Two NOAA hurricane experts explain why it’s still so hard to say whether global warming to date has affected the number or intensity of Atlantic hurricanes.

Summary: VELMA is a tool designed to model effective decisions for a wide array of environmental issues. It is a spatially explicit ecohydrological watershed model that planners can use to visualize the effects of their decisions.

The Argo program started in 1998 when scientists proposed a global array of autonomous floats to take temperature and salinity measurements of the world’s ocean. The program has won an award “for innovation in large-scale autonomous observations in oceanography with global impacts in marine and climate science and technology.”

The National Integrated Heat Health Information System (NIHHIS) Interagency Communications Group will host a heat season awareness social media campaign during the week of May 16, 2022. Themes will cover heat-related illness, heat vulnerability, outdoor and indoor workers, exercise in hot conditions, and preparedness.

A new study finds that projected future warming will result in El Niño events that grow at a faster rate, persist longer over the eastern and far eastern Pacific, and have stronger and distinct remote impacts.

April was a little cooler than average for the contiguous United States, and it was a month for extreme events, with tornadoes, blizzards, and wildfires.

Summary: The CHaMP Tool was designed specifically to address the substantive and communications needs of individuals developing hazard mitigation plans as required by FEMA.

A new study has found a link between red tides and dead zones along Florida’s west coast. When harmful algal blooms strike in early summer and persist into autumn, low-oxygen dead zones are also likely.

New climate modeling indicates an increase in flash flooding across most of the United States. Heavy rainfall events will likely cause more frequent and stronger flash floods by the end of the century.

Global warming will change Alaska’s precipitation. A new study projects changes in all warming scenarios, with the increases in both temperature and precipitation.
