It is 7 kilometres (4 miles) long and 200 metres (656 feet) deep.\u003cbr/\u003eVincent explains that samples are obtained by boring into the snow on different parts of the glaciers. \u003cbr/\u003eHe says that these samples are taken in the same locations during different expeditions to ensure that comparisons over the years are as accurate as possible. \u003cbr/\u003eThese observations have been made for the past 50 years, building up a clear picture of the evolution of climate over time. \u003cbr/\u003eA core sample is obtained by boring into the snow - various measurements are then recorded so the scientists can later determine the glaciers' mass balance. \u003cbr/\u003eVincent says that the scientific community is interested in their observations as it is a good indication of climate change. \u003cbr/\u003eClimate change is blamed for causing variations in both temperature and snow fall and this in turn is believed to have an impact on the mass balance. \u003cbr/\u003eVincent says that glaciers fascinate the public not only for their stunning natural beauty but also because they often serve as a stark reminder of the effects of global warming as their shrinking can be seen with the naked eye. \u003cbr/\u003eThe Mer de Glace was once visible from the ski resort of Chamonix, but nowadays can barely be glimpsed from below. \u003cbr/\u003eIn March 2008 the United Nations Environment Programme published a study which found that glaciers are shrinking at record rates and many could disappear within decades. \u003cbr/\u003eScientists measuring the health of almost 30 glaciers around the world found that ice loss reached record levels in 2006, the U.N. agency said.   \u003cbr/\u003eOn average, the glaciers shrank by 4.9 feet in 2006, the most recent year for which data are available.  \u003cbr/\u003eThe most severe loss was recorded at Norway's Breidalblikkbrea glacier, which shrank 10.2 feet in 2006, while Chile's Echaurren Norte glacier was the only one to grow slightly thicker.  \u003cbr/\u003eThe study was based on the findings of the World Glacier Monitoring Service, a Zurich-based body. \u003cbr/\u003eThe study found that glaciers lost an average of about a foot of ice a year between 1980 and 1999. \u003cbr/\u003eBut since the turn of the millennium the average loss has increased to about 20 inches.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false' aria-label='Read more description'
