- If you are in passing Chicago while driving East on I-80 at 70MPH, how long before you arrive in San Francisco?
- If Antarctica is gaining sea ice steadily at a rate of 0.15 million km² / decade, how long before 40% of the ice is gone?
- If more than 90% of what Hansen predicts turns out to be nonsense, how long before an ostrich pulls its head out of the sand?
1. 15 days
2. A few months, the time needed to figure out an adjustment
3. Hansen is never wrong. When he is, his original computations are modified alongside history

The questions and your answers seem like the NetFLix ads
So you win a BIG THAT’s CORRECT
Maurizio – #1 depends on factors like rush hour traffic, road repairs and not getting shot driving through Gary Indiana.
1. That’s only a one-day speed. How fast were you going 600 years ago? 0.028c?
2. You can’t possibly compare a multi-decade trend with what happened for two weeks in 1998.
3. James Hansen wasn’t working for NASA in 1906, therefor your question has no bearing on the fishdicks mom made for lunch. God, I love fishdicks.
Well, if land ice is truly decreasing (as measured by GRACE and radar), there will come a time where the sea ice is not replenished.
I still await the response of an AGW skeptic to rebutt this.
Even so, if land ice is decreasing, GRACE and radar do not prove why (i.e. doesn’t prove AGW). Not sure how land ice can melt if the temp is below freezing, but loss due to sublimation exceeding replacement from diminished snowfall is a possible explanation.
Land ice increases by precipitation.
Sea ice increases by the water freezing, & by the movement of ice from land sources, and perhaps some from precipitation. To reasonably reach the conclusion that sea ice would not replenish you would have to eliminate both major sources of sea ice, not just one.
I’m rather assuming you’re talking specifically about Antarctica, because I’m fairly sure the land contribution to the Arctic’s sea ice is quite small.
As to whether or not there will ever come a time when sea ice is not replenished you would have to use far more specific language. What time-frame would you consider replenishment? At what minimum extent would you consider it unreplenished? In a few billion years, the Sun will go nova, which will leave the sea ice undernourished, but I don’t think that’s what you’re talking about.
