Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level and ocean heat content all reached record highs in 2023, according to the 34th annual State of the Climate reportoffsite link.

The Air Quality Stripes which were created by the University of Leeds, the University of Edinburgh, North Carolina State University, and the UK Met Office, starkly contrast the significant improvements in air quality across much of Europe with the alarming deterioration in parts of Africa and Central Asia.

A new study reveals how ocean biology and marine pollution can end up on Antarctica’s shoreline.

Scientists have found microplastics in brain tissue.

Excess carbon dioxide emitted by human activities—such as fossil fuel burning, land-use changes, and deforestation—is known as anthropogenic carbon dioxide.

Currently, industrial processes in the U.S. account for approximately a third of the country’s carbon dioxide emissions – even more than the annual emissions from passenger vehicles, trucks, and airplanes combined. Decarbonizing this sector is a challenging but vital step in mitigating impacts on our future climate.

Tanager-1, the Carbon Mapper Coalition’s first satellite, which carries a state-of-the-art, NASA-designed greenhouse-gas-tracking instrument, is in Earth orbit after lifting off aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Space Force Base in California at 11:56 a.m. PDT Friday, Aug. 16.

Unprecedented wildfires in Canada last year were three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the first annual review of its kind.

Scientists previously thought warming temperatures caused by climate change and increased nutrient levels due to pollution might offset each other’s impact on aquatic life.

In 2011, Philadelphia’s city-owned water utility drew national attention when it began Green City, Clean Waters, a 25-year program to manage an increasing volume of stormwater by using mostly “green infrastructure,” such as rain gardens and porous pavements, which allows rain to soak into the ground rather than becoming runoff that pollutes rivers and creeks.
