The sustainable future we are collectively building comes with significant environmental costs, primarily felt by the global south. The mining and processing of rare earth metals, nickel, cobalt, copper, and many other critical materials, essential for electrification and renewable technologies, often result in considerable ecological damage.

These activities can lead to deforestation, contamination of water sources, soil erosion, and the emission of harmful gases. Consequently, the health and safety of workers and local residents are compromised along with the environment. All of this stands in stark contrast to the overall goals of the green revolution, but currently represents an unavoidable aspect of progress.

This talk explores how the mining and extraction of these materials, while essential for driving forward the clean energy revolution, often contradicts the principles of environmental stewardship. The lecture particularly focuses on the impact in the global south, where much of the world's mining and refining activities take place, often with less stringent environmental regulations and oversight. This raises critical questions about the true cost of our transition to renewable energy and electric mobility.

In response to these challenges, Dr. Tomas Villalón shares Phoenix Tailings’ transformative approach to mining and material processing. Our innovative strategies aim to revolutionize the industry by extracting rare earth metals and other crucial materials sustainably. He discusses their cutting-edge techniques for minimizing ecological impact through rethinking the approach to material refining and the remediation of toxic waste. By turning a historically pollutive process into a more environmentally responsible one and cleaning up the toxic byproducts of mining operations, Phoenix Tailings is not only contributing to the cleaner production of electrification materials but also paving the way for a more equitable and truly sustainable future.

As climate change stories become more frequent

Heavy rains, flooding and destructive winds and tornadoes snarled traffic and knocked out power up and down the East Coast.

The state is experiencing more "tropical nights"

Gov. Maura Healey plans to hire a new chief coastal resilience officer to lead the effort.

The major ocean currents strongly influence regional climate stability. Today’s rapidly warming oceans will ultimately alter major currents such as the AMOC, with huge consequences for global climate. In order to predict when and where these climate shifts will occur, oceanographers gather data over a long period of time and compare that data with historical variations in ocean temperature and currents. Hali Kilbourne’s focus on 2000 years of the relationship between oceans and climate provides important data for accurate climate models.
In this discussion Dr. Kilbourne describes how scientists collect and analyze the data, and what oceanographers can predict regarding sea level changes, stability of major currents and the coming impact on global climate.

Melissa Hoffer recommends limiting the amount of "short hop" flights and decarbonizing new school construction, among other actions.

This summer was the hottest since 1880, according to NASA. But a new wind power partnership and an $11 million grant for Boston's tree canopy is taking root.

Julia Bae has been interested in environmental justice since she first learned about climate change in fifth grade.

Clouds are an essential component of the climate. In normal circumstances, they stabilize Earth’s temperature, both by preserving the planet’s heat like a blanket and blocking excess solar radiation. But with prolonged accumulation of atmospheric CO2, the planet overheats, leading to dramatic effects, including massive wildfires –which release particles called “biomass aerosols.” Those particles seed clouds that affect the climate. In this program, Dr. Cziczo explains how these clouds form and why the excess of biomass particles concern climate scientists.
