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.

Last year marked the hottest on record, shattering previous temperature benchmarks across both land and sea. The rapid escalation – seemingly at odds with the expected cooling after coming out of a La Niña cycle – has prompted scientists to question if climate change is accelerating beyond our models' predictions

Just eight minutes of anger can significantly impair blood vessel function and potentially increase the risk of a heart attack. A study has looked into the physiological mechanisms of how intense emotions can affect cardiovascular health.

GPS jamming continues to increase in European airspace, a concerning trend that has intensified since Russia's 2022 invasion of Ukraine. Now, attacks in Estonia have prompted one airline to completely abandon flights to the city of Tartu. We discuss the implications for civilian and military aviation and the potential need for alternative navigation technologies.

Birds do it, bees do it and so do many species of fly – it’s pollination. In fact, migrating flies play an even bigger role in pollination than we thought. These tiny travelers contribute to ecological diversity and resilience by transporting pollen over vast distances.

Plus: A newly discovered sensory organ in praying mantises, used specifically for tasting leaves; the possibility of carbon negative cement; and just how thick is the boundary between air and water?

Hosts Christie Taylor and Timothy Revell discuss with guests Madeline Cuff, Clare Wilson, Jeremy Hsu, and Michael Le Page. To read more about these stories, visit newscientist.com.

Did you miss out on the recent total eclipse? Don’t fear, we’ve got the solution. We bring you the constant solar eclipse.

Chelsea Whyte and Leah Crane have decided not to destroy the Sun this time. Instead, they just want to block it from view at all times. But it’s all in the name of good – so everyone gets to experience the same “primal fear” Leah did when she first saw an eclipse.

What starts with a modest-sized sunshade in low-Earth orbit creating 5 second eclipses, quickly turns into moving entire planets at the risk of all life on Earth. With the help of astronomer Bruce Macintosh from UC Santa Cruz, they also create the biggest piece of art ever made and call on the help of the world’s knitters.

Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from punching a hole in a planet to unifying the asteroid belt to destroying the sun – and subjects them to the laws of physics to see how they fare.

Your hosts are Leah Crane and Chelsea Whyte.

If you have a cosmic object you’d like to figure out how to destroy, email the team at deadplanets@newscientist.com. It may just feature in a later episode.
