Do airplane contrails add to climate change? Yes, and the problem is about to get worse

Nonsense. The rate of warming is at least 10 times faster. It's way outside the natural range.

There is no natural explanation for the directly observed stratospheric cooling, the increase in backradiation or the decrease in outgoing longwave in the GHG bands.

Natural forcing factors are trying to slowly cool the earth now, not warm it quickly.

The data says that the "it's natural theory!" is wrong, therefore rational people classify that theory as wrong. The "it's natural!" theory isn't at flat-earth levels of ridiculousness yet, but it's getting close.

 

The sun was warming in the 30s but today. If the sun constantly warmed without stopping, then we would be in big trouble. TSI is by far the largest factor from the sun because it is literally the heat from the sun hitting the earth. The sun also impacts clouds and the magnetic field but those are much smaller than the direct heat of the sun.

Here is a graph that shows the sun and CO2 going up in the 30s, and only CO2 going up today.

 

TSI is not the only significant factor.

 

Today’s rate of warming is mid range of the previous 9 warming periods. Where are all the climate refugees ???

 

Check it out. We've got a Trump follower suddenly forgetting about how terrified he is over the immigration of brown people from warm climates.

So what is another significant factor? Be sure to back up your claim with hard data.

We do know cosmic rays are not a factor, because climate and cloud cover have gone in the opposite direction of what the cosmic ray theory predicted.

 

Hilarious. You claim the people showing up at the southern border are climate refugees ??? That’s absurd. Where are all the climate refugees ???

You have my reference on clouds. There is a strong correlation of cloud coverage with cosmic rays. No model properly accounts for clouds.

 

You're not good at this logic thing, as you assumed the only immigration in the world was from Mexico.

Think Europe. You know, where you say are being deluged by scary brown people from Africa and the middle east. Think Syria, where the countryside emptied out into the cities.

No, I don't. I just have you claiming over and over to have provided references, without you ever actually having provided references. Same old same old.

That claim is debunked by the hard data.

A cosmic ray-climate link and cloud observations (Laken et al (2012))

At present, two long-term independent global satellite cloud datasets are available (ISCCP and MODIS). Although the differences between them are considerable, neither shows evidence of a solar-cloud link at either long or short timescales.

Investigation of cosmic ray–cloud connections using MISR (Krissansen-Totton & Davies (2013))

---
Our long‐term analysis of MISR data finds no statistically significant correlations between cosmic rays and global albedo or globally averaged cloud height, and no evidence for any regional or lagged correlations.

Molecular understanding of sulphuric acid–amine particle nucleation in the atmosphere (Almeida et al (2013)
https://www.nature.com/articles/nature12663
---
The ion-induced contribution is generally small, reflecting the high stability of sulphuric acid–dimethylamine clusters and indicating that galactic cosmic rays exert only a small influence on their formation, except at low overall formation rates.

See? That's how to actually provide references. And I can throw up another dozen saying the same thing.

Because you say so? Cloud effects are complex, but the models do pretty good with them.

We have two possible explanations for global warming. Yours shows no visible correlation and has no sensible theoretical underpinning, ours uses clearly understood physics and shows extremely good correlation. Golly, which one to choose.

 

An alarmist ^^^ claiming that anyone who doesn't believe that the current global warming is an existentialist threat is a RACIST. Too funny.

I've given you all my references which you choose to ignore.

There is no proof of human CO2 emissions causing our current global warming which is exactly mid range of all the previous 9 global warmings in the Holocene.

 

If I've reduced you to blubbering about racism, then I've clearly left you flailing. Why else would you deflect in such a stupid manner?

You've only given us a single propaganda piece that misrepresents the papers it references. It seems to be your cult bible.

There's a reason you can't reference the original papers. They all contradict you.

Sqawk! Polly wants a cracker!

 

It’s RACISM !!!

 

Just an interesting observation on this. Yesterday while sitting on the front porch enjoying a beautiful afternoon several jets crisscrossed the sky which is fairly unusual where I live. As I sat there over a couple of hours the con trails all formed into very long very wide clouds that did not disappear as they generally do. Maybe the weather conditions were just right or they were flying at just the right altitude or both but whichever they absolutely turned a sunny afternoon into a partly cloudy one.
