Is Climate Change science?

The folks over at Clear Energy Alliance raise the question of whether or not climate change is science.

Their point is that since proponents of man caused climate change blame everything, even contradictory things, on climate change it's not possible to construct an experiment that shows that climate change isn't real.

For example climatistas say that warm weather and cold weather are both due to climate change.  Which means we can't measure the earths temperature and show that climate change is wrong since no matter which way the temperature goes the climatistas say that that's due to climate change.

This is a fundamental flaw with the theory; if everything can be explained by climate change then it's impossible to show that the theory is wrong.  But if you can't falsify a theory, show it's wrong, it's not science.  That's because if you can't show that a theory is false you also can't show it's true.

This argument doesn't require any knowledge about the actual climate or about what the earth's temperature is since it's basically saying that climate change is so flexible that it can explain the earth's climate no matter how the climate changes.  Basically the theory can be "adjusted" to show that it would have predicted what we see if they'd only made the right assumptions before what we saw occurred. But as they say hindsight is 20/20 so a theory that is only right after being corrected to match the data is no theory at all.

Keep in mind that this argument is in addition to all the ones that show that the data as measured doesn't support the climatistas frantic warning.

For example the rate at which the oceans are rising has been constant even as mankind has been adding lots of CO2 to the atmosphere.
