For the first time in the history of the World Economic Forum’s Global Risks Report, environmental concerns — including water crises, failure to adapt to climate change, and biodiversity loss — dominate the top long-term risks. The report underscores systemic and potentially disruptive geopolitical risks related to the environment, and asserts the window for response is closing. 2020 promises to be a year of reckoning, culminating with the G20 meeting, which will be held in the desert city of Riyadh, Saudi Arabia (pictured above) where heads of government will debate many of the report’s gravest risks.
