Chemical products that contain compounds refined from petroleum, like household cleaners, pesticides, paints and perfumes, now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study by researchers from CU Boulder and other institutions.

Carbon emissions from the Brazilian Amazon are increasingly dominated by forest fires during extreme droughts rather than by emissions from fires directly associated with the deforestation process, according to a study in Nature Communications.

The Paris Agreement has aspirational goals of limiting temperature rise that won’t be met by current commitments. That difference could make the world another degree warmer and considerably more prone to extreme weather.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard Aqua provided a visible-light image of the tropical depression on Feb. 15, 12:50 a.m. EST (0550 UTC). 

Dust that blew into the North Pacific Ocean could help explain why the Earth’s climate cooled 2.7 million years ago, according to a new study published in the journal Science Advances.

Hurricanes spawn most of the largest storm surges in the northeastern U.S., right? Wrong, according to a study by Rutgers University–New Brunswick scientists.

The added weight, electricity demand and aerodynamic drag of the sensors and computers used in autonomous vehicles are significant contributors to their lifetime energy use and greenhouse gas emissions, according to a new study.

Last year was a record-breaking one for Operation IceBridge, NASA’s aerial survey of the state of polar ice. For the first time in its nine-year history, the mission, which aims to close the gap between two NASA satellite campaigns that study changes in the height of polar ice, carried out seven field campaigns in the Arctic and Antarctic in a single year.

Infrared light provides valuable temperature data to forecasters and cloud top temperatures give clues about highest, coldest, strongest storms within a hurricane.

How might climate change affect the acidification of the world’s oceans or air quality in China and India in the coming decades, and what climate policies could be effective in minimizing such impacts?
