Clean Energy & Climate Change

APS asks members of Congress to review the Department of Defense’s report on the effects of climate change and arrange follow-up meetings to discuss its findings with APS members and/or other members of the scientific community.

Section 335 (A) of the 2018 National Defense Authorization Act (NDAA), which passed with large bipartisan support, specifically states that “climate change is a direct threat to the national security of the United States.” Furthermore, the NDAA mandates that the military write a report by the end of 2018 examining the effects of climate change on military installations and where a changing climate could threaten global and regional stability.

This report was officially released in January of 2019. It states that more than half of the Department of Defense’s 79 mission assurance priority installations are currently vulnerable to climate-related events such as flooding, drought, and wildfires. Approximately another quarter of them could become vulnerable within 20 years. The report concludes by stating that future vulnerability analyses would likely reveal an uptick in vulnerabilities if adaptation strategies are not implemented.

APS would like Congressional offices to review the Department of Defense’s climate change report and arrange follow-up meetings with APS member constituents and/or other members of the scientific community to discuss its methodology, findings and proposed actions moving forward.

Take Action on Clean Energy & Climate Change


The Impact of Personalized Emails

Although personalizing your email with your own experiences and anecdotes may take a few extra minutes, research shows that it is well worth the time. According to a Congressional Management Foundation survey, individualized emails are the second most effective method overall for positively influencing a member’s decision on an issue. Individualized email messages are also 64% more effective than form email messages.

Furthermore, 83% of congressional staff surveyed said that it would take more than 50 form emails for them to consider taking the action requested. On the other hand, 70% of staff said that it would take less than 50 personalized emails for them to consider taking action. We encourage you to personalize your emails to Congressional members in order to maximize the impact of your voice.

Greenhouse Gas Inventory Project

In 2015, the American Physical Society (APS) released its Statement on Earth’s Changing Climate. As a follow-up activity, the Society conducted an internal analysis of its day-to-day operations and select associated activities to determine its 2015 Greenhouse Gas (GHG) inventory, or carbon footprint. The GHG Inventory Advisory Committee oversaw this project and provided a set of recommendations to the APS CEO aimed at reducing and/or mitigating the Society’s GHG emissions.

Helium Issues

Helium is essential for achieving the extremely cold temperatures required by many current and emerging technologies as well as for advanced scientific research. The demand for helium has been steadily increasing, and there is every reason to believe that this will continue. In view of the importance of this irreplaceable resource, measures must be taken to conserve and advance the nation's helium reserves.
