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.

Almost all of China's medium and large cities are susceptible to floods. Some experts are promoting a solution called sponge cities — urban landscapes that are softer and meant to absorb more water.

The legendary anthropologist talks about the roots of her advocacy and why she still has hope for protecting the planet.

Melissa Hoffer is Massachusetts’ first-ever Climate Chief, appointed in April by Governor Maura Healey to lead the newly created Office of Climate Innovation and Resilience. Massachusetts is the first state in the nation to establish such a position at the cabinet level. She previously has held high-level posts in the General Counsel's Office of the Environmental Protection Agency.

Katharine Hayhoe is perhaps the nation’s leading voice in communicating about climate solutions across often-polarized political and cultural lines. An atmospheric scientist whose research focuses on understanding the impacts of climate change on people and the planet, she recently authored Saving Us: A Climate Scientist’s Case for Hope and Healing. She is a Distinguished Professor at Texas Tech University and serves as Chief Scientist for The Nature Conservancy.

As new research shows that climate change is causing foliage colors to peak two weeks later than in 1950, Acadia National Park is urging visitors to plan accordingly.

Funding that rolls out this fall expands on the Biden Administration's Justice40 initiative.

Gov. Maura Healey spoke about the initiatives at the Clinton Global Initiative meeting in New York City.

Earth Commission, the prestigious international group of scientists, recently published a study that is receiving a great deal of attention. The study in Nature Journal indicates that we have now breached most of the Earth system boundaries that include climate, biodiversity, fresh water, soil and air. Millions of people have already been displaced, worldwide health is threatened, extinctions are accelerating, ecosystems are being destroyed. The authors emphasize two things: (1) that urgent action is required to save the planet; and (2) action must include justice for the masses who are suffering the results of global destruction.
