Not CO2 for what it’s worth

Your source article (American Thinker) appears to have conveniently ignored a number of factors influencing current temperature increases along with the unwarranted suggestion that we can now blame it all on the Tongan underwater volcanic eruption. It's true that the volcano will/is having an effect, but it's only one of four significant influences currently raising temperatures above the norm.

• The first factor is increases in atmospheric CO2 levels resulting in the cumulative ongoing process of global warming, aka Climate Change,
• The second is the El Nino ocean cycle which is currently heading into a warming phase,
• The third is the Suns regular 11 year cycle of fluctuating energy output. We are currently headed for the warmer end of the cycle.
• The fourth - is the volcano. The amount of water vapour emitted will result in a small increase in temperature which will decrease over the next 5 or so years as the vapour dissipates.

Note that three of the four causes are one-of or cyclic while one cause (CO2) is ongoing and cumulative. This graphic illustrates the relative contributions of all four factors.

N2O for what it's worth.

N2O for what it's worth.

Laughing gas?

Laughing gas?

Yup -- 6.2%

C02 was 0.03% of the atmosphere


After several decades it’s 0.04%

What's your point?

What's your point?

0.01%

 

[Occams Barber]

N2O for what it's worth.

Yup -- 6.2%

I agree that N2O is no laughing matter () when it comes to greenhouse gases. In fact, pound for pound, it's a more dangerous greenhouse gas than CO2.

Fortunately, there's much less of it, it doesn't last as long in the atmosphere as CO2 and there's much less being released into the atmosphere.

The big problem with N2O is its source. It mainly comes from agriculture and substitutes are more difficult to find. There's a similar problem with methane from cow burps.

Um ... N2O is 300 times more potent than CO2.

But science-driven journalism will harp on CO2, so they can bully the little guy.

Scientist: Put that pop can up!
Johnny: I will when you put that fertilizer up!

True

But science-driven journalism will harp on CO2, so they can bully the little guy.

Science and government is actually trying to bully the big guy. Most CO2 comes from industrial emissions (like power generation) and big transport. We need the big guy to switch to renewables and generate clean electricity etc. so we can all switch to electric cars and stop feeling guilty about turning the lights on and running the air conditioner.

Scientist: Put that pop can up!
Johnny: I will when you put that fertilizer up!

Scientist Big Agriculture: Put that pop can up!
Johnny: I will when you put that fertilizer up!

What about NO₂?
NO₂ is a deadly gas.
The scientists are the heroes here because they came up with the theory of surface catalysis and prevented life on Earth from being snuffed out of existence by NO₂ emissions.
Why do you think they did nothing about N₂O?
Answer because the "2" is in the wrong place.

Are you confusing NO2 (Nitrous Dioxide) with N2O (Nitrous Oxide)?

• Nitrous oxide (N2O): Nitrous oxide is emitted during agricultural, land use, and industrial activities; combustion of fossil fuels and solid waste; as well as during treatment of wastewater.

Leaving the sarcasm of my post aside NO₂ is nitrogen dioxide.
I knew of schoolkids of my generation having been hospitalized producing this gas in a chemistry experiment.
It is reddish in colour, highly corrosive and its safety data sheet indicates how dangerous it is.

Since car combustion engines produce high temperatures, nitrogen oxides NOₓ which includes NO₂ are produced when nitrogen and oxygen in the air in the cylinders react with each other and forms part of the exhaust gasses.
NOₓs are broken down when the gasses pass over the precious metal coatings in the catalytic convertor.

Like I say:

Don't harp on me to hug a tree, unless you bar your gas-powered car.

When's it going to cool back down? How long is this heatwave going to last?

 

[returntosender]

I keep thinking it's going to start declining and go back to normal?

 

[JohnEmmett]

When's it going to cool back down? How long is this heatwave going to last?

This should last a year or two

 

[returntosender]

So i should not wait to update my inadequate cooling? How will we have snow this winter?
