Climate Program Office and community scientists to map urban heat inequities in 11 states
Department:April 20, 2021Source:Extreme heat kills more Americans than any other weather event, but not everyone’s risk is the same. Within the same city, some neighborhoods can be up to 20°F hotter than others. In the summer of 2021, community-led campaigns will map the hottest parts of cities in 11 states: Albuquerque, New Mexico; Atlanta; New York City; Charleston, South Carolina; Kansas City, Missouri; Raleigh and Durham, North Carolina; San Diego; San Francisco; and parts of New Jersey, Indiana, Massachusetts, and Virginia.
Drought task force shows progress in advancing drought monitoring and prediction in new special collection
Department:April 20, 2021Source:In a special collection of the American Meteorological Society, 13 papers produced by researchers from the third NOAA Climate Program Office’s Modeling, Analysis, Predictions, and Projections (MAPP) program Drought Task Force (DTF3) describe research advances leading to improved monitoring, prediction, and understanding of past droughts.
Giant Australian bushfire injected 1 million tons of smoke into the atmosphere
Department:April 20, 2021Source:New research on the massive Australian bushfires in 2019 and 2020 shows that almost 1 million metric tons of smoke rose into the stratosphere, causing it to warm by about 1 degree Celsius for six months, and likely contributed to the large and persistent ozone hole that formed over Antarctica during the Southern Hemisphere’s spring.
Five ways NOAA scientists are answering big questions about climate change
Department:April 20, 2021Source:Tracking greenhouse gas levels in the atmosphere, understanding ocean warming, exploring the link between climate change and hurricanes, tracking warming in the Great Lakes, and working towards climate resilience are just five examples of the many ways NOAA scientists are answering question about climate change and its potential impacts on human societies.
‘Average’ Atlantic hurricane season to reflect more storms
Department:April 13, 2021Source:As NOAA adopts 1991–2020 as the new 30-year period of record, “average” hurricane activity in the Atlantic Ocean will increase. Average activity for the new period of record means 14 named storms, 7 hurricanes, and 3 major hurricanes.
Tackling the challenges of a drier, hotter, more fire-prone future
Department:April 13, 2021Source:With wildfires in the western United States burning nearly 3.56 million hectares (8.8 million acres) in 2020, or about 75% more area than expected in an average year, it’s important to know how droughts, wildfires, and heat waves interact. How do they shape each other’s likelihoods, magnitudes, and impacts?
Despite pandemic shutdowns, carbon dioxide and methane surged in 2020
Department:April 7, 2021Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus...
Recording now available: Webinar about future flooding in the Pacific Northwest
Department:April 6, 2021Source:Researchers with the Pacific Northwest Climate Impacts Research Consortium (CIRC) have projected widespread increases in flood magnitude throughout the Columbia River Basin in a warmer climate. By 2050, much of the Pacific Northwest could experience increased flood magnitudes. The webinar associated with this study, recorded March 5, 2021, is now available online.
A practitioner's guide to climate model scenarios for the Great Lakes
Department:April 6, 2021Source:On March 15, 2021, the Great Lakes Integrated Sciences and Assessments (GLISA), published new guidance, “A Practitioner’s Guide to Climate Model Scenarios.” The guide summarizes differences between the scenarios for the Great Lakes region to show how the choice of model scenario affects future temperature and precipitation projections.
Who is vulnerable and who is resilient to coastal flooding? Lessons from Hurricane Sandy in New York City
Department:April 6, 2021Source:Severe storms might seem like great equalizers, but coastal flooding doesn’t affect everyone the same way. A new study in Climatic Change highlights the factors that make some people in the storm’s path more vulnerable.
