No, both conditions would make the earth cooler.
Few things have higher albedo than ice - farmland is lower, but still higher than the forest which it probably replaced.
Albedo is a measure of reflectivity; it is a measure of the percentage of light reflected from a surface. A perfect mirror would have an albedo of 1, while white snow has an albedo of about 0.9. Charcoal has an albedo of about 0.04.An albedo higher than 1 is impossible.
naturally sea ice would have the advantage of having a greater albedo
A higher albedo would mean that more energy would be returned to space. This would mean a cooler climate.
There is more ice on Antarctica to reflect the sun's rays back into space -- albedo, than there is in the Arctic Ocean.
A higher albedo means that a higher percentage of incoming light is reflected.
A higher albedo means that more of the incident radiation is reflected, and less of it is absorbed.

Albedo means reflectivity. The higher the albedo, the more light (and heat) is being reflected. Generally, the darker the color, the lower the albedo : most of the energy is absorbed. Snow has a fairly high albedo, as do clouds. Black tar roofs have a very low albedo.

they are spread farther apart, causing the air to get thinner, making it harder to breathe. ;P
The temperature is getting higher because of the gases and because of that the ice is melting and in several years we all can die because we will drown.

The temperature and pressure in the sun are just a bit higher than anywhere on Earth.
Temperatures are becoming higher than expected. [APEX]
