Do all rocket engines emit harmful gases into the atmosphere during launch?

Also, reusable rockets will likely lead to the end of the use of solid fuel rockets that are most harmful to the environment. In 15–20yrs I expect solid fuel rockets to be history. The technology might hang on longer in missiles.

In short, if you believe the climate alarmist, “He dies. She dies. They die. We all die excruciatingly painful deaths from climate change.”

Climate alarmist point to ancedotal correlation in the past few centuries that suggest an anthropic relationship to climate warming. Once you go back tens of thousands of years and more that ancedotal evidence falls apart fairly quickly. There multiple periods where climate warming precedes CO2 levels rise indicating that climate warming causes increased atmospheric CO2.

Most people obey arbitrary rules even when it's not in their interest to do so, experiments show - Phys.org

Therefore, I wouldn't let your panties get in a wad over rocket exhaust.

The UN in 2001 adopted Allen and Tett’s paper as the “gold standard” and subsequently accepted several climate models that were improvements on Allen and Tett.

One of the most prolific papers supporting anthropic climate warming, “Optimized Climate Fingerprinting,” by Allen and Tett, 1999, published in the Journal of Climate Dynamics was overturned in 2021. “Suboptimal Climate Fingerprinting,” by Ross McKitrick published 2021 in the Journal of Climate Dynamics overturned Allen and Tett. In doing so, it overturned 19/50 or 38% of the climate models in the UN IPCC climate suite.

I caught my husband of 20 years looking at inappropriate pics of women on TikTok or Instagram. I'm not sure., but when I told him he got mad and made excuses of why they popped up. I then told him how I've snuck on his phone and saw what he's been looking at . We had a horrible big fight. I asked him why did he even marry me when I see the type he likes . Nothing like me, I'm petite, blonde and blue eyes. These women are dark haired dark eyed and have curvy bodies, large breasts, etc. I just don't feel the same about him after this. I can't get over this

Therefore, it seems prudent that humanity becomes an interplanetary species now. Humanity must become interplanetary at some point in order to survive as a species.

Yes. Water vapor is the only exhaust from a LOX hydrogen fueled rocket. Climate alarmist have correctly recognized that water vapor is the strongest and most persistent greenhouse gas. All other rocket engines, liquid and solid, burn some form of hydrocarbon that emits CO2 among other gases.

Celebrate Jesus! Celebrate rockets! Ignore climate alarmist until they have solid experimental science!

Several climate modelers used Allen and Tett's data that was flawed. Allen and Tett had over 12 errors in their paper and most of them were mathematical.

The points being is that climate hysteria is based on psuedo science, without good experimental evidence to support CO2 as a significant greenhouse gas.

There is however good statistical evidence to support two cosmic cataclysmic events a due to hit Earth. One is a major asteroid impact of Tunguska size or greater. The other is a Miyake EMP event that will be over 100X the magnitude of the Carrington event. Either event would likely collapse civilization through mass starvation that leads to major war.

What are the possible reasons for people feeling depressed after the holiday season? Why does being alone exacerbate these feelings?

I just wish the climate alarmist had solid experimental evidence that CO2 is a greenhouse gas strong enough to effect the climate. They don't because it's not.
