Will we run out of freshwater?
While our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world's freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.
What percent of Earth's water is drinkable?
0.5% of the earth's water is available fresh water. If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon). In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.

How much of the world is covered by water?
About 71% of the planet is covered by water while the rest is land. Water is considered a finite source; it circulates across the oceans, land surface and underground. The bottled water we drink was once flowing in the rivers and existed in the atmosphere as water vapor before cooling a trickling down as rain.
How did water come to Earth?
Researchers theorize water reached the planet from water-rich icy comets, meteoroids and trans-Neptunian objects. It was first thought that the water arrived after the earth formed but recent research by the Woods Hole Oceanographic Institution have shown that water was part of the earth’s formation process. Earth’s sister, planet Mars, has exhibited signs that rivers and lakes once traversed it. The planet’s thin atmosphere is thought to have been unable to hold on to the water. Further study of the planet has revealed that the planet has frozen water below the surface of its polar region. In 2008-2009 researchers analyzed parts of the moon’s surface, and the samples collected from the Apollo missions and revealed that the moon’s surface is wetter than previously thought.

How many glaciers are there in Glacier National Park?from epa.gov
Visitors from far and wide are drawn to Glacier National Park in Montana for its dramatic beauty and its glaciers. The total surface area of the 37 named glaciers in Glacier National Park decreased by about 34 percent between 1966 and 2015. Every glacier was smaller in 2015 than in 1966.
How to make water freeze?from thoughtco.com
You can supercool water—cool it below its stated freezing point—so it will crystallize into ice on demand. Place an unopened bottle of distilled or purified water in the freezer and chill it for 2.5 hours, then remove it from the freezer. You can make the water freeze instantly if you shake the bottle or open it and quickly pour the water onto a piece of ice. If you try the second method, the water often will freeze backward from the ice cube into the bottle.
What is Snow?from thoughtco.com
Snow is precipitation in the form of ice crystals. It originates in clouds when temperatures are below the freezing point (0 degrees Celsius, or 32 degrees Fahrenheit), when water vapor in the atmosphere condenses directly into ice without going through the liquid stage. Once an ice crystal has formed, it absorbs and freezes additional water vapor from the surrounding air, growing into a snow crystal or snow pellet, which then falls to Earth.
How does ice affect the Arctic?from epa.gov
For communities in Arctic regions, reduced sea ice could increase coastal erosion and exposure to storms, threatening homes and property, while thawing ground could damage roads and buildings and accelerate erosion. Conversely, reduced snow and ice could present commercial opportunities for others, including ice-free shipping lanes ...
Why does snow cover and ice make the Earth's surface warmer?from epa.gov
Because of their light color, snow and ice also reflect more sunlight than open water or bare ground, so a reduction in snow cover and ice causes the Earth’s surface to absorb more energy from the sun and become warmer.
How does ice affect climate?from epa.gov
Such changing climate conditions can have worldwide implications because snow and ice influence air temperatures, sea level, ocean currents, and storm patterns.
What is the permafrost in Alaska?from epa.gov
Permafrost. About 80 percent of Alaska's land is underlain by permafrost, which refers to rock or soil with ice that stays frozen for two or more years. Between 1978 and 2020, permafrost temperatures increased at 14 out of 15 long-term monitoring sites in Alaska. Permafrost has warmed most quickly in northern Alaska. These increases in permafrost temperatures are driven mostly by long-term air temperatures and are consistent with changes observed in other parts of the Arctic.
