The Great American Solar Eclipse of 2017: What, When, How?
Just yesterday at my local supermarket checkout line, I was innocently asked why I needed to pick up a pair of solar eclipse glasses. "Um, because I could go blind," I responded. "You should get a pair, too."
You see, I happen to live on the South Carolina coast, which is right on the path of totality and the last stop of the Great American Eclipse of 2017 (it's unofficial nickname). Many people are getting excited for this special event, and it's clear that some of you have pertinent questions. I'm here to help.
What's happening exactly?
On Monday, Aug. 21, the U.S. will be treated to a celestial spectacle. Those lucky enough to be on the "path of totality"—a 70-mile wide stretch that extends from Oregon to South Carolina—will get to see the sun's disk completely obscured by the moon (weather permitting, of course).
Observers will also get the rare opportunity to look directly at the solar corona, the radiant, outermost part of the sun's atmosphere. NASA says this is the first total eclipse to cross from coast-to-coast since 1918.

Does this mean it go dark?
If you are in an area with a high percentage of obscuration, yes, you will be in near darkness. But it only lasts a few minutes. Those not near the path of totality will see sunlight coming through.
Where and when will it happen?
Lincoln Beach, Oregon gets to see the eclipse begin around 9:05 a.m. PDT. It then crosses through Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia and North and South Carolina. It ends near Charleston, South Carolina at 2:48 p.m. EDT.

But I don't live on the path of totality. Can I still see it?
Very likely! Even if you're not on the path of totality, anyone living in North America can see at least a partial solar eclipse, where it will look like the moon took a chunk out of the sun. If you don't live in the U.S., the northern parts of South America and areas of Europe and Africa will also see a partial eclipse.
Do I really need solar eclipse glasses?
Yes. You could severely damage your eyes if you look directly at the sun. Regular sunglasses, binoculars and camera lenses will not do. You need a pair certified by the ISO 12312-2 international standard that have a special-purpose safe solar filter that blocks solar UV and infrared radiation. Due to reports of counterfeit glasses flooding the market, you'll want check on this Reputable Vendors of Solar Filters & Viewers page if your viewers comply.
Can I watch the eclipse if I don't have special glasses?
You can remove your glasses or look at the sun with the naked eye only when the sun is totally blocked by the moon.
Don't be tempted to look during any other point—even a tiny sliver of the crescent sun can burn your eyeballs. As Ralph Chou, professor emeritus at the School of Optometry & Vision Science at the University of Waterloo in Canada, told Space.com, "I have seen instances where the patient has eventually shown up with crescents burned into the back of the eye, and you can almost tell exactly when they looked."
If you can't get ahold of a pair of eclipse glasses, you can create simple pinhole projectors, a fun project for kids and adults alike. Also NASA will host a live stream which will play on NASA TV, YouTube and other TV stations.
Will traffic be bad?
It's likely. About 220 million Americans are within an hour's drive to states in the path of totality. Some cities are preparing for Superbowl-like conditions with expected congestion and travel delays.
Can I bring my dog to watch the eclipse?
Sure. Your dog, and your cat for that matter, instinctively know not to look directly at the sun and will probably ignore the event, animal experts say.
'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges $1 Trillion to Curb Climate Threat
By Julia Conley
Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged more than $1 trillion over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
‘Plastic Is Lethal’: Groundbreaking Report Reveals Health Risks at Every Stage in Plastics Life Cycle
With eight million metric tons of plastic entering the world's oceans every year, there is growing concern about the proliferation of plastics in the environment. Despite this, surprisingly little is known about the full impact of plastic pollution on human health.
But a first-of-its-kind study released Tuesday sets out to change that. The study, Plastic & Health: The Hidden Costs of a Plastic Planet, is especially groundbreaking because it looks at the health impacts of every stage in the life cycle of plastics, from the extraction of the fossil fuels that make them to their permanence in the environment. While previous studies have focused on particular products, manufacturing processes or moments in the creation and use of plastics, this study shows that plastics pose serious health risks at every stage in their production, use and disposal.
Air pollution within the home causes 3.8 million deaths a year, according to the World Health Organization. A recent University of Colorado in Boulder study reported by The Guardian found that cooking a full Thanksgiving meal could raise levels of particulate matter 2.5 in the house higher than the levels averaged in New Delhi, the world's sixth most polluted city.
