Heat causes any frozen liquid to melt. When a liquid is frozen, all of the atoms come together. When that frozen liquid is heated up, all of the atoms move away from each other which causes it to melt.
The sun affects mountains through heating the tips of them up, this causes snow/ice on the top of them to melt causing flooding of local rivers and stream. it can also cause land slides. if there is no snow/ice then it will just cause a increase in temperature.
sunlight isn't what makes the ice cream technically melt faster. if you were standing outside in the winter, the ice cream doesn't melt as fast as in the summer. what really causes the ice cream to melt is the heat. the heat changes the physical property of it thus causing it to melt faster.
Gas does not directly cause Ice to melt. However if you are talking about glaciers then the gas Carbon Dioxide (CO2) causes the earths atmosphere to heat up (because it traps more of the Sun's heat) and this causes glaciers to melt - because the Earths climate is hotter.
