IPCC 1.5°C report: here’s what the climate science says
The IPCC report focuses on climate change and the impact on ecosystems. If we want to limit human-induced global warming to 1.5°C we probably can. The IPCC report identifies various routes by which emissions cuts would limit warming to 1.5°C; each makes assumptions about future changes in, for example, economic strategy, population growth and the rate at which low carbon energy is adopted.
On the brink of catastrophe
The latest report by the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC) released on 8 October 2018 says that urgent and unprecedented changes are needed to reach the target of restricting global warming to a maximum of 1.5°C, beyond which, even half a degree will significantly worsen the risk of droughts, floods, extreme heat and poverty for much of the world’s population.
