Every country in the world is seeing the drastic effects of climate change, some more than others. On average, the annual losses just from earthquakes, tsunamis, tropical cyclones and flooding count in the hundreds of billions of dollars. We can reduce the loss of life and property by helping more vulnerable regions—such as land-locked countries and island states—become more resilient. It is still possible, with the political will and technological measures, to limit the increase in global mean temperature to two degrees Celsius above pre-industrial levels— and thus avoid the worst effects of climate change. The Sustainable Development Goals lay out a way for countries to work together to meet this urgent challenge.
