Last year, the UN’s Intergovernmental Panel on Climate Change (IPCC) released its Sixth Assessment Report, featuring inputs from more than 700 experts from around the world. Over a third of the report’s co-authors were women, a higher percentage than ever before. According to the UNESCO Institute for Statistics, women account for less than 30% of all researchers globally. From career progression to publishing to salaries, there are sizable gaps between men and women in science – which is why the IPCC is making a concerted effort to tackle these inequities. In this episode, originally aired on the International Day of Women and Girls in Science in February 2021, we speak with IPCC vice-chair and acclaimed climate policy expert Ko Barrett about how science can become more equitable – and why equity is so crucial to the climate.
