CAPE TOWN – In 2015, the landmark Paris climate agreement set the ambitious but necessary goal of limiting global warming to 1.5° Celsius above pre-industrial levels, and ensuring that the increase stays “well below” 2°C. With the average global surface temperature having already reached 1.1°C (1.98°F) above the twentieth-century baseline, time is running out to reach this goal. Yet governments have so far failed to agree on a strategy for doing so.
