for the past few months been working closely with Treasury, ironing out what to do if the world's biggest economy runs out of cash on August 2. "We are in contingency planning mode," Plosser told Reuters in an interview at the regional central bank's headquarters in Philadelphia. "We are all engaged... It's a very active process."

Plosser said his "gut feeling" was that President Barack Obama and Congress will come to an agreement to increase the Treasury's borrowing authority in time to avert a default on government obligations. Obama was due to meet with top Republicans in Congress on Wednesday to discuss the latest attempts to end the dispute over raising the country's debt ceiling, a row which has raised the prospect of the Treasury Department running out of money to pay its bills next month.

The Treasury has repeatedly said default was unthinkable and that there was no alternative to raising the debt ceiling. Plosser's remarks marked the most extensive public comments yet on preparations for a default from a US official. A Treasury spokesperson could not be immediately reached for comment.

Fed Chairman Ben Bernanke last week warned that a default could have "catastrophic" effects on financial markets. Plosser, a former dean of the Simon School of Business at Rochester University, was more circumspect. "It could be very bad. At some level we don't really know what the consequences could be. It could be very serious. It could be less serious. Do we really want to run that experiment?"

Early on Thursday morning, after seven hours of talks, Germany and France reached a common position on a second bailout of Greece but details of the the accord were not revealed. The German chancellor and the French president had been barraged with pleas from political and financial leaders to reach an agreement - or risk the collapse of the single currency.

The accord between the two most powerful states in the eurozone will now be presented to the crisis summit in Brussels on Thursday of all 17 leaders of the bloc, described as the "last chance saloon" for the euro project. Mr Sarkozy decided to travel to Berlin after the pair repeatedly failed to agree on how to get private bondholders to share the costs of a new 115 billion euros (101 billion pounds) bail-out for Greece.

Jose Manuel Barroso, the president of the European Commission, said: "Nobody should be under any illusion: the situation is very serious. It requires a response. Otherwise the negative consequences will be felt in all the corners of Europe and beyond."

In a rare outburst, Mr Barroso, accused European leaders of endangering "a strong single market and a strong euro. That is what is at stake. That is why we must provide a solution tomorrow. I believe now is the time to decide," he said. "Leaders need to come to the table saying what they can do and what they want to do and what they will do. Not what they can't do and won't do."

"Part of the reason it is called 'tiger' is also because it is very aggressive," says Dina Fonseca, an associate professor of entomology at Rutgers University. "You can try and swat it all you want, but once it's on you, it doesn't let go. Even if it goes away, it will be back for a bite."

Since urban areas tend to be warmer - often by 5 to 10 degrees - than rural areas, cities are seeing tiger mosquitoes earlier and sticking around longer, often into October. "The Asian tiger mosquito arrived this year in June - three months earlier than last year," says Wayne Andrews, superintendent of the Bristol County Mosquito Control Project in Taunton, Massachusetts.

The species has been traced to 1985, when a ship arrived in Texas loaded with used truck tires, perhaps from Japan, which is a major used-tire exporter, according to research by the Centers for Disease Control and Prevention. The eggs hatched when they were exposed to water. Since then, the species has made its way from Texas to Florida and up the East Coast, says Gary G Clark, a research leader with the Agriculture Department. "Now, more than half of the states have this aggressive species," he says.

These urban mosquitoes are what entomologists call "container mosquitoes." Instead of marshes and natural bodies of water, both Asian tiger and rock pool mosquitoes can breed in small, artificial containers, such as tires, toys, cans and concrete structures. "A rule of thumb for container mosquitoes is: Water plus seven days equals mosquitoes," Dr Fonseca says.

Reports suggest a new tax on banks will also be debated. But German Chancellor Angela Merkel has cautioned against over optimism. Greece received its first aid package in May last year, but the debt crisis continues to undermine confidence in global financial markets, with some commentators suggesting it threatens the future of the euro itself.

Politicians and investors are calling for decisive action to help bring the crisis to an end. "Nobody should be under any illusion; the situation is very serious," European Commission President Jose Manuel Barroso said on Wednesday. "It requires a response. Otherwise, the negative consequences will be felt in all corners of Europe and beyond."

President Barack Obama has also weighed in, calling Mrs Merkel on Tuesday night to stress the importance of tackling the debt crisis in sustaining the global economic recovery. The International Monetary Fund has also called on European leaders to take swift and decisive action. Delaying such action further would be "very costly" for the world economy, it said.

Germany has proposed allowing Athens more time to repay, effectively rolling over existing debts into new bonds. It wants private investors, largely banks, to participate in this restructuring. But the European Central Bank has strongly opposed this plan, arguing that such a rollover would constitute a default in the eyes of the international credit ratings agencies and, as such, would undermine investor confidence and the euro itself.

An alternative way to get private investors to contribute to any aid package would be to introduce a new bank tax. Reports suggest leaders will discuss precisely such a tax, even though this would prove hugely unpopular with the banks. It is these divisions that explain Mrs Merkel's attempts to dampen expectations ahead of the summit. The summit will take place in Brussels at 1300 local time (1100 GMT).
