How do we understand the stakes of climate change, and communicate them? As we’re facing the consequences of climate change and our historical inaction as a species, how do we come to terms with the reality and uncertainty of our situation?

In H is for Hope: Climate Change from A to Z, Journalist and Pulitzer Prize-winning author Elizabeth Kolbert breaks things down for us, alphabetically. She dissects the narratives around climate change, from sobering facts about our warming planet, to innovations to fuel our optimism.

In this episode, Kolbert reminds us how dangerous our current situation is, and what we are missing in this fight – including gaps in our understanding of how fast the climate is changing. Plus, the role of narratives in shaping how we decide to act.

How much faith should we be putting in artificial intelligence? As large language models and generative AI have become increasingly powerful in recent years, their makers are pushing the narrative that AI is a solution to many of the world’s problems.

But Meredith Broussard says we’re not there yet, if we even get there at all. Broussard is the author of More than a Glitch: Confronting Race, Gender, and Ability Bias in Tech. She coined the term “technochauvinism,” which speaks to a pro-technology bias humans often have, where we believe technological solutions are superior to anything else.

In this episode, she tells New Scientist’s Sophie Bushwick that our trust in AI systems could have devastating consequences.

From discriminatory mortgage-approval algorithms, to the racial biases of facial recognition technology, to the misinformation that appears in chatbots like ChatGPT, Broussard explains why there’s no such thing as trustworthy AI. And she discusses the need for greater education about AI, to help us separate reality from marketing.

Half of the human population undergoes the menstrual cycle for a significant proportion of their lifetimes, yet periods remain a taboo topic in public and private life. And that makes it harder both to prioritise necessary scientific research into conditions like endometriosis and for people to understand the basics of how their bodies work.

Blood: The Science, Medicine, and Mythology of Menstruation is gynaecologist Jen Gunter’s latest book. In this practical guide, she dispels social, historical and medical myths about menstruation and offers answers to your biggest period-related questions – including why we menstruate in the first place, when a missed period is a health concern and “how heavy is too heavy?”

In this episode, Christie Taylor speaks to Gunter about how humans are part of an exclusive club of menstruators in the animal kingdom, the persisting social stigma around menstruation and menopause, and why these processes remain under-researched in science despite their vast importance. Plus, a call from Gunter to take seriously the very individual and sometimes painful experiences people may have with their periods, while also creating more access to menstrual care.
