Beyond Carbon: How Fixing the Ozone Layer Contributes to Climate Change
The greenhouse effect is not all about carbon dioxide. Several other substances, such as water vapor and methane, also play a key part in trapping radiation. Recently, a family of relatively obscure chemicals called hydrofluorocarbons, or HFCs, has entered the spotlight due to its role in global warming. HFCs are highly potent greenhouse warmers –…

In its report, the EPA found that the Gowanus Canal “has…

Hydraulic Fracturing – Potential for Contamination of Drinking Water Sources
Hydraulic fracturing is a technique used by the oil and gas industry to facilitate natural gas recovery in underground low permeability coalbed methane wells. This operation improves the extraction efficiency of methane by creating fissions or fractures in underground rock formations, generally 5,000 – 20,000 feet below the ground surface. Highly pressurized hydraulic fracturing fluids,…

Recently, the Obama administration has been getting harsh reviews from some environmentalists for its decision to open several new areas of the US to offshore drilling. Putting this admittedly odd decision aside though, the Thursday April 1 (April Fool’s Day) decision to roll out tough new water quality standards that could severely limit some of the most destructive…

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana.
