Now he will deny you facts and possibly introduce more garbage. It never ends. They cannot accept the truth , probably is a trumper too.1. Because it's on land, and a desert. So the temperature stays much colder due to lack of the temperature modulation that is a feature of large bodies of water.
The Antarctic gets very little moisture, but, that which it does get.....stays. For millions upon millions of years.
2. Once again, water. The area you speak of on Greenland is high altitude LAND. It gets snow, it stays.
3. The oceans warm and cool constantly. There are far more factors that go into hurricane production than mere ocean temps.
4. Land sinks all of the time. The oceans may be rising, but it is at a rate so slow that it is nearly impossible to measure. Suffice to say the alarmist claims are nonsense.
5. CO2 does none of those things. What you are talking about happen independently of CO2.
