TODAY’S MODERATOR: Time to flee Earth?


Here’s the most cheerful thing I’ve read this week, from Vox: “Theoretical physicist Stephen Hawking has set a deadline for humanity to save itself. Within the next 100 years, he warns, we need to colonize Mars and other planets. If we don’t, we may not survive climate change, disease, and other versions of doom we’re bound to inflict on ourselves this century.

“Hawking’s pessimistic take on humanity isn’t new. But the super-famous scientist and author has been making the case more urgently in advance of the release of his new BBC documentary,’ Expedition New Earth,’ this summer,” the website writes. Hawking says humanity needs to quickly slash the cost of space flight, find new ways to live on mostly inhospitable planets like Mars, and figure out faster ways to get there — or, we’re done for.

PERSPECTIVE: Hair? Heck, who needs it?

Meanwhile, Vox continues, “Timetables like Hawking’s are particularly troubling to climate scientists and others dedicated to fixing planet Earth right now. If we start looking for our salvation outside our solar system, we may be dissuaded and distracted from reducing greenhouse gas emissions to avert catastrophic climate change, they fear.”

Opinion: Remembering Barbara Bush, grieving mother

My mother and Barbara Bush were contemporaries. Despite coming from very different backgrounds — daughter of a Kansas farmer and daughter of a New York City businessman — they had a common experience, a very human link. It’s a sad connection that I suspect also has many a woman feeling fondly toward Bush, who died Tuesday at 92. Both...
Opinion: Paul Ryan is the ultimate party man

The mistake about Paul Ryan, the one that both friends and foes made over the years between his Obama-era ascent and his just-announced departure from the House speakership, was to imagine him as a potential protagonist for our politics, a lead actor in the drama of conservatism, a visionary or a villain poised to put his stamp upon the era. This Ryan-of-the-imagination...
Opinion: Foes of renewable energy increase risk of climate catastrophe

Peter Thiel, Facebook investor and Donald Trump supporter, is by all accounts a terrible person. He did, however, come up with one classic line about the disappointments of modern technology: “We wanted flying cars, instead we got 140 characters.” OK, now it’s 280, but who’s counting? The point of his quip was that while we&rsquo...

Opinion: What happened in Starbucks isn’t really about Starbucks

I don’t drink coffee, so I can’t boycott Starbucks. But I wouldn’t if I could. Yes, I understand — and share — the national anger over viral video of last week’s arrest of two African-American men at one of the company’s Philadelphia stores. The men, who have yet to be identified, were reportedly doing nothing...
