So how different would the impacts of climate change be at 3☌ compared to 1.5☌?Īt the outset, it is important to point out that – even if impacts increased in line with temperature – the impacts at 3☌ warming would be more than twice those at 1.5☌. No wonder that nearly two thirds of Intergovernmental Panel on Climate Change (IPCC) authors who responded to a new survey conducted by the journal Nature expect the increase to be 3☌ or more.
However, even if countries fulfilled their current pledges to reduce emissions, we would still see an increase of around 2.7☌. In the Paris Agreement, countries committed to seek to limit the increase in temperature to 1.5☌ above pre-industrial levels.
