Notations From the Grid (Weekly Edition): On #Climate

#COP25 has been going on in Spain.     We look forward to releasing comments on it as we wanted to report on this for this edition of Notations on the eve of the weekend:

Highlights From Drought and Outdoor Recreation Seminar

The outdoor industry is responsible for 2.2% of national GDP; however, projected increases in the frequency and severity of drought threatens the viability of water-based recreation businesses. NIDIS, in partnership with the University of Colorado's Master of the Environment Graduate Program, hosted a seminar on November 19 to explore the effects of uncertain snowpack levels, streamflows, and warming temperatures on outdoor recreation businesses with a focus on snow- and water-based activities (skiing, fishing, rafting, etc.).

FEATURED News & Updates

Indo-Pacific Ocean Warming is Altering Global Rainfall Patterns New research by NOAA shows that warming of the Indo-Pacific Ocean is altering global rainfall patterns, contributing to declines in rainfall on the US west and east coasts. The study, published in the journal Nature, reports a doubling in the size of a warm pool of water spanning the western Pacific and eastern Indian Ocean in recent years. The expansion is changing a key weather and climate feature called the Madden-Julian Oscillation, influencing everything from monsoons in India to heat waves and flooding in the United States.

Drought Planning Guide Falling Dominoes: A Planner’s Guide to Drought and Cascading Impacts is now available as a free download from the American Planning Association (APA). This guide makes the case for establishing drought as a priority for local planning. Planners are central in influencing land-use patterns and helping communities guide how development and redevelopment occur. The report is a result of a collaboration between APA and the National Drought Mitigation Center, with support from the Federal Emergency Management Agency. Learn more >

Citizen Science Condition Monitoring Citizen scientist's knowledge about local weather can reveal much more than can be learned from recording daily rainfall alone. With all the extra eyes and ears out there, Condition Monitoring reports provide context to conditions. Learn about Condition Monitoring for the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) and new regional guidance, both developed by the Carolinas Integrated Sciences & Assessments (CISA) with support from CoCoRaHS, NDMC, and NIDIS.

FEATURED MAP + DATA National Snow Analyses

Winter is still weeks away. However, for much of the United States, it feels like it's already here with the recent cold temperatures and snowfall. The National Weather Service's National Operational Hydrologic Remote Sensing Center produces maps and offers data for snow water equivalent, snow depth, average snowpack temperatures, snow water equivalent change, snow/non-snow precipitation, snow melt, sublimation, and snow reports. Additionally, station reports and interpolated snowfall products are available. Learn more >
