A new NASA study reveals significant global declines in microscopic ocean plant-life, or phytoplankton, which form the base of the marine food chain. This research is the first to analyze long-term phytoplankton community trends using NASA satellite data.

Diatoms, the largest type of phytoplankton, decreased over 1% annually from 1998 to 2012, particularly in the North Pacific, North Indian, and Equatorial Indian oceans. This reduction could impact the amount of atmospheric carbon dioxide absorbed and stored in the deep ocean. Dr. Cecile Rousseaux is featured.

This B Corp Global Climate Summit session, part of the Day 2 Africa Regional Session, explores the circular economy. This model aims to eliminate waste, boost resource productivity, and redefine how we design and reuse resources. With food waste alone contributing 3.3 billion tonnes of CO2 annually, and the linear economy's flaws exposed by COVID-19, the circular economy offers a new paradigm with an estimated $4.5 trillion annual economic potential by 2030.

The session will delve into applying circular principles to food waste management, how businesses adopt circularity for resilience, and real-world company case studies. It will also discuss the circular economy's potential for a green post-pandemic recovery. Speakers include Grace Wachori, Martha Nalweyiso, Matt Homewood, Daniel Chege, and Rita Atuti.

"NASA Space Recordings of Earth" reveals our universe is not silent. Although space is a vacuum, sound exists as electromagnetic vibrations.

Specially designed instruments on board the Voyager and other probes captured these vibrations. These recordings fall within the range of human hearing (20-20,000 cycles per second).

Forests are vital for global economies and millions of livelihoods, creating jobs, income, and supporting communities. They contribute trillions to the global economy by providing essential ecosystem services like water, climate, and soil, alongside ecotourism, energy, and raw materials.

Join us in celebrating the International Day of Forests on March 21!

Oxford data scientist Hannah Ritchie debunks the overpopulation myth, a concern prominent since the 1960s. While global population is still growing, its rate has significantly slowed, contrary to earlier exponential growth assumptions. Ritchie, a lead researcher at Our World in Data and Oxford, specializes in environmental sustainability.

On April 8, 2024, CLG Europe’s Materials and Products Taskforce hosted a WCEF Side Event webinar: "How the new EU institutions can kickstart the Circular Economy." Ahead of European elections, experts discussed the circular economy's political role. A recent ESABCC report highlights minimal EU progress in circular material use, increasing from 10.8% (2010) to 11.7% (2021).

To meet the EU's 2030 goal of doubling this rate, a tenfold increase in current annual progress requires more recycling and less material demand. The Taskforce, established in 2021 to drive policy, will release a report later this year. It will set the EU's circular economy policy agenda for the next five years, recommending actions to accelerate the shift to climate-neutral materials.

Society faces an existential crisis: 84% fossil fuel energy drives catastrophic climate change and pollution, causing one in six deaths. Extreme light applied to nuclear energy could offer a solution, activating materials like thorium or boron for abundant, waste-free, and radiation-free power.

This innovative path draws on the work of Nobel laureate Gérard Albert Mourou. The French physicist co-invented a laser amplification technique, earning him the 2018 Nobel Prize in Physics. His invention also enabled refractive femtosecond eye surgery, used on over a million patients annually. This talk was given at a TEDx event. Learn more at ted.com/tedx.

Alessandra Ivul, born in 1981, co-founded the artistic collective Panem Et Circenses in 2012 with Ludovico Pensato. She previously worked in public art, using food culture as a primary tool for inquiry and expression. More recently, her research has shifted to ecosystem change, focusing on new approaches and visions.

Their latest project is an organic and regenerative farm in the Bolognese Apennines, where they live and cultivate near the forest. This talk was given at a TEDx event, independently organized by a local community. Learn more at https://www.ted.com/tedx.

Guido Zichittella, 27, a Sicilian, earned his Bachelor of Science in Chemical Engineering from Politecnico di Milano in 2013. He completed his Master of Science in Chemical and Bioengineering at ETH Zurich in 2015, receiving an award for the best thesis from the Swiss Process and Chemical Engineers Association. He has received numerous academic honors, including the Chemistry Travel Award and the prestigious "ETH Grant."

Currently, Zichittella is a PhD candidate at ETH Zurich in Professor Javier Pérez-Ramírez's Advanced Catalysis Engineering group. In 2019, Forbes recognized him among Europe's 30 most influential scientists under 30.

David Wallace-Wells observes that few Silicon Valley titans are addressing climate change, despite the opportunity to leave a significant legacy. He points to Bill Gates-funded negative emissions technology, which could enable current industrial activity without global warming.

This technology would cost $3 trillion annually to operate worldwide. While substantial, this figure is less than the $5 trillion spent each year on global fossil fuel subsidies.

Wallace-Wells, author of [The Uninhabitable Earth: Life After Warming](https://amzn.to/2Of5N3y), shared these insights.
