  • mountainous environments are living laboratories to study environmental change.

  • We're up here to document whether species air moving upward.

  • Mm hmm.

  • What we're finding in mountainous environments is that species from plants to animals to insects, they're actually rising in elevation.

  • In adapting to these thermal niches, we're trying to understand how climate change is impacting them.

  • I'm leaving a biology team to perform a comprehensive biodiversity survey of the Khumbu Valley.

  • What we're doing up here is trying thio understand what species are living up in these extreme environments by having our researchers go up higher to survey for things like plants, rodents and insects.

  • Comparing it to historical data from previous expeditions can give us ah lot of information about whether we can actually define how quickly these species are already moving.

  • Upwards of two types of surveys will be doing our water filtration, collecting water samples, doing things like turning over rocks, looking underneath and seeing what's there.

  • As a biologist, I focus in on the micro scale to really look for minute little details.

  • It's great working with Anton as a partner because he and step back and look at it from a more holistic understanding a background looking at the climatology off landscapes, and so that helps us understand better the organisms that were studying in the context of the landscape.

  • In terms of the ability to respond to climatic changes, different species have different capacities for responsible to use a local example.

  • Pure bred yaks can no longer live at the elevation where they used to live.

  • My whole family has lived in these mountains your whole life.

  • They have seen changes themselves, and they've lived through changes before we could see yaks down to an empty.

  • But now they're no longer able to tolerate the warming climate here, so they have to move about.

  • Thes small minute observations are actually very much important for any sort of scientific base understanding.

  • When we come up here to do our visual encounter, surveys will pick a piece of habitat that looks really good for species.

  • The soil will be well developed.

  • Will be plants will turn over rocks.

  • Well, that's a bristle.

  • Tail bristles.

  • Got him.

  • You got him when we find something will collect the animal in a plastic tube so we can photograph and measure it and document it.

  • He's got.

  • He's long sticking up.

  • The slope is incredibly unstable.

  • Rocks constantly in motion on their pebbles and rocks covering the surface.

  • But when you remove them, look underneath were finally basically.

  • Soils are developed.

  • There's masses.

  • There's little tassel grasses.

  • Basically, an ecosystem seems to actually be developing under the surface of this very unstable rocky substrate.

  • There's much more life appear than meets the eye.

  • At first glance, that's for sure.

  • When we get back to the lab will do analysis, combined with reaching out to local experts like entomologists and botanists to be able to identify all the species of the taxonomic level.

  • If there are any micro more organisms in here, they'll be throughout the solution.

  • What we're trying to do is gather as much information as possible to really understand.

  • How can we adapt to climate change, how people adapt to living up here?

  • How our species adapting?

  • Yeah, this climate change study doesn't end here.
