decades of foot-dragging by political leaders had propelled humanity into a critical situation, with greenhouse emissions rising faster than ever. Though it remains technically possible to keep planetary warming to a tolerable level, only an intensive push over the next 15 years to bring those emissions under control can achieve the goal

“If we lose another decade, it becomes extremely costly to achieve climate stabilization.”

It is increasingly clear that measures like tougher building codes and efficiency standards for cars and trucks can save energy and reduce emissions without harming people’s quality of life, the panel found. And the costs of renewable energy like wind and solar power are falling so fast that its deployment on a large scale is becoming practical

IS  is also gaining momentum in the struggle to control two natural resources that have defined the history of the Middle East – oil and water.

If control of oil has driven economic development in the modern Middle East, control of water has been a fundamental component of civilization itself. For decades, both the Syrian and Iraqi governments focused on hydrology in their bids for socioeconomic development, building a bevy of dams, canals and other infrastructure to control floods, improve agricultural irrigation and generate electricity for their populations. Denying or diverting water, though, was also tantamount to war. During the Iran-Iraq War (1980-1988) Saddam Hussein fretted that Iran would destroy dikes and dams on the upper Tigris River in order to cause flooding in Baghdad. In the early 1990s Syria and Iraq nearly went to war with Turkey over plans to divert part of the Euphrates River, and in 1992 Iraq famously cut off the water to the marshes of southern Mesopotamia in order to destroy the terrain where Shiite insurgents were hiding out. Punishing drought conditions in rural Syria may even have caused social unrest that helped precipitate the beginning of the March 2011 uprising.

In February 2013, IS took control of the Tabqa Hydroelectric Dam (Syria), once a showcase in Hafez al-Assad’s development plan and a major electricity source for Aleppo. Earlier this spring, IS opened up dikes around Fallujah to impede the Iraqi army as it tried to besiege the stronghold, causing flooding as far away as Najaf and Baghdad. With its recent advances, IS now controls the hydroelectric dam at Mosul, Iraq’s largest, and IS  is poised to take the dam at Haditha, the country’s second largest. With the tables turned, the Iraqi government finds itself considering a preemptive opening of the Haditha floodgates to block IS’s path.

Auguste Comte’s 19th century dream of a “social physics” that would “enquire into the present, in order to foresee the future, and to discover the means of improving it.” Historic events like the escalation of conflict and the achievement of peace, in the view of political forecasters, are just as predictable as more routine phenomena like election results or traffic patterns. They all obey the laws of political and social life, analogous to the laws of the natural world – or do they?

sophisticated vector-autoregression (VAR) models predicted routine events fairly accurately, but were far less accurate in predicting historic episodes like wars, uprisings and peace accords – the very events that political forecasters are most eager to anticipate.

Many of those historic moments involved “structural breaks,” a technical term that indicates shifts in the underlying parameters of the statistical model. These shocks to the system could not be extrapolated from prior data – they could only be identified as they occurred. All of this suggests that major historic events may not obey the same laws as the more routine events that precede them. Instead, major events can dissolve seemingly permanent laws of political and social life, initiating new patterns of interaction, for better or for worse.

Inequality within countries -- both rich and poor -- has been growing even as inequality between countries has been declining.

Poor countries -- especially big ones like China, India, Nigeria, Vietnam, Brazil, Turkey, and Indonesia -- have been opening their doors to the global economy and taking advantage of the opportunities it has to offer. Hundreds of millions of people have moved off of farms and into cities to take jobs in big factories and service operations. These businesses have adopted technology from around the world in an enormous feat of economic leapfrogging. They've packed a century of industrial development into just a few years.

absolute living standards have undoubtedly risen for a huge number of people
