Storms are becoming more intense as the climate changes. This is just one reason why the signing of the Paris Agreement by 170 nations in New York last week is great news. Finally, there is a sense of momentum; a shared purpose worldwide that the rate of climate change urgently needs to be slowed down. The next—and most important—step is for countries to ratify the treaty and enshrine the agreement in national legislation. Let’s all hope this progresses smoothly and quickly.
