NASA time-lapse shows just how fast the Arctic sea ice is vanishing
Climate change is for real and it's increasingly looking like a problem that is already going to affect the current generation in a big way. The latest time-lapse from NASA showing just how fast the Arctic sea ice has vanished in the last three decades is a chilling reality check about the state of our planet!
It's not just that the ice is vanishing in the Arctic sea, the oldest and thickest ice has also continued to melt away, leaving the Arctic sea cap more vulnerable to the continued rise in temperature – both in our oceans and the atmosphere.
"Ice age is a good analog for ice thickness because basically, as ice gets older it gets thicker, This is due to the ice generally growing more in the winter than it melts in the summer." – Walt Meier, sea ice researcher at NASA's Goddard Space Flight Center
Arctic Sea Ice Is Vanishing
The time-lapse from NASA below, shows the annual change in the arctic sea ice age since January 1, 1984. It's chilling to see how much of the artic sea cap has vanished in the last three decades.

"What we've seen over the years is that the older ice is disappearing, This older, thicker ice is like the bulwark of sea ice: a warm summer will melt all the young, thin ice away but it can't completely get rid of the older ice. But this older ice is becoming weaker because there's less of it and the remaining old ice is more broken up and thinner, so that bulwark is not as good as it used to be." – Walt Meier, sea ice researcher at NASA's Goddard Space Flight Center.
The video below is a slightly longer version of the time-lapse with much more detailed explanations.

1 – DAVIS-MONTHAN AIR FORCE BASE AIRCRAFT BONEYARD
32.151087°, –110.826079°
The largest aircraft storage and preservation facility in the world is located at Davis-Monthan Air Force Base in Tucson, Arizona, USA. The boneyard – run by the 309th Aerospace Maintenance and Regeneration Group – contains more than 4,400 retired American military and government aircrafts.
2 – PORT OF ANTWERP
51.320417°, 4.327546°
The Port of Antwerp in Belgium is the second largest port in Europe, behind the Port of Rotterdam. Over the course of a year, the port handles more than 71,000 vessels and 314 million tonnes of cargo. That weight is roughly equal to 68% of the mass of all living humans on the planet.
3 – GEMASOLAR THERMOSOLAR PLANT
This Overview captures the Gemasolar Thermosolar Plant in Seville, Spain. The solar concentrator contains 2,650 heliostat mirrors that focus the sun's thermal energy to heat molten salt flowing through a 140-metre-tall (460-foot) central tower. The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity. In total, the facility displaces approximately 30,000 tonnes of carbon dioxide emissions every year.
4 – TULIPS
Every year, tulip fields in Lisse, Netherlands begin to bloom in March and are in peak bloom by late April. The Dutch produce a total of 4·3 billion tulip bulbs each year, of which 53% (2·3 billion) is grown into cut flowers. Of these, 1·3 billion are sold in the Netherlands as cut flowers and the remainder is exported: 630 million bulbs to Europe and 370 million elsewhere.
5 – OLIVES
Olive tree groves cover the hills of Córdoba, Spain. Approximately 90% of all harvested olives are turned into oil; the remaining 10% are eaten as table olives. With rising temperatures and phenomenal weather variations in growing regions, olive groves on high hills or slopes will probably suffer less, but groves located on low altitude areas or plains could become totally unproductive.
6 – MOAB POTASH EVAPORATION PONDS
Evaporation ponds are visible at the potash mine in Moab, Utah, USA. The mine produces muriate of potash, a potassium-containing salt that is a major component in fertilisers. The salt is pumped to the surface from underground brines and dried in massive solar ponds that vibrantly extend across the landscape. As the water evaporates over the course of 300 days, the salts crystallise out. The colours that are seen here occur because the water is dyed a deep blue, as darker water absorbs more sunlight and heat, thereby reducing the amount of time it takes for the water to evaporate and the potash to crystallise.
7 – ARLIT URANIUM MINE
The Arlit Uranium Mine is located in Arlit, Niger. French nuclear power generation, as well as the French nuclear weapons programme, are both dependent on the uranium that is extracted from the mine – more than 3,400 tonnes per year.
8 – QINHUANGDAO COAL TERMINAL
The coal terminal at the Port of Qinhuangdao in China is the largest coal shipping facility in the country. From here, approximately 210 million tonnes of coal are transported to coal-burning power plants throughout southern China every year. In 2015, new data from the Chinese government revealed that the country has been burning up to 17% more coal each year than previously disclosed. The sharp upward revision in official figures means that China has been burning an additional 600 million tonnes of coal each year, and has released much more carbon dioxide – almost a billion more tonnes per year – than previously estimated.
9 – MARABE AL DHAFRA
23.610424°, 53.702677°
The villas of Marabe Al Dhafra in Abu Dhabi, United Arab Emirates are home to approximately 2,000 people. Located in one of the hottest regions of the world, the record high temperature here is 49·2°C (120·6°F).
10 – LAKE OROVILLE HOUSEBOATS
Moored houseboats float peacefully on the New Bullards Bar Reservoir in Yuba County, California, USA. Due to a severe drought that has hit the state over the past four years, there is less space to anchor on the lake and many houseboats have been moved to a nearby onshore storage area.
11 – DELRAY BEACH, FLORIDA
Because many cities in the American state of Florida contain master-planned communities, often built on top of waterways in the latter half of the twentieth century, there are a number of intricate designs that are visible from the Overview perspective. One particular neighborhood in Delray Beach is seen here.
12 – DADAAB REFUGEE CAMP
–0.000434°, 40.364929°
Hagadera, seen here on the right, is the largest section of the Dadaab Refugee Camp in Northern Kenya and is home to 100,000 refugees. To cope with the growing number of displaced Somalis arriving at Dadaab, the UN has begun moving people into a new area called the LFO extension, seen here on the left. Dadaab is the largest refugee camp in the world with an estimated total population of 400,000.
13 – SUN LAKES
Sun Lakes, Arizona, USA is a planned community with a population of approximately 14,000 residents, most of whom are senior citizens. According to US census data, only 0·1% of the community's 6,683 households are home to children under the age of 18.
14 – DALLAS / FORT WORTH INTERNATIONAL AIRPORT
Dallas/Fort Worth International Airport stretches across 70 square kilometres (27 square miles) in Texas, USA. The facility is the tenth busiest airport in the world by passenger traffic, accommodating more than 64 million passengers each year.
15 – PORT OF SINGAPORE
1.237656°, 103.806422°
Cargo ships and tankers – some weighing up to 300,000 tonnes – wait outside the entry to the Port of Singapore. The facility is the world's second-busiest port in terms of total tonnage, shipping a fifth of the world's cargo containers and half of the world's annual supply of crude oil.
16 – JACKSONVILLE INTERCHANGE
A turbine interchange connects two highways in Jacksonville, Florida, USA. This structure consists of left-turning ramps sweeping around a centre interchange, thereby creating a spiral pattern of right-hand traffic.
17 – ANGKOR WAT
Angkor Wat, a temple complex in Cambodia, is the largest religious monument in the world (first it was Hindu, then Buddhist). Constructed in the twelfth century, the 820,000 square metre (8·8 million-square-foot) site features a moat and forest that harmoniously surround a massive temple at its centre.
18 – LA PLATA
The planned city of La Plata – the capital city of the Province of Buenos Aires, Argentina – is characterised by its strict, square grid pattern. At the 1889 World's Fair in Paris, the new city was awarded two gold medals in the categories 'City of the Future' and 'Better Performance Built'.
19 – EIXAMPLE
The Eixample District in Barcelona, Spain is characterised by its strict grid pattern and apartments with communal courtyards. This thoughtful and visionary design was the work of Ildefons Cerdà (1815–1876). His plan features broad streets that widen at octagonal intersections to create greater visibility with increased sunlight, better ventilation, and more space for short-term parking.
20 – IPANEMA BEACH
Ipanema Beach is located in the South Zone of Rio de Janeiro, Brazil. Recognised as one of the most beautiful beaches in the world, the sand is divided into segments by lifeguard towers known as 'postos'.
21 – BURNING MAN
Burning Man is a week-long, annual event held in the Black Rock Desert of Nevada, USA. Drawing more than 65,000 participants each year, the event is described as an experiment in community, art, self-expression, and radical self-reliance.
22 – CENTRAL PARK
Central Park in New York City, USA spans 341 hectares (843 acres), which is 6% of the island of Manhattan. One of the most influential innovations in the park's design was its 'separate circulation systems' for pedestrians, cyclists, horse riders, and cars. The park contains numerous tennis courts and baseball fields, an ice-skating rink, and a swimming pool. It also serves as the finish line for the New York City Marathon and New York City Triathlon.
23 – IRON ORE MINE TAILINGS POND
Tailings are the waste and by-products generated by mining operations. The tailings seen here were pumped into the Gribbens Basin, next to the Empire and Tilden Iron Ore Mines in Negaunee, Michigan, USA. Once the materials are pumped into the pond, they are mixed with water to create a sloppy form of mud known as slurry. The slurry is then pumped through magnetic separation chambers to extract usable ore and increase the mine's total output. For a sense of scale, this Overview shows approximately 2.5 square kilometres (1 square mile) of the basin.
24 – SOUTHERN CALIFORNIA LOGISTICS AIRPORT GRAVEYARD
The Southern California Logistics Airport in Victorville, California, USA contains an aircraft boneyard with more than 150 retired planes. Because the demand for jumbo jets has dropped significantly in the last two decades in favour of smaller, more affordable twin-engine planes, many large aircrafts such as Boeing 747s and Airbus A380s have been retired. The dry conditions in Victorville – located on the edge of the Mojave Desert – limits the corrosion of metal, meaning planes can be stored here for years while they are stripped for spare parts.
25 – NISHINOSHIMA VOLCANIC ACTIVITY
27.243362, 140.874420
Nishinoshima is a volcanic island located 940 kilometres (584 miles) south of Tokyo, Japan. Starting in November 2013, the volcano began to erupt and continued to do so until August 2015. Over the course of the eruption, the area of the island grew in size from 0.06 square kilometres (0.02 square miles) to 2·3 square kilometres (0·89 square miles).
26 – THE EMPTY QUARTER
Rub' al Khali, or The Empty Quarter, is the largest sand desert in the world. It covers 650,000 square kilometres (251,000 square miles), and includes parts of Saudi Arabia, Oman, Yemen, and the United Arab Emirates. In the centre of the desert there are a number of raised, hardened formations that were once the sites of shallow lakes, thousands of years ago. For a sense of scale, this Overview shows approximately 350 square kilometres (135 square miles) in Saudi Arabia, near the border with Oman.
27 – SHADEGAN LAGOON
Dendritic drainage systems are seen around the Shadegan Lagoon by Musa Bay in Iran. The word 'dendritic' refers to the pools' resemblance to the branches of a tree, and this pattern develops when streams move across relatively flat and uniform rocks, or over a surface that resists erosion.
