Katharine Hayhoe – Climate Change: What’s New?
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.
