DHS Hurricane Mitigation: Project HURRMIT and HAMP

January 2010

The back-to-back devastating hurricane seasons of 2004 and 2005 suggested that hurricanes might be a threat to national security, especially as the climate warms, and by 2008, the Department of Homeland Security (DHS) began investigating ways to work with scientists to not only mitigate on-land damage from hurricanes, but possibly to reduce their intensity or alter their paths. In February of that year, DHS' Science and Technology Directorate sponsored a workshop with NOAA’s Earth System Research Laboratory to identify viable paths to take. The conclusions of the workshop, published in March 2008, were to embark on a modest plan of action: Develop models of certain concepts, narrow those to a few for further testing, and then narrow further to determine one concept that would be worthy of first small-scale and then larger-scale testing.

After the workshop, DHS began by creating Project HURRMIT, an effort to model and determine the effectiveness of some of the most promising hurricane mitigation ideas, such as cloud seeding or wave-driven upwelling pumps, based on numerical simulations and actual historical hurricane data. DHS had also established a separate department-wide program in 2009, called FutureTECH, which was aimed at establishing partnerships between the federal government and the private sector, national laboratories, university scientists and other research groups to develop cutting-edge technologies in line with the department’s assessment of its future needs. Although largely focusing on detecting human-made threats, one of FutureTECH’s areas of “innovative research” was on hurricane mitigation.

But although the modeling has continued, DHS has pulled back from its plans to investigate new technologies and field tests for weather modification. One reason, says William Laska, program manager at DHS' Science and Technology Directorate, may be that the terms “geoengineering” and “weather modification” are still distasteful to both scientists and members of other government agencies. When DHS began approaching these different groups about the possibility of investigating and funding technologies for hurricane modification, “waving the modification/mitigation flag, we got a lot of doors slammed in our face,” Laska says. Furthermore, he adds, “there’s still a sour taste from Stormfury” — a government project that lasted from the early 1960s to the early 1980s and investigated the possibility of seeding clouds with silver iodide to weaken tropical cyclones, but produced inconclusive results.

As a result of this resistance to federal research into geoengineering, Laska says, DHS decided to focus more on basic research to understand hurricanes — particularly the impact of aerosols and cloud microphysics — rather than on developing technologies or methods to modify them. That dovetails nicely with NOAA’s hurricane prediction research, he says, because NOAA hasn’t done a lot of research specifically into aerosols' effect on hurricanes. “The knowledge we’re gaining is going to better help NOAA predict changes in hurricane intensity, and give the [Federal Emergency Management Agency] more time to evacuate people, to do what they need to do,” Laska says.

But this focus on basic research could one day lead the government back to geoengineering. As part of its new effort, DHS has enlisted six scientists, including retired NOAA scientist Joseph Golden, who worked on Project Stormfury, to participate in its Hurricane Aerosol Microphysics Program (HAMP). In May, Golden outlined the HAMP project at the American Meteorological Society’s conference on Hurricanes and Tropical Meteorology in Tucson, Ariz. He emphasized that HAMP is in an early stage and will focus on gathering observations and running model simulations. Only if the results are promising, he noted, might “later phases” of the program include actual storm seeding trials. Laska, cautiously, confirms those plans, but emphasizes that “we want to keep away from saying we’re modifying hurricanes.” [1]

An Act To End Atmospheric Experimentation Without Notification

Our solution is an addendum to the international weather warfare ban requiring two things:

• TRANSPARENCY: a worldwide requirement to give 48 hour notice before modifying or experimenting in our sky or surrounding atmosphere.
• VERIFICATION: create a worldwide citizen-powered sensor network to monitor atmospheric conditions, record video footage of sky conditions, analyze rainfall samples, and display atmospheric aerosols in real-time on a publicly available website.
