We used to get pretty big rhubarb down by Juneau without having to care for it. I wouldn't be surprised giving long growing hours and good soil that they could get this big.
That's really unfortunate as it would be something to remember. Of course the original attendees might not feel up to a huge party. Considering that Wood Stock 94 ended up being overrun by attendees maybe they thought it would be better not to repeat that event. https://en.wikipedia.org/wiki/Woodstock_%2794
I'm not sure a personal cooling device is the answer we're looking for. There are many other things like fabrics and materials that could be used to cool instead of hooking another device to your body. Sure it sounds cool but is it the easiest solution?
The other question is what is the global impact of all the electrical use from these cell phones? I think the demand for a cellphone(smart phone) to be energy efficient is going to be a greater concern than all it's doodads and widgets.
Unlike the last time they aren't working from scratch. NASA has been designing Mars suits and has all the data from that last moon suits. With 3D printing and modern materials I think they could begin testing quickly once designs were chosen. Likely they take the chance to test the Mars suits with Moon adaptations.
Mumia was a kind of cure all and that was originally produced from naturally occurring bitumen pitch. When latin translators translated Mumia pitch from Arabic medical journals they falsly assumed it was pitch made from the Mumia(mummies) instead of the bitumen pitch before it was put into a mummified body. During the crusades hearing about the drug mumia's healing properties cursaders brought stories of it back to Europe. Mumia was so strong that perhaps it could cure the dead which may have lead to the Mummy rising from the grave stories though there is no way to know if there really is a connection.
Then I am equally as baffled. Maybe someone took a white castle burger and just wrapped it in an in and out burger wrapper. We'll need CSI to verify the origin of those patties and buns.
Regular flooding used to be more common. It's not to say that this isn't exacerbated by the current climate crisis but we have foolishly build our homes and businesses in flood plains. It's sad to lose the beaches but a sign that we need to prepare for worse.
Several million years is long enough to evolve a new answer. Perhaps we'll find a second version of Y chromosomes emerging from X chromosomes. New men vs. old men.
