In order to get funded published, climate academics have to pay homage to the global warming propagandists. This paper has interesting data showing less ice in the past, and then makes unsupportable conclusions about glacial retreat over the past 250 years.
“the highest percentage (>90?%) of Arctic GICs (glaciers and ice caps) smaller than present or absent in the middle Holocene at ??7–6?ka, probably reflecting more spatially ubiquitous and consistent summer warmth during this period than in the early Holocene. Following this interval of widespread warmth, our compilation shows that GICs across the Arctic began to regrow and summers began to cool by ?6?ka. Together, the Arctic records also suggest two periods of enhanced GIC growth in the middle to late Holocene from ??4.5–3 and after ?2?ka. The regional records show variability in the timing of GIC regrowth within and between regions, suggesting that the Arctic did not cool synchronously despite the smooth and hemispherically symmetric decline in Northern Hemisphere summer insolation. In agreement with other studies, this implies a combined response to glacier-specific characteristics such as topography and to other climatic forcings and feedback mechanisms, perhaps driving periods of increased regional cooling. Today, the direction of orbital forcing continues to favor GIC expansion; however, the rapid retreat of nearly all Arctic GICs underscores the current dominance of anthropogenic forcing on GIC mass balance.”

“Prof. T. G. Bonney has some very interesting things to say in “Nature” on what he calls “the shrinkage of the world’s ice mantle.” There has been a general retreat, he says, of the European glaciers since 1861.”
