New planet-changing geoengineering technology is available to help humanity combat an existential security threat. However, like atomic fission, this technology is not to be jumped at without caution.

This year is the seventy-fifth anniversary of the Baruch Plan. Almost no one knows this, or if they do, they probably don’t remember who Bernard Baruch was, or what his eponymous plan was for. But the Baruch Plan of 1946 was our first and last real attempt at world governance of nuclear weapons. Three-quarters of a century later, the ill-fated effort carries important lessons for addressing the crisis of climate change.

That future wars will be fought over water, rather than oil, has become something of a truism, particularly with regard to the Middle East. It’s also one that most water experts have refuted time and time and time again. But while this preference for cooperation over conflict may (and emphasis on may) remain true of interstate disputes, this blanket aversion to the ‘water wars’ narrative fails to account for the rash of other water-related hostilities that are erupting across many of the world’s drylands. As neither full-on warfare nor issues that necessarily resonate beyond specific, sometimes isolated areas, these ‘grey zone’ clashes don’t seem to be fully registering in the broader discussion of water conflicts. In failing to adequately account for the volume of localized violence, the world is probably chronically underestimating the extent to which water insecurity is already contributing to conflict.

The last decade was the warmest on record, with 2020 tied with 2016 for the all-time high average annual global temperature. This 10-year period also saw armed conflicts at severity levels not seen since the Cold War era. Could there be a causal link between these trends?

To the frustration of policymakers and laymen alike, empirical research has been unable to provide a simple and coherent answer to this question. Instead, studies of climate-conflict connections have for a long time continued to produce diverging findings and – occasionally – inspired heated debates. So, where do we stand?

In a review article introducing a new special issue of the Journal of Peace Research (JPR) on the security implications of climate change, we assess the nature and extent of scientific progress in climate-conflict research over the past decade. As yardsticks for measuring progress, we identify seven key research priorities frequently advocated in earlier reviews of the quantitative literature. 

When the dust settles after wars and armed conflicts, people are eager to rebuild their lives and livelihoods in the wake of the devastation wrought upon their country. Often one issue is largely absent in post-conflict reconstruction and development planning: addressing conflict-linked destruction of the environment. 

Early predictions about COVID-19’s impacts on Africa suggested that the continent would be a disaster zone marked by weak medical systems collapsing under strain and undemocratic states failing to provide social services to destitute populations. These predictions did not come to pass. Instead, many countries across the continent stepped up early on to join the world in curtailing the spread of COVID-19. The second order effects of the virus have been significant, however. Despite the low numbers of infections and deaths, lockdowns and the decline of a large percentage of informal trade and commerce in Sub-Saharan Africa have sent the region’s economy into recession, with increased inflation rates, widespread unemployment, and increased food insecurity. It’s within this context that collaboration (internationally and within the continent, between governments, the private sector, and local communities) to protect the environment—and by extension enhance livelihoods, promote sustainable development, and achieve enduring peace—has taken new forms.

“One of the most important accomplishments of the MEDEA program was to convince the intelligence community that near-term climate change is important for national security,” said D. James Baker, former Administrator of the National Oceanic and Atmospheric Administration (NOAA) and member of the MEDEA Program, at a panel at the American Geophysical Union’s virtual 2020 Fall Meeting. Organized by ISciences LLC’s Tom Parris, CASE Consultants International’s Eileen Shea, and Columbia University’ Robert Chen, the panel focused on how to build an effective knowledge-to-action enterprise that helps policymakers and society respond to emerging eco-security challenges. (See below for links to short, pre-recorded videos panelists shared prior to the panel to inform the discussion.)

For most of 2020, news, politics, policy, and research in the United States and abroad were dominated by the challenges posed by COVID-19, a rapidly unfolding global pandemic unprecedented in scale and cost. For much of the world, however, COVID-19 in fact competed with many other highly destructive events including a cascade of environmental disasters. Swarms of locusts pushed much of the Horn of Africa into or close to famine; 30 severe storms including Hurricanes Iota and Eta battered the Atlantic coasts; some 4 million acres of forest burned to the ground in California, doubling the previous high reached in 2018; typhoons ravaged the Philippines; floods overwhelmed parts of Indonesia; and many regions around the world experienced devastating heat waves. In addition to disaster patterns, the trends in violent state conflict were equally alarming, reaching their highest level since the end of World War II, according to a 2020 report on conflict trends from PRIO. In the most violent conflicts, in Syria and Yemen, the impacts of war have been amplified and complicated by the impacts of drought and years of environmental mismanagement.
