Six months to Cop28: will the most vital summit yet make meaningful progress?
Every year, the world’s leaders gather for the UN climate change conference. At Cop28, they will be faced with two stark warnings from scientists: we are likely to breach 1.5C warming above pre-industrial levels in the next five years, and we are on course to reach 2.7C of warming by the end of the century. Progress has never been more critical and this year it lies in the hands of the United Arab Emirates, a country that has plans to expand its already extensive oil and gas productions. With six months to go, Madeleine Finlay talks to environment correspondent Fiona Harvey about Cop28’s hosts and president, why this year is particularly key, and how close we are getting to irreversible climate tipping points.

Japanese knotweed: why is it so damaging and can it be stopped?
Since it was introduced to the UK in 1850, Japanese knotweed has gone from novel ornamental plant to rampant invasive species. Madeleine Finlay speaks to journalist Samanth Subramanian about the huge costs associated with finding it on a property, and Dr Sophie Hocking explains what the plant, and our attempts to control it, might be doing to the environment..

What will we eat in a post-1.5C world?
We now know that global temperatures are likely to temporarily rise by more than 1.5C above pre-industrial levels in the next five years. Breaching this crucial threshold will give humanity an insight into what the next few decades could bring. It will undoubtedly have serious consequences in all aspects of our lives, including what we eat. In the second of our special series of episodes looking at what a future world might look like, science editor Ian Sample explores how our diets could change as the Earth heats up. Ian talks to Kew’s kitchen gardener Helena Dove about climate-resilient vegetables, visits Tiziana di Costanzo’s insect farm to try mealworms and crickets, and hears from Solar Food’s CEO, Pasi Vainikka, about making food from bacteria, electricity and air.

Menopause: could a new brain-based treatment cure hot flushes?
A first-of-its-kind non-hormonal drug to treat hot flushes has been approved in the US. Targeting connections in the brain that change during menopause, the drug, called fezolinetant, could provide relief for those who aren’t able to take hormonal replacement therapy. Madeleine Finlay speaks to endocrinologist and menopause specialist Prof Annice Mukherjee to find out what we know about the mechanism that causes hot flushes, how this new drug works, and what it might mean for those experiencing menopause in the future..

Is it the beginning of the end for scientific publishing?
More than 40 leading scientists have resigned en masse from the editorial board of a top science journal in protest at what they describe as the ‘greed’ of the publisher. Ian Sample speaks to correspondent Hannah Devlin about the remarkably lucrative business of scientific publishing, hears from Prof Chris Chambers about what was behind the recent mass resignation, and finds out why researchers are demanding change.
