Global Warming. Here's the thing.

[Stryder50]

Temperatures have been rising since the end of the Little Ice Age. Weird.

Only an insane person, or a paid denier, could think that much extra CO2 wasn't making any difference.

How much difference does each billion tons make? Link?

Temps may have risen since last "Little Ice Age", but not as much as since the end of the Last Major Ice Age about 15,000 years ago.

Only an insane person, or a paid promoter, could think that much extra CO2 is really making any difference.

What is the ratio of that extra"billion tons" to the hundreds/thousands of tons already in the atmosphere?

At 400 ppm = parts per million (400/1,000,000 = 1/2,500), every molecule of CO2 is overruled by 2,499 molecules of other gases in the atmosphere ~nitrogen, oxygen, argon, etc.
And that's not counting the 10-20% addition of water(H2O) vapor.

Try getting a grasp on scale and perspectives ....
a.k.a. REALITY!
