Permafrost Melting, Lakes Disappearing and a Question
I don't think there's doubt in any one's mind anymore that the Earth is warming up. Global warming is a fact.
The only thing that I'm not sure about and will be happy to be educated if any one wants to direct me to the right place is - How do we know the Earth is warming at a different rate than before? Don't we have better technology and instruments now that can measure whereas before we didn't? So how do we know that the Earth wasn't warming up before, but we just couldn't measure it?
Unless what they're saying is that the warming is a natural occurrence and we're just helping it, accelerating the warming with the pollution?
Anyways, it's starting to get scary:

Anyways, it's starting to get scary:
A new study finds 125 large lakes in the Arctic have vanished as temperatures rose over the past two decades. Many other lakes have shrunk.Link
The lakes once sat atop permanently frozen soil called permafrost. Other studies have shown permafrost is melting around the world, causing low-lying ground to slump and rock to fall from mountains.
