But for sea ice to increase the air temperature in that area has to get cold enough to freeze the sea into ice. That is what is so hard to understand.
For there to be a global increase in temperature then not even sea ice should be forming.
As the decline in land ice could certainly be due to low precipitation and not allowing land ice to form.

Once upon a time everyone thought the world was flat until someone sailed over the edge of the earth and came back a few years later with tails of distant lands.
In that time period if you questioned the flat earth theory you would be ridiculed and told you were crazy.
That is what I think about this whole debate. The Great Lakes were still frozen in spring, which is the first time that has happened in decades.
It would be a lot better if the "peer-reviewed" scientist would just come out and admit that they don't know. Instead of calling people who disagree with them "deniers", "flat earthers", and neanderthals that don't understand the "science".
I just hope the future government mandated CO2 scrubbers are stylish.

It's simple really... when the land ice melts into the sea due to warmer air, it cools the sea. It's like taking a warm cup of water and adding cold water from your pitcher. The water in that cup it's cold now.
In the Antarctic, temperatures are far enough below freezing that even with some global warming, temperatures could remain sufficiently cold to prevent extensive surface melting.
m.earthobservatory.nasa.gov...
However, the record to date is not clear enough to make any definitive conclusions about long-term climate trends based on the sea-ice observations alone. Sea ice varies significantly from season to season and from year to year, and the extent of its natural variability is not yet fully known.

If some places are getting hotter while some are getting colder, it's bunk. For Man Man Global Warming to be a real thing global temperatures from all across the global need to have an uptick. It can't be hotter in one place, while being colder in another place, because the theory of Man Made Global Warming means hotter global temperatures as a whole which means hotter winters.

I get what you are saying and I get the argument, but nobody has yet come up with a plausible theory as to why all this change is being caused by humans.
The explanation you are giving is that the climate fluctuated a lot in the past, but in the 150 years since we have kept relatively accurate weather records we have seen an uptick in temperature so it has to be caused by man, because the C12/C13 isotope only occurs by the burning of fossil fuels.
When the earth naturally leaks oil and they are now starting to discover that this C12/C13 isotope probably occurs in nature a lot more often than they previously thought.
Not only that, but it still doesn't explain how you can say overall global temperatures will increase 1 degree Celsius(or whatever it is), but then shrug off the expanding sea ice as not being a factor when in reality it shouldn't get cold enough for that sea ice to expand it the rate it is precisely because the Man Made Climate Change theory states that Global Temperatures will increase as a whole.
The sea ice should have stayed melted.
See the problem? Overall sea ice is not actually increasing. Things are happening much differently in the Northern Hemisphere than they are in the Southern Hemisphere.

No, the problem is that just a few years ago they were pointing the disappearance of the sea ice being a key indicator of Man Made Global Warming and the rise of overall Global Temperature.
Now the sea ice is returning which shouldn't be happening because the earth has warmed to the point where the sea ice should still be receding.

Do you see the problem with the logic?
You can throw all these charts and all this "science" from "94%" scientist in consensus, but it still won't explain away the fact that if Global Temperature was increasing the sea ice that already melted and disappeared shouldn't be coming back, because the Global temperature has increased to a point where the sea ice can't form.

I feel like you are being deliberately obtuse but in case I'm wrong let me try to explain and try to clarify some of this. Yes Polar ice ebbs and flows every year both on land and on the ocean. New sea ice does form in both places each year however the recent increase is largely due to increasing land ice breaking off into the ocean and an increase in number of glaciers flowing from the land into the sea.
Global warming does not mean instantly too hot for winter anywhere. The planet will continue to have cold arctic winters and cold antarctic winters for quite a long time yet. The planet has warmed .8C degrees since the industrial age began, not a lot... yet, but the global temperature continues to rise although at slower rate for the past 15 years or so than previous. The reason for this is that the oceans have been absorbing the heat (one of the candidates for the increase loss of ice from the sheets and growth of sea ice). But even that seemingly small increase in global temps has been enough to cause climate change.

More sea ice is due to melt and calving into the sea. Growing sea ice is evidence of warming or volcanic activity under the ice, not cooling.
