Images of Change

Our planet is constantly changing, and we use the vantage point of space to increase our understanding of Earth, improve lives and safeguard our future. 

These images show change over time, with periods ranging from centuries to years. Some of these effects are related to climate change, some are not. Some document the effects of urbanization or the ravage of natural hazards such as fires and floods. All show our planet in a state of flux. Take a look…

Urban Expansion in New Delhi, India

Between the times these two images were taken, the population of India’s capital and its suburbs (known collectively as “Delhi”) ballooned from 9.4 million to 25 million. It is now second in population only to Tokyo, which has 38 million people.

Great Salt Lake Shrinkage, Utah

Dramatic change in the area of the Great Salt Lake over the past 25 years. The lake was filled to near capacity in 1985 because feeder streams were charged with snowmelt and heavy rainfall. In contrast, the 2010 image shows the lake shriveled by drought. The Promontory Peninsula (protruding into the lake from the top) is surrounded by water on three sides in the first image, but is landlocked on its eastern side in the second.

Exceptional Early Ice Melt, Greenland

Meltwater streams, rivers and lakes form in the surface of the Greenland Ice Sheet every spring or early summer, but melting began exceptionally early in 2016. Melting encourages further melting when pods of meltwater develop, since they darken the surface and absorb more sunlight than ice does. Surface melt contributes to sea-level rise when the water runs off into the ocean.

Iran’s Lake Urmia Changes Color

Some combination of algae and bacteria is periodically turning Iran’s Lake Urmia from green to red. The change typically occurs when summer heat and dryness evaporate water, increasing the lake’s saltiness. Data from satellites indicate that the lake has lost about 70% of its surface area over the last 14 years.

Owens Lake Degradation, California

Owens Lake lies in the Owens Valley between the Sierra Nevada and the Inyo Mountains, about 130 miles north of Los Angeles, California. For thousands of years, it was one of the most important stopover sites in the western U.S. for migrating waterfowl and shore birds. However, in the early 20th century, the lower Owens River, which fed the lake, was largely diverted to the Los Angeles aqueduct. Water from springs and artesian wells kept some of the lake alive, but toxic chemicals and dust impinged on the regional environment and disturbed the bird habitat.

Baban Rafi Deforestation, Niger

Baban Rafi Forest is the most significant area of woodland in the Maradi Department of Niger, a west African country on the southern edge of the Sahara Desert. These pictures show the loss of a significant fraction of the natural landscape (darker green areas) of the forest to agriculture. Population in this region quadrupled during the 40 years leading up to the 2007 image.

Colorado River Evolution, Mexico 

These two pictures illustrate the extremes of water flow in the Colorado River since measurements began in the late 1800s. The 1985 image was taken in the midst of record high flow, while the 2007 image shows the driest period. Excessive rains or severe droughts directly change the amount of water available in the Colorado River Basin, and so does the increasing pressure of human needs throughout the western states.

Helheim Glacier Melt, Greenland

Along the margin of the Greenland Ice Sheet, outlet glaciers flow as icy rivers through fjords and out to sea. These pictures show a fjord in which Helheim Glacier (on the left) is crumbling into large and small icebergs (light blue, on the right). The glacier outlet held steady from the 1970s until about 2001, then began to retreat toward its source about 4/7 miles between 2001 and 2005. The glacier’s flow to the sea has also sped up.

Drying Lake Poopó, Bolivia

Lake Poopó, Bolivia’s second-largest lake and an important fishing resource for local communities, has dried up once again because of a drought and diversion of water sources for mining and agriculture. The last time it dried was in 1994, after which it took several years for water to return and even longer for ecosystems to recover.

Flooding on the Ganges River, India

Heavy monsoon rains have caused catastrophic flooding along the Ganges and other rivers in eastern and central India. At least 300 people died and more than six million were affected by the flooding, according to news reports. These images show a stretch of the Ganges near Patna.

All of this knowledge about our home planet enables policy makers, government agencies and other stakeholders to make informed decisions on critical issues that occur all around the world. From rising sea levels to the changing availability of freshwater, we enable studies that unravel the complexities of our planet from the highest reaches of Earth’s atmosphere to its core.

Fluff + comedy, 2.5k words, namjoon/reader, potion shop au.

You’re sitting behind the counter, humming to yourself as you page through the yellowed parchment of your potions textbook. The potion shop is empty, giving you peace and quiet to study for your upcoming Magicks exam.

You wince at the door squealing open—you make a mental note to oil them later—and bookmark your page, standing up. The customer, a short, stocky lady dressed in unfamiliar garb, saunters in and lets the door creak shut behind her. She eyes the posters on the wall behind you that advertise the latest sales and list the best-selling potions of the shop.

“Is there anything I can help you with today?” You give her your sunniest smile.

“Yes,” she replies, curtly. “I want a custom potion.”

You try not to let her snappy, authoritative tone bother you. “Alright,” you say, with false brightness. You reach for your pen and notepad. “What will it be?”

“I’d like—“

Nearly everyone has been taught of the water cycle: how water evaporates into the air, condensates to form clouds, and precipitates as rain. Bronzong, it seems, is the master of the water cycle: it can summon rain clouds and bring about plentiful harvests. To understand how this pokémon works, we’re going to have to go more in depth than that.

At any given day, the air in the atmosphere is between 0 to 4% water vapor. In dry, cold environments there is less water. Warm, tropical, humid places tend to have more water in the atmosphere. For the water in the air to become clouds, several things need to happen.

First, the water needs to saturate. In other words, there needs to be more water in the atmosphere than the air can hold. How much water the air can hold is dependent on the pressure, humidity, and other conditions of the atmosphere, but an easy way to cause saturation is to lower the temperature. The cooler local air is, the less water it can hold. So by cooling the air to a certain temperature, called the dew point, the water will start to saturate, forming dews on leaves, or starts to form clouds by attaching to condensation nuclei.

Condensation nuclei are the “seeds” to clouds. Water will attach to these particles, typically specs of dust, dirt, or salt that floats in the air. “Artificial” clouds often use silver iodide, potassium iodide or dry ice for condensation nuclei. Water molecules attach to these nuclei, forming water droplets in the air. When sunlight hits a collection of these droplets, it scatters and appears white: a cloud.

As you can easily imagine, a condensation nuclei can only hold so much water before it becomes too heavy to float in the air, and starts to fall out of the sky. If the droplet gets large enough, by merging with other droplets for example, it will fall all the way to the ground as rain.

Now that we know how rain clouds form, we can figure out how Bronzong summons them. First, it needs to saturate the water in the air. It could do this by simply adding more water, but since Bronzong is not a water type this is probably not the case. Instead, Bronzong could lower the temperature of the air by absorbing heat from the atmosphere, similar to Gengar. Or, since it is a bell, Bronzong could ring. Sound is a pressure wave, so by manipulating the air pressure, Bronzong could promote saturation that way.

Now that the water starts to condensate, Bronzong fills the air with condensation nuclei, by kicking up clouds of dust, or perhaps producing chemicals itself, emitting puffs of silver iodide or similar chemicals for the water to attach to. 

Once the air is filled with floating air droplets, they just need to become heavy enough to fall. By ringing it’s bell, the sound causes vibrations in the atmosphere, causing the water droplets to run into each other and merge, eventually growing large enough to fall to the ground as rain.

Bronzong creates rain clouds by changing the pressure and temperature in the air, promoting water to condense. It then releases dust and chemicals into the air, which the water uses as seeds to attach to and form rain clouds.


Tired and over-worked, Glynda had decided to relax by indulging herself in some therapeutic dust chemistry. She had always been a rather gifted chemist, even a leading authority on a new branch of dust manipulation using aura. 

Which was what she was experimenting with currently. If she could utilize the energy from dust and convert it into a more compatible form perhaps dust could be used to recharge aura. The implication for huntsman and huntresses in the field would be tremendous. Ignoring the fact that she was tired and should probably rest she pressed on, mixing samples together with her telekinesis, the huntress levitated the final vile in front of herself and focused her semblance. 

She needed to stress the chemical bonds of the dust molecules and then reinforce them with her own aura. It went well at first, she thought, she could tell by the exothermic release that her application was correct.

Then something happened that she could not explain and she lost control of the reaction. In the next second an explosion rocked the entire lab. Groaning it took the huntress a second to pick herself up and take stalk of the damages. She herself seemed fine at least.

The modes range from the cartoonishly figurative to the augustly abstract, and the mediums from paint and pencil to toxic chemicals and meteorite dust. There is no Polke style, but only a distinctive force of talent and mind. With caustic humor and cultivated mystery, he could seem to hit a reset button from phase to phase, and even from piece to piece, and he regularly frustrated the efforts that curators, dealers, and critics made on his behalf, in ways that blurred his public image and hobbled his sales.
