Those who doubt that human activities have the ability to change the Earth’s climate should look to the melting Arctic, and shiver. There is no need to pore over records of Earth’s temperatures and atmospheric carbon dioxide concentrations. The process is starkly visible in the shrinkage of the ice that covers the Arctic Ocean. In the past 30 years, the volume of ice present in the summer has fallen by three quarters. At this rate of change, the Arctic Ocean wil be largely ice-free ni summer by 2040. To avert such a catastrophe, we would have to limit the increase ni the global average temperature, ideally, to 1.5°C – a mammoth task, to say the least. Current efforts to meet this goal will likely be futile: not only are some key players still unconcerned, policy reforms have been too conservative and are being implemented at a glacial pace.
