Hansen's El Niño Warning

In this episode we examine James Hansen’s analysis of a developing El Niño against the backdrop of a rapidly warming planet. We discuss Hansen’s warning that global warming may be accelerating as Earth absorbs more energy, and that an El Niño occurring on top of this elevated heat could help drive exceptionally high global temperatures in the years ahead.

The panel explores how warmer oceans and air can intensify climate extremes, including heat waves, heavy rainfall and flooding in some regions, drought and wildfire in others, and greater stress on water supplies. A major focus is food security: the speakers connect drought, heat, changing agricultural conditions, and lower crop production to risks for farmers, food prices, economies, and communities worldwide.

The conversation also considers the wider social consequences of climate disruption, including public-health risks from extreme heat, pressure on rivers and water systems, geopolitical instability, and the difficulty of adapting as climate conditions shift. The speakers emphasize the need for stronger adaptation measures while arguing that rapid reductions in fossil-fuel emissions remain essential to limiting the worsening impacts of climate change.
