\n Huge white tarpaulins help protect the Presena glacier from melting during summer in the Italian Alps

A vast tarpaulin unravels, gathering speed as it bounces down the glacier over glinting snow. Summer is here and the alpine ice is being protected from global warming.<\/p>\n

In northern Italy, the Presena glacier has lost more than one third of its volume since 1993.<\/p>\n

Once the ski season is over and cable cars are berthed, conservationists race to try and stop it melting by using white tarps that block the sun’s rays.
\n“This area is continuously shrinking, so we cover as much of it as possible,” explains Davide Panizza, 34, who heads the Carosello-Tonale company that does the work.
\nFrom around 30,000 square metres (36,000 square yards) covered in 2008 when the project began, his team now places 100,000 square metres under wraps.
\nThe coverings are “geotextile tarpaulins that reflect sunlight, maintaining a temperature lower than the external one, and thus preserving as much snow as possible,” he told AFP.
\nOn the border between the Lombardy and Trentino Alto Adige regions, workers unroll the sheets in long strip<\/a>s, covering an area at an altitude of 2700 to 3000 metres (8,800-9,800 feet).
\nThey move methodically down the mountain under clear blue skies to pull the coverings taut, and sew them together to ensure warm drafts do not slip underneath. Bags of sand then act as anchors against the wind.<\/p>\n

\n It takes six weeks to install the tarps, and another six weeks to remove them before winter sets in again

Once in place, the sheets, which measure 70 metres by five metres (230 by 16 feet), are hardly distinguishable from the packed white snow beneath.
\n“There are glacier cover systems similar to ours on a few Austrian glaciers, but the surface covered by the tarpaulins is much smaller,” Panizza said.
\nThe Austrian-made tarps cost up to 400 euros ($450) each and it takes the team six weeks to install them\u2014and another six weeks to remove them before winter sets in again.
\nFranco Del Pero, 48, leads the operation and says technological improvements mean contemporary tarps protect better than earlier versions.
\n“When we remove them in September and we see that they did their job, we feel proud,” he says.<\/p>\n
