Sentences with phrase «land glaciers which»

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.

This happens as the ocean undermines the land - sitting glaciers right at the waterline causing the glaciers to detach from the bedrock on which they are sitting.

These wildfires release soot into the atmosphere, which accelerates the rate of melting of glaciers, snow and ice it lands upon, which can lead to less reflectivity, meaning more of the sun's heat is absorbed, leading to more global warming, which leads to even more wildfires, not to mention greater sea level rise, which is already threatening coastal areas around the world.

An estimated 150 glaciers blanketed the land in 1850, most of which still existed in 1910 when the park was established.

For example, as a result of ice melting on land, such as from glaciers and ice sheets, as well as thermal expansion of the ocean, we have seen sea level rise 3.4 millimeters per year from 1993 - 2015, which puts coastal communities at risk of flooding and infrastructure damage.

Among the most comprehensive surveys ever done, it looked at floating glacier - ice shelves, which are connected to the land - based glacier from which they flowed, and tidewater glaciers that rest on land and break off into the ocean when they reach the water.
