This glacier was featured on a postcard in 1900. A camera captured where it is today.

Whoa.

This glacier was featured on a postcard in 1900. A camera captured where it is today.




116 years ago, the Pasterze glacier in the Austria's Eastern Alps was postcard perfect:

Snowy peaks. Windswept valleys. Ruddy-cheeked mountain children in lederhosen playing "Edelweiss" on the flugelhorn.

But a lot has changed since 1900.

Much of it has changed for the better! We've eradicated smallpox, Hitler is dead, and the song "Billie Jean" exists now.

On the downside, the Earth has gotten a lot hotter. A lot hotter.

The 15 warmest years on record have all occurred since 1998. July 2016 was the planet's hottest month — ever.

Unsurprisingly, man-made climate change has wreaked havoc on the planet's glaciers — including the Pasterze, which is Austria's largest.

Just how much havoc are we talking about? Well...


A series of stunning photos, published in August, show just how far the glacier has receded since its heyday.

First measured in 1851, the glacier lost half of its mass between that year and 2008.

A marker placed in 1985 shows where the edge of the glacier reached just 31 years ago. You can still see the ice sheet, but just barely, way off in the distance. In between is ... a big, muddy lake.

The view from the glacial foot marker from 1995 — 10 years later — isn't much more encouraging.

Even in just one year, 2015, the glacier lost an astounding amount of mass — 177 feet, by some estimates.

Ice continues to melt daily, and while the dripping makes for a good photo, it's unfortunate news for planet Earth. Glacial melting is one of the three primary causes of sea-level rise.

According to a European Environment Agency report, the average temperature in the Alps has increased 2 degrees Celsius in the last 100 years — double the global average.

Beautiful, but ominous, fissures in the glacier.

It's not unreasonable to assume that that's why this mountain hut has been abandoned by the flugelhorn-playing children who once probably lived in it.

Is there anything we can do to stop climate change besides look at scary glacier photos?

Climate change is, unfortunately, still a robust debate in the United States as many of our elected officials refuse to acknowledge that we humans are the ones doing the changing. As of last year, that list included a whopping 49 senators. Calling them to gently persuade them otherwise would be helpful. Not voting for them if they don't change their minds would be even more so.

There is some tentative good news — the Paris Agreement signed in December 2015 commits 197 countries, including the U.S., to take steps to limit future global temperature rise to 2 degrees Celsius. While it may be too late for the Pasterze glacier, if we really commit as a world, we might be able to stop ourselves from sinking whole countries and turning Miami into a swimming pool and stuff like that.

And who knows, with a little luck, and a little more not poisoning the sky, we just might recapture a little of that Alpine magic one day.

OK, these guys are Swiss. But who's counting?

Optical illusions are wild. The way our brains perceive what our eyes see can be way off base, even when we're sure about what we're seeing.

Plenty of famous optical illusions have been created purposefully, from the Ames window that appears to be moving back and forth when it's actually rotating 360 degrees to the spiral image that makes Van Gogh's "Starry Night" look like it's moving.

But sometimes optical illusions happen by accident. Those ones are even more fun because we know they aren't a result of someone trying to trick our brains. Our brains do the tricking all by themselves.

This Map Reveals The True Value Of $100 In Each State

Your purchasing power can swing by 30% from state to state.

Image by Tax Foundation.

Map represents the value of 100 dollars.

As the cost of living in large cities continues to rise, more and more people are realizing that the value of a dollar in the United States is a very relative concept. For decades, cost of living indices have sought to address and benchmark the inconsistencies in what money will buy, but they are often so specific as to prevent a holistic picture or the ability to "browse" the data based on geographic location.

The Tax Foundation addressed many of these shortcomings using the most recent (2015) Bureau of Economic Analysis data to provide a familiar map of the United States overlaid with the relative value of what $100 is "worth" in each state. Granted, going state-by-state still introduces a fair amount of "smoothing" into the process — $100 will go farther in Los Angeles than in Fresno, for instance — but it does provide insight into where the value lies.

The Story of Bottled Waterwww.youtube.com

Here are six facts from the video above by The Story of Stuff Project that I'll definitely remember next time I'm tempted to buy bottled water.

1. Bottled water is more expensive than tap water (and not just a little).

via The Story of Stuff Project/YouTube


A Business Insider column noted that two-thirds of the bottled water sold in the United States is in individual 16.9-ounce bottles, which comes out to roughly $7.50 per gallon. That's about 2,000 times higher than the cost of a gallon of tap water.

And in an article in 20 Something Finance, G.E. Miller investigated the cost of bottled versus tap water for himself. He found that he could fill 4,787 20-ounce bottles with tap water for only $2.10! So if he paid $1 for a bottled water, he'd be paying 2,279 times the cost of tap.

2. Bottled water could potentially be of lower quality than tap water.

A 6-year-old asks ​Neil DeGrasse Tyson an adorable question. He gives her an awesome answer.

"The most beautiful thing we can experience is the mysterious. It is the source of all true art and science." — Albert Einstein

Neil DeGrasse Tyson at College of the Holy Cross in Worcester, MA.

I recently spent some time with Dr. Neil deGrasse Tyson. He's known not only for breaking down stereotypes about what kinds of people go into science, but he has actively stood up and spoken against those who would close its doors, especially to young women.

So when Neil was asked this question by a little girl during a public speech, he gave one of the best answers I've ever heard. It may drive some parents crazy, but it also might just help change the world.

Kara Coley, a bartender at Sipps in Gulfport, Mississippi, got an unusual phone call on the job last week.

"Good evening," Coley answered. "Thank you for calling Sipps!"

A woman on the other end of the line asked, "Is this a gay bar?"

Sipps welcomes everyone, Coley explained to her, but indeed attracts a mostly LGBTQ crowd.

An avocado tree farmer explains the science of Hass avocados

Have you ever seen anyone put an avocado pit in water to grow an avocado tree? I've seen lots of people try, but only a few succeed. My mom has a tiny avocado tree growing in her living room that she managed to grow from the pit of a Hass avocado she ate. It's small but thriving, and I've often wondered if it will ever grow actual avocados.

As it turns out, it could—but they won't be Hass avocados.

Wait, huh?
