Setiment in Louisiana
NASA satellites continually monitor the Earth, snapping photos and sending information to researchers on the ground.
Most of the time, things seem to be more or less the same as they were the day before, but the Earth is actually constantly changing. Sometimes it changes through discrete events, like landslides and floods. Other times, long-term trends, such as climate change, slowly reshape the land in ways that are difficult to see.
By zooming way out, we can get a new perspective of the events that have changed the Earth. These 10 before-and-after photos show the disasters, trends, and changes that have affected our planet, as seen from space.
1. In May 2016, NASA's satellites picked up the devastating 2016 Fort McMurray wildfire.

In May 2016, a wildfire broke out near Fort McMurray in Alberta, Canada. It destroyed more than 2,400 homes and businesses and burned through roughly 1,500,000 acres of land before it was under control. (Some of the pictures use false-color imaging to distinguish between land types, by the way).
2. The satellites also captured how landscapes eventually recover from fires, like in Yellowstone.

In 1988, wildfires burned through over a third of Yellowstone National Park. 28 years later, images show that much of the forest and plains have returned.
3. They saw drought shrink Utah's Great Salt Lake over the last 30 years ...

Water supplies have shrunk with a possible link to climate change.

Persistent drought has shrunk water supplies throughout much of the West. Scientists now think this may be linked to climate change.
4. And they showed the Mississippi pouring over its banks in March 2016.

Record-breaking rain inundated much of the Mississippi Delta in the spring of 2016, causing the mighty river to spill over its banks.
5. In West Virginia, surface mining reshaped mountaintops.

Mountaintop mining is often used to search for coal and can have lasting effects on the land.
6. In Washington state, the Oso mudslide changed the Earth back in 2014.
Before:
Mudslides can create significant change to an environment.
All images from NASA.
After:
A landslide reshapes a community and kills 43 people in Washington state.

43 people were killed in the March 2014 landslide in western Washington.
7. In Louisiana, sediment carried by water created new land.
Before:
Water carries sediment which changes the topography.

After:
Sediment can create new land.
All images from NASA.
Rivers and streams often carry sediment with them. As they slow down and reach the coast, that sediment falls out of the water. Over time, this can create new land, as you can see above.
8. The images show Hurricane Isaac touching down in Louisiana.
Before:
Satellite image before the hurricane.
All images from NASA.
After:
Image of the flooding of Louisiana after the hurricane.
All images from NASA.
Hurricane Isaac hit the gulf coast in August 2012. 41 people lost their lives and more than $2 billion worth of damage occurred. Above you can see the flooding that still lingered afterward.
9. And warming temperatures shrink Alaska's Columbia Glacier.
Before:

After:
Warmer global temperatures have shrunk many glaciers.
All images from NASA.
Over the last 28 years, warmer global temperatures have shrunk many glaciers, including Alaska's Columbia Glacier. From above, the shrinkage is crystal clear.
10. Meanwhile, our cities grew and expanded, like this image of San Antonio, Texas, shows.
Before:

All images from NASA.
After:
The city has started to take up more space than the natural environment.
All images from NASA.
San Antonio — home of the Alamo and the Spurs basketball team — had a population of just over 1 million people in 1991. Today, it's added another 400,000 people.
The above images are only a small set of the many pictures NASA released. Globally, there were a ton of other interesting sites, like entire lakes turning red in Iran, new islands being formed by ocean volcanoes, and dams flooding rainforests in Brazil.
The world — and our country — is constantly changing, and we play a part in that.
Sometimes nature changes us, such as people having to respond to floodwaters, but we also know humans affect the Earth as well. And while it's true that the Earth has gone through natural cycles, we know it's now happening faster than ever before.
As the Earth will continue to change, it's important to remain aware of how we affect the Earth — and how the Earth affects us.

Thank goodness this story has a happy ending.
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
