An international study finds methane emissions from oil and gas activities over 2010–2019 were 70 percent higher than previously estimated by the US Environmental Protection Agency. But the study also finds the rate of methane emissions fell slightly over that period.
Green infrastructure mimics natural processes and can mitigate impacts of urban development and climate change, but uncertainties remain about its effectiveness. A new open-source tool may help decision makers.
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.
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.
In addition to higher ocean temperatures, corals face threats from stony coral tissue loss disease stresses. Using a crowdsourcing approach, scientists have characterized the global bacteria patterns associated with the disease.
