In recent years, many foreign affairs experts have attempted to demonstrate the linkages between climate change and the social tensions that can lead to conflict. While critics may believe this is simply a fad in international affairs, history suggests otherwise. Over the last few millennia, climate change has been a factor in conflict and social collapse around the world.

With Russia and China advancing on their neighbors, now is not the time for a US promise never to launch a first nuclear strike.

No country owns the North Pole or the expanse of the Arctic Ocean surrounding it. The Arctic region has a population of about 4 million, including more than 30 distinct groups of indigenous people using dozens of languages; they have lived there for more than 10,000 years. The area also has a unique and diverse ecosystem that includes fish, marine mammals, birds, land animals, and a thriving web of bacteria, viruses, algae, worms, and crustaceans that live in sea ice.

Proponents say the new low-yield warhead adds flexibility and closes an “exploitable gap” in US capabilities. In reality, it’s a half-measure that only confirms a US reluctance to commit resources.

As another mosquito-borne virus spreads rapidly, we should consider how to prevent the next one.

To assure global coverage and a higher probability of detecting nuclear tests, if the international community must expand its monitoring system and put limits on radioactive releases from nuclear facilities

When I moved to a neighborhood known as the "murder capital" of New York City, I figured it was only a matter of time before someone held a knife to my throat and demanded my wallet. I would hand it over, of course. It's only money, right? But it didn't happen like I thought it would. I left a Christmas party late one night and heard someone running behind me as I approached a subway entrance. When I whirled to look, I was struck with a heavy object. I tumbled down the staircase and scrambled to my feet -- still in possession of 30 cents and two subway tokens.

Allegations of Iran-North Korea nuclear cooperation pop up repeatedly, but have no basis in fact.

Despite doubts about credibility of NATO or US security guarantees, a European nuclear force would still bring more risks than benefits.

In previous columns, I've discussed the consequences that will result during a pandemic or bioterrorist attack from not insuring all Americans and providing adequate primary care--see "The Security Impact of the Uninsured" and "The Exodus of General Medical Physicians." What I haven't discussed is that the U.S.

Most students do not have a strong understanding of what nuclear weapons are, their destructive power, or their role in the international order, and even fewer have a sense of how many nuclear weapons exist.

China will likely constrain its nuclear expansion if the United States pledges to limit its missile-defense plans.

Widespread societal and behavioral changes are necessary to reduce carbon emissions, but global inequality is standing in the way.

Unproductive blame shifting has dominated the nuclear debate in recent years, frustrating progress and serving only the interests of those who are content to see no movement on nonproliferation and disarmament. Rekindling a spirit of common purpose on the nuclear agenda is an urgent task. Despite the post-Cold War decline in public attention, the consequences of nuclear weapons proliferation and an indifferent international performance on nuclear disarmament remain potentially catastrophic.

For the information environment to thrive, investments in data access, standardized measurements, and research tooling are needed.

A new NATO special report concludes that climate change will make things worse in the world's most unstable regions.

An incremental approach could move the region beyond weapons-of-mass-destruction gridlock.

Although Washington should keep working to bridge the divide with Riyadh, the United States also needs to begin planning for a scenario in which it is unable to reach an acceptable nuclear cooperation agreement. The key for the United States, in the parlance of negotiating strategy, is to know its BATNA, or “Best Alternative to a Negotiated Agreement.” If the Saudis don’t bend, the United States will have options to safeguard US interests, including, for example, increased US intelligence on Saudi’s nuclear program and clear guidelines for when sanctions might be imposed should the Saudis move toward uranium enrichment.

The TVA used to be at the forefront of new technology. Not anymore.
