How hot are your colonists?

[digitCruncher]

Everyone else is super keen about ice and winter ... but I am wondering if anyone was like me and did the exact opposite?

I settled in a tropical jungle near the very bottom of my map, on what looked like the hottest tile in the world. After surviving to summer, I managed to get a heatwave near the peak temperature.

The highest recorded outside temperature during that heatwave was 67 degrees Celsius (152.6 degrees Fahrenheit). It was a thunderstorm outside. According to my understanding on mammalian biology, there is no mammal on earth that could survive that heat for more than a day (and this heatwave lasted for 3). I did have a freezer that was stuck at around 10C (50F) due to the extreme heat on the 'hot' side of the cooler, and a sleeping room that was around 38C (100.4F) (adjacent to the freezer by a single door, but no dedicated AC)

But that wasn't the hottest part of the map. You see I walled in my Geothermal Generator, not realizing that it produces a fair bit of heat. And so my record for the highest temperature was ... 82C (179.4F). And several people went in there for several minutes (one person managed to get a crematorium half-built before having to take a break from serious (but non-fatal) heatstroke. Pretty sure that that temperature would give you first-degree burns >.>

And after all that, the only fatality was a monkey trapped in the Geothermal building, who lasted about 3 or 4 weeks in temperatures constantly above 60C (140F), and only died on the third day of >78C (>172.4F) temperatures!

So ... yeah. Heatstroke probably should be buffed a little.

82C isn't that much. I regularly visit saunas that are around 100C. Air is bad heat conductor.
Working in those conditions however would probably result in a heat stroke after a couple of minutes.

Now if you'd jump into a 82C hot tub, that would be a different story

[Snowpig]

jungle areas usually have ~100% air humidity 

hot environment is the second thing i want to try with A8. atm messing around with cold environment.

[keylocke]

oh lol. wait until you get a solar flare + heat wave at the same time and crashed mech ship (forcing you to head outside into the heat...

fun times.. 

[Vas]

My colonist named "Vas Vadum", is so hot, the sun just got chills thinking about him.  :|

[Cat123]

Playing a boreal map - heat wave hit, temps outside went to 51oC.

So, hmm. Needs a bit of fine tuning.

[Snowpig]

why this? this is possible in reality - check eastern siberia: low humidity leads to very high temperatures in summer and very low temperatures in winter

No, this is false.

Siberia hits around 20oC in summer in its most forgiving parts.

This map shows the parts of the world that can exceed 50oC:

Rimworld might be science fiction, but there's no way for 51 oC to exist outside of deserts.

[Dr. Z]

But you said it was a heat wave, so of curse it was out of the natural bounds.

i admit, that 50 degrees is a bit high, but around 35 is possible.

I've lived in a house that has gotten to over 50*C inside - granted there was a bushfire on at the time. The days before and after were all around 48-49

The lowest temperature recorded in Yakutsk was −64.4 �C (−83.9 �F) and the highest was +38.4 �C (101.1 �F).

https://en.wikipedia.org/wiki/Yakutsk#Climate


Without getting into a massive debate over just why Yakutsk is so varied, the average for Siberia is still roughly 20oC in Summer (it has a lot to do with specific geography of that region - cf. microclimate https://en.wikipedia.org/wiki/Microclimate ). However, there's a huge qualitative difference between 40oC and 50oC.

It is, quite literally, the difference between a functioning ecosystem and one where no life can survive.

In contrast, the upper limit for eukaryotes is about 60�C, a temperature suitable for some protozoa, algae, and fungi. The maximum temperature for mosses is another 10� lower, vascular plants (house plants, trees) about 48�C, and fish 40�C.

Having a heat wave that raises local temperatures by 30 oC isn't a "heat wave" it's "massive solar flare, death of all life, bye bye colony". Having 67oC in jungle climates is just ludicrous - I hate to think what the desert biome produces.

I presume you're Australian then - in which case I'd advise moving, as your climate is not going to be pretty in the next 100 years.

The temperature is set to hit 44C in the west coast town of Ceduna, with 39C forecast for Adelaide, which would be a record early November maximum.

http://www.ozcoasts.gov.au/indicators/greenhouse_effect.jsp

The regions of Australia that have recorded temperatures over 48oC simply aren't parts where there are bush fires, fyi:




So, yes, this fits the thesis. Parts of Australia are already uninhabitable without serious outside energy / resource inputs, I'm not sure why you think that as temperatures go past 45oC that this region won't spread. Once you start hitting 48oC+, say goodbye to bush fires because there won't be any large vascular plants surviving to burn. If you need proof - that large brown splotch on the South - South West part of Australia is called the "nullarbor plain". From the latin, Null - none Arbor - trees.


It is quite literally called the place with no trees.

The regular, non-heatwave peak temperature in that region during summer is somewhere in the vicinity of 45C-50C or thereabouts. So I only had a 10C boost to my temperature during a heatwave. 30C isn't unheard of (Spearfish, South Dakota, had a 27C temperature rise in 2 minutes!), but I think the problem is that for the purposes of avoiding micromanagement, wildlife and humans have a *much* better time surviving in extreme temperatures than they do IRL. A 30C temperature rise for 3 days should kill all the native life, or give them *really bad* heatstroke.

Having 67oC in jungle climates is just ludicrous - I hate to think what the desert biome produces.

I picked a jungle biome because the temperature was highest there. The neighboring desert biomes were slightly colder.

But the highest temperature ever recorded on Earth was a mediocre 56.7C [Although that temperature is disputed. The highest *confirmed* temperature is 53.6C]. The 56.7C was recorded in 'Death Valley'.

I think this is the thing. In cold climates, things can survive better by simply having thick fur and thick blubber layers, but heat control in super-hot climates is a much harder challenge. Although, that said, people seem to survive better than I thought in places where temperatures regularly exceed 50C. That is to say, they actually can survive there! But nothing, not even bacteria, should be able to survive prolonged temperatures of above 60C. The FSIS (Food Safety and Inspection Service) says that the 'danger zone' for food is between 4C to 60C ... IE. at above 60C, food is just as safe as being refrigerated.

[Cat123]

No, no they cannot.

They can import a stay of execution through the expenditure of energy and resources that the local ecosystem cannot produce, but as the average temperature rises, so does this cost. The cost differential between living in 40oC and 50oC is something fierce, as Australia is about to discover.

Survival / fending off inevitable death; the two are not synonymous. Both McMurdo and Dubai rely entirely on imported energy - one for heat & calories, the other for water. (98.8%[1] of water in Dubai is produced by desalination plants, which are notoriously energy intensive; I'm sure you can work out the energy costs in transporting food to the antarctic).

Dubai's average temp. is only 40-42 oC in summer. If the gas was turned off tomorrow, Dubai would cease to exist within a few months. Same for Vegas and the abuse of aquifers and Lake Mead[2] that allows it to function.

I find it scary that people don't instinctively know that 50 oC = end of life, or quite understand just how much energy / resources are spent to maintain the illusion they're living in a place that isn't on the very threshold. The 20th Century - 4 billion years of life squandered to make the impossible happen in order to make glitzy casinos and societies based on slavery. Ceci ne pas un pipe.


On topic -

Temperatures are currently nonsensical - it'd be nice if beta testers had noticed this, but it needs fixing. Small hope of SimAnt levels of ecological modelling, but it'd be a better game if it wasn't totally History Channel about the topic.

Slightly off topic, but if you have a hallway (1-tile wide is best) connecting two rooms, you can really decrease the "heat leak" by filling the hallway with doors.  Any given door mostly blocks temperature, with a little leak.  (Linear?)  A bunch of doors in series block it even more.
