What are 2 possible reasons the glaciers are melting?

Causes of Melting Ice Glaciers

• Burning of fossil fuels. The burning of fossil fuels has resulted in the buildup of greenhouse gases in the environment thus influencing the warming trend because they trap heat in the atmosphere.
• Oil and gas drilling.
• Deforestation.
• Ice breaking ships.

Why is Antarctica’s ice melting?

Human activities are at the root of this phenomenon. Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.

Why ice shelves are melting?

Scientists attributed rapid ice shelf collapse to warmer air and water temperatures, as well as increased melt on the ice shelf surface. Warm air melts the ice shelf surface, forming ponds of meltwater. As the water trickles down through small cracks in the ice shelf, it deepens, erodes, and expands those cracks.

Why is there ice in Antarctica?

In winter, Antarctica is on the side of Earth tilted away from the sun. Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets.

How does global warming affect the Arctic and Antarctic?

The warming of the Antarctic Peninsula is causing changes to the physical and living environment of Antarctica. The distribution of penguin colonies has changed as the sea ice conditions alter. Melting of perennial snow and ice covers has resulted in increased colonisation by plants.

How does global warming affect the icebergs?

With a warming globe, more melting icebergs and Arctic sea ice could change this pattern. Melting ice means more fresh water to make the surface water in the ocean less salty and less dense, a process called freshening.
