Current greenhouse gas emissions could raise temperatures by 3 degrees Celsius (ºC), according to Thelma Krug, vice-chair of the Intergovernmental Panel on Climate Change. The limit for warming, she says, is "the lower the better." The October 2018 IPCC report already warned of climate change if states allow temperatures to exceed 1.5ºC compared to pre-industrial times.
"Today, if we add up all the contributions made by all countries, we are well on track for 3°C of warming, practically double what we would be aiming for to minimize potential impacts. The scientists' message is very clear: it would be much better if we began a major transformation in all sectors, aiming to significantly reduce greenhouse gas emissions," said the IPCC vice-chair.
