Apparently, the oceans are warming around the Antarctic continent, thus melting the ice shelves from underneath.
This is an odd question, although I suppose that the gases that are most affecting the animals near the Poles contribute indirectly. The gases you are referring to are called greenhouse gases, like carbon dioxide and methane. They don't so much affect the animals near the poles directly, but more the environment in which these animals live. The greenhouse gases contribute to the melting of ice caps and icebergs which, in turn, does affect polar animals like penguins and polar bears.
Jack Hall was studying the greenhouse gases in ice cores from Antarctica because runaway greenhouse gases are causing global warming.
To trap heat. The functions of greenhouse gases are to absorb heat from sunlight and trap it in the atmosphere to warm the Earth and melt the ice caps.
The question probably refers to "greenhouse" gases rather than green ice gases. Greenhouse gases are a group of gases in the atmosphere that tend to prevent heat escaping from the Earth. They act rather like a blanket and hold heat in the atmosphere. There are several greenhouse gases. The best known are carbon dioxide and methane although water vapor is also one of them, even if not usually recognized as such.
It is affecting our planet by melting the polar ice caps which will eventually kill us all.
Absolutely! burning fossil fuels creates harmful fumes that go into into our atmosphere. These fumes are known as greenhouse gas. Greenhouse gases are affecting global warming and are causing our ice caps to melt.
One theory is to increase the input of greenhouse gases so that the next "ice age" can be averted.

Greenhouse gases in the atmosphere are reflecting more and melting the polar ice caps.
The answer you want is about 70%.
Icebergs are made of ice and since the greenhouse gases are making the earth warmer the icebergs are melting.
Greenhouse gases have kept the planet comfortably warm for millions of years. This has been an advantage.Now, however, there is an excess of greenhouse gases (mostly carbon dioxide from burning fossil fuels). This extra greenhouse gas is causing an accelerated greenhouse effect which is causing global warming. This is a serious disadvantage!
