Beneficial out in the open ocean, the seaweed has been coming shore in much larger than normal amounts over the past decade.

On Friday, April 7, 2023, NASA launched the Tropospheric Emissions: Monitoring of Pollution (EVI-1) (TEMPO) satellite mission from the Kennedy Space Center. TEMPO will provide high resolution air quality data on an hourly basis across North America.

The National Integrated Heat Health Information System (NIHHIS) will hold its second annual meeting April 25–27, 2023. Registration is now open.

Registration is open for the Climate Variability and Predictability Program webinar series on Decadal Climate Variability and Predictability.

Since the start of the Industrial Revolution in 1750, the ocean has absorbed 20–30 percent of the new carbon dioxide emissions. That has mitigated rising atmospheric temperatures but increased ocean acidification. A new data set spanning 1750–2100 predicts future ocean chemistry.

With a 62% chance that El Niño conditions will develop by May–July, NOAA is issuing an El Niño Watch.

NOAA's network of moored buoys in the tropical Pacific is getting an upgrade that will help scientists better understand and predict El Niño and La Nina.

In 2022, the global surface average for carbon dioxide rose by 2.13 parts per million, roughly the same rate observed during the last decade. Atmospheric methane, less abundant but more potent, rose by 14.0 parts per billion, the fourth-largest annual increase recorded since NOAA’s systematic measurements began in 1983.

Scientists make informed predictions about climate and weather with operational models. Scientists test theories and improve forecasts with experimental models, including two new models: SHiELD and SPEAR.

This summer, NOAA and citizen scientists will map the hottest parts of 18 communities in 14 states across the country and in one international city. Identifying these urban heat islands helps local decision-makers take actions to reduce the health impacts of extreme heat, which often target the most vulnerable.
