The recent report of the UN Intergovernmental Panel on Climate Change, Climate Change 2021: The Physical Science Basis, is not a happy read.
The IPCC report provides new estimates of the chances of crossing the crucial global warming level of 1.5°C in the coming decades. It finds that “unless there are immediate, rapid, and large-scale reductions in greenhouse gas emissions, limiting warming to close to 1.5°C or even 2°C will be beyond reach.” A 1.5°C increase in global warming is believed to be the point at which climate change would be irreversible. To quote the report’s chief author, Joeri Roejl, PhD, “The greater weight of evidence has confirmed the trend, as expected, and it’s not really good news.”
