The Tax on Cow Burps and Effective Climate Policy w/ Dr Kevin Trenberth

150 countries recently signed the Global Methane Pledge, promising the most effective course for reducing emissions and keepimg warming below 1.5°C. However, experts are calling this claim into question. This is particularly so in Aotearoa, whose largely agricultural methane emissions differ from that of other countries. 

Hanna spoke to Dr Kevin Trenberth, Distinguished Scholar at Colorado's National Centre for Atmospheric Research and Honorary Affiliate at the University of Auckland. They talked about why biogenic methane cannot be treated like fossil methane, nor methane like carbon dioxide, and whether current climate policy is up to scratch.
