According to the scientific study, the reef could become a "dead ecosystem" with mass bleaching likely happening every two years by 2034 unless Australia does its bit to curb global greenhouse emissions. Last week, 170 tourism operators wrote to several politicians, including the prime minister, the federal environment minister and local representatives, pleading urgent climate action to save the reef.

The Royal Swedish Academy of Sciences' recent decision to award the 2019 Nobel Prize in Chemistry to scientists who developed rechargeable lithium-ion batteries reminded the world just how transformative they have been. Without them, we wouldn't have smartphones or electric cars. But it's their potential to store electricity generated by the sun and the wind at their peak that promises to be even more revolutionary, reducing our dependence on fossil fuels and protecting the planet from the worst consequences of climate change.
