Get the government to support a world ban on oil exploration in the arctic.
Oil exploration will have disastrous impacts on the environment. As the ice retreats it is more likely people will take to oil exploration which would lead to further melting of the ice. It's a vicious circle! The acceleration of the melting of arctic ice would not only release vast amount of methane trapped in the ice into the atmosphere but less ice means that less heat will be reflected and more would be absorbed as the darker coloured sea and land is left in place. There will be a massive impact on wildlife, sea level rise and potential hazards to the gulf stream as fresh water is released etc. This is all before the risk of oil spillage etc
