Effects of climate change on US grain transport

Climate-induced shifts in crop mix may affect the grain transport system. In the US, evidence now shows that changing crop mixes reduce the importance of Lower Mississippi River ports, but increase the role of ports in the Pacific Northwest, Great Lakes and Atlantic.

Intensification of winter transatlantic aviation turbulence in response to climate change

Most weather-related aircraft incidents are caused by atmospheric turbulence; however, the effects of changing climate are not known. Climate model simulations show that clear-air turbulence, associated with jet streams, changes significantly for the transatlantic flight corridor when atmospheric carbon dioxide is doubled. These results suggest that climate change will lead to bumpier transatlantic flights by the middle of this century.

Guilt trip

As the evidence for a tight link between greenhouse-gas emissions and climate change accrues, scientists — and editors — should moderate their use of international air travel.

Realizing the electric-vehicle revolution

Substantial work has shown the potential energy and climate benefits of full battery electric vehicles (BEVs) — an important policy option to mitigate climate change — but there are still uncertainties about their market diffusion. Research shows the importance of assessing BEV diffusion from an integrated perspective, focusing on the interaction between technology and behaviour.

Policy: A challenging future for cars

The rising demand for road vehicles increases Europe's oil dependency and carbon emissions. Switching to alternative cars and fuels can help energy security and climate change policy, if consumers can be persuaded.

Divergent long-term trajectories of human access to the Arctic

Subzero temperatures at high latitudes typically restrict shipping but facilitate ground transportation. A study quantifies the impacts of climate change on Arctic transportation by mid-century and finds that all eight Arctic states will probably suffer steep declines in inland transport, but will reap the benefits of faster sea travel.

Mitigation: A sweetener for biofuels

The climate impact of biofuels is usually considered in terms of their net effect on greenhouse-gas emissions. The expansion of sugar cane into pastureland for biofuel production is now shown to also exert a direct local cooling effect.

Global radiative forcing from contrail cirrus

Aviation is known to affect climate by changing cloudiness, but the magnitude of this effect remains uncertain. A modelling study indicates that changes in cloudiness associated with spreading of the line-shaped contrails that form behind aircraft may cause almost an order of magnitude more warming than the contrails alone.

Atmospheric science: Seeing through contrails

Contrails formed by aircraft can evolve into cirrus clouds indistinguishable from those formed naturally. These 'spreading contrails' may be causing more climate warming today than all the carbon dioxide emitted by aircraft since the start of aviation.
