Summary: Multiple U.S. coastal regions may see rapid increases in the number of high-tide flooding days in the mid-2030s, according to a new study. The combined effects of sea-level rise and natural fluctuations in tidal range are anticipated to cause tipping points in the frequency of high-tide flooding. These tipping points can produce acute impacts in underserved communities not prepared for the consequences.
The Southern Hemisphere’s stratosphere is cleaner than the Northern Hemisphere’s. A NOAA-NASA airborne mission that measured very small particles and trace gases in the lower stratosphere indicated that the cause of the relatively polluted Northern Hemisphere stratosphere is aircraft emissions.
The U.S. Climate Resilience Toolkit now includes a Southeast Region section. The section features narratives, tools, and case studies on the impacts of climate change across the Southeast, and information on how people can build resilience to climate change
A new study finds that raising modeled mountains reduces modeled rainfall biases. By underestimating the height of mountain ranges, climate models have shown biases in their representation of the Intertropical Convergence Zone (ITCZ), a tropical rainband that delivers significant precipitation.
So you think you know what’s in the ocean? Even with decades of scientific research, more than 80 percent of the ocean remains unmapped, unobserved, and unexplored. That’s a lot considering more than 70 percent of the globe is covered by the ocean. NOAA is using Argo floats, gliders, drifters, and moored buoys to better understand the ocean depth
The sudden, sustained rise in atmospheric methane since 2007 has posed one of the most significant, pressing questions in climate research: Where is it coming from? By analyzing stable carbon isotope ratios, a research team identified microbial sources.
To address worsening drought in the Northern Plains, the National Integrated Drought Information System is co-hosting a webinar series this summer specifically for the Tribal Nations in the Northern Plains.
Human health risks, stronger cyclones, coral reef death, and coastal flooding are among the major challenges detailed in a new report on climate change in American Samoa published June 8, 2021. The report highlights the fact that American Samoa counts among the locations likely to see early impacts of climate change.
The NOAA Blue Carbon Inventory (BCI) Project—an initiative led by the NOAA Climate Program Office (CPO) in partnership with the U.S. Department of State and the NOAA Marine Protected Areas (MPA) Center—is among the first Ocean Decade actions endorsed and announced this week by the United Nations Intergovernmental Oceanographic Commission of UNESCO (IOC).
On June 8, 2021, the National Integrated Drought Information System (NIDIS) released a strategy for the National Coordinated Soil Moisture Monitoring Network (NCSMMN). It is a multi-institutional effort to plan for and support nationally coordinated soil moisture monitoring, data assimilation, and product development.
