OSAKA ¨C In October 2018, the Intergovernmental Panel on Climate Change (IPCC) released a report that sent shock waves around the globe. The world¡¯s leading body of climate scientists warned that there might be only 12 years left to ensure global warming is kept to a rise of 1.5 degrees Celsius. Beyond that, the IPCC said, the risk of droughts, floods and extreme heat greatly increase.
¡°Limiting global warming to 1.5 degrees would require rapid, far-reaching and unprecedented changes in all aspects of society,¡± the report said.
The 1.5 degree figure represents the ideal goal under the 2015 Paris climate change agreement. Nations pledged to respond to the threat of global warming by ¡°holding the increase in the global average temperature to well below 2 degrees Celsius above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 degrees Celsius above pre-industrial levels.¡±
