When Valerie Hudson evaluates the strength of a nation, whether food security, wealth, peacefulness, or quality of governance, she finds one important thread that underlies it all. “One of the most important factors in the determination of these things is in fact the situation, and security, and status of women,” said Hudson at the Wilson Center on June 24. [Video Below]

Karachi, the world’s second largest city by population, is emerging from the grips of a deadly heatwave. A persistent low pressure system camped over the Arabian Sea stifled ocean breezes and brought temperatures in excess of 113°F (45°C) to the city of 23 million people in June. The searing heat disrupted electricity and water service, making life nearly unbearable. All told, officials estimate the heatwave killed at least 1,200 Pakistanis, more than twice as many as have died in terrorist attacks this year.

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.

Between the Sahara to the north and savanna to the south lies the semi-arid Sahel, a region stretching from Senegal to Sudan that has experienced desperate poverty, climate change, malnutrition, and violence. While every context is different, the Sahelian countries share some common challenges, including a pattern of recurring crises and fluid borders. Boko Haram’s reign of terror in northern Nigeria and Mali’s coup have both had cross-border components. [Video Below]

The Sustainable Development Goals are expected to be adopted in New York in September and expectations for the UN Climate Summit in Paris are higher than perhaps any other time. “It is a critical year,” said Alan Hecht, director for sustainable development for the U.S. Environmental Protection Agency, “but our challenge is years of sustainable development. How do we take actions today, how do we prepare for the future in such a way that we will achieve a more sustainable outcome?” [Video Below]
