Human emissions of greenhouse gases now overwhelm the influence of natural drivers in altering Earth's climate. How will our energy choices and resulting emissions affect temperature and precipitation, extreme events, sea-level rise and more over this century and beyond? What are the implications for meeting the targets of the Paris climate agreement and avoiding dangerous change? And what about the potential for surprise, as we push the climate system harder and faster than any other time in human history? Join Katharine Hayhoe as she highlights key results and new science from the U.S.’s Fourth National Climate Assessment and lays out how climate change is affecting regions and sectors across the country. With climate change being one of the most hotly debated scientific issues of today, Hayhoe will also discuss the key role our values play in shaping our attitudes and actions on this crucial topic.

Join astrophysicist Paul Sutter on a virtual tour of the solar system from the safety of your own home, exploring each of the planets in our cosmic neighborhood. This event is meant for the whole family and focuses on middle and high school state science standards. Sutter will also point out constellations you can see from your own backyard. Bring your curious questions because, after the tour, Sutter will stick around for an expert Q&A and trivia game.

In this webinar, Laura Kahn will provide a comprehensive overview of COVID-19 from three different perspectives: issues around emerging diseases spread from animals to humans; our country’s public health response during the outbreak; and the household-level response that everyone should undertake to respond to the pandemic.

Nothing is more treasured — and mysterious — than the bond between mother and child. After a mother gives birth, her brain and body change in ways that enable her to care for the new life. Bianca Jones Marlin examines the brain dynamics behind these changes, some of which are ‘remembered’ in the genes and passed down for generations. In her talk, she will challenge the age-old concept of ‘nature vs. nurture’ and show how a bridge between learned and innate animal behaviors is built. Audience members will also have an opportunity to participate using their senses to explore the real-time effects of neurochemicals in social learning.

Behind the Curve provides a peek into the world of Flat Earthers. In the film, proponents share their reasoning and discuss their experimental approaches to proving their world view. Scientists and professional science communicators, including astronaut Scott Kelly, give their take on the flat Earth conspiracy and discuss the current scientific views on conspiracies and the possible consequences of a lack of critical thinking in society.

At first glance, the Sleeping Beauty problem appears to be a simple question about probability. But since being proposed 19 years ago by philosopher Adam Elga, the problem has incited passionate debate in the philosophy community. In this talk, Peter Winkler will describe the famous thought problem about a dozy princess being awoken once or twice depending on the toss of a coin.
