Nuts could be the key to keeping slim, according to new research. Scientists from Harvard University and Harvard Medical School say that replacing and unhealthy snack with half a daily _____ (1) of nuts could slow weight gain in people as they get older. Walnuts ____________ (2) particular appeared to offer good results and were linked to a 15% lower risk of obesity. Researchers conducted a long-term study which followed 51,529 male health professionals aged 40 to 5, 121,700 nurses aged 35 to 55 and 16,686 nurses aged 24 to 44. Participants had their weight ____________ (3) every four years and were asked how often they had eaten nuts. They also had to report their exercise every two years. The findings, ___________________ (4) in the online journal BMJ Nutrition, Prevention and Health, showed that increasing nut consumption was associated with less risk of putting on two or more kilos over a four-year period. However, the researchers say the study is ________ (5) and therefore cannot establish a definite cause.

The International Monetary Fund (IMF) is an organization of 189 member countries.  It stabilizes the global economy in three ways. First, it monitors global conditions and identifies risks. Second, it advises its members on how to improve their economies. Third, it provides technical assistance and short-term loans to prevent financial crises. The IMF’s goal is to prevent these disasters by guiding its members. These countries are willing to give up some of their sovereign authority to achieve that aim.  The IMF has the rare ability to look into and review the economies of all its member countries. As a result, it has its finger on the pulse of the global economy better than any other organization. The IMF produces a wealth of analytical reports. It provides the World Economic Outlook, the Global Financial Stability Report, and the Fiscal Monitor each year. It also delves into regional and country-specific assessments. It uses this information to determine which countries need to improve their policies. Hence, the IMF can identify which countries threaten global stability. The member countries have agreed to listen to the IMF’s recommendations because they want to improve their economies and remove these threats.  Since the Mexican peso crisis of 1994–95 and the Asian crisis of 1997–98, the IMF has taken a more active role to help countries prevent financial crises. It develops standards that its members should follow. For example, members agree to provide adequate foreign exchange reserves in good times. That helps them increase spending to boost their economies during recessions. The IMF reports on members countries’ observance of these standards. It also issues member country reports that investors use to make well-informed decisions. That improves the functioning of financial markets. The IMF also encourages sustained growth and high living standards, which is the best way to reduce members’ vulnerability to crises.  The IMF provides loans to help its members tackle balance of payments problems, stabilize their economies, and restore sustainable growth. Because the Fund lends money, it’s often confused with the World Bank. The World Bank lends money to developing countries for specific projects that will fight poverty. Unlike the World Bank and other development agencies, the IMF does not finance projects. Traditionally, most IMF borrowers were developing countries. They had limited access to international capital markets due to their economic difficulties. An IMF loan signals that a country’s economic policies are on the right track. That reassures investors and acts as a catalyst for attracting funds from other sources. All that shifted in 2010 when the Eurozone crisis prompted the IMF to provide short-term loans to bail out Greece. That was within the IMF’s charter because it prevented a global economic crisis.  The role of the IMF has increased since the onset of the 2008 global financial crisis. In fact, an IMF surveillance report warned about the economic crisis but was ignored. As a result, the IMF has been called upon more and more to provide global economic surveillance. It’s in the best position to do so because it requires members to subject their economic policies to IMF scrutiny. Member countries are also committed to pursuing policies that are conducive to reasonable price stability, and they agree to avoid manipulating exchange rates for unfair competitive advantage.

Simmons Research conducted a survey of American adults in order to learn how much Americans at large trust the media, and we are pleased to present the results in this first Simmons News Media Trust Index. We asked respondents to let us know how trustworthy or untrustworthy they found 38 of the largest and most well-known news sources commonly available in the US. News sources included represented a wide variety of mediums, including print, online, radio, and television with many of them operating across platforms. The average percentage of respondents who rated news sources as trustworthy or very trustworthy was just 40.1% - not a ringing endorsement for journalism in general. Topping the list across all news sources, and the only newspaper in the top five, was the Wall Street Journal with 57.7% of Americans trusting them. The major television network news organizations also fared quite well in our survey, taking the second (ABC 55.9%), third (CBS 55.4%), and sixth (NBC 54.1%) most trusted positions. Among cable news, the most trusted network in the US was ironically not American. BBC News was trusted by 55.2% of Americans and was the fourth most trusted news source. CNN, which touts itself as the “most trusted name in news,” trailed the list at number 14 with the trust of 46.1% of Americans. Forbes was the most trusted magazine and rounded out the top five, trusted by 54.2% of Americans. The New York Times and the Washington Post were both among the most trusted news organizations in our survey. The New York Times came in at the seventh position trusted by 53.8% of Americans, and the Washington Post in eighth trusted by 53.6%. USA Today (51.1%) and the Washington Times (50.0%) were the final two sources trusted by at least a majority of Americans. The least trusted news sources were all Internet-first and hyper-partisan in nature representing brands that have been consistently rated as misleading and inaccurate by factcheckers. The six organizations trusted least were split evenly between far-left and far-right news sources, and on average were trusted by only about one in four Americans. Daily Caller was the bottom of our list, with just 22.5% trusting them. They were followed by another extremely conservative platform, InfoWars, at 24.3% which was recently banned or had content deleted from Facebook, YouTube, iTunes, and Spotify for violating terms of service around hate speech, harassment, and bullying

People who do not smoke, are not obese, and consume alcohol moderately can expect to live seven years longer than the general population, and to spend most of these extra years in good health, according to a new study published today in Health Affairs. This study was the first to analyze the cumulative impact of several key health behaviours on disability-free and total life expectancy. Previous studies have looked at single health behaviours. Mikko Myrskylä and his colleague instead examined several behaviors simultaneously, which allowed them to determine how long and healthy the lives of people who had avoided most of the well-known individual behavioral risk factors were. The researchers noted that each of the three unhealthy behaviours – obesity, smoking, and unhealthy consumption of alcohol – was linked to a reduction in life expectancy and to an earlier occurrence of disabilities. But there were also differences: smoking was found to be associated with an early death but not with an increase in the number of years with disability, whereas obesity was shown to be associated with a long period of time with disability. Excessive alcohol consumption was found to be associated with both decreased lifespan and a reduced number of healthy years. However, the absence of all of these risky healthy behaviors was found to be associated with the greatest number of healthy years. The most striking finding was the discovery of a large difference in average lifespan between the groups who were the most and the least at risk. Men who were not overweight, had never smoked, and drank moderately were found to live an average of 11 years longer than men who were overweight, had smoked, and drank excessively. For women, the gap between these two groups was found to be even greater, at 12 years. “Our results show how important it is to focus on prevention. Those who avoid risky health behaviours are achieving very long and healthy lives. Effective policy interventions targeting health behaviors could help larger fractions of the population to achieve the health benefits observed in this study,” the researcher emphasized. These results are important not only for individuals, but also for society. In an aging society, the health of the elderly determines the amount of money spent on the health system. In addition, healthy elderly people are better able to participate in the labor market and to perform social roles, such as caring for grandchildren.

Read the following passage and choose the best answer (A, B, C, D):
Previously, people often only considered second-hand smoke as a welfare issue, focusing on the smell and the irritation that tobacco smoke causes to eyes, nose and throat. But now the weight of evidence for much more serious risks to health from second-hand smoke has grown too great to ignore. Tobacco smoke contains around 4,000 chemicals, including arsenic, benzene, formaldehyde and ammonia. Around 60 of these chemicals are known or suspected to cause cancer. Many of the toxic chemicals are actually more concentrated in the smoke that’s given off by the burning tip of a cigarette (sidestream smoke). Around 85 per cent of the smoke in a room where people are smoking is the more toxic sidestream smoke. By breathing in it in the atmosphere, the non-smoker is exposed to many of the same health risks as the smoker. The best known risk to smokers, lung cancer, is also more common in people regularly exposed to second-hand smoke. The Government’s Scientific Committee on Tobacco and Health (SCOTH) reported in 1998 that exposure to second-hand smoke increases the risk of lung cancer in non-smokers by 20-30 per cent. Even though they inhale only 1% of the smoke, non-smokers exposed to second-hand smoke may suffer 25 per cent of the increased risk of heart disease associated with active smoking (one recent study suggests it might be as much as 50 per cent). Just 30 minutes of breathing second-hand smoke can reduce the coronary blood supply of a non-smoker to the same level as that of a smoker. A study in New Zealand found that exposure to second-hand smoke increases the risk of stroke by 82 per cent in non-smokers. This is a serious concern, as stroke is such a common condition. Moreover, around 3.4 million people in the UK have asthma and for most of these, tobacco smoke is a trigger for an asthma attack. For someone with asthma, just one hour of exposure to second-hand smoke can cause a 20 per cent deterioration in lung function. During pregnancy, breathing in second-hand smoke increases the risk of having a baby with a low birth weight. Small babies are at much greater risk of infections and other health problems. A recent review of international research on the immediate health impact of smokefree workplace legislation found rapid and dramatic improvements. Air quality, respiratory health and levels of heart attacks and heart disease all improved substantially within months of the legislation being introduced.

Read the following passage and choose the best answer (A, B, C, D):
OPEC was established at a conference held in Baghdad Sept. 10–14, 1960, and was  formally constituted in January 1961 by five countries: Saudi Arabia, Iran, Iraq, Kuwait, and Venezuela. Members admitted afterward include Qatar (1961), Indonesia and Libya (1962), Abū Ẓabī (1967), Algeria (1969), Nigeria (1971), Ecuador (1973), and Angola (2007). The United Arab Emirates assumed Abū Ẓabī’s membership in the 1970s. Gabon, which had joined in 1975, withdrew in January 1995, but it had relatively insignificant oil reserves. Ecuador suspended its membership from OPEC from December 1992 until October 2007, while Indonesia suspended its membership beginning in January 2009.  OPEC’s headquarters, first located in Geneva, was moved to Vienna in 1965. OPEC members coordinate policies on oil prices, production, and related matters at semiannual and special meetings of the OPEC Conference. The Board of Governors, which is responsible for managing the organization, convening the Conference, and drawing up the annual budget, contains representatives appointed by each member country; its chair is elected to a one-year term by the Conference. OPEC also possesses a Secretariat, headed by a secretary – general appointed by the Conference for a three-year term; the Secretariat includes research and energy-studies divisions.  OPEC members collectively own about two-thirds of the world’s proven petroleum reserves and account for two-fifths of world oil production. Members differ in a variety of ways, including the size of oil reserves, geography, religion, and economic and political interests. Four members – Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates – have very large per capita oil reserves; they also are relatively strong financially and thus have considerable flexibility in adjusting their production. Saudi Arabia, which has the largest reserves and a relatively small (but fast-growing) population, has traditionally played a dominant role in determining overall production and prices Because OPEC has been beset by numerous conflicts throughout its history, some experts have concluded that it is not a cartel – or at least not an effective one – and that it has little, if any, influence over the amount of oil produced or its price. Other experts believe that OPEC is an effective cartel, though it has not been equally effective at all times. The debate largely centers on semantics and the definition of what constitutes a cartel. Those who argue that OPEC is not a cartel emphasize the sovereignty of each member country, the inherent problems of coordinating price and production policies, and the tendency of countries to renege on prior agreements at ministerial meetings. Those who claim that OPEC is a cartel argue that production costs in the Persian Gulf are generally less than 10 percent of the price charged and that prices would decline toward those costs in the absence of coordination by OPEC.  The influence of individual OPEC members on the organization and on the oil market usually depends on their levels of reserves and production. Saudi Arabia, which controls about one-third of OPEC’s total oil reserves, plays a leading role in the organization. Other important members are Iran, Iraq, Kuwait, and the United Arab Emirates, whose combined reserves are significantly greater than those of Saudi Arabia. Kuwait, which has a very small population, has shown a willingness to cut production relative to the size of its reserves, whereas Iran and Iraq, both with large and growing populations, have generally produced at high levels relative to reserves. Revolutions and wars have impaired the ability of some OPEC members to maintain high levels of production.

The number of people accessing the State’s and community’s priority policies and  programmes is increasing, said Minister of Labour, Invalids and Social Affairs Dao Ngoc Dung. Vietnam has around 6.2 million people over the age of two with disabilities, making up 7.06 per cent of the country’s population. Of those, 28 per cent are severely disabled, 58 per cent female, 28 per cent children and 10 per cent living in poverty. Most live in rural areas and many are victims of Agent Orange.  Minister Dung said in the past, the State, the Party and Vietnamese people had paid much care to people with disability. Vietnam ratified the United Nations’ Convention on the Rights of People with Disability in 2014. In March this year, the country ratified the International Labour Organisation’s Convention 159 about jobs for people with disability. It strongly confirmed Vietnam’s commitment ensuring the disabled would not be discriminated at work.  Last month, the Secretariat Committee issued the Instruction 39 about the Party’s leading work on affairs related to people with disability. The National Assembly later ratified the amended Law on Labour with many adjustments relating to disabled people. Dung said that every year, millions of disabled people receive an allowance from the State and all of provinces and cities had rehabilitation centres. Attending the event, Truong Thi Mai, head of the Party Central Committee’s Commission for Mass Mobilisation, said besides the achievements, Vietnam still sees many obstacles. Infrastructure is still limited demand for people with disability and many live below the poverty line depending heavily on their families.  Mai asked organisations to improve education to raise people’s awareness of the meaning of supportive work to people with disability. This year, more than VNĐ17 trillion (US$735.4 million) from the State budget was allocated to provinces and cities to implement policies for people with disability, according to the Ministry of Labour, Invalids and Social Affairs.  The Ministry of Planning and Investment on Thursday launched the programme “White stick for Vietnamese visual impaired people”. Its aim is to present one million white sticks to visually impaired people across the country. Training to use the device will also be provided. Minister of Planning and Investment Nguyen Chi Dung said the ministry will listen to disabled people’s demands and wishes and put them into its policies. Deputy chairwoman of the National Assembly Tong Thi Phong said Vietnam has committed to developing socioeconomy, taking care of social equality and improving social management ability.

The era of “smart cities”, controlled by an ecosystem of sensors, cameras and  algorithms, is fast approaching. In China, state media claim 500 are under construction. In Canada, Alphabet has plans for turning parts of Toronto into a timber-framed tech town as a prototype. Incremental steps are also making cities smarter. Last week, Transport for London announced plans to track Tube passengers through WiFi to monitor congestion. In the US, fast-food drive-throughs will trial number plates scanners to make ordering faster. Individually these services can improve daily life. Integrating them will create something more powerful than the sum of its parts.  Though convenience and safety are the end goals, serious questions about how city authorities will both store and share vast bodies of data must be answered. The fact that surveillance is built into key transport infrastructure will also make it increasingly difficult to avoid without disrupting daily life. The smart city risks creating a panopticon in the name of an easier and better life. The risks of anonymity disappearing will be increased by the use of different data sets, making it more likely that identifiable characteristics may appear. Closely linked to this is the question of data storage and sharing. The treasure trove of personal information will be a tempting target for hackers. This information might also be used by law enforcement, feeding into the existing dangers of mass surveillance and profiling, as is already the case in China.  These concerns have long been levelled at social media and internet-enabled home appliances. Smart city surveillance can be even more insidious. Users can avoid Facebook or hardware such as Alexa. Avoiding basic infrastructure will be near impossible without seriously affecting day-to-day life. TfL has put up signs warning customers of the WiFi tracking, yet the only choice is between tracking and having no signal. Reports on the facial recognition at airports in America suggest that avoiding being automatically scanned will be tough as well. As these systems become more closely enmeshed, avoiding snooping will become increasingly tricky.  The inevitable rise of smart cities is not inherently negative. Harnessing the power of technology and data can potentially help urban environments adapt to challenges such as climate change and overcrowding. Politicians, programmers and academics must work to ensure that does not come at the cost of all-seeing, 24-hour surveillance.

Though overwhelmed by the news of the novel coronavirus outbreak, Munyaradzi Gurure, the 21-year-old student at Guangxi University of Finance and Economics from South Africa, has still stepped out to serve as a volunteer in the train station to help battle the epidemic.  “I’m well aware the situation of epidemic prevention and control is very severe,” he said. “Seeing that many people actively joined in the fight, I also wanted to do my part and volunteer at the station.” With the number of novel coronavirus cases continuing to rise both in and outside of China, Gurure’s family back in South Africa was very worried about his health, and hoped he would quit the volunteer job. “I told my parents China has taken a lot of strong quarantine measures and is actually safe,” he said. “I want to do whatever I can to prevent the spread of the infection. The country took really good care of me during the last three years.”  Working about four hours a day, Gurure either carries an 8-kilogram electric sprayer to disinfect the waiting room or checks passengers’ temperature as soon as they walk into the station. He also makes sure people are in good health and wearing masks at all times. Though it’s not easy work, Gurure came across many Chinese who are very surprised to see a foreign face, but then give a thumbs up and say “very good” to him in Chinese. Gurure’s foreign classmates found out about his volunteer job and sent messages saying “good job”, some showing interest in joining him to help curb the spread of the virus.

Hidden beneath the waves of the Tyrrhenian Sea near southwestern Italy lies a newfound volcanic mosaic dotted with geothermal chimneys and flat-topped seamounts. This complex is new to both science and the planet, geologically speaking; it’s only about 780,000 years old. Scientists aren’t particularly surprised to find volcanism in the region, which is home to active volcanoes like Mount Vesuvius and Mount Etna. But the new complex is unusual because it was created by a rare kind of fault, said study leader Fabrizio Pepe. The western Mediterranean is seismically restless because of the collision of three tectonic plates: the African, the Eurasian and the Anatolian. Making matters more complex is a small chunk of crust called the Adriatic-Ionian microplate, which broke off of the African Plate more than 65 million years ago and is now being pushed under the larger Eurasian Plate in a process called subduction. Previously, scientists discovered a series of undersea volcanic arcs created by this tectonic unrest, starting near the Sardinian coast, with increasingly younger arcs southward and eastward. These arcs were like an arrow pointing ever farther eastward, prompting Pepe and his colleagues to search for an even younger arc about 9 miles off the coast of Calabria. There, based on seafloor mapping, seismic data and magnetic anomalies, the researchers found a 772-square-mile region of lava flows, volcanic mountains and hydrothermal chimneys; vents in the seafloor allow hot minerals to spew out and form chimney-like structures. They dubbed the new area the Diamante‐Enotrio‐Ovidio Volcanic‐Intrusive Complex, after three flat-topped seamounts that dominate the seafloor. Those fractures are what allowed magma to rise to the surface at the Diamonte-EnotrioOvidio complex, creating an undersea landscape of lava flows and mountainous volcanoes. These volcanic seamounts are now plateaus because they protruded from the ocean when the sea level was lower, and they eroded into their present, flat-topped shape, Pepe said. The volcanic complex is inactive, but there are small intrusions of lava in some parts of the seafloor there. However, the area could become active in the future, Pepe said, and active volcanism is ongoing on the eastern side of the Tyrrhenian Sea. The researchers are working to build a volcanic risk map of the complex to better understand if it could endanger human life or property. They are also investigating the possibility of tapping the complex to produce geothermal energy.

When it comes to cooking, boomers cook one, Generation X cooks another way and the beat generation does things that must be recorded now, because once they have passed out of fashion, they will never be discovered again. They have weird skills, derived from scarcity in their early years. They keep their spices in brown glass because they last longer. For practical purposes, this means everything is in an old Calpol bottle with “sumac” scrawled over it. Some of them are, and will fish an empty packet of sugar out of the bin, shake a quarter-teaspoon of sugar from it and put it back. They can often make a cake by eye, without weighing anything, which I find incredible, and they know what to do with leaf gelatine, which is great until it isn’t. My mother once made avocado in jelly and then said: “I don’t know, the proportions may have been slightly off.” I said, recklessly: “Don’t worry – I’m sure I’ll choke it down,” but when it came to it, my cutlery bounced off it, like a prank played on a very hungry person in a cartoon. The beat generation canon is Meat at Any Price and Fish at Any and anything to do with mince. The descent of mince from a sacred food to a bolognese-only staple is one of the great mysteries of progress, because it is delicious even when you don’t shove a load of tomato in it. But you can’t just shove cheap meat in a pan and watch while it sweats out watery grey juice. This seems to be something that only wartime generations understand. Hip parents in the 70s, or regular parents in the 80s, or quite trad parents in the 90s had a horror of overcooked carrots and waterlogged cabbage. The very smell of cooked vegetables evoked for them every bad memory of British cuisine, before anchovies and Italians and radicchio arrived, when all dinner was a school dinner. So they would all just tease their vegetables with a hint of boiling water, before turning them out, still basically a salad, only a bit warmer. Then you, their offspring, would leave home, and accidentally encounter a vegetable that had been cooked, and realise how delicious it was and now you probably overcook your vegetables a bit, and your children will go the other way.

Stabilisation work means the Leaning Tower of Pisa is leaning slightly less than it used to, experts have said. The tower, which has leaned to one side ever since it began to take shape in 1173, has lost 4cm of its tilt over the past two decades, according to a report from the surveillance group that meets every three months to give updates on the monument’s condition “Since restorative work began, the tower is leaning about half a degree less,” said Nunziante Squeglia, a geotechnics professor at the University of Pisa who works with the group. “But what counts is the stability of the tower, which is better than initially predicted.” The structure, which was badly damaged during the second world war, was closed to the public in 1990 over safety fears and did not reopen for 11 years. The surveillance group was set up in 2001 ago after Michele Jamiolkowski, an engineer of Polish origin, coordinated an international committee to save the landmark. The bell tower, a symbol of the power of the maritime republic of Pisa in the Middle Ages, was defective from the beginning due to the porous clay soil beneath its foundations. After three floors were completed, construction stopped and did not resume until 90 years later when workers started building additional floors on a diagonal to offset the lean. But work was again disrupted before finally being completed in 1372. The tower, located behind Pisa’s cathedral, attracts more than 5 million visitors a year. Reaching the top requires climbing 269 steps. The surveillance group’s work, which is funded by the non-profit Opera della Primaziale Pisana, includes improving the quality of the structure’s conservation and promoting research.

The fresh data released by the Centre for Monitoring Indian Economy (CMIE)  showed that unemployment rate in the month of October jumped to 8.5 per cent, which is the highest in over three years. A new academic research paper released by the Centre of Sustainable Employment also concluded that there has been a marked decline in total employment in India between 2011-12 and 2017-18, reported The Indian Express.  The research paper by Santosh Mehrotra and Jaiati K Parida stated as, "However, due to sharp increases in enrollment at every level of education over the noughties, it was expected that post -2012 total employment would increase, particularly in the non-farm sectors. But unfortunately, total employment during 2011-12 and 2017-18 declined by 9 million. The research further states that this happened for the first time in India’s history.  It is really ironical noting that Coimbatore Municipal Corporation posted a vacancy for 549 sanitary workers. What followed was that 7000 highly qualified applicants even some of them with engineering and graduate degrees applied for the job. The Corporation witnessed the overwhelming turnout of 7000 candidates. Similarly, few month back, Chennai witnessed an unusual event when around 4600 of youth sent their application for 14 posts like sweepers and sanitary workers. The applicants had professional qualification like B.Tech, M.Tech, Master of Business Administration.  Though the government constantly has been refuting the grim of job data but the facts and figures can’t be avoided any more. Therefore, now the government should take an initiative to overcome the high prevalence of unemployment and figure out the derivers of the job crisis. In this regard, it is worth to mention a book titled ‘Job crisis in India’ written by business journalist Raghavan Jagnnathan. The author in his book pointed out factors and reasons behind this decline of employment. He attributed that the absence of skills required in the highly technical nature of jobs is big factor. Another aspect of this is that in the majority of cases the skills or training acquired by the youths do not match or suit the core demand of the job. So at first the government must step up for reformation, innovation and renovation of the standard of the education in universities and colleges.

The temperature of the earth is rising at nearly twice the rate it was 50 years ago. This rapid rate and pattern of warming, scientists have concluded, cannot be explained by natural cycles alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans. To come to a conclusion on climate change, the United Nations formed a group of scientists called the Intergovernmental Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists. One of the first things the IPCC learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture, especially from the digestive systems of grazing animals, nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2. Different greenhouse gases have very different heat-trapping abilities. Some of them can even trap more heat than CO2. A molecule of methane produces more than 20 times the warming of a molecule of CO2. Nitrous oxide is 300 times more powerful than CO2. Other gases, such as chlorofluorocarbons, or CFCs, which have been banned in much of the world because they also degrade the ozone layer, have heat-trapping potential thousands of times greater than CO2. But because their concentrations are much lower than CO2, none of these gases adds as much warmth to the atmosphere as CO2 does. In order to understand the effects of all the gases together, scientists tend to talk about all greenhouse gases in terms of the equivalent amount of CO2. Since 1990, yearly emissions have gone up by about 6 billion metric tons of “carbon dioxide equivalent” worldwide, more than a 20 percent increase.
