It's about the same impact that a 0.04% width of steel has on the flight of a bullet through 5,000 metres of atmosphere.

The vast bulk of the atmosphere is transparent to infrared radiation, it has no insulation properties at all to speak of.

The only reason our planet isn't a freezing ball is the actual insulation we do have .. and that's the 0.04% you're so flippantly and ignorantly dismissive of.

When that insulation doubles or halves it's a big deal indeed .. and yet still a tiny percentage of the atmosphere.

Try swallowing 0.04% by your body weight of a toxin and tell us how that goes .. by your "logic" that should be trivial to shrug off.

Are you saying that things whose concentrations are expressed in what in your daily life is a small number are unimportant? Would be great if you could be completely explicit about this, so that people can reply to something concrete. Thanks.

I'm very disappointed to see climate change deniers on this forum.

The effect of carbon dioxide on global warming has been proven a million times over. Small percentages can significantly affect heat capture from the sun. A quick overview[1].

Even at 0.1% CO2, you'll feel it (light-headedness, dizzy). Around 3-5% you'll be dead.

CO2 is rising at a rate 100x faster than pretty much ever. But you're right, its only 0.04% i'm sure we'll be fine [2]

And botulinum toxin only needs to exist in microscopic quantities to cause injury and death—would you eat a jar contaminated with it?

You mean like alcohol were 0.08% could bring you in trouble?
