There is distinctly less ice in the second picture
However, I have read reports that this epoch of the Earth is unusual in that there is ice at both poles at the same time.
Perhaps the climate is actually rebalancing itself
The fact of the matter is, we don't know. But it doesn't mean we don't have to try and minimize our impact on it.
We can't afford to be wrong, after all.
And that's the whole point, we CAN"T afford to be wrong, and cleaning up our act can do nothing but good ... except to those who have an interest in keeping things the way they are, like the oil companies, and those who stand to make a financial gain from being sceptical, like the book writers and video makers claiming there is no global warming.
IMO the biggest cause of global warming, and lung problems, is the fumes from cars. If you don't believe me take a look at the pollution that hangs around the major cities. Especially in America. I can vouch for the difference in roadside vegetation since I was a kid 60 years ago. There was an abundance of it then. Now everything is dying or dead.
Sixty years ago there was approximately one car per street. Now there is more than one car per household. To counteract this we could all drive electric cars. They could have Battery Changing Stations instead of Petrol stations. They now have electric cars that can go more than 150 miles per charge and can go at a reasonable speed. Are we willing to make this change? I doubt it.
When I was young the cases of Asthma were few and far between and generally 'ran' in families. Now there is a sharp rise in the amount of Asthma cases. What has this to do with car fumes I hear you cry?. The inhalation of fumes from cars mimics the symptoms of Asthma. Couple that with poor diagnosis, which is common nowadays, and you end up with more cases of Asthma.

The best way to keep a secret:- Tell everyone not to tell anyone.
Seriously looking at that i can tell there is masses of change that has occured over the years.
