The IPCC Report: Key Findings and Radical Implications
Beyond the headlines: what climate science now shows about Earth’s future. Can we act in time?
The UN-sponsored Intergovernmental Panel on Climate Change (IPCC) recently released its latest comprehensive report on the state of the earth’s climate. The much-anticipated report dominated the headlines for a few days in early August, then quickly disappeared amidst the latest news from Afghanistan, the fourth wave of Covid-19 infections in the US, and all the latest political rumblings. The report is vast and comprehensive in its scope, and is worthy of more focused attention outside of specialist scientific circles than it has received thus far.

It removes several elements of uncertainty from the climate picture, including some that have wrongly served to reassure powerful interests and the wider public that things may not be as bad as we thought.

First some background. Since 1990, the IPCC has released a series of comprehensive assessments of the state of the earth’s climate, typically every 5–6 years. The reports have hundreds of authors, run for many hundreds of pages (this one has over 3000), and represent the international scientific consensus that has emerged from the period since the prior report…
