Response to NOAA Statement

AMS Logo

The American Meteorological Society fully supports our colleagues at NOAA, who consistently put the safety of the American public first and foremost. They work tirelessly employing state of the art science to keep Americans safe. With respect to the press release that was issued by NOAA on Friday, 6 September, regarding the forecast of Hurricane Dorian, AMS believes the criticism of the Birmingham forecast office is unwarranted; rather they should have been commended for their quick action based on science in clearly communicating the lack of threat to the citizens of Alabama.

Prepare for more downpours: Heavy rain has increased across most of the United States, and is likely to increase further

                      Precipitation Map

Warming conditions mean more evaporation, which leads to more water vapor in the air. When rain-triggering conditions are favorable, more saturated air leads to heavier precipitation. This has been the story across most of the United States in the past century. Extreme precipitation events have grown more frequent since the start of the twentieth century, and such events are likely to become even more frequent over the twenty-first.

Adapted from Figure 2.6 in the Fourth National Climate Assessment (NCA4), these maps show observed and predicted changes in heavy precipitation events—those bouts of heavy rain or snow ranking among the top 1 percent (99th percentile) of daily events. All four maps use the same color scale. Percentage changes below 0 (decreases) are pale yellow, and increases appear in shades of pale green (smallest) to navy blue (greatest).

The maps of observed changes cover two time periods, 1901–2016 and 1958–2016, and display uniform percentage changes by region: Northwest, Southwest, Northern Great Plains, Southern Great Plains, Midwest, Southeast, and Northeast. Because the latter half of the twentieth century had denser weather station coverage, different methods have been used to calculate changes. The change from 1901–2016 reflects the difference between 1901–1960 and 1986–2016. The change from 1958–2016 shows the linear trend over that period. (The high-resolution image for 1958–2016 also shows observed changes in Alaska and Hawaii.)

RNRF Congress on Charting a New Course for the Mississippi River Watershed


December 3, 2019
American Geophysical Union
2000 Florida Ave. NW, Washington, DC 20009

RNRF is pleased to announce our upcoming congress on "Charting a New Course for the Mississippi River Watershed."

The Mississippi River watershed routinely experiences severe flooding events, causing damage to infrastructure, agriculture, the economy, and the environment. Now, climate change is exacerbating this flooding, guaranteeing that the situation will only get worse in the future. A new, radical course needs to be charted. RNRF congress speakers and delegates will discuss impacts of the new climate normal, reimagine management for different sectors of the watershed, and examine the stubborn and long-standing impediments to sustainably managing resources within the watershed.

Registration will open in the coming weeks. Mark your calendars!

RNRF 2019 Award Announcements

RNRF congratulates the winners of its annual awards in Sustained Achievement, Outstanding Achievement, and Excellence in Journalism. The awards will be presented at the annual meeting of the RNRF Board of Directors in Potomac, Maryland on November 12, 2019.

Outstanding Achievement

USACE logoEWN logo

The U.S. Army Corps of Engineers’ Engineering with Nature (EWN) program is the recipient of RNRF’s 2019 Outstanding Achievement Award. This award recognizes a project, publication, piece of legislation, or similar concrete accomplishment in the natural resources field.

Since 2010, the EWN initiative has contributed to the understanding and implementation of approaches to integrate natural resources systems with conventional infrastructure to deliver more sustainable and resilient solutions. In January 2019, the EWN initiative reached a significant milestone with the release of Engineering with Nature: An Atlas, which showcases 56 projects from around the world illustrating the principles and practices of engineering with nature.

The USACE began its EWN program with the expressed purpose of promoting, “the intentional alignment of natural and engineering processes to efficiently and sustainably deliver economic, environmental and social benefits through collaborative processes.” The EWN program includes communication, research and development, and demonstration activities organized to promote four key elements in infrastructure project development and execution:

• Using science and engineering to produce operational efficiencies;
• Applying natural systems and processes to maximum benefit;
• Broadening and extending the benefits provided by projects to include economic,
environmental and social benefits; and
• Employing science‐based collaborative processes to engage, organize and focus interests,
stakeholders and partners.

Raising public awareness and adoption of the principles and practices of engineering with nature has been a core feature of EWN from the start. Just within the past year, in addition to releasing the Atlas, the EWN team has conducted more than 10 workshops, short courses, presentations, and other meetings to promote engineering with nature, including a briefing on Capitol Hill and an 8‐hr. short course during ASCE's International Conference on Coastal Engineering in July 2018.
