    The war on Iran has put fossil-fuel prices centre stage, but don’t believe those who tout ‘maximising the North Sea’ as our salvationThese are burning, smoking lies. As oil and gas prices soar, thanks to the US and Israel’s attack on Iran, the UK’s opponents of climate policy become even shriller.

  • How Toronto's snow mountains hide a toxic secret – video

    The Guardian reporter Leyland Cecco visits an almost 100ft-tall snow mountain, one of six created in Toronto to store all the snow cleared from roads and paths across the city.Toronto has spent more than C$1bn dollars over a decade to successfully re-naturalise the mouth of the Don River. But this is at risk because the salt contained in the snow mountains is likely to end up in water systems, causing an 'ecological crisis'.More than 130,000 tonnes of salt were used during the winter's record sn
