No one disputes global temperatures have been rising since the little ice age low points of the mid-1650's, when these very same glaciers were increasing and crushing villages and churches — PREVIOUSLY retreating before that when these same churches and villages were built in mountain valleys, and when Andean children were being buried on dry ground in front of retreating Andean glaciers!

When ice breaks off the Pine Island Glacier, he said, more ice can flow in faster from the mountains above — ice that will eventually wind up contributing to sea level rise.

You can't fake spring coming earlier, or trees growing higher up on mountains, or glaciers retreating for kilometres up valleys, or shrinking ice cover in the Arctic, or birds changing their migration times, or permafrost melting in Alaska, or the tropics expanding, or ice shelves on the Antarctic peninsula breaking up, or peak river flow occurring earlier in summer because of earlier snowmelt, or sea level rising faster and faster, or any of the thousands of similar examples.

The authors of the new paper said their goal was to challenge what had become orthodoxy about the mountain — that rising temperatures were eating away at the ice — and to present an argument for a different mechanism.

While worries about rising sea levels are focused on the massive ice sheets of Greenland and Antarctica, the loss of small mountain glaciers comes with its own consequences.

The permafrost that helps hold the state's mountain peaks together is also thawing rapidly, leading to a rise in the number of giant rock and ice avalanches.

A well - known example of this is the melting of land - based ice, which is contributing to sea - level rise (and adding to the effects of thermal expansion of the oceans), with implications for low - lying areas far beyond the polar and mountain regions where the melting is taking place.

Until recently, the contribution of ice sheets to sea - level rise remained unknown and is still debated, but the current acceleration of sea - level rise is attributed to heating of the oceans and melting of land glaciers which is supported by measurements of ocean temperatures and the behavior of mountain glaciers, the vast majority of which are retreating or exhibit signs of instability.
