In 1896, Swedish scientist Svante Arrhenius explored whether Earth’s temperatures were influenced by the presence of heat-absorbing gases in the atmosphere. He calculated that if carbon dioxide concentrations doubled, global temperatures would rise by 5°C – even more at the poles. According to a team of researchers in Australia the world is on track to fulfilling Arrhenius’ prediction. If we continue the current trajectory, Earth will warm up to 4.8°C above pre-industrial times by 2100. They examine four fronts to battle the climate change: Plant a lot more trees, Turn carbon dioxide into rock, Make Earth’s surface more reflective, Reimagine transport. Some technologies may prove too costly, too risky, or too slow to implement. All require careful governance, leadership and public engagement to ensure community backing…read more.
