What is the importance of albedo?
The albedo effect reflects the sun's radiation helping to slow the effects of global warming (like sea ice, white ice caps and glaciers). If (or when) these melt, then the reflection will stop and the warming will speed up!
Does ice reflect sunlight like a mirror?
Sea ice has an albedo of between 0.5 and 0.7. This means that it reflects between 50 and 70% of the sun's radiation (that lands on the ice).Ice with snow on it has a higher albedo, between 70 and 90%.Of the 100% of the sun's radiation that reaches the earth, 4% is reflected by the earth's surface, with about 2% reflected by ice.
How does a low albedo affect the earth?
A low albedo means that a surface absorbs more sunlight and heat, leading to warming. This can contribute to climate change by increasing temperatures and melting ice caps, which in turn can lead to rising sea levels and changes in ecosystems.
Is the sea level higher or lower than it was in the geologic past?
Sea levels have fluctuated throughout geologic history, sometimes being higher and sometimes lower than they are today. During periods of glacial melting, sea levels were higher, while during ice ages, sea levels were lower due to water being locked up in ice sheets. Currently, sea levels are rising due to global warming and melting ice caps.
What might be the effect of sprinkling black soot over the ice in the Arctic and Antarctica?
This would alter the snow-albedo feedback. Darkening the surface of snow/ice greatly lowers the albedo (reflectivity) of the surface. This would cause the snow/ice surface to absorb more solar radiation by virtue of its lower albedo, which would allow it to heat up more. Normally most solar radiation is simply reflected by snow back into the atmosphere and mostly out to space, so by causing it to absorb more you are heating up the lower atmosphere. By doing this, you are more likely to melt the snow/ice, whereby the albedo will be even lower, which would then absorb more radiation, etc.. This is called a positive feedback loop.
What is the difference between albedo in rural and urban settings?
"Albedo" is the refectivity of something. Snow and ice have a high albedo since they are white. Pavement has a low albedo since it is darker. Albedo is important because it reflects sunlight back into outer space. As more and more glaciers, snowpack and pack-ice at sea melt away, less sunlight is relected into space and more light is absorbed as heat by the land and sea. This heat accelerates global climate change.

How does sea ice help keep the planet cool?
Sea ice helps keep the planet cool by reflecting sunlight back into space, which reduces the amount of heat absorbed by the Earth's surface. This process, known as the albedo effect, helps regulate the planet's temperature and climate.

A low albedo means that a surface absorbs more sunlight and heat, leading to warming. This can contribute to climate change by increasing temperatures and melting ice caps, which in turn can lead to rising sea levels and changes in ecosystems.

The sea surface temperatures are warmer or cooler due to melting the water?
Melting ice does not directly affect sea surface temperatures because the temperature of the ice is already at freezing point (0°C). However, as the ice melts, it can impact local water temperatures through changes in albedo and heat absorption. This can contribute to overall changes in global sea surface temperatures over time.

Is there soil in the sea?
yes i think that there is soil in the sea
How does melting of glaciers and sea ice lead to more melting?
When glaciers and sea ice melt, they reduce the Earth's albedo (reflectivity), causing more sunlight to be absorbed rather than reflected back to space. This leads to increased warming and further melting of glaciers and sea ice. Additionally, as ice melts, it exposes darker surfaces underneath (like water or land), which absorb more heat and perpetuate the melting cycle.
How is the melting of Arctic sea ice contributing to climate change?
It does? Yes, it does. Before it melts, the ice reflects the sun's rays back out into space. This is called the albedo effect. After it melts, the sun's rays land on the black waters of the Arctic Ocean, which doesn't reflect the rays, but absorbs them, and the water gets hotter. This is how the melting ice causes more warming.
Why does higher temperatures reduce the annual volume of sea ice and expose more open water in the Arctic Ocean?
Increasing the temperature more ice is melted.
