A research team from the Massachusetts Institute of Technology and Colorado State University of the US and the University of Sheffield of the UK has analysed effects of global warming and ozone pollution over 2000–2050 on the worldwide production of wheat, rice, maize and soybean. The study was published in journal Nature Climate Change yesterday.

The scientists found reduction of crop yields by 2050 exceeded 10% of 2000 levels, substantially decreasing food security, in all cases examined. Several scenarios were considered because of uncertainty of future levels of ozone pollution.They estimated by 2050, increasing population and changing diet would increase world food needs by 50 percent.As coauthor Colette Heald told The Huffington Post, “The climate projections are quite consistent […] the future of ozone pollution is very different […] leading to either offsetting or reinforcing effects [of climate change] on crops”.By 2050, undernourishment would increase by either 49 percent or by 27 percent, depending on the scenario.

The study focuses on ozone–temperature covariation: ground-level ozone increases with temperatures.Heald said although temperature and ozone are separately known to impact crop yields, “nobody has looked at these together”.Depending on region and crops, the yields may be primarily sensitive to ozone —in the case of wheat— or heat —in the case of maize— alone, providing a local estimation of relative benefits of climate change adaptation versus ozone regulation.

The U.S. Department of Agriculture notes, “Ground-level ozone causes more damage to plants than all other air pollutants combined”, highlighting the importance of air quality for agriculture. Results of NCLAN studies, published in a paper by AS Heagle in 1989, show dicot species, such as soybean, cotton, and peanut, lose more yield from ozone than do monocot species such as sorghum, field corn, and winter wheat.The researchers found that ozone pollution caused 46 percent of previously heat-attributed damage to soybean crops.

The model does not include the effect of rising carbon dioxide concentration, which has complex and potentially offsetting impacts on global food supply.The U.S. Environmental Protection Agency says some crops may have higher yields with increased levels of carbon dioxide.However, global warming also increases probability of extreme crops-damaging weather events such as floods, droughts, and extreme temperatures. Climate change affects distribution of weeds, pests, and diseases.Heald noted the findings show pollution reduction is also important. “An air-quality cleanup would improve crop yields […] Ozone is something that we understand the causes of, and the steps that need to be taken to improve air quality.”

As Heald told The Huffington Post, US surface ozone has dropped partly due to the Clean Air Act. “Despite an increase in vehicle miles driven and energy consumption, surface ozone has declined by 25 percent on average across the U.S. from 1980 to 2012 […] However, the future of ozone air quality in the U.S. and around the world will depend on local emissions, the use of pollution control technology, regulations, and air quality policy.”

The study was supported by the Croucher Foundation, US National Science Foundation, and US National Park Service.

Queen Elizabeth II, the British monarch, has today withdrawn and annulled a knighthood given to Fred Goodwin in 2004, heeding the advice given to her by a forfeiture committee. Goodwin is the former chief executive at the Royal Bank of Scotland Group (RBS) and was awarded his knighthood by the British government of the time for services to banking. The committee concluded “that widespread concerns about Fred Goodwin’s decision meant that the retention of a knighthood for services to banking could not be sustained.”

Goodwin was chief executive of RBS when they purchased ABN AMRO, a Netherlands bank, in 2007. The British government subsequently bailed out RBS for £45 billion, amidst the late-2000s financial crisis.

British prime minister David Cameron stated about the annulment: “The proper process has been followed and I think we’ve ended up with the right decision.” Cameron and Ed Miliband, UK Leader of the Opposition, both believed Goodwin’s knighthood should be removed. Miliband called it “the start of the change we need in our boardrooms.”

Liberal Democrat leader and Deputy PM Nick Clegg considered it to be the “right decision”. “[A]ppropriate” was the word George Osborne, Chancellor of the Exchequer used to describe it. “RBS came to symbolise everything that went wrong in the British economy in the last decade,” Osborne stated. Alex Salmond, First Minister of Scotland stated the title was given “for services to banking which could not therefore be sustained”, calling the decision “correct”.

Goodwin does not have the right to appeal against the decision, nor had the right to provide the forfeiture committee with any representations. The monarch holds sole responsibility for withdrawing all knighthoods; on this occasion Elizabeth II followed the advice of the committee, who decided to recommend the withdrawal to her. The Cabinet Office announced the advice had been given to the queen on the understanding that “Goodwin had brought the honours system in to disrepute”.

Speaking of the “exceptional case”, the committee explained: “In 2008, the government had to provide £20 billion of new equity to recapitalise RBS and ensure its survival and prevent the collapse of confidence in the British banking system. Subsequent increases in government capital have brought the total necessary injection of taxpayers’ money in RBS to £45.5 billion.” The committee understood that “Fred Goodwin was the dominant decision maker at RBS at the time.”

Until this announcement, criminal conviction and professional expulsion were the only causes for which individuals had their knighthoods revoked.

United States president-elect Barack Obama has announced Shaun Donovan as his choice for the Secretary of Housing and Urban Development. Donovan is currently New York City‘s housing commissioner.

The announcement was made in Obama’s weekly address, in which the president-elect discussed his reasons for selecting Donovan, and discussed the importance of what he announced will be his department.

“To stem the rising tide of foreclosures and strengthen our economy, I’ve asked my economic team to develop a bold plan that will dramatically increase the number of families who can stay in their homes,” stated Obama in his address, adding “few will be more essential to this effort than the Department of Housing and Urban Development.”

“From providing shelter to those displaced by Katrina to giving help to those facing the loss of a home to revitalizing our cities and communities, HUD’s role has never been more important,” continued Obama. “Since its founding, HUD has been dedicated to tearing down barriers in access to affordable housing — in an effort to make America more equal and more just. Too often, these efforts have had mixed results.”

Following the above comments, Obama described why he selected Donovan. “That is why we cannot keep doing things the old Washington way. We cannot keep throwing money at the problem, hoping for a different result. We need to approach the old challenge of affordable housing with new energy, new ideas, and a new, efficient style of leadership. We need to understand that the old ways of looking at our cities just won’t do… No one knows this better than the outstanding public servant I am announcing today as our next Secretary of Housing and Urban Development — Shaun Donovan.”

“As Commissioner of Housing Preservation and Development in New York City, Shaun has led the effort to create the largest housing plan in the nation, helping hundreds of thousands of our citizens buy or rent their homes,” continued Obama. “Prior to joining Mayor Bloomberg’s administration, Shaun worked both in business, where he was responsible for affordable housing investments, and at one of our nation’s top universities, where he researched and wrote about housing issues. “

Donovan previously worked as Deputy Assistant Secretary for Multifamily Housing at HUD, and was acting FHA commissioner under the Clinton administration.

In a report on cloud computing issued this week, the environmental group Greenpeace rated ten top Internet companies, including Apple, Google, Twitter and Amazon, on several factors such as each company’s willingness to be transparent by providing information on its energy sources and the energy efficiency of its data centers.

In the report entitled “How Dirty is your Data”, Apple, while receiving good marks for transparency, rated at the bottom for energy efficiency, primarily because its huge, new data center in North Carolina, called iDataCenter, relies largely on coal. Although Apple claimed its California operations used cleaner energy than that produced by most grids, iDataCenter has an estimated energy demand three times Apple’s current use, significantly increasing Apple’s environmental footprint. As Apple increases the online products it delivers from its iTunes platform, it will enlarge its cloud computing operations further.

“Apple’s decision to locate its iDataCenter in North Carolina, which has an electrical grid among the dirtiest in the country (61 percent coal, 31 percent nuclear), indicates a lack of a corporate commitment to clean energy supply for its cloud operations,” Greenpeace said in its report.

About 2 percent of worldwide energy use is consumed by data center computer servers, and this amount is increasing by 12 percent a year, Greenpeace reports, an energy demand that is more than that of Russia.

Greenpeace said many IT companies do not reveal the environmental impact of their energy consumption, and concentrate more on energy efficiency that on using clean energy. Most of their energy is supplied by coal and nuclear energy. Companies are locating their data centers in areas that afford cheap, abundant coal-powered electricity.

Yahoo was praised by Greenpeace for placing its data centers near sources of clean energy and its minor use of coal-based power.

Greenpeace noted that Google says that it is conscious of the need to use renewable sources of electricity to power cloud computing, but it does not acknowledge the size of its carbon footprint. The company claims it has seven data centers worldwide, but it is estimated to have 20 to 30.

The carbon footprint of cloud computing is a recent emphasis of Greenpeace in its attempt to disprove the belief that the biggest polluters are manufacturers.

In a response to the report, Timothy Prickett Morgan criticized Greenpeace for focusing on data centers which are responsible for using about 3 per cent of the US power generation and globally account for 1.5 to 2 percent. He noted that “the data centers of Amazon, Google, Yahoo!, Facebook, Twitter, IBM, Hewlett-Packard, Microsoft, Apple, and Akamai . . . are probably not much different from the business where you work every day when it comes to dependency on coal for electricity generation. And ditto for the home that you return to every night.”

Morgan quotes data from a 2008 report by the International Energy Agency and cited by the World Coal Association, now known as the The World Coal Institute, that showed coal plants produce over 40 percent of the global electricity. The Institute determined that United States receives half of its power from coal plants. Some other countries, such as South Africa, Poland and China, use more coal. “The world is still dependent on non-renewable energy sources – coal and nuclear with a smattering of oil and gas – to generate electricity,” he says, suggesting the IT companies should not be singled out.

Morgan is also critical of Greenpeace’s methodology in gathering the data, as it included only a sample of the data centers of these companies, and some that were not yet completely operational. He noted that because the companies were not always cooperative in disclosing information, Greenpeace estimated a portion of the data. He said that the reader has to “drill down into the report” to see the the complete picture.

Another criticism of Greenpeace is its definition of coal and nuclear power as “dirty energy”. Because it does not discharge greenhouse gases, nuclear power is rated more favorably than coal by some environmental organizations. Greenpeace is adamantly against nuclear power’s radiation risks.

The United Kingdom is listed second in a report on global cyber-crime statistics, behind the United States and ahead of cyber-crime “hotspots” Nigeria and Romania. The 2007 Internet Crime Report was released in April by the Internet Crime Complaint Center (IC3), a joint operation between the Federal Bureau of Investigation and the National White Collar Crime Center.

Americans reported losses of US$240 million from global cyber-crime in 2007, a $40 million increase from 2006. The Internet Crime Complaint Center received 206,884 complaints of online fraud in 2007, a decrease from the previous year’s 207,492 complaints.

FBI special agent John Hambrick, in charge of the IC3 unit, told the Agence France-Presse “We’re seeing more schemes involving bigger ticket items, get-rich-quick and work-at-home schemes that involve higher dollar losses”. As the report only includes figures from crimes reported to law enforcement, it is likely that real crime numbers were higher.

FBI Cyber Division Assistant Director James E. Finch commented on the report: “The Internet presents a wealth of opportunity for would be criminals to prey on unsuspecting victims, and this report shows how extensive these types of crime have become … What this report does not show is how often this type of activity goes unreported. Filing a complaint through IC3 is the best way to alert law enforcement authorities of Internet crime.”

In response to the report’s release, the information technology consultancy Global Secure Systems (GSS) warned that the United Kingdom is becoming a hotbed of internet crime. According to the report, the UK accounts for 15.3 per cent of online crime from US crime reports. “This is significantly ahead of other cyber-crime hotspots such as Nigeria (5.7 per cent) and Romania (1.5 per cent),” said David Hobson, managing director of GSS, in an interview with vnunet.com.

The 2007 Internet Crime Report cites the top ten countries by amount of perpetrators of online crime. In descending order, the top ten list includes the United States, the United Kingdom, Nigeria, Canada, Romania, Italy, Spain, South Africa, Russia, and Ghana. Scammers living within the United States most often lived in California, Florida, Georgia, Illinois, New York, Pennsylvania, and Texas. Men lost more money to online fraud than women in 2007, and also accounted for 75 percent of cyber-crime perpetrators.

FBI spokeswoman Cathy Milhoan told CIO Today that online scammers attempt to take advantage of the good will of individuals, asking for money for purported charities during crises. “The scammer tries to prey on victims who are kind of in tune with what’s going on in the world. The scam changes, but ultimately they’re preying on the good will of people,” said Milhoan.

The most widely reported complaint was Internet auction fraud at 35.7 per cent of referred crime complaints. Other online criminal activities cited in the report include non-delivery of purchases and credit/debit card fraud, computer intrusions, spam/unsolicited e-mail, and child pornography. The report also seeks to raise awareness of other types of cyber-crimes, and describes steps individuals can take both to prevent internet crime, and to report it if they have been victimized.

A car accident involving the car occupants and a dentist’s office happened on Sunday night in Santa Ana, California. A white Nissan sedan which was apparently driving too fast hit the raised concrete median on the road, after which it was launched into the air, slamming straight into the wall of the second floor of a two-story dental practice building, where the car got wedged.

According to the police, the car approached from a side street. The room of the dental office penetrated by the sedan was used as a storage space. A fire department crane was used to extract the vehicle from the building, which took several hours.

There were two people in the sedan. One of them managed to escape from the hanging vehicle on his own, while the other one remained trapped inside it for over an hour. They were both hospitalized with minor injuries, according to the Orange County Fire Authority (OCFA). According to the police, the driver of the car admitted narcotics use, and after toxicology tests the case is to be submitted to the Orange County District Attorney’s Office.

The moment of the accident was captured by surveillance video from a bus which the car narrowly missed when becoming airborne.

According to OCFA spokesperson Captain Stephen Horner, there was a small fire after the crash, which was extinguished quickly.
