Tahun Pemulihan Laut

OXFORD – Keutamaan laut di dunia tidak dapat dikesampingkan. Laut menyediakan 50% oksigen yang kita hirup, pangan bagi miliaran orang, dan penghidupan bagi jutaan penduduk lainnya. Laut berfungsi sebagai ‘pompa biologis’ yang penting dalam menjaga stabilitas atmosfer dan distribusi panas. Selain itu laut memegang peranan vital dalam mitigasi dampak perubahan iklim. Singkatnya, laut ibarat sekutu terdekat dan kita harus mengerahkan segala daya upaya untuk melindunginya.

Upaya ini semakin diperlukan, mengingat berbagai ancaman yang tidak terduga dan belum pernah terjadi sebelumnya yang tengah kita hadapi. Meskipun laut merupakan faktor penting dalam memperlambat perubahan iklim, menyerap lebih dari 30% emisi gas rumah kaca dan 90% kelebihan panas yang dihasilkan sejak Revolusi Industri, kerugian yang dialami sangat besar. Pengasaman laut dan pemanasan terjadi pada laju yang mengkhawatirkan dan sudah berdampak buruk pada ekosistem laut yang paling berharga – dampak negatif yang akan meluas.

Kini, banyak negara mengalami fenomena yang kemungkinan adalah peristiwa El Niño terkuat dalam sejarah. Cuaca buruk akibat fenomena ini – berasal dari Pasifik tapi mempengaruhi seluruh perairan dunia – diperkirakan mempengaruhi lebih dari 60 juta penduduk tahun ini dan memperparah penderitaan yang terjadi tahun lalu. Keadaan ini menjadi pengingat serius atas kerentanan kita terhadap guncangan, baik itu alami dan dipicu manusia (human-induced) pada sistem bumi.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
