The summer of 2022 has been a season of climatic extremes across the globe, including record-breaking heatwaves and droughts in both the United States and Europe. But even these unprecedented extreme weather events pale in comparison with China’s heatwave from hell. For more than two months, a huge swath of the world’s most populous nation has been baking under temperatures of up to 113 degrees Fahrenheit. According to state media, this extreme heatwave affects an area of over 500,000 square miles, equivalent to more than twice the size of Texas. In terms of duration, intensity, and area affected, it is almost certainly the most severe heatwave ever recorded anywhere in the world.

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.

As Russia’s war in Ukraine continues and nations are returning to behaviors best explained by realism, we are wrestling with these trends’ longer-term implications on water diplomacy. States are becoming inward-looking and prioritizing national sovereignty. Debates about water and climate are resurfacing, and we should better understand how hard power and inward-looking approaches can impact water diplomacy and cooperation. To inform policymakers about power sensitivities and power games played in diplomacy, water diplomats must rethink the future of water security and peace. They should reexamine leadership styles, cultural sensitivities, and knowledge exchange from the lens of realism.

From climate change to COVID-19 and the war in Ukraine, the world is a landscape of increasing instability. Book-ending the Top 5 posts of June are two articles that explore different aspects of these converging risks. In the top post for June, Steven Gale and Mat Burrows write that globally, younger generations are becoming increasingly disengaged and discontent with their democratic governments, civil society, and institutions. Youth disillusionment is not a result of ignorance to current affairs, but rather a lack of faith in democratic institutions to address today’s most pressing global issues. Tackling youth disillusionment, suggest Gale and Burrows, begins with examining youth engagement trends and placing it at the top of the agenda.

As we face the twin crises of biodiversity loss and climate change, natural resource management is now more critical than ever—especially in the protection of one of our most precious resources: water.

The stakes of getting it wrong couldn’t be higher: increasing economic inequities and substandard public health for a growing population. And the evidence that such issues have won the attention of political leaders is increasing, with the June 2022 introduction of a White House Action Plan on Global Water Security that links this crucial issue directly to U.S. national security and offers pathways and proposed resources to advance progress broadly on multiple fronts.

Hydrogen fuel is becoming a central pillar of global decarbonization strategies. The hype over green hydrogen (the “fuel of the future”) and its potential to provide an abundance of low carbon fuel to transportation and industry has enticed several major emitting countries to scale up its production. And a UN-backed initiative wants to achieve a 50-fold production increase in the next six years.

Speaking at a session at the 2^nd International Conference on Environmental Peacebuilding in February, Guillaume Pierrehumbert, head of the Water and Habitat Unit of the International Committee of the Red Cross (ICRC) called for “a comprehensive rethink of collective humanitarian action” to address the unprecedented civilian crises in protracted armed conflicts.

When considering the potential effects of “backdraft” on climate change responses, the question of the world’s water future may be the most salient of all—especially as we examine water supplies and freshwater ecosystem health.
