We learn a lot from studying fire scars in tree rings. We are able to figure out the exact years and even season of past fires, going back through time. For example, in the Piedmont of North Carolina, we recently found that fires occurred every few years over previous centuries by studying the fire scars. If you’re interested in learning more, there are a lot of great general resources!

A great introductory text to tree-ring science is:

Speer, J. H. (2010). Fundamentals of tree-ring research. University of Arizona Press.

An excellent overview article that discusses using tree rings for fire history is available here (Falk et al., 2011 - Multi-scale controls of historical forest-fire regimes: new insights from fire-scar networks):

Here’s another article on next steps for tree-ring based research on fire (Harley et al., 2018 - Advancing Dendrochronological Studies of Fire in the United States):

What's the oldest fire you have identified?

Tree-ring science (also called dendrochronology) is very useful for studying the fire history of a given area. The tree rings contain evidence of past fires in the form of fire scars. These fire scars form when the heat of a fire moves past the base of the tree and causes a small injury, but doesn’t kill the tree. Fire scars can be dated using tree-ring methods to find out the exact year and approximate season of past fires that occurred at the site over the life of the tree. An essential part of the research includes crossdating - a process of pattern matching that ensures that each tree ring is dated to its exact year of formation. In longleaf pine, we are finding fire-scar evidence that proves fires occurred historically every 1-4 years.

I’ve never been a big tobacco user, but lately I’ve been using camel snus pouches. How bad are these for me?

Crazy. Literally everyone in my family has hit the genetic lottery in that case. Most smoked for 40+ years.

I recently quit vaping after 7 years, and I currently use 6mg pouches. My question is, how would you say vaping’s health consequences compare to smoking, or say patches/gum?

Can you offer any explanation of why many patients who use Varenicline exhibit horrible nightmares?

I'm in the same boat. I don't like that I still use nicotine, but it's good to hear I'm not likely to lose my jaw to mouth cancer from it.

Is Lily a completely made up character or did you insert some of your own feelings and experiences into the character from your experiences in Taiwan?

For the lungs, what is worse: cold or warm smoke?

Are there other chemical substances around that provide similar effect as nicotine?

It says “one of the first” so I’m pretty sure all that means is that they’re on the upper end of the gen Z age bracket and not that they got in literally first

What was your process like for getting an agent?

Calling yourselves "the first traditionally published GenZ book authors" sounds fake and gimmicky. I've seen articles about genZ authors for at least 5 years now -- are none of them traditionally published? Maybe shift the narrative from "we got there first" to "we offer a perspective unique from all the other first-generation-immigrant college kids".

That said, congrats on the book! What literature trends would you like to see become more mainstream in the next few years?

The book looks wonderful and is a great take for children who have experienced a move - and their parents. What brought you to this idea?

Cute looking book. Who did the illustrations?

Where do you find the gall to publish a book while still in college?? /s

I’d recommend searching Dr Attia and Dr Huberman who have both separately spoke on their podcasts regarding the use of nicotine (outside of smoking) and it’s potential benefits and health risks.

Users, please be wary of proof. You are welcome to ask for more proof if you find it insufficient.

OP, if you need any help, please message the mods here.

Thank you!

Cold withdrawal doesn't work for me, i also tried nicotine gum, vaping and patches.

I won't try questionable methods like hypnosis either.

What alternatives do you suggest for giving up smoking long-term?

There is not enough proof included in the post that connects your identity to the IAmA.

Unfortunately, the links or photos you've posted could have been posted by anyone, and they don't prove that you are the person doing the AMA. Your proof needs to be something that connects the fact that you're doing an AMA with your identity. This could be something like a photo of you in a work uniform or at a relevant location with a sign that has your username and the date. It could also be documents (partially redacted if desired) with a note that has your username and the date. We're happy for you to get creative with your proof as long as it makes it clear to a reasonable person that the person doing the AMA does meet the criteria laid out in the topic of the AMA.

If you can't think of a way to prove your claims publicly, you can also submit confidential proof to the moderators at this link, though bear in mind it may take some time to review.

Here's a link to the section of our wiki that discusses proof.

Please edit your post and add new proof, and reply here to let us know. If your post is more than a couple of hours old, it may be more effective to create a new post and include the proof from the start. Thanks!
