The World Glacier Monitoring Service, based at the University of Zurich in Switzerland and with partners in 30 countries, has been compiling data on changes in glaciers over the last 120 years. And it has just compared all known 21st century observations with data from site measurements, aerial photography and satellite observations and evidence from pictorial and written sources. Altogether, the service has collected 5,000 measurements of glacier volume and changes in mass since 1850, and 42,000 records of variations in glacier fronts from records dating back to the 16th century.

And the evidence is clear: the glaciers are in retreat, worldwide, and the retreat is accelerating.

"Now who do you sponge off of?"

Don't harsh my panic buzz.

Call it Crazy says

1 Degree rise in C equals a 1.8 degrees rise in F

Finally, something we agree on.

1.8 degree rise F over 135 years is a big nothingburger!

I wouldn't blindly extrapolate the past 135 years to the next 100 years.

Are those nothing fries seasoned or waffle cut?

Nobody is blindly extrapolating. The real trend didn't kick in in a big way until about 40 years ago. The different models vary the degree to which future increases of carbon in the atmosphere cause further temperature increases. Even if you believe that it's only correlation (so far) and that causation (from carbon) is very much unproven, you can not intelligently argue against the risk. How high would the probability need to be that carbon in the atmosphere is the cause, and how high would the probability that the projections are accurate need to be, in order for you to agree the risk is high enough that mankind should try to agree to move together at a reasonable pace towards clean forms of energy ?

There's really nothing for sane people to be arguing here, given what climate scientists are telling us.

The World Glacier Monitoring Service

Which Libbie organization funds them??

(Oh, I found it on their site:

United Nations Environment Programme (UNEP)

United Nations Educational, Scientific and Cultural Organization (UNESCO)

Ahhh, the same people who published the IPCC report.... Hmmmmm...)

This is your well thought out highly organized well documented response showing that glaciers are actually not retreating? Well in all fairness it's probably the best you can do.

Really?? Why did you post this chart?

There is a large difference between blindly extrapolating and using data to model behavior and then using the model to predict the future.

well lets see..
120 years of samples over 4.543,000,000 years of countless earth temperature cycles.
A sampling time span of 0.000002641% since the earth's been around.
Damn...must be time to shit donuts and tax the rich...

Humans are an adaptable species.
Why do you hate evolution?

he different models vary the degree to which future increases of carbon in the atmosphere cause further temperature increases.
