Temperature need to melt this ice in 400 years

In summary, heat is needed to melt ice -30C that covers an area of 34 million km2 and has the height of 11.4 km in 400 years. For example, X number of celsius degrees are applied non-stop for 400 years in order to melt this ice entirely from the surface (turn to water).

Heat melts ice, not Temperature.

Alright, heat then.

You need to show some work of your own, you can't just come here and ask for an answer. That's not the way the forum works. You should read the rules. If you don't follow them, you run the risk of your post just getting deleted (or closed).

Not so fast. The question specifies a time period and that the heat is applied at the surface. It also explicitly mentions degrees C. So it might really be looking for a surface temperature which, if sustained, would melt all the ice in that time.
On the other hand, there are two snags with that interpretation:
1. The area would not matter
2. If you literally were to sustain a temperature > 0C then the surface layer would melt instantly. If that were to run off instantly, then the next ice would melt instantly, etc. So you'd have to suppose a certain depth of water at any time and consider the heat flow through it.
Aleksa, have you stated the question word for word as presented to you?
 

What is the temperature needed to melt this ice in 400 years?

The temperature needed to melt ice in 400 years depends on various factors such as the type of ice, the surrounding environment, and the rate of temperature change. However, in general, it is estimated that a temperature increase of 2-3 degrees Celsius would be needed to melt a significant amount of ice over the course of 400 years.

What is the current rate of temperature change?

The current rate of temperature change is a controversial and heavily debated topic among scientists. However, most agree that the Earth's average temperature has increased by 1 degree Celsius since pre-industrial times and is expected to continue to rise if greenhouse gas emissions are not significantly reduced.

What impact will melting ice have on the planet?

The melting of ice has severe consequences for the planet, including rising sea levels, changes in ocean currents, and disruptions to the global climate. It can also lead to the loss of habitat for various species and affect the availability of freshwater resources for human populations.

Can we prevent the melting of ice in the next 400 years?

While it may not be possible to completely prevent the melting of ice in the next 400 years, there are measures that can be taken to slow down the process. These include reducing greenhouse gas emissions, implementing sustainable practices, and investing in renewable energy sources.

What can be done to mitigate the effects of melting ice?

To mitigate the effects of melting ice, we need to take immediate action to reduce our carbon footprint and adapt to the changing climate. This may include building seawalls to protect coastal areas, implementing water conservation measures, and developing technologies to capture and store carbon emissions.
