1.5 v 2 Degrees Celsius: Why Half a Degree Really Counts

29th April 2021 @ 9:00 am - 5:00 pm

In this free livestreamed event, campaigners and experts will debate how best to tackle the challenge of Earth’s rising temperature.

The persistent march of a warming climate is perceived as incremental changes. But the greater the change in global temperature, the higher the risk that the cumulative impact of all these changes could cross a tipping point of dramatic and irreversible climate change.

Earth is already one degree hotter than at pre-industrial levels and we are already seeing unprecedented melting of polar ice, wildfires, extreme weather and widespread extinctions. The 2015 Paris Agreement commits nations to limiting the rise to 1.5 degrees Celsius or to 2 at the very most. If we pass this point, we increase the risk that the Earth’s climate system changes abruptly and for the worse.

But what is the science behind how we model our current trajectory, how do we shape our responses to the urgent threat, and how is climate change affecting communities across the globe already? At this online event, a panel of campaigners and experts in climate science and policy come together to plot out the various scenarios and how best to tackle the challenge.

Speakers include:

• Anote Tong: Former President of the Republic of Kiribati, twice nominated for the Nobel Peace Prize and a world-renowned campaigner against climate change and for ocean conservation.
• Cassidy Kramer: A member of the Alaskan Inupiaq community, enrolled in the Caleb Scholars programme, which advocates for protecting Arctic waters through ancestral knowledge.
• Professor Sir Ghillean Prance FRS, VMH: Botanist, ecologist, former Director of the Royal Botanic Gardens in Kew, and Visiting Professor, University of Reading
• Julia King, Baroness Brown of Cambridge: Deputy Chair of the UK Committee on Climate Change, the UK’s Low Carbon Business Ambassador and Chair of the Carbon Trust.
• Mark Lynas: Environmental journalist and author of several books including Our Final Warning: Six Degrees of Climate Emergency
• Anushka Asthana: Editor-at-large for the Guardian, presenter of the Guardian Today in Focus podcast and co-presenter of Peston.

This online event is part of the Science Museum Group’s series of Climate Talks. The event is free but booking is essential. Recommended for ages 14+.
