More to learn on climate change

It seems professor John Christy has drawn a lot of vindictive criticism for his assessment of the global warming/climate change issue.

He does not deny the existence of climate change, as his detractors claim in order to dismiss everything he said. For one, he said there is no way for the scientific body to prove just how much change is caused by Mother Nature and how much is caused by human activity. Well, is there? So, how can it be settled until we know?

Do today’s scientists now claim that nature no longer has any effect on climate — that it’s only affected by human activity?

It seems to me that the only evidence they offer is the melting of polar ice and that it can’t possibly be caused by the sun.

Then, pray tell, what caused the mass of ice and snow in the northeastern part of the country to melt away?

So, like Christy, I don’t deny the fact that climate change exists. Like him, I’m just asking questions.

For example, is all there is to be known about the cause of climate change already completely known?

That is the only way any scientific subject can be called settled science, such as the existence of gravity.

Why criticize anyone for just asking questions?
