As world leaders began to gather at Cop27 yesterday, speeches began on the main stage in Sharm el-Sheik. Presidents and prime ministers spoke of the need to rapidly reduce carbon emissions and the horrendous impacts of climate breakdown. But, if previous years are anything to go by – these words may not turn into concrete actions. Instead, indigenous and community groups are leading the charge on saving the planet. Madeleine Finlay speaks to Nina Lakhani about the need for climate justice, and hears from activist Nonhle Mbuthuma about her fight to protect South Africa’s Wild Coast.

On Sunday, world leaders, negotiators and industry representatives will begin to arrive in Sharm el-Sheik in Egypt for Cop27, the UN’s climate change conference. A UN report set the stage for talks last week, stating that there is “no credible pathway to 1.5C in place” and that progress on limiting global temperature rises has been “woefully inadequate”. 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’s climate and environment editor Adam Morton about what’s happened since Cop26, our current path to catastrophic heating and what’s likely to be on the agenda over the next two weeks.

A new trial is exploring if prescriptions of surfing, gardening and dance classes can reduce anxiety and depression in people aged 11 to 18. NHS mental health trusts in 10 parts of England will use a range of sports, arts and outdoor activities with 600 young people to see if it can stop conditions worsening while the sufferers are on waiting lists for care. This kind of support is known as ‘social prescribing’, allowing health professionals to refer patients to a range of community groups and organisations. But while social prescribing programmes are being rolled out around the world, a recent review has found scant evidence of their effectiveness. Madeleine Finlay speaks to Prof Susan Smith about the ideas behind social prescribing, its potential benefits for those with complex issues, and why more studies are urgently needed.
