Our planet is in peril, and we can no longer dodge the arrival of disastrous, all-pervasive, climate breakdown that will come as a hammer blow to global society and economy. Bill McGuire, professor of geophysical and climate hazards at University College London, offers a post-COP26 perspective on the climate emergency, acknowledging that it is now practically impossible to keep this side of the 1.5°C dangerous climate change guardrail, and presenting a blunt but authentic picture of the sort of world our children will grow old in, and our grandchildren will grow up in. In conversation with Jane Davidson, Chair of Wales Net Zero 2035, Pro Vice-Chancellor Emeritus at the University of Wales Trinity Saint David and author of #futuregen: Lessons from a Small Country.
