Last month, Washington pledged to give up control of ICANN, a nonprofit that manages the Internet's domain name system. Critics say the move will empower repressive regimes to restrict Internet freedom. But it actually provides the best chance of preserving an open system.

We have come to appreciate that our rapidly increasing technological sophistication -- which has brought such benefits as safe and convenient air travel -- carries with it potential costs. It gives us greater ability to destroy, of course. But, it can also lead to the creation of vulnerable, tightly-connected, and inadequately resilient systems. And in those systems, individuals and organizations are often the weakest links -- as the recent Malaysia Airlines disaster makes clear.

As the United States redefines its role in the Middle East, regional powers will feel pressure to exercise restraint and cooperate with each other. And that is exactly what the UAE is doing by potentially striking a deal with Iran over the disputed islands of Abu Musa and Greater and Lesser Tunbs.

China’s recent announcement of an Air Defense Identification Zone in the East China Sea has generated a great deal of alarm. Much of that is a function of the fact that few know what an ADIZ is, what it is for, and why it matters -- including, apparently, the Chinese government and military.

Over the last several decades, human activities have so altered the basic chemistry of the seas that they are now experiencing evolution in reverse: a return to the barren primeval waters of hundreds of millions of years ago.

So far, public debate about the intervention in Syria has centered on the immediate scope and aims of any U.S.-led military operation, and whether the U.S. Congress should be involved. But no matter how the possible intervention and its aftermath play out, one thing is certain: the eastern Mediterranean -- where exploratory drilling has unearthed vast reserves of natural gas, and where competition between Cyprus, Egypt, Israel, Lebanon, Syria, and Turkey is already fierce -- will become less stable.

As of today, just 34 weeks into 2013, humanity’s demand for natural resources has exceeded the earth’s ability to renew them in a year. Welcome to ecological overdraft.

To stop climate change, the international community should shift focus from setting targets countries can’t meet to compelling multinational corporations to act. The immense power wielded by a small number of companies might be just what is needed to save the planet.

No matter what one thinks should be done about global warming, the fact is, it’s happening. And its effects are not all bad. In the Arctic, it is turning an impassible region into an emerging epicenter of industry and trade.

With predictions about climate change growing direr every week, geoengineering (which includes everything from fertilizing the oceans in an attempt to cajole great blooms of carbon-sucking phytoplankton to spraying particles into the upper atmosphere to make the earth more reflective) is starting to look more attractive. But the science still lags behind the ambitions. To understand how such schemes would work in practice -- and what their consequences would be -- it is time to start small-scale field tests.
