Satellite Data Of Melting Arctic Essay

650 words - 3 pages

The Arctic Circle is melting at the rate of twice as fast as the global rate due to global warming. The effect of the Arctic Circle warming faster than the rest of the world is that it raises sea level substantially. The projections for the future show a two to three times higher warming rate than for the rest of the world. The picture on the next page shows the difference in the melting of ice from the year 1979 to 2003. Over nine percent shrunk in those twenty-four years. The data from the picture was collected by several satellites and there pictures put together and formed into a rendered picture. The data used to create these images come from a variety of different instruments flying on a group of satellites; they include the scanning multi-channel microwave radiometer attached to the Nimbus 7 satellite, and the special sensor microwave imagers attached to the Defense Meteorological Satellite Program's F8, F11, and F13 satellites.The data shows a continues effect on the melting of the Artic Circle. Soon there will be no circle any more. Less ice means more open water therefore, more open water means greater absorption of energy from the sun. More absorption of energy from the sun means increased rates of warming in the ocean which then goes back around the loop to melting ice but at a faster rate. The picture also show that the rate of warming in the Arctic over the last twenty years is eight times the rate of warming over the last one-hundred years! Arctic summer sea ice reached the lowest level in the satellite record in 2003 and the sea ice melt season has increased by 10 to 17 days per decade. Soon there will be no ice season.This data collected from the NASA foundation could give biologists the opportunity to show the world what us humans are doing to the environment and the animals in it. Biologists could explain accurately what the effect of the melting could do...

How Is the Climate Influencing the Polar Ice Caps and How Has the Change with Polar Ice Caps Influenced the Global Climate?

1110 words - 5 pages bodies. It is a two way process and the causes are mostly anthropogenic. Recent studies based on satellite monitoring by NASA reveals that melting ice from both the poles has been responsible for a fifth of the global rising sea levels since 1992 (11 mm). Antarctica and Greenland are now contributing three times as much ice to sea levels as they were 20 years ago. Although the Greenland ice sheet is only about one tenth the size of Antarctica

Some species in the region, such as Butterflyfish, Damselfish, and two Wrasses are now assumed to be locally extinct as well as six other special sustaining critically low populations. Sea levels aren’t the only part of nature affected by melting glaciers and ice. Polar bears among other indigenous cultures in the arctic environment also suffer from the loss of sea-ice. More than a million species could potentially face

A Heated Debate On ThePolar Vortex

633 words - 3 pages great debate; are the arctic storms at lower latitudes normal weather patterns? Or are they happening due to human activity? The effects of climate change are reshaping weather patterns all over the globe, and with sea ice melting more rapidly than ever before in history, strange weather events will continue to effect human, animal and plant life. Carbon dioxide and methane are gases that have existed in the atmosphere since the earth was in

Polar Ice Essay

869 words - 4 pages ice sheets hold a large portion of Earth’s fresh water and if they were to melt it would cause the sea level to rise. Scientists here have found something a little different.

This trend has proven to be consistent over the short and long term studies (Dahl-Jensen, 2000). Other research has been done
