At the UN climate change summit in Paris this week multiple countries are demanding that the 2°C goal of limiting global warming be discarded – and replaced with the more ambitious target of 1.5°C.
Ministers from across the globe appear to have been persuaded that a 2°C rise would be catastrophic for many countries in low-lying or hot regions.
According to research carried out in preparation for the Paris summit, 1.5°C of warming was vastly preferable to 2°C. A large number of scientists still believe the 1.5°C target is achievable with radical action, lending credibility to calls for a tougher target.
Low-lying and hot regions are not the only areas that would be threatened even if global warming were limited to less than 2°C but more than 1.5°C. This is because the temperature increases associated with climate change are set to be unlikely, with the largest changes set to be in the Arctic.
