気になった一文集(English ver. No. 30)

Trump may have breathed life into the project, but its future remains uncertain. The drop in global oil prices has reduced the short-term profitability of the tar sands, and the long term is even murkier, given the global trend towards low-carbon energy.
トランプは(パイプライン敷設)計画に生命を吹き込むかもしれないが、その未来は不透明なままである。低炭素エネルギーに向けた世界的な動きの中で、世界的な石油価格の低下はタールサンドの短期的な利益率を減じているし、長期的な利益率となるとさらに暗雲が立ち込めている。

Renewable energies such as solar and wind are on the rise in the United States and abroad, and are now attracting more investment than fossil fuels. Coal’s US decline is likely to continue regardless of Trump’s promises, because the fuel is losing out to cheap natural gas, falling prices for renewables, and air-quality regulations that would be exceedingly hard to dismantle.
太陽光や風力といった再生かのエネルギーはアメリカ国内外で成長しつつあり、いまや化石燃料よりも多くの投資を引きつけている。石炭はより安価な天然ガスに負けており、再生可能エネルギーはより安価になりつつあり、廃止するのが極めて難しい空気の質に関する規制が存在するために、アメリカ国内で石炭使用が減少することはトランプ大統領の約束とは関係なしに続く見込みが高い。

The irony is that the United States was the lead proponent of the Paris framework, which is essentially a collection of voluntary pledges. As a result, it could be hard for the Trump administration to push its agenda onto other countries.
皮肉なことに、パリの気候枠組みを率いた提案国の一つがアメリカであり、パリ合意は根本的には自主的な約束の集まりにすぎない。結果として、トランプ政権がその政策を他国に押し付けることは叶わないだろう。

Later this year, the world's largest conservation area of any kind will come into force, protecting 1.55 million square kilometres of the Ross Sea in Antarctica. This means that nine of the ten largest protected areas on Earth will be marine. Still, the combined coverage of designated and implemented MPAs currently accounts for just 4% of total ocean area, compared with 15% on land.

They should take note of Gill and colleagues' study, because it provides a timely warning that rapid expansion of protected areas by itself will not provide desired outcomes if there are large shortfalls in our capacity to manage, monitor and finance those areas.

There is certainly no easy recipe for success, but global meta-analyses such as that of Gill et al. and others will help us to further constrain what is needed to heal the ocean, and to provide long-term benefits to people.
