The Chinese government is sending a team of scientists to the top to resurvey the mountain after reports of the snow cap slowly melting due to climate change.
Wow, this is really hitting home if it is found that Mount Everest is shrinking due to climate change. Guess we really have to do something if the effects start to appear everywhere more visibily around the world...

I reckon it'll probably still be on the big side even without the extra metre or two.

Presumably Mount Everest is shrinking due to erosion too?

India is still pushing it upwards too....just at a slightly slower rate than the erosion

Well their you go. I presume relaxation of the Tibetan Plateau probably has an effect too.

mt everest is in the himalayas.

the himalayas are a mountain range are on a constructive plate margin, ie 2 tectonic plates are smashing into each other and causing the crust to be forced upwards.

due to continual motion of the 2 tectonic plates together, mt everest will always continue to grow, but at a slow rate.

God, it's hardly an achievement to climb it now, is it?

I thought the rate was less than that of erosion?

I think the article is trying to imply that the increase in melting has increased the rate of erosion....and they might be right - but there's no way to record the erosion rates at such a remote location over the last 100-200yrs *and* take into account the varying rates of uplift so the theory/implication is pretty unprovable IMO.

But yeah - everest (and the whole of the himalayas) has been eroding faster than it's been uplifted for a fair old while now....

"The uplift continues even today at a measurable 10 meters every hundred years. Mount Everest has itself risen 8.2 meters in the last 100 years."

Not sure if that's excluding or including erosion...and given that noone has ever really agreed on how high the bloody thing is I don't know if I'd stake much on the accuracy of a change in hight of 0.1% over 100 yrs

Apparently, there was a science documentary on not so long ago that said Britain had mountains taller than Mount Everest, millions of years ago.

"The snow-covered mountain top is believed to have declined by 1.3 metres to 8,848 metres, according to state media reports"

Says it all really - who'd trust the Chinese state media?
