Solar Storms and Climate History

A Week Of Climate Protests, Meetings, Pledges, And Action

Climate Week NYC is wrapping up, where hundreds of events took place across the city (including one from Science Friday), all with the goal of encouraging conversation and action around our climate crisis.

The weeklong event takes place alongside the UN General Assembly meeting, where world leaders discussed climate change, alongside other topics, including the war in Ukraine and universal health coverage.

While President Biden emphasized the importance of reducing the use of fossil fuels to combat climate change, there was a notable absence of leaders from the world’s biggest polluters, including Biden and president Xi Jinping of China, from the meeting’s Climate Ambition Summit. UN Secretary-General António Guterres said that in order to participate, governments need to come with “credible, serious and new climate action.”

Large demonstrations also took place across the city, pressuring leaders and companies to take bigger action to end gas, oil, and coal use.

Swapna Krishna, a journalist based in Philadelphia, talks with Ira about these stories and more, including a new climate jobs program from the White House, a lawsuit from California against the five big oil companies, new battery recycling rules from the EU, and data from the Parker Solar Probe’s recent flight through a sun explosion.

Can Earth’s Past Climate Help Us Understand Today’s Crisis?

A combination of factors led to Earth’s climate being able to support life. And changes in the climate some 6,000 years ago created the conditions for human civilization to flourish. It’s a delicate balance on the verge of collapse, due to our reliance on burning fossil fuels.

Ira talks with paleoclimatologist Dr. Michael Mann about his forthcoming book Our Fragile Moment: How Lessons from Earth’s Past Can Help Us Survive the Climate Crisis, about the importance of understanding our planet’s climate history, and strategies to get policymakers to take action before it’s too late to reverse some of the worst consequences of climate change.

Mann is a professor of earth and environmental science and director of the Penn Center for Science, Sustainability and the Media at the University of Pennsylvania, based in Philadelphia, Pennsylvania.

The Climate Movement Should Be Funnier

How do you know that climate change is funny? Even the Antarctic ice sheets are cracking up.

The climate crisis is no joke, but that doesn’t mean we can’t laugh about it. Research suggests that comedy is a powerful way to connect people and get them to empathize with a cause—and the climate crisis is a pretty big one.

So what does science say about the power of a good laugh? And how does that fit into the climate movement?

Ira talks with Esteban Gast, comedian in residence at the clean energy non-profit Generation 180, and Dr. Caty Borum, executive director of the Center for Media & Social Impact at American University.
