Source: PBS News Hour The U.S. Environmental Protection Agency is expected to repeal rules that limit planet-warming greenhouse gas emissions from power plants fueled by coal and natural gas, an action that Administrator Lee Zeldin has said would remove billions of dollars in costs for the industry and help "unleash" American energy. At a speech to the United Nations last year, President Donald T…

Philadelphia recently faced an intense summer defined by severe storms, widespread flooding, soaring Temperature anomalies, and choking Canadian wildfire smoke. […]

On the heels of the hottest summer on record and a United Nations report warning that global temperatures are likely to push climate risks to “increasingly dangerous heights,” the Trump administration overturned most of a Biden-era rule limiting climate pollution from power plants, the second-largest source of greenhouse gas emissions.  The Environmental Protection Agency announced […]

On September 8, 2026, New York City released approximately 170,000 pages of records concerning air quality, health risks and the government response following the collapse of the World Trade Center on September 11, 2001.

The US Environmental Protection Agency today finalized the repeal of the Clean Air Act 111(d) standards, which regulated greenhouse gas emissions from the power sector. This follows the administration’s earlier rescission of the endangerment finding, the key legal determination that allowed the federal government to regulate greenhouse gases. This statement may be attributed to Carbon Capture Coa…

The Trump administration is eliminating limits on climate-warming pollution from the nation's fossil fuel power plants. Environmental groups say this will impact the climate and public health.

The reversal of a Biden-era cap on emissions from the plants could have devastating effects in efforts to stop climate change

A World War I submarine wreck off Denmark is leaking TNT into the surrounding water, seabed, and marine life more than a century after it sank. Scientists warn that thousands of similar wrecks could pose growing environmental risks as they continue to corrode.

Wyvern’s five-satellite Dragonette constellation delivers high-resolution hyperspectral imagery. The data enables detection and differentiation of subtle biophysical and geochemical changes, including detailed analysis of vegetation health, soil composition, water quality, and a variety of other environmental conditions that impact ecosystems and human well-being. Each satellite carries a visible…
