So planet Earth has reached a kind of breaking point – a 12-year deadline for humans to put a lid on rising temperatures or face devastating consequences. This week the United Nations Intergovernmental Panel on Climate Change (IPCC) made the most daring and most profound declaration in its history: that by 2030, earth’s temperature is set to warm by 1.5C, and that is the maximum that the planet can withstand. That maximum can and will be breached if there is no change and, if so,our world faces certain disaster, on a grand scale.
