Groundwater is relied upon for roughly half of global drinking water. And as climate change alters precipitation patterns and pollution of surface water continues to increase, our collective dependence on groundwater is likely to increase.

Getting ahead of the potential conflicts, or in some cases, catching up with them, requires an increase in effective groundwater cooperation and diplomacy. Yet the vast majority of transboundary aquifers exist without any form of agreement among the states that share them. This state of affairs leaves the aquifers—and the people who rely upon them—vulnerable to overexploitation, environmental degradation, and the risk of interstate conflict.

Organizing Regional Action on Climate Change, Health, and Environment

As the 2030 deadline for the Sustainable Development Goals looms, the World Health Organization has proposed a new regional framework that aims to build climate-resilient and sustainable health systems, improve the health sector’s access to climate funding, and build an evidence base for policymaking.

I flew into Tel Aviv last Friday afternoon, primed for a week of meetings with Israeli and Palestinian environmentalists and officials. By sounding out these men and women in Jerusalem, the West Bank, and other parts of the region, I hoped to expand on past explorations of their transboundary cooperation, widely recognized as a model for environmental peacebuilding. Through an articulation of the successes that they––and their Jordanian peers–have had in bolstering water access, renewable energy, and environmental protection across their shared natural landscape, I was looking forward to telling a positive environmental conflict story—particularly one in a place that is often bereft of good news.

Extreme heat from climate change threatens food security in the world’s two food-producing superpowers. Climate adaptation for agriculture is a must. The US and China have much to share on climate-smart farming practices to help us both weather the storms and droughts. 2023 brought scorching heat waves that baked crops and livestock in China and the United States. In China, farm animals and fish died from extreme heat in June with some provinces enduring weeks of temperatures above 40°C (104°F). In one farm, a heatwave-triggered power outage resulted in hundreds of pigs suffocating to death after shed fans stopped working.

More than 11,300 people are confirmed to have died in the floods that struck eastern Libya on September 11, 2023, far surpassing many estimates of the death toll in the country’s 2011 civil war. Thousands are still missing. Flooding has washed away approximately 25% of the city of Derna, and damage to roads and bridges is curtailing emergency service access. A rapid attribution study estimated that the extreme rain was at least a “1-in-300 year event.” This is far beyond previously recorded incidents, yet such incidents are now up to 50 times more likely—and up to 50% more intense—when compared to a 1.2°C cooler climate.

In Hawaii and elsewhere in the North Pacific, few hatchlings are emerging from the nests of endangered hawksbill and green sea turtles. In Wisconsin, some tree swallows have failed to produce offspring. In California, infectious diseases are now more common in southern sea otters. In Michigan, bluegills are swimming slower. In the Arctic, some hooded seals and their pups have thyroid problems. And in North Carolina’s Cape Fear River, American alligators have been found with lesions and unhealed, infected wounds.

A Warming World is Accelerating the Spread of Dengue

Dengue is now endemic in most Latin American countries. But scientists warn that a warming climate is increasing the pace of breeding and transmission of dengue-carrying mosquitoes, and bring them into new countries.
