The evidence is that glaciers are retreating, even in Norway.
Bobby, Grendel, and the Mechanic are not just wrong but also wrong-headed.
https://en.wikipedia.org/wiki/Retreat_of_glaciers_since_1850 Quote:Since 1980, a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous, so much so that some glaciers have disappeared altogether, and the existences of many of the remaining glaciers are threatened...
The retreat of mountain glaciers, notably in western North America, Asia, the Alps and tropical and subtropical regions of South America, Africa and Indonesia, provide evidence for the rise in global temperatures since the late 19th century.[4][5] The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions.
Global glacial mass balance in the last fifty years, reported to the WGMS and NSIDC. The increasing downward trend in the late 1980s is symptomatic of the increased rate and number of retreating glaciers.
Main article: Glacier mass balance
The mass balance, or difference between accumulation and ablation (melting and sublimation), of a glacier is crucial to its survival.[6] Climate change may cause variations in both temperature and snowfall, resulting in changes in mass balance. A glacier with a sustained negative balance loses equilibrium and retreats. A sustained positive balance is also out of equilibrium and will advance to reestablish equilibrium. Currently, nearly all glaciers have a negative mass balance and are retreating.[7]
Glacier retreat results in the loss of the low-elevation region of the glacier. Since higher elevations are cooler, the disappearance of the lowest portion decreases overall ablation, thereby increasing mass balance and potentially reestablishing equilibrium. If the mass balance of a significant portion of the accumulation zone of the glacier is negative, it is in disequilibrium with the climate and will melt away without a colder climate and or an increase in frozen precipitation.[8][9]
Methods for measuring retreat include staking terminus location, global positioning mapping, aerial mapping and laser altimetry.[8][10] The key symptom of disequilibrium is thinning along the entire length of the glacier. This indicates a diminishment of the accumulation zone. The result is marginal recession of the accumulation zone margin, not just of the terminus. In effect, the glacier no longer has a consistent accumulation zone and without an accumulation zone cannot survive.[9][11] For example, Easton Glacier in Washington state, U.S. will likely shrink to half its size but at a slowing rate of reduction and stabilize at that size despite the warmer temperature over a few decades. However, the Grinnell Glacier in Montana, U.S. will shrink at an increasing rate until it disappears. The difference is that the upper section of Easton Glacier remains healthy and snow-covered, while even the upper section of the Grinnell Glacier is bare, is melting and has thinned. Small glaciers with minimal altitude range are most likely to fall into disequilibrium with the climate.[9]
Middle latitude glaciers
... As with examples located in the tropical zone, virtually all the glaciers in the mid-latitudes are in a state of negative mass balance and are retreating.[10]
... In Norway, glacier studies have been performed since the early 19th century, with systematic surveys undertaken regularly since the 1990s. Inland glaciers have had a generally negative mass balance, whereby during the 1990s, maritime glaciers showed a positive mass balance and advanced.[25] The maritime advances have been attributed to heavy snowfall in the period 1989-1995.[25] However, reduced snowfall since has caused most Norwegian glaciers to retreat significantly.[25] A survey of 31 Norwegian glaciers in 2010 indicated that 27 were in retreat, one had no change and three advanced.[26] Similarly, in 2013, of 33 Norwegian glaciers surveyed, 26 were retreating, four showed no change and three advanced.[26]
Engabreen Glacier in Norway extended to within 7 m (23 ft) above sea level in 2014, the lowest altitude of any glacier in Europe.
Engabreen Glacier in Norway, an outlet glacier of the Svartisen ice cap, had several advances in the 20th century, though it retreated 200 m (660 ft) between 1999 and 2014.[27] Brenndalsbreen glacier retreated 56 m (184 ft) between the years 2000 and 2014, while the Rembesdalsskåka glacier, which has retreated 2 km (1.2 mi) since the end of the Little Ice Age, retreated 200 m (660 ft) between 1997–2007.[28] The Briksdalsbreen glacier retreated 230 m (750 ft) between 1996 and 2004 with 130 m (430 ft) of that in the last year of that study; the greatest annual retreat recorded on that glacier since studies began there in 1900.[29] This figure was exceeded in 2006 with five glaciers retreating over 100 m (330 ft) from the fall of 2005 to the fall of 2006. Four outlets from the Jostedalsbreen ice cap, the largest body of ice in continental Europe, Kjenndalsbreen, Brenndalsbreen, Briksdalsbreen and Bergsetbreen had a frontal retreat of more than 100 m (330 ft).[30] Overall, from 1999 to 2005, Briksdalsbreen retreated 336 metres (1,102 ft).[30] Gråfjellsbrea, an outlet glacier of the Folgefonna ice cap, had a retreat of almost 100 m (330 ft).[30] ...
