A retired parole officer in his eighties was among climate change protesters arrested on 25 April, after climbing on top of a train in London’s rush hour. Extinction Rebellion want politicians to realise that climate change is actually a ‘climate crisis’. The following are twitter suggestions by environmentalists for transformation: cancel Heathrow expansion and impose graduated taxes on frequent fliers; insulate UK's draughty housing stock; and make electric cars work. They say the Department for Transport is failing to deliver a vitally important charging network as part of its long-term climate plans. Other suggestions are: get farmers to cut emissions, and start widespread rewilding so that trees can capture CO2; stop tax breaks to North Sea oil and gas; ban fracking; and bring back cheap, effective onshore wind power. Many said if we really want to tackle climate change we should be going as fast as we can, not setting arbitrary target dates like 2050.
