The amount of gas used means that a barrel of Californian heavy oil gives the stuff from Canada's tar sands a run for its money in terms of associated greenhouse-gas emissions.
To have a two-thirds probability of meeting the 2C target, total CO emissions between 2011 and 2100 have to be less than 950bn tons.
The train's only emissions are steam and water, resulting in minimal impact to the environment.

" "The sooner we take action on global greenhouse gas emissions and transition away from fossil fuels to renewables, the better.
Li said that scientists have believed for a long time that the acid produced by human activity and emissions can allow the insoluble iron oxide to convert into soluble iron, and if the particle settles on the surface of the ocean, it can allow the organisms on the surface of the ocean to effectively use iron and encourage the growth of marine microorganism.
