Not exact matches

Given that we now have several years more data, we can essentially «test» the IPCC predictions and we arrive at the conclusion (i.e., message 1) that the climate system is tracking the «worst case scenario» (or worse in the case of ice melt and sea - level rise) presented by the IPCC.

Because ice sheets contain so much ice and have the potential to raise or lower global sea level so dramatically, measuring the mass balance of the ice sheets and tracking any mass balance changes and their causes is very important for forecasting sea level rise.

They are also swollen by melting glaciers, ice caps and ice sheets: Greenland's ice is on track to melt completely, which will eventually raise the sea level by about seven metres (23ft).

Satellite tracking has shown that the Pine Island Glacier, one of Antarctica's largest ice streams, is accelerating and thus contributing a growing share of the melt water raising sea levels worldwide.

Global sea ice (Arctic plus Antarctic) continues to track at record low levels in the satellite record, but the deviation from average has moderated compared to what was observed in November.

Losing land ice means sea levels will rise, and if we lose a lot of ice in Greenland and Antarctica — which we are very much on track for doing — sea levels could rise several meters.

Nevertheless, improvements in ice - sheet models over recent decades have led to closer agreement with satellite observations, keeping track with their increasing contribution to global sea - level rise.

The report tracks patterns, changes, and trends of the global climate system, including: greenhouse gases; temperatures throughout the atmosphere, ocean, and land; cloud cover; sea level; ocean salinity; sea ice extent; and snow cover.
