Wow. Talk about the Pot calling the Kettle black!

There is no video on your post, but I assume it was a “guilt by association” piece blaming all opposition to your views as being in the pay of Exxon Mobil.

My information did not come from Exxon Mobil; it came from Freeman Dyson, perhaps you could read it rather than assuming it is funded by the evil ogres of Big Oil: http://www.thegwpf.org/content/uploads/2015/10/benefits1.pdf

Melting sea-ice already displaces its weight in water, so cannot cause sea levels to rise, even if all sea-ice were to melt. You then ask “What sort of physics is that?”

It is real Physics: if all the icebergs and ice-shelves floating at the North Pole or off the coast of Antarctica were to melt tomorrow, the sea-level would not change one iota. Look up Archimedes and why he said “Eureka!” This is high-school Physics that everyone should know. Only Land-based ice melting can raise the sea level.

The worst-case scenarios the IPCC are trotting out amount to 4°C: I doubt we will ever get more than 1°C this millennium but it doesn’t matter: at an average temperature of -30°C, even 4 degrees won’t make the ice-caps melt. You should be able to understand this:

1. Only ice that is not already displacing its weight of seawater can raise the sea-level. Not floating ice, land-based icecaps must melt.
2. The projected worst case scenario warming will leave both ice-caps (Greenland and Antarctica) well below 0°C virtually all the time.
3. 0°C is the freezing point of water. The ice caps won’t melt.

“ This is as logical as stating that frozen food is useless because it is inedible.” No it has nothing in common with that; it is more like “Your frozen food won’t melt if you keep it in the freezer.” This is the dumbest straw man argument I’ve ever seen.
