greenhouse gases

Some doctors are promoting propellant-free inhalers over puff inhalers that emit greenhouse gases. Climate change can exacerbate respiratory ills because of more fires, air pollution and allergens.

Scientists took a dozen research flights over major U.S. oil and gas fields to sample flare emissions. They found more methane than was supposed to be there.

The Earth has already warmed more than 1 degree Celsius. New research suggests that above 1.5 degrees, massive ice melt, ocean current disruptions and coral die-offs are likely.

A 30-year, nationwide study of ecological changes — including the effects of climate warming — has been releasing a powerful greenhouse gas, and critics want it to stop.

Americans use nearly four times the energy researchers say is needed to live a happy, healthy and prosperous life.

U.S. Secretary of Agriculture Tom Vilsack announced funding for pilot projects geared toward curbing greenhouse gas emissions in agriculture.

The spike was attributed to a slew of causes, including behavior changes after COVID-19 vaccines became widely available, but environmental advocates say it's worrisome.

A group of scientists used chemistry to convert the powerful greenhouse gas methane into safer chemicals that serve as the base for some plastics.

Carbon dioxide emissions are rebounding after a dip in 2020, and researchers say that at the current rate, Earth's "carbon budget" will be exhausted in roughly 11 years.

The U.N. meteorological agency says despite a decrease in emissions due to reduced economic activity during COVID-19, carbon dioxide and other warming gases continued to accumulate in the atmosphere.
