Quartz: Scientists have developed a new plastic that can be recycled infinitely

But now chemists at Colorado State University have made a new kind of plastic that can be recycled over and over again without losing its quality. The plastic, reported in the journal Science, can be broken down into its building blocks using mild temperatures and chemicals, and then built back up again to be as good as new.

The world produces around 300 million tons a year, and this is expected to exceed 500 million tons by 2050. Most plastics are produced for a single use. Only 5–10% of plastics are recycled today. And the resulting plastic is of low quality so it isn’t recycled again and also ends up in landfills. Biodegradable plastics and novel ways to break down plastic help. [...]

Eugene Chen and his colleagues have found a way to do that. They have developed a plastic that can be produced from a ring-shaped molecule in just a few minutes at room temperature and without the need for harsh solvents. The plastic is as strong as commercial plastics.

Quartz: Hawaii pledges to become carbon neutral by 2045—the most ambitious goal of any US state

One of the bills cites a study that found that Hawaii could suffer $19 billion worth of damage to private property because of a rise in sea levels. When public infrastructure is included, the damage will likely be a lot higher. That is why it isn’t surprising that the US state most vulnerable to climate change is the one most keen to mitigate its impact. [...]

To be sure, it’s not clear if the state has thought through how hard a net-zero emissions target is to meet. The bill mentions initiatives such as planting trees and improving soil health as means of sequestering carbon, but not technologies such as carbon capture and storage that are proven to reduce emissions on a larger scale. That’s where the greenhouse-gas sequestration task force will help. It has a 2023 deadline to craft a plan that Hawaii can use to reach carbon neutrality. One of the bills also opens the door for the state to participate in carbon-trading programs, such as the one in California, and to use other market-driven tools to cut emissions.

Before Hawaii’s latest moves, Rhode Island was the state with the most ambitious climate goal: cutting emissions by 85% of 1990 levels by 2050. More importantly, Hawaii can now count itself among the most climate-friendly territories in the world. The Maldives aims to become carbon neutral by 2020, Costa Rica by 2021, Norway by 2030, Iceland by 2040, Sweden by 2045, and New Zealand by 2050. The UN’s Intergovernmental Panel on Climate Change has made it clear that more states and countries will need to join this list if the world as a whole is to avoid climate catastrophe.

The Washington Post: 5 big consequences of Trump’s Iran blunder

Ranking member of the Foreign Relations Committee Sen. Robert Menendez (D-N.J.) said in a written statement, “While I strongly opposed the JCPOA, it is a grave mistake to walk away from this deal without a plan for ensuring that Iran does not restart its nuclear weapon program, without a strategy for countering Iran’s dangerous non-nuclear activities, and without our allies and partners.” He added, “The governments of Iran, Russia, and China will seize this opportunity of self-imposed U.S. isolation to continue major weapons sales, deepen economic ties, and further challenge the United States and Europe not only in the Middle East but in other areas like North Korea.”  [...]

Second, whether our allies will now cooperate with this on nonnuclear matters including sanctions for Iran’s ballistic missile program and its support for terrorism is an open question. The European Union has every reason to be wary of U.S. promises. In making it harder to deal with issues that were outside of the JCPOA, Trump makes our overall policy to Iran weaker and less coherent. 

Third, the administration’s total inability to plan ahead is on full display. Will we exempt allies from newly imposed sanctions? Do we have a military plan if Iran does make a race for the bomb — and if so, will allies join with us after we have backed out of the deal? How will we enforce sanctions? The plethora of questions belie anti-JCPOA hawks’ assurances that the administration had figured out all the post-deal angles. Hardly. The Treasury Department advises, “Sanctions will be reimposed subject to certain 90 day and 180 day wind-down periods. At the conclusion of the wind-down periods, the applicable sanctions will come back into full effect.” It’s unclear if Trump and his negotiators intend to use this time to extract more concessions from our allies. For now, we lack a clear path forward.

CNN: Donald Trump just accidentally revealed something very important about his 'fake news' attacks

Trump either doesn't understand or ignores the difference between a story he doesn't like and one that is not true. He conflates the two for his own political purposes -- knowing his base hates the media and is more than ready to believe that journalists are willing to make up stories just to make Trump look bad. [...]

Here's the problem: Trump's attacks on the media -- as flawed and dishonest as they are -- are working. More than 4 in 10 people in a Gallup poll earlier this year could not name a single objective news source. Almost eight in 10 (77%) in a Monmouth University poll released last month said TV and print media report "fake news." That's a 14-point bump from the number of people who said the same last year. [...]

But, it's also important for people to understand what's behind Trump's aggressive anti-media campaign. Trump is about Trump. He calls media "fake news" because the coverage of him isn't as positive as he would like.

The Atlantic: America's Iraq War Amnesia May Doom the Iran Deal

The parallels between that moment and this one are uncanny. In both cases, American leaders feared that a longtime Middle Eastern adversary was breaking free of the fetters that had previously restrained it. In both cases, American leaders pursued a more confrontational policy, which they buttressed with frightening statements about the regime’s nuclear program. In both cases, international inspectors contradicted those alarmist claims. In both cases, America’s European allies defended the inspectors and warned of the chaos America’s confrontational policy might bring. In both cases, hawks in America and Israel responded by trying to discredit the inspection regime. And in both cases, two leaders of that effort were John Bolton and Benjamin Netanyahu. [...]

Their argument begins, once again, with the claim that a fearsome adversary is breaking free of the constraints that previously held it in check. In the run-up to the Iraq War, Bolton warned that because of weakening international sanctions and a feckless Clinton administration, Saddam “represents a serious and growing security threat.” Earlier this month, Netanyahu’s Ambassador to the United States, Ron Dermer, declared that, “as all the sanctions were removed, as all the money has flowed into Iran” because of the nuclear deal, “now you see Iran marching through the Middle East.” Bolton last year claimed that, “Tehran is trying to cement an arc of control from its own territory, through Baghdad-controlled Iraq and Mr. Assad’s Syria, to Hezbollah-dominated Lebanon.” The irony, which neither Netanyahu nor Bolton acknowledge, is that Iran’s growing regional strength stems in large measure from the Iraq War they championed, which turned Iraq from a bulwark against Iranian power into a close Iranian ally. [...]

There’s no single answer. Part of the explanation is partisanship. Politics is today such a team sport that people often downplay or overlook even the grossest offenses by their own side. More than 60 percent of Republicans, according to a March Pew Research Poll, think the United States was right to invade Iraq. George W. Bush’s approval rating among Republicans, according to a January CNN poll, is 76 percent. I suspect that those numbers reflect tribal loyalty more than any considered judgment about the war’s impact. But they make it easy for Republican officials to claim, as Bolton does, that the real mistake wasn’t Bush’s decision to send troops to Iraq but Obama’s decision to withdraw them. Since many Republicans won’t even admit the Iraq war was wrong, it’s hard to apply its lessons to the current debate over Iran. It’s particularly hard since doing so would mean admitting not only that Bush was wrong in waging war with Iraq but that Obama was right in striking a deal with Iran. When was the last time you heard Trump admit that Obama was right about anything? [...]

The third reason for America’s inability to apply the lessons of Iraq to the current debate over Iran is the media, especially television. It’s rare to see non-Americans on political talk shows. That matters because non-Americans overwhelmingly think pulling out of the Iran deal is nuts. And non-Americans are more likely to raise fundamental questions about American nuclear policy—like why America isn’t pushing for inspections of Israel’s nuclear program, and why America keeps demanding that other nations denuclearize while building ever more nuclear weapons of its own. A more international foreign policy debate would help Americans to see how insular, self-interested, and hypocritical Bolton and Netanyahu’s views actually are. It might also expose Americans to some of the experts who understand nuclear inspections best. When was the last time you saw Mohamed ElBaradei, Hans Blix, or Yukio Amano on cable?
