What does the polar ice caps melting mean?
Polar ice caps are melting as global warming causes climate change. We lose Arctic sea ice at a rate of almost 13% per decade, and over the past 30 years, the oldest and thickest ice in the Arctic has declined by a stunning 95%. Sea ice loss has far-reaching effects around the world.
What are three effects of polar ice caps melting on Earth?
Additionally, melting ice has other side effects on the planet – such as sea level rise.
- Melting ice causes more warming. When solar radiation hits snow and ice, approximately 90% of it is reflected back out to space.
- Melting permafrost releases greenhouse gases.
- Less ice on land means sea level rises.
What are the effects of polar ice melting?
Consequences of Ice Caps Melting When the Antarctic melts, climate experts state that sea levels can rise to 200 feet and more. Greenland’s melting ice sheet will add another 20 feet to sea level rise. So all together, the melting of polar ice caps effects would include sea levels rising 220 feet or more worldwide.
What is the reason for melting of polar caps?
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 is glaciers melting a bad thing?
Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
What would happen if the polar caps completely melted?
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. Scientists are studying exactly how ice caps disappear.
How does climate change global warming affect human health?
Hot temperatures increase the ozone concentration, which can damage people’s lung tissue and cause complications for asthma patients and those with lung diseases. Increased global warming can also pose a threat to national security, affecting food security, which, in turn, can lead to resource conflicts.
