What is the evidence that Mars is warming?

A NASA scientist took two measurements of albedo (the amount of radiation reflected by the planet) one from 1977 and one from 1999 and calculated using a Global Climate Model that the change in albedo was consistent with a small temperature change.

What is causes changes in albedo?

On Mars, it's dust storms.

Were any actual changes in temperature measured?

No. Just changes in the light and dark areas on the surface measured on two different days about 23 years apart, presumably caused by dust storms.

Two different days? You mean there is no long term observation that the changes in albedo are increasing in one direction instead of just changing randomly?

Nope. Two points don't make a trend.

So it doesn't sound like there is any evidence that the temperature on Mars is increasing.

Nope.

So why do people bring up this argument?
