The End of Pasta?

All of the major grains – rice, corn, and wheat – are already suffering from global warming, but wheat is the most vulnerable to high temperatures. That, however, does not mean that there will be less of it – or of other agricultural crops – as global temperatures rise.

PRAGUE – Scare stories have been an integral part of the global warming narrative for a long time. Back in 1997, Al Gore told us that global warming was making the El Niño winds stronger and more severe. That has not happened. Greenpeace and many others have told us for years that we will see more violent hurricanes. In fact, over the last six years, global hurricane energy has dropped to its lowest level since the 1970’s, while the United States has had the longest absence of severe hurricanes ever (Sandy was a “superstorm,” not a hurricane, when it hit the vulnerable East Coast in October).

But the scares do not stop there. The World Wildlife Fund declared in 2004 that polar bears would go extinct by the end of the century, and that the calamity would start in Hudson Bay, where they would stop reproducing by 2012. The bears are still reproducing. And stories abound of global warming bringing malaria to Europe or Vermont. But here, too, the evidence contradicts such fears; in fact, malaria deaths have dropped more than 25% over the last ten years.

It is understandable that pundits, worried about global warming and frustrated with the near-absence of political interest or solutions, see exaggeration as an easy way to garner attention. The problem is that when these scare stories are later shown to be wrong, people become less willing to listen even to reasonable arguments about global warming. Indeed, skepticism about global warming has gone up, not down, as the false alarms have become increasingly high-pitched.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
