Singapore's twin imperatives for climate action

Step up climatic defences, and replace fossil fuels with renewable energy


The continued rise in carbon emissions worldwide, which hit 415 parts per million (ppm) in May, is boosting global temperatures alarmingly. Singapore's warmest days this year exceeded 34 deg C, compared with a 27 deg C average in the 1960s. The top concern at global fora like the recent Group of Seven meeting should have been runaway climate change. And countries, including Singapore, must switch rapidly from polluting fossil fuels to renewable energy, while building climate defences.

Brazil, under President Jair Bolsonaro, is allowing unprecedented deforestation of the Amazon rainforest, which holds 20 per cent of the world's source of oxygen.
