The looming 27^th meeting of the Conference of the Parties (COP) of the UNFCCC in Egypt in November 2022 brings with it a moment of truth for many nations. They must intensify decarbonization efforts to meet their share of global commitments agreed upon at the Paris COP. Yet, the already significant challenges also have intensified. Disruptions of oil and gas flows caused by Russia’s invasion of Ukraine are slowing a global green energy transition—at least in the short-term. The depth of the crisis means countries are even scrambling to keep coal-powered plants working.

Climate security is an essential conceptual framework to understand the global interplay of biophysical and socioeconomic forces that threaten our planet. Indeed, it is so important that new currents of science, politics, and advocacy make refining definitions a necessity.

Hydropower is the largest source of low-carbon electricity in the world today. And its benefits are needed more than ever. The International Energy Agency estimates that we will need to double the amount of installed hydropower capacity—which stands today at around 1360 gigawatts worldwide—in order to limit the rise in average global temperatures to 1.5 degrees Celsius above pre-industrial levels.

Meeting the immense impacts of climate change will require strong “top-down” policies to reduce emissions and remove carbon from the atmosphere, as well as building resilience in the face of climate stresses and shocks. As communities and governments undertake rapid and fundamental transformation of sectors and systems—energy, transportation, buildings and even green spaces—the need for governments to develop strategies that drive innovation and technological solutions becomes more urgent and essential.

The much-needed transition to a zero carbon, green economy offers opportunities to contribute to peace, but only if the conflict risks of transition are understood and managed to produce a just and peaceful transition. That means minimizing “backdraft”—the unintended negative impacts of transition that are a key obstacle to that goal.

Ever since the CNA’s Military Advisory Board—composed of former U.S. military personnel—named climate change as a “threat multiplier” in a 2007 report, the term has gained widespread currency both in environmental and national security circles. It also has propelled the need to assess and address climate-related security risks higher up overall policy agendas.
