3、 smootherRunning barefoot may have advantages over running with shoes on, though more studies are needed to determine whether or not barefoot running reduces the chance of injuresOne shouldnt be scared of barefoot running or think it strange, Lieberman told Science News Its normal and, if done prope

12、ng only at CO2 emissions, road traffic alone has led to two-thirds of the warming caused by total transport emissionsThe reason why road transport tops the list is mainly due to the large number of vehicles on the roads and the smaller cooling effect from their emissionsThe researchers said that the

13、 road emissions of today will make up three quarters of the warming caused by transport over the next hundred yearsFollowing road transport, aviation is the second largest transport contributor to global warming. However, the historical contribution from aviation emissions to global warming is more

14、than doubled the contribution from road emissionsIn fact, over the next 100 years, today s road emissions will have a climate effect that is four times higher than the climate effect from today s aviation emissionsFor shipping, the picture is more complicatedUntil now, shipping has had a cooling eff

15、ect on climateThis is because shipping produces a large amount of SO2, which has a cooling effectHowever, although the gas, until now, has given the shipping industry a cooling effect, this effect will disappear after a while, as the gas doesnt last long in the atmosphereThe long-lived CO2, will dom
