　　As it is, sleep is so undervalued that getting by on fewer hours hasbecome a badge o?

It’sno surprise, then, that more than half of American adults get the 7 to 9 hoursof shut-eye every night as 37 by sleep experts.

　　Whether or not we can catch up on sleep – on the weekend, say- is ahotly 38 among sleep researchers.

　　Climatechange may be real, but it’s still not easy being green

　　How do we convince our inner cavemanto be greener?We ask some outstanding social scientists.

　　A) The road to climatehell is paved with our good intentions. Politicians may tackle polluters whilescientists do battle with carbon emissions. But the most pervasive problem isless obvious: our own behaviour. We get distracted before we can turn down theheating. We break our promise not to fly after hearing about a neighbor’s ripto India. Ultimately, we can’t be bothered to change our attitude. Fortunatelyfor the planet, social science and behavioral economics may be able to do thatfor us.

　　B) Despite mournfulpolar bears and carts showing carbon emissions soaring, mot people find it hardto believe that global warming will affect them personally. Recent polls by thePew Research Centre in Washington, DC, found that 75-80 per cent ofparticipants regarded climate change as an important issue. But respondentsranked it last on a list of priorities.

　　C) This inconsistencylargely stems from a feeling of powerlessness. “When we can’t actually removethe source of our fear, we tend to adapt psychologically by adopting a range ofdefense mechanisms,” says Tom Crompton, change strategist for the environmentalorganization World Wide Fund for Nature.

　　D) Part of the faultlies with our inner caveman. Evolution has programmed humans to pay mostattention to issues that will have an immediate impact. “We worry most aboutnow because if we don’t survive for the next minute, we’re not going to bearound in ten years’ time,” says Professor Elke Weber of the Centre forResearch on Environmental Decisions at Columbia University in New York. If theThames were lapping around Big Ben, Londoners would face up to the problem ofemissions pretty quickly. But in practice, our brain discounts the risks—andbenefits—associated with issues that lie some way ahead.

　　E) Matthew Rushworth,of the Department of Experimental Psychology at the University of Oxford, seesthis in his lab every day. “One of the ways in which all agents seem to makedecisions is that they assign a lower weighting to outcomes that are going tobe further away in the future,” he says. “This is a very sensible way for ananimal to make decisions in the wild and would have been very helpful forhumans for thousands of years.”

　　F) Not any longer. Bythe time we wake up to the threat posed by climate change, it could well be toolate. And if we’re not going to make national decisions about the future,others may have to help us to do so.
