These Haunting Images From Space Show Climate Change Up Close

Through the Landsat program, a series of satellites it launched into space to to take images of our increasingly transforming planet.

In 1984 Madonna ruled the airwaves, Apple's Macintosh personal computer went on sale, Iran accused Iraq of using chemical weapons, and The Chicago White Sox defeated the Milwaukee Brewers 7-6 in the longest game in Major League Baseball history. That's what happened on a micro level. In 1984, however, the Earth, as always, was changing, shifting, growing, and shrinking. That's the year when NASA had the foresight to capture it all, through the Landsat program, a series of satellites it launched into space to take images of our transforming planet.

Two generations, eight satellites and millions of pictures later, NASA, in collaboration with the U.S. Geological Survey, have compiled a remarkable catalog of their visual findings that show how our planet has evolved on a macro level. Partnering with Google, they've released these images to the public both as stills and videos that show the world through time lapsed footage.

While a picture tells a thousand words, the quality of the Landsat pictures are worth even more. The type of high-definition images we see daily use 2 million pixels per frame, whereas the Landsat images are 1.8 trillion pixels—high definition to the most extreme degree. They were taken over the course of 41 years, with each satellite orbiting the Earth every 84.3 minutes, revisiting the same part of the planet on average once every 16 days.



The images reveal a paradox. On the one hand they tell the story of man and great civilizations: we build up, around, and out (we watch Dubai create entirely new towns into the ocean); yet we destroy the very land we want to live upon. You can literally watch the Amazon rainforest disappear, glaciers retreat, Lake Mead in Las Vegas shrink, mountaintops are decapitated by mining companies, and loggers carve into forests. The shots are at once beautiful and disturbing. The takeaway is that we now have a tool to see up close just how devastating the effects of climate change are. And with that information, hopefully it will encourage us all to be stewards of change whether in our own backyards—on the micro level—or on a larger, macro level.

Anyone who has ever worked in retail knows that the worst thing about the job, right after the pay, are the unreasonable cheapskates who "want to talk to your manager" to get some money off an item.

They think that throwing a tantrum will save them a few bucks and don't care if they completely embarrass themselves in the process. Sometimes that involves belittling the poor employee who's just trying to get through their day with an ounce of dignity.

Twitter is rallying around a gal named Tori who works at a Target in Massachusetts after she was tweet-shamed by irate chapekate, journalist, and Twitter troll, David Leavitt.

Childbirth is the number one reason American women visit the hospital, and it ain't cheap. In fact, it's getting more and more expensive. A new study published in Health Affairs found that the cost of having a baby with employer-sponsored health insurance increased by almost 50% in the past seven years.

The study evaluated "trends in cost-sharing for maternity care for women with employer-based health insurance plans, before and after the Affordable Care Act," which was signed into law in 2010. The study looked at over 657,061 women enrolled in large employer-sponsored health insurance plans who delivered babies between 2008 and 2015, as these plans tend to cover more than plans purchased by small businesses or individuals.

A meteorite crashed into Earth nearly 800,000 years ago. The meteor was 1.2 miles wide, and the impact was so big, it covered 10% of the planet with debris. However, scientists haven't been able to find the impact site for over a century. That is, until now. A study published in the Proceedings of the National Academy of Sciences journal believes the crash site has been located.

Tektites, which are essentially rocks that have been liquefied from the heat of the impact and then cooled to form glass, help scientists spot the original impact site of a meteor. Upon impact, melted material is thrown into the atmosphere, then falls back to the ground. Even if the original crater has disappeared due to erosion or is hidden by a shift in tectonic plates, tektites give the spot away. Tektites between 750,000 to 35.5 million years old have been found in every continent except Antarctica.
