@wolfgang59 saidIceland sits on top of the Atlantic ridge and there is a constant flow of molten magma from the mantle to the surface. Iceland is the most actively volcanic area in the world with eruptions occurring on average every four years and although the land mass is relatively small a staggering 33% of all lava of the Earth’s lava flows flow through is volcanic systems. The volcanic eruptions can cause devastating lava flow damage with millions of tons of hot ash being ejected into the atmosphere; locals and visitors as advised to monitor volcanic activity as well as atmospheric conditions as eruptions in the highlands can deposit noxious gasses and dust across any part of the island.This monument is to acknowledge that we know
what is happening and what needs to be done.
Only you know if we did it.

Do you think it possible that other factors other than just global CO2 levels may be in play here?
@divegeester saidI'm sure there are hundreds of scientists in Iceland awaiting your insight.

Or maybe they have noticed the volcanoes too?
@patzering saidFascinating ... where can I find out more?
The planet gets hotter and colder.
It's a cycle.
We've had ice ages and periods of time have been extraordinarily hot.
Up and down for billions of years.
@wolfgang59 saidThis thread was quite interesting “and so far without any silly off topic snarking. I think it is going quite well - don't you?”

@wolfgang59 saidMaybe the same place you can provide specific evidence of a correlation between the rate of the loss of ice on this glacier which sits atop a volcano, and the rate of global warming.

What I’ve read indicates that this glacier has been losing ice since the first decades of the last century. Now we know that CO2 levels have been rising since the industrial revolution but is there evidence that the ice loss on this specific glacier, since the early 1900s, is caused solely by that. Bearing in mind it sits on top of an (albeit relatively dormant) volcano in the most volcanic lava spewing region of the world.
I’m not saying the evidence doesn’t exist; I’m just asking you to get some from some of the “hundreds of scientists” on Iceland who are apparently awaiting my insights.
Can I say in thread parenthesis that I totally accept that climate change is occurring due to increased CO2 levels. I also accept that it is probably species threatening due to the negative cascade of biological and agricultural impacts. I am in no way a ‘climate change denier’.
I prefer the truth and this volcanic glacier story with plaques and memorials and lamenting and ceremonies and pilgrimages smells of hand-wringing media- fuelled politicised storifying.

High hopes for this thread were disappointed soon after second post.
Nice derailing.

@great-big-stees saidthe volcanoes in iceland have melted all the derailleurs
Speaking of derailing. Does anyone know where I can find, an inexpensive, Derailleur for my 1976 Peugeot bike?

@great-big-stees saidMy old neighbor was bike-crazy. He bought and sold them just for fun. I recall that his primary source for rare parts and accessories was Craig's List. Good luck my man. That bike is a classic!
Well I am trying to do my bit to help Green the land by getting my bike back in working, in more than 1 of it's 10 gears.
Here's a quickly googled link that might help:
