In recent years, a new narrative has appeared on Chinese social media: that a warmer and wetter climate in Northwest China will herald a return to the “golden age” of the Tang dynasty (618–907 AD). 

Climate change will bring benefits, so the story goes, as historically China has flourished during warmer and wetter periods – conditions becoming common once more in the Northwest, a region extending from the province of Shaanxi to Xinjiang in the far west.

Every year, more than two billion farmers around the world work the land day in and day out to earn a living and produce what is needed to feed and clothe an ever-growing global population that reached 8 billion in November 2022. Though they bear the brunt of climate change on the front lines, many of the world’s farmers, ranchers and fishers are unaware of the international processes that affect their livelihoods.

Cairo hoped that COP27 would focus on its stated agenda: climate change adaptation. Yet it was human rights concerns—such as jailed pro-democracy activist Alaa Abdel Fattah’s hunger strike and rumors of restricted internet access to human rights platforms—that often stole headlines from climate policy or funding pledges. The persistence of human rights coverage demonstrated that Egypt and many other governments fail to recognize that strong governance, human rights protections, and climate change adaptation are mutually reinforcing and have overlapping policy actions.

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.

A key pillar of the UNFCCC was a commitment by industrialized nations to cover the incremental cost of climate change mitigation for developing countries. As part of this pledge, they agreed to mobilize $100 billion a year in climate finance by 2020 and maintain that level of funding up to 2025. While there are questions on whether this target has been met, climate finance has undeniably become one of the largest channels of wealth redistribution from developed to developing countries.

As climate change worsens, the once-unimaginable power to use technology to cool the planet—a method known as “solar geoengineering”—has quietly entered the realm of possibility. Yet the prospect of developing such planet-altering technologies has launched an intense debate: Can this be achieved responsibly? Should it be attempted at all?

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.

As Russia’s unprovoked assault on Ukraine continues, the world’s focus is rightfully on ending this conflict as soon as possible. But the global impact of a senseless war launched by a petro-dictator also calls for deeper reflection.
