Несложная климатическая задача

НЬЮ-ЙОРК – В следующем месяце, подписавшие в 1989 году Montreal Protocol on Substances that Deplete the Ozone Layer (Монреальский протокол по веществам разрушающим озоновый слой), соберутся в Кигали, Руанда, чтобы обсудить поправку к договору, согласно которому постепенно сократится, и в конечном итоге сойдет на нет использование гидрофторуглеродов (ГФУ). ГФУ являются одним из шести основных парниковых газов, которые обычно используются в кондиционерах и холодильных системах по всему миру.

Поправка была бы благом для устойчивого развития, и могла бы к 2050 году предотвратить выброс целых 100-200 миллиардов тонн эмиссий, вызывающих изменение климата. Этого было бы достаточно для того, чтобы мир прошел четверть пути к достижению 2º по Цельсию, цель установленная Парижским соглашением о глобальном потеплении, в декабре 2015 года.

Монреальский протокол был принят, чтобы восстановить озоновый слой, который защищает все живое на планете от смертельных уровней ультрафиолетовых лучей. До настоящего времени, это был значительный успех, с поэтапным отказом от почти 100 озоноразрушающих химических веществ, за последних три десятилетия. Озоновый слой заживает и, согласно последним оценкам, он мог бы восстановиться к 2065 году, сэкономив триллионы долларов глобальных расходов на здравоохранение и сельское хозяйство.

    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.
