Ocean heatwaves dramatically shift habitats 5 August 2020

Ocean heatwaves dramatically shift habitats

“Thermal displacement” reflects how far species must go to follow preferred temperatures

Marine heatwaves across the world’s oceans can displace habitat for sea turtles, whales, and other marine life by 10s to thousands of kilometers. They dramatically shift these animals' preferred temperatures in a fraction of the time that climate change is expected to do the same, new research funded by NOAA's Climate Program Office shows.

New research identifies regions with worsening "snow droughts" around the world 3 August 2020

New research identifies regions with worsening "snow droughts" around the world

Western United States snowmelt deficit found to be of increasing intensity and length in recent years

Snow is used by approximately ⅙ of Earth’s population for drinking, agriculture, and hydropower, among other uses. Despite its importance, “snow droughts,” or deficits in snowmelt, which can have serious regional and global consequences, have been fairly unexplored compared to other forms of drought, until now.

Researchers show consistent upper air temperature trends for the first time, improve understanding 30 July 2020

Researchers show consistent upper air temperature trends for the first time, improve understanding

Obtaining consistent results from data records that span multiple types of observing systems has been challenging, limiting our ability to use the observations and realize their full value.

No consistent ENSO response to volcanic forcing over the last millennium 14 July 2020

No consistent ENSO response to volcanic forcing over the last millennium

In a recent paper published in Science, authors analyze new paleoclimate data in the form of coral samples from the Tropical Pacific. These include a consistent proxy record for variables such as sea surface temperature.

Urban Northeast RISA contributes to assessment of green infrastructure for reducing risk during Hurricane Sandy 14 July 2020

Urban Northeast RISA contributes to assessment of green infrastructure for reducing risk during Hurricane Sandy

As NOAA promotes green and natural infrastructure, it is helpful to understand the specific arrangements that provide co-benefits to communities.
