According to recent polling, climate change is seen as the single most threatening international challenge around the world, and there’s evidence that all that worry is taking a psychological toll. Adding to droughts, floods, extreme weather, and die-offs, psychologists are observing higher levels of anxiety, depression, and post-traumatic stress disorder in certain areas and professions. Even people who do not actively stress about global warming or view it as a major threat may still suffer psychological trauma from its effects.

Isabel dos Santos, the daughter of Angolan President José Eduardo dos Santos and the richest woman in Africa, owes her wealth to the oil industry. Delfina Fernandes, a woman living in abject poverty in the village of Kibanga, uses gasoline as an anesthetic to dull the sheering pain of her rotting teeth.

Opportunities for research, enterprise, and exploration in the Arctic are expanding as climate change renders the northernmost reaches of the globe more accessible – and visible – than ever before. Often overlooked, however, are the people who actually live there. Four million people make their home in the resource-rich Arctic, where developers and policymakers are staking growing claims. [Video Below]

Somewhere off the coast of Thailand, “ghost ships” bump and crash along the choppy waves scrapping the sea floor with nets that spare nothing. Pulling up these illegal hauls in shifts that sometimes last 20 hours are thousands of migrant fishermen, many of whom have been forced into indentured servitude or kidnapped. Far from shore on unregistered boats, they have little hope of escape and face daily abuse and squalid conditions. More recently, some captains have turned to trafficking Rohingya fleeing persecution in Myanmar, pressing some into service, extorting others, and taking sex slaves.

Ten years ago this month one of the United States’ deadliest and most costly storms, Hurricane Katrina, struck the Gulf Coast. In Louisiana, the storied city of New Orleans was dealt a particularly devastating blow. Hundreds died and the city suffered extensive damage as 80 percent of its neighborhoods flooded, prompting an exodus it is still recovering from.

As the world prepares for a pivotal climate conference in Paris this December, countries are offering their national plans to tackle a changing climate. These plans, known as intended nationally determined contributions (INDCs), contain details of what each country is prepared to do as part of a new global climate agreement. While the public focus is often on mitigation – how much countries are willing to reduce emissions, by when, and with what degree of transparency – adaptation to the impacts of climate change demands the same level of attention. In fact, the last round of international climate talks in Lima invited parties to include adaptation in their INDCs.

The World Economic Forum recently named water crisis the world’s number one risk for the next 10 years for its potential impact on people and industry. Indeed, as the global community grapples with climate change – and environmental change of all kinds – understanding the fundamental nature if water to human society is crucial. The input report for this year’s World Water Week, released yesterday by the Stockholm International Water Institute, in fact argues that getting water management right is a prerequisite for sustainable development.
