On Sunday, world leaders, negotiators and industry representatives will begin to arrive in Sharm el-Sheik in Egypt for Cop27, the UN\u2019s climate change conference. A UN report set the stage for talks last week, stating that there is \u201cno credible pathway to 1.5C in place\u201d and that progress on limiting global temperature rises has been \u201cwoefully inadequate\u201d. So will governments take the opportunity to press ahead with their promises or could the conference live up to accusations of greenwashing? In the first of five special episodes covering Cop27, Madeleine Finlay hears from Guardian Australia\u2019s climate and environment editor Adam Morton about what\u2019s happened since Cop26, our current path to catastrophic heating and what\u2019s likely to be on the agenda over the next two weeks.
