What Is Driving the Earth’s Warming? How Accurate Are the Climate Science Community’s Climate Models? What Are the Predictions for Climate Change in the 21st Century?
Weather is the prototypical complex system. Edward Lorenz, one of the pioneers of chaos theory, was a meteorologist. So why is climate change so controversial?
In this episode of Hidden Forces, host Demetri Kofinas speaks with NASA’s Chief Climate Scientist and Head of the Goddard Institute for Space Studies, Gavin Schmidt. The two cut through the controversy surrounding climate change and dive right into the heart of climate science. They parse through the data, explore the climate models, and consider the impact that further warming could have on humanity in the decades to come.
What is driving the warming of our planet? What is causing the acidification of the oceans? What is shrinking the ice sheets? What is causing the rise in sea levels, the decrease in snow cover, and the melting glaciers? Is there a causal connection between human activity and the prolonged droughts, intense heat waves, and raging wildfires we have seen in recent years? What are the feedback mechanisms of climate change? How do we measure the impact of losing reflective layers of ice, exposing permafrost, or releasing vapor into the atmosphere? What does the cooling of the upper atmosphere tell us about the cause of global warming? Could changes in solar activity, sunspots and cosmic rays, and their effects on clouds be to blame for climate change? How will humanity respond to more extreme weather events – hurricanes, droughts, floods, and forest fires – as our populations grow and the density of our coastal regions increases? And is there anything we can do, to prepare?
