Global Warming? Could Scientists be this confused?..

I recently came across these articles from quite a few years ago (about 30 years ago), and wondered...

• Is global warming "real"?
• How could science be this far "off"?

Here's another from Newsweek...

Now I have to wonder...

• If what this says is true, then the receding of Arctic ice must be bringing things back to "normal"!?
• How does society forget so quickly?

It seems to me that there must be now or have been then, a lot of confusion concerning our planet and our climate.  Tell me what you make of all this.
