Is it possible to prepare for the unexpected? Could anyone have foreseen, for instance, a nuclear meltdown triggered by an earthquake-induced tsunami? Or a brutal band of transnational militants quickly capturing Iraq’s largest dam while attempting to establish a new Islamic caliphate? Perhaps not exactly, but that shouldn’t stop us from anticipating unlikely events, says Chad Briggs, a risk assessment expert and strategy director of consulting firm GlobalInt.

In 1986, global nuclear weapons stockpiles peaked at nearly 70,000 warheads. By the beginning of 2013, there were just over 17,000, with only 4,400 kept operational. This dramatic reduction was the fruit of a negotiation process that began in the late 1940s. In spite of incredible tensions between the United States and the Soviet Union, negotiators were able to make progress once they focused on building trust with small, pragmatic steps, rather than starting with the complete elimination of all weapons. [Video Below]

The time has come for us to collectively reexamine – and ultimately move past – the concept of sustainability. The continued invocation of sustainability in policy discussions ignores the emerging realities of the Anthropocene, which is creating a world characterized by extreme complexity, radical uncertainty, and unprecedented change. From a policy perspective, we must face the impossibility of even defining – let alone pursuing – a goal of “sustainability” in such a world. It’s not that sustainability is a bad idea. The question is whether the concept of sustainability is still useful as an environmental governance framework.

Many existing water-sharing treaties should be re-assessed in the context of climate change, write Shlomi Dinar, David Katz, Lucia De Stefano, and Brian Blakespoor in a World Bank working paper.

Since 2005, the Reducing Emissions from Deforestation and Forest Degradation program (REDD+) has functioned as a mechanism to financially incentivize the preservation of forestlands in order to reduce greenhouse gas emissions. But beyond its original use, some organizations have also started exploring ways it can help with other development initiatives, like women’s empowerment. [Video Below]

To date, there have been two proposed responses to climate change: mitigation, aimed at stopping the buildup of greenhouse gases, and adaptation, focused on accommodating ourselves to a warmer world. There is a third option, however, that is increasingly relevant: suffering.

When Pakistan makes the news, more often than not it’s for one of two things: violent extremism or drone strikes. Adil Najam, a Pakistan expert and a lead author for the UN’s Intergovernmental Panel on Climate Change, says those headlines distract from a far more pressing security concern for the country: climate change.

Rapid population growth can be a contributing factor to climate change vulnerability and should be considered in climate adaptation and peacebuilding efforts, said the Wilson Center’s Roger-Mark De Souza at a workshop on climate change adaptation and peacebuilding hosted by the Institute for Security Studies (ISS) in Addis Ababa.
