Urgent action is needed to limit global warming to 1.5 degrees Celsius above preindustrial levels, the Intergovernmental Panel on Climate Change has warned.
In a report published on 8 October, the panel said “rapid, far-reaching and unprecedented changes in all aspects of society” were required in order to meet the targets set by the Paris agreement on climate change in 2015.
The report estimates that to meet the target, net global, human-caused emissions of carbon dioxide will need to fall by about 45 per cent from 2010 levels by 2030, reaching “net zero” around 2050.
