Does the Presence of Ice Sheets Affect Earth's Energy Balance?

In summary, global warming is causing glaciers to melt at an accelerated rate, with the Earth's average temperature increasing by 1.8 degrees Fahrenheit since the late 1800s. Not all glaciers are melting at the same rate, as it depends on their location and surrounding climate. While glaciers can grow in size, they are crucial for the environment as they act as natural water reservoirs. It is difficult to predict the future of all glaciers, but if global warming continues, it is possible that they could all eventually disappear.

Homework Statement



The presence of a huge ice sheet helps support itself by changing the amount of energy the Earth receives.Question 13 options:
True
False

Homework Equations


none

The Attempt at a Solution


Ice sheets have high albedo, therefore Earth gets less solar energy?

Sounds OK to me.

Although discussing it in terms of "Earth receives" is an exaggeration, we talk about the local situation. It can be easily seen even on just a few square feet of snow how prominent is the effect of having clean white surface vs "dirty" snow.

Related to Does the Presence of Ice Sheets Affect Earth's Energy Balance?

1. Is global warming causing glaciers to melt?

Yes, global warming is causing glaciers to melt at an accelerated rate. The Earth's average temperature has increased by 1.8 degrees Fahrenheit since the late 1800s, and the majority of this warming has occurred in the last few decades. This increase in temperature is causing glaciers to melt and shrink.

2. Are all glaciers melting at the same rate?

No, not all glaciers are melting at the same rate. Some glaciers are melting faster than others, depending on their location and surrounding climate. Glaciers in warmer regions or at lower altitudes are melting faster than those in colder regions or at higher altitudes.

3. Can glaciers grow in size?

Yes, glaciers can grow in size. This happens when the accumulation of snow and ice is greater than the rate of melting. This typically occurs in colder climates or at higher altitudes where the temperature is consistently below freezing.

4. Are glaciers important for the environment?

Yes, glaciers are crucial for the environment. They act as natural water reservoirs, storing freshwater that is released slowly during warmer months. This is essential for maintaining water levels in rivers and providing a consistent water supply for plants, animals, and human communities.

5. Will all glaciers eventually disappear?

It is difficult to predict the future of all glaciers, but if global warming continues at its current pace, it is possible that all glaciers could eventually disappear. However, some glaciers may persist if actions are taken to reduce greenhouse gas emissions and mitigate the effects of global warming.
