Students should try to understand the scientific evidences critically. Build up analytical understanding to focus the evidences in their own individual assignments. 10 years ago melting rate was 1/3 current rate. 37 miles in past 150 years, and it getting faster, twice as fast as 5 years ago. All glaciers south of arctic circle melting faster. Greenland losing 20% more ice than it is gaining each year. glaciers moving faster towards sea- effect of meltwater warmer av. Temps creates large meltwater pools, drip down through cracks sea level rise in past decade ~0. 5 , and increasing quickly in past 5 years. Antarctica 11x more ice than greenland expansion- builds up in cracks because can"t drain from cracks.
