the very idea that the highest part of the planet has bean impacted by human activity ought to be a real wake up call for everybody.

We're working close to the top of Everest.

The big goal off this National Geographic project is to collect scientific information about climate change and how much lay shires were changing.

The size they are is a consequence of their environment.

Climate change is the most important security issue of the 21st century.

It's not just a change in temperature as a change in precipitation.

Flooding, storm patterns, air quality, water quality.

I just like the Himalayas, have experienced changes that are higher than the average global rate.

My involvement has Bean primarily being able to answer.

A very big question is what is going on today, something that's part of a natural cycle or not?

You do that by getting as long a record is you can and seeing if what's going on today is markedly different than what's happened in the past.

Yeah will be collecting ice cores, which capture past temperature precipitation, storm patterns and biological productivity layer by layer going back through time.

Ice cores are the most robust tool that we have for looking at past climate.

My role here is collect ice core and snow samples on the way up from Khumbu Glacier across Cuba.

If it's possible, E, we're going to use drill that you can compare to to with teeth on the end things scraping ice when it filled tube bottom part of the drill will collect the ice core itself.

I don't care how fantastic acclimate you are.

Without the Sherpas, all of this equipment wouldn't get up to the various camps.

We're going to depend heavily on them to get the ice scoring.

It'll be a real stress on everybody at 80 m in south call Morning, guys.

13 m per second to 70 one afternoon Negative.

It sounds like you guys had a bit longer time in the icefall and obviously getting up to camp two in the heat than we had anticipated.

Our camp for south cold going three minutes from here.

So we try to use all the entire time to collect as much as possible because we're limited by oxygen on temperature.

So I think the maximum you can stay there about two hours no more.

This one is about 8000 m above sea level.

We've lived in a dream world for a while.

We've assumed that the way we have evolved in the last 100 years is a good way for humans to live.

My biggest hope for this expedition is that what we find here will awaken people, even Mawr.
