Bleached coral reefs

Marine heatwaves becoming more intense, more frequent

Feb. 3, 2021

When thick, the surface layer of an ocean acts as a buffer to extreme marine heating—but a new study from CU Boulder shows this “mixed layer†is becoming shallower each year.

Impacts of COVID-19 emissions reductions remain murky in the oceans

Dec. 10, 2020

While greenhouse gas emissions dropped significantly in the first half of 2020, new research finds ocean acidification remains unchanged—yet the world's oceans can respond quickly in other ways to reduced emissions.

Niwot Ridge

Dec. 8, 2020

Niwot Ridge in the Rocky Mountains is slowly recovering from increased acidity caused by vehicle emissions in babyÖ±²¥app’s Front Range, suggesting that alpine regions across the Mountain West may be recovering. This is good news for the wildlife and wildflowers of Rocky Mountain National Park and for water sources that supply the Front Range and the Mountain West.

United Nations Framework Convention on Climate Change COP25

Worst-case emissions projections are already off track

Nov. 30, 2020

New research reveals that emissions are not growing as fast as the UN’s Intergovernmental Panel on Climate Change's assessments have indicated—and that the IPCC is not using the most up-to-date climate scenarios in its planning and policy recommendations.
