Public Talk: Microbes and climate change. Part 2 – Methane and nitrous oxide by Dr Paul Broady

Event date:
Event location:

WEA, 59 Gloucester Street (op. Art Gallery), Christchurch
New Zealand

Event type:
Public talk
Conservation area:

In Part 1, we looked at how microbes on a global scale influence concentrations of carbon dioxide in the atmosphere, both by absorbing and producing the gas. Microbes are similarly involved with these other two important greenhouse gases. How this will play out in a warming world is uncertain. Our own activities, including attempts to limit effects of climate change, will certainly have a role. What we must certainly avoid are strong positive feedbacks that result in greater emissions as the world increasingly warms.

We’ll look at the microbes involved at global and local scales, ways in which they might respond in the future and approaches to reducing their contribution to warming. New Zealand is unusual in that methane and nitrous oxide, mostly from agriculture, make up about 55% of our national contribution to global warming.

Supper and a chat afterwards. All welcome.
