greenhouse gas emissions

Climate scientists warn that emissions need to fall quickly. Those cuts will be even tougher with the Build Back Better legislation shelved for the foreseeable future.

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.

Nations are beginning pivotal talks to stop extreme climate change, but a new study shows even recent pledges to slow emissions aren't enough.

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.

Burning fossil fuels must decline almost immediately, a new study finds, for the planet to avoid more extreme floods, droughts and heat waves.

Scientists said the concentration of carbon dioxide, which contributes to climate change, is the highest in data going back 800,000 years, based on ice core records.

At least 21 people died in floods in Tennessee over the weekend. Such dangerous flash flooding is a hallmark of climate change.

Allison Crimmins, who heads the National Climate Assessment, says the U.N.'s landmark report confirms the need for "significant, sustained action" to reduce emissions.

Cutting carbon emissions to zero in the next 30 years would save about 74 million lives this century, a new analysis estimates.
