Rerun: Removing Dams on Rivers to Ensure Climate Resilience for Salmon, with Regina Chichizola
The Benefits of Restoring Aquatic Ecosystems
For over a century, native salmon populations in California have been adversely impacted by human activities such as mining, dam building, and overfishing practices, often leading to the loss of critical habitat and decreased genetic diversity. With additional environmental stress from climate change, such as rising surface temperatures and changes in freshwater temperature and flow, salmon populations have been quickly declining. In addition, dams trap salmon into the warmest parts of the watershed, where they are more vulnerable to predators and have decreased breeding area necessary for their survival. Salmon are a...
Rerun: Recyclable Resin for Wind Turbines, with Ryan Clarke
The Benefits of Recycling Wind Turbines
While wind energy is renewable and non-polluting, the wind turbines themselves can create pollution problems. Now, scientists are creating wind turbines that can be made with less energy, but also create less waste because they can be recycled. This, of course, reduces impacts on the waste stream and provides a sustainable alternative to current wind turbines that are often extremely hard to recycle. Moreover, the new material requires less energy to create and mold into the desired output, subsequently reducing associated greenhouse gas emissions.

Rerun: Alleviating Urban Heat Traps, with Jeff Goodell
What Does Extreme Heat Do?
Since the pre-industrialized era, the global temperature has increased by about one degree Celsius. Although one degree may not seem significant, the consequences are increases in the intensity of heatwaves and drier conditions. In addition, in dense urban settings buildings trap and absorb this heat and cause even a higher area of heat relative to surrounding areas. The heat island effect is also exacerbated by the lack of greenery. With current fossil fuel emissions, increased heating of 1.5 degrees Celsius or more is predicted to happen globally within this decade. Among the most...
