It can be, but depends on what typically triggers your asthma. Pollution and allergy-related may actually improve with elevation. But if cold or dry air are a problem, then altitude will generally make it worse. The best bet is if you're going to go up, don't do it too quickly. Allow yourself enough time to acclimate and see how you respond. smile

Antza, I think these are your best flower/bees/notsobees shots yet. The level of detail is incredible!

Thanks! happy And i agree, these are by far the best ones i've taken. I've learnt some neat tricks with my photo editing software to prevent ugly noise on high ISO images, so i can get a bigger focal point.

Some snapshots from another week visiting the high country in colorful Colorado.

I'm jealous. I would love to go hiking on a mountain someday, but so far haven't been able to because of my bad leg. Turns out i've had a spinal disc herniation for the last 4 years. Luckily i've now had it operated on and it's getting better. Hopefully i'll get to climb a mountain next summer. smile

Went exploring for a new perspective of my favorite volcano. Southeast-side view, good for catching the sunrise!







Looks like there was a small eruption or something at the steam vent since the last winter. A new dark mudflow goes all the way down to the treeline.

Yeah, thankfully this volcano doesn't tend to have very large or frequent explosive eruptions, and most of the activity is mudflows and lahars. Of course, any active volcano can have surprises.

The real scary one is Mt. Rainier near Seattle -- considered one of the most dangerous in the world. It's covered in glacial ice, and the underlying rock is very weak from hydrothermal alteration. So, if it goes, it will produce massive lahars that will engulf the neighboring river valleys. A lot of communities are built on top of old lahar deposits...

Finally the entire region is subject to infrequent but violent earthquakes from the Cascadia subduction zone, which runs all the way down the Pacific coast just off shore, producing quakes up to magnitude 8 and 9 with tsunamis that hit land just minutes later. It's a near certainty that it will go again (we can even measure the slowly building strain in the rocks)... it's just a matter of when. That's the risk of living in this beautiful area. Be aware and prepped for the disaster; hope it doesn't happen in your lifetime. smile

yeah and we must remember yellowstone too! its very close to washington and if it erupt...2/3 of the u.s will be covered in ash.
i will always say it...ppl dont care about future disasters (earth pollution, earthquakes, volcanos, and more) until it slap them in thier faces. and that one of the problems of today leaders and governments.

I saw a map for this, and even where I live (North Texas) will have at least a good coating on everything and I'm sure the air won't be breathable for quite awhile...And I'm hundreds, nearly a thousand miles away!

The scale of it is truly terrifying:



This basically ruins life in several states, and the climatic effects would be global. The economic impact is almost incalculable. It's so severe that there's really not much sense in trying to prepare for it on a personal level. You can't. The good thing is that these events are so rare that there's not much sense in worrying about it, either.

I think events like this also speak to how unfamiliar we are, as individuals, to what life goes through in the long-term. Earth's habitability is a gift and life is always at the mercy of whatever nature throws at it. Geologic time is best characterized as long periods of boredom, punctuated by short periods of sheer terror. There have been some pretty bad days. We're very lucky in that we have the intelligence and technology to prevent some disasters, like asteroid impacts.

On the subject of high altitude and oxygen, I thought the latest Smarter Every Day video was appropriate, educational, and a little bit scary:



He goes on an unpressurized flight which rapidly ascends to 25,000 feet (7600m), and under close supervision, removes his breathing mask to demonstrate the effects of hypoxia. I've heard, qualitatively, what this is like, but I've never seen it before. It's alarming. He gets down to about 60% blood oxygen level and becomes so impaired that he can't even comprehend the fact that he's about to die if he isn't put back on oxygen, let alone perform a simple task to save himself. You can see in his eyes that he's barely there; twitching and turning purple in the face, on the verge of passing out.

It's still amazing to me that the human body, given time, can adapt to and survive at that altitude, whereas sudden exposure to it would kill you in minutes.

The look on his face is pretty disconcerting, you can see how badly he wanted to put that mask on but couldn't even move his hands properly.

Too bad we still don't have respirocytes

need to be carefull when you going to such height. need to rest for a night every 1000 meters or so.
heard lot of stories of ppl who tried to climb that, felt not good up there and died somehow.
probably because of no rest and not giving the body time to adapt.
so be carefull when you do it! you probably allready know it!

We (me and my wife) already had one week at around 4000 m, and the trek would include camping one night at around 5000 m, and also going with a guide, so there wasn't much risk involved, but I can't say whether we would make it all the way to the summit. Probably, but hard to predict how the body would react. But I had a bad cold and a temperature above 38C, so it would be a very miserable climb had we not cancelled it.

Sunset as seen from our hotel room in Prague 2016-07-22. Single (cropped) frame from a video recorded with my new Sony FDR-AX53B 4K camera. I'm quite impressed with its performance. Now I need a 4K TV...

When I woke up this morning, I did not expect I would document a naval battle straight out of the old world. The Lady Washington (AKA "HMS Interceptor" of The Pirates of the Caribbean) exchanges fire with the Hawaiian Chieftain.



Added: Another green flash capture. cool

Cool. Was it possible to see it with your naked eyes?

Got one! I grew up with a b/w TV, one channel broadcasting a few hours a day. 4K is science fiction in comparison. We got a colour TV when I was around 8 years old, but still just one channel.
