If country leaders manipulate the weather to do their bidding, could they create political tensions, or even all-out war?
Climate change is a problem in desperate need of a solution. According to the authoritative Carbon Action Tracker, even if all nations honour their pledges to cut their greenhouse gas emissions, the globe will still warm by around 3.2°C by 2100 – with catastrophic consequences for humanity and the animal kingdom.
If cutting greenhouse gas emissions isn’t enough, is it time for a plan B? Recent times have seen a surge of interest in geoengineering: China has recently embarked on a substantial research plan, while in the US, Prof David Keith of Harvard University is planning to launch a high-altitude balloon this year to test the feasibility of spraying reflective particles into the stratosphere. Meanwhile, other researchers are looking at the possibility of increasing the brightness of marine clouds to reflect more sunlight back into space.
But there are a number of risks, and not just because we’re unsure about how effective these interventions would be. There are fears that one country’s efforts to solve its climate problem could inadvertently mess up the weather elsewhere, creating a new source of political tension. And ultimately, this leads to a worrying question: could we be looking at the dawn of a new kind of war – one fuelled by a battle for dominance over our planet’s climate system?
