How Does Climate Change Affects Glaciers

1371 words - 6 pages

Intro

Glaciers have been around for millions of years and with the arrival of global warming there being threatened and challenged by warmer weather conditions and many of them have already melted and this has happened before but there has normally been a ice age and the glaciers just grow back but with the arrival of global warming the chance of a ice age has gotten much smaller and so has the chance of the glaciers that have melted to grow back or for new glaciers to form. For my global perspective I will be looking at the whitechuck glacier in Washington that from about 1970 to 2011 has retreated about 2 km and has lost half it's surface area. For my local perspective I will be doing ...view middle of the document...

the entire north branch of the glacier melted in 2001 and as you can see in the picture it is much much smaller than it was in the 1980s and there is a few small lakes one big lake where the glacier used to be and in 50 years if it carries on melting the whole area will just be a lake.the whitechuck glacier is found in washington u.s. the net loss of this glacier over the last 20 years is estimated at up to 32% and this glacier started to retreat about 80 years ago and has lost about 50% of its area so this proves that just recently the rate of retreat has gotten much bigger and this has happened because of global warming which is a fairly recent thing and has had a major increase that started about 25 years ago and i think that this is why the glaciers in the world have been melting so fast in recent years.

the whitechuck glacier is one found in a prime location for hiking mountaineering and climbing and if this glacier was to melt the activities would lose a lot of their beauty and wow factor and thus they would lose popularity and their wouldn't be as much point in doing the activities because you won't get the same science of achievement if you're not seeing anything breathtaking like a glacier so the whitechuck glacier is a big part of not just beauty in the area but in activities as well. and this all proves that it would be a tragedy if this magnificent glacier melts like others have, a study was done on 47 glaciers in close proximity to the whitechuck and 5 of them have melted away completely in the last 40 and in 2005 42 of the glaciers are retreating and 5 are not moving but there are none that are growing6 and the whitechuck glacier will probably last another 50 years before it completely disappears forever.

the fox glacier is located on the west coast of new zealand and is one of the most accessible glaciers in the world and also one of the fastest moving in the world with it shaped with a funnel and the top pressuring the snow at the bottom and because of their traits is an awesome glacier. the fox glacier was also one of the fastest glaciers to react to climate change only taking about 5 to 10 years to react and in 1900’s reached 15 km down the valley8 and has grown back half a km since 1980 where it was 12.5 km8 and now it is 13 km long8 but has diminished in height mass and width8 and the rate of retreat is expected to grow . the glacier is...
