Earth’s thin upper-crust of soil is kept in balance by a complex carbon and nutrient cycle that is increasingly threatened by human exploitation and climate change, according to a review in Science. The chemicals trapped in topsoil and subsoil are crucial to plant growth, but are being depleted at rates much higher than they are being replenished, writes Ronald Amundson et al. For instance in the central United States, estimated soil erosion rates exceed production rates by 10 times.

“Tackling climate change could be the greatest global health opportunity of the 21^st century,” asserts the newest report by the Lancet Commission on Health and Climate Change.

Pope Francis sparked worldwide discussion and jubilation among many green advocates after releasing Laudato Si, the first Papal encyclical to focus directly on the environment. The pontiff touched on everything from pollution and sustainable development, to anthropogenic climate change and water security in his 180-page missive.

In their first annual report, the ResilientAfrica Network (RAN), a partnership of 15 African universities, Tulane University, Stanford University, and the Center for Strategic and International Studies, outlines efforts to explore and define multiple “pathways of vulnerability” in sub-Saharan Africa. The report acknowledges that these pathways can be very different from place to place, but by working with African communities more closely, they hope to find new ways to break cycles of chronic crisis. One of the interventions piloted by Stanford was “deliberative polling,” which is  based on the premise that communities are more likely to respond to development interventions if they understand the logic behind them and are involved in the process.

When the leaders of the G7 countries – Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States – met earlier this month, they agreed to make fossil fuels a thing of the past by 2100. At the same time the G7 is also taking steps to make climate change’s connection to conflict a priority in the present.

With thousands of scientists representing 195 countries working for more than a quarter of a century, the Intergovernmental Panel on Climate Change (IPCC) is the world’s leading authority on of assessing climate change and its potential socio-economic impacts. However, Marc Levy, an IPCC lead author and deputy director of Columbia University’s Center for International Earth Science Information Network, says he’d have gone further in connecting climate change to conflict in their latest report if it were up to him.

The world is more connected than ever before, but also more complex. Big, transnational trends like climate change, urbanization, and migration are changing the calculus of geopolitics, while local-level inequalities persist. “[Change] seems to be spinning around us so fast,” said John Hempelmann, president of the Henry M. Jackson Foundation, which honors the legacy of the late senator from Washington State. How can today’s and tomorrow’s leaders adjust to global trends? [Video Below]

Millions of people across the Middle East face drought, scarce drinking water supplies, and poor sanitation due to civil wars and conflict. Meanwhile, resource constraints and foreign military interventions risk more severe humanitarian disasters.
