This month the Royal Society of Chemistry released a shocking report on racial inequality at all stages of academia, from research funding to career progression. Black scientists in particular are unfairly disadvantaged when it comes to funding allocation. This is bad for them, bad for science, and bad for society. So how do we change things? Dr Diego Baptista from the Wellcome Trust, Professor Melanie Welham from the UKRI, and Dr Addy Adelaine, from the non-profit organisation Ladders4Action, join us to discuss the issue. Both of Earth’s poles were hit by heatwaves this week. The Arctic was 30 degrees above average for this time of year, and the Antarctic was an unprecedented 40 degrees above average. We are seeing more extreme temperatures everywhere on earth, but for both poles to experience such heatwaves at the same time is highly unusual. Ed Blockley of the Met Office’s Polar Climate Group explains what’s going on. One of the simplest ways to improve your local environment is to plant a hedge, which not only helps wildlife but can reduce flooding and pollution. But what kind of hedge should you plant? Scientists at the University of Reading and the Royal Horticultural Society are beginning a two year experiment to see which combinations of hedges bring the most benefits. Dr Tijana Blanusa tells us why planting hedges and generally greening our gardens is so important in the current climate. Presented by Gaia Vince Producer Cathy Edwards Assistant Producer Emily Bird
