The Obamas did not pay of

15、f their student loans until Obamas best-selling books earned them millions of dollars. With the cost of a college education 1 , more than 60% of students take out loans to fund their undergraduate education. On average, students who borrow graduate with debts of $22,700a 2 of more than 18% from 2000

16、. But some of those with a newly acquired bachelors degree are restrained with debts of $40,000 or more. You think this economys tough? Try finding a job with the 3 of repaying tens of thousands of dollars in debt. Now, a new federal programIncome-Based Repaymentis making it 4 to pay back these loan

17、s. If a student chooses to repay her or his loan with this plan, payments are then readjustedbased on their income to something they can 5 afford. All debt will be forgiven after 25 years. A graduate who earns less than 150% of the 6 line wont have to make any payments. This is in addition to the ye

18、ar-old Public Service Loan Forgiveness program for those 7 in jobs such as law enforcement, public health and social work. Their loans will be forgiven after 10 years. This 8 isnt perfect; the loans have to be federal loans, not 9 . But students with more than one federal student loan can combine th

19、em under the program. In some cases, borrowers with large debt and low-to-moderate incomes may benefit at the end of 25 years, with the 10 of their debt forgiven.

Those who campaign for a green rev

21、olution are out to destroy our western lifestyles. Such are the cries of opponents of emissions cuts, and their message has political impact: a number of surveys have found that the enthusiasm of voters for policies to reduce climate change falls off as the price tag increases. However, a new modell

22、ing (模型化) exercise suggests that these fears are largely unfounded. It projects that radical cuts to the UKs emissions will cause barely noticeable increases in the price of food, drink and most other goods by 2050. Electricity and petrol costs will rise significantly, but with the right policies in

23、 place, say the modellers, this need not lead to big changes in our lifestyle.B “These results show that the global project to fight climate change is feasible,“ says Alex Bowen, a climate policy expert at the London School of Economics. “Its not such a big ask as people are making out.“ Although it

24、 is impossible to precisely predict prices four decades from now, the exercise is one of the most detailed examinations yet of the impact of climate change policies on UK consumers. It provides a useful rough guide to our economic future.C Though its results speak directly to the UK consumer, previo

25、us research has come to similar conclusions for the US. In June, one study found that if the US were to cut emissions by 50 per cent by 2050, prices of most consumer goods would increase by less than 5 per cent. The findings are also consistent with analyses by the Pew Center on Global Climate Chang

26、e in Washington DC. “Even cutting emissions by 80 per cent over four decades has a very small effect on consumers in most areas,“ says Manik Roy of the Pew Center. “The challenge is now to convince consumers and policy-makers that this is the case.“D The Intergovernmental Panel on Climate Change rec

27、ommends that wealthy nations cut their emissions to between 80 and 95 per cent below 1990 levels by 2050 in order to avoid the worst effects of climate change. The UK government aims to reduce its contribution by 80 per cent and leaders of the other G8 nations have discussed following suit. To meet

28、this goal, industries will have to cut down fossil fuel consumption, and low-carbon power sources will have to massively expand. Companies will have to pay increasingly higher prices for the right to emit greenhouse gases.E How will this affect the average citizens wallet? To measure the impact of t

29、he 80 per cent target on the UK population, New Scientist approached Cambridge Econometrics, a firm known for its modelling of the European economy. The firm used historic economic data to predict the impact of emissions reductions on prices in over 40 categories of goods and services. It compared t

30、he impact of the 80 per cent cut with a baseline situation in which the government takes no action other than the limited emissions restrictions already in place as a result of the Kyoto protocol (京都议定书).F Most of the price increases are a consequence of rising energy costs, in part because coal and

31、 gas are replaced by more expensive low-carbon sources. The price of electricity is projected to be 15 per cent higher in 2050 compared with the baseline. In todays prices, that would add around 5 onto typical monthly household electricity bills. It will also result in higher prices elsewhere, as ev

32、ery industrial sector uses electricity. But electricity and other forms of energy make up only a small part of the price of most goods. Other factorsraw materials, labour and taxesare far more important. The energy that goes into producing food, alcoholic drinks and tobacco, for example, makes up ju

33、st 2 per cent of the consumer price. For motor vehicle purchases and hotel stays, the figure is 1 per cent. Only for energy-intensive industries does the contribution climb above 3 per cent.G As a result, most products cost just a few per cent more by 2050. At current prices, going low-carbon is for

34、ecast to add around 5 pence to the price of a slice of bread or a pint of beer. The price of household appliances such as washing machines rises by a few pounds. There is one major exception to the pattern. Airlines do not currently have a low-carbon alternative to jet fuel. Unless one is found, the

35、y will bear the full burden of carbon pricing, and average fares will rise by at least 140 per cent raising the cost of a typical London to New York return trip from around 350 to 840.H Achieving the overall picture of low prices does require government action. The model forecasts that by 2050 natur

36、al gas and petrol will cost 160 per cent and 32 per cent more respectively. To avoid large price rises in home heating and road transport while still hitting the 80 per cent target, the Cambridge researchers had to build two major policies into their analysis. They assumed that future governments wi

37、ll provide grants to help switch all domestic heating and cooking to electricity, and invest in the basic facilities needed for electric cars to almost completely replace petroleum-fuelled vehicles. Both policies have been discussed in recent UK government strategy documents, though the detail of ho

38、w they would be implemented still needs further discussion. Firm policies must follow if ambitious emissions cuts are going to be made, says Chris Thoung of Cambridge Econometrics.I So is tackling climate change going to be easier than expected, in terms of consumer costs? While the Cambridge Econom

39、etrics model is widely respected and regularly used by the UK governments climate change advisers, any attempt to forecast four decades ahead can be diverted from its intended course by unforeseen events. That leads some economists to question the models results. J For example, companies could move

40、to countries with less strict carbon regulations, points out Richard Tol of the Economic and Social Research Institute in Dublin, Ireland. Incomes in the UK would fall, making goods relatively more expensive. Tol also questions whether it is reasonable to use historical prices as a basis for project

41、ing beyond 2020. Despite this, the Cambridge Econometrics results, together with other recent studies, do provide a useful guide for governments, says Michael Grubb of the University of Cambridge. They suggest that the overall challenge is conquerable, even if many of the details will only become cl
