Sea levels are rising (ask the Mayor of Miami who has spent tax monies to raise road levels), we've had 15 of the hottest years eve measured, more precipitation is coming down in heavy doses (think Houston), we're seeing more floods and drought than ever before (consistent with predictions), the oceans are measuring warmer, lake ice in North America is thawing sooner (where it happens in northern states and Canada), most glaciers are shrinking, early spring snowpacks out west have declined since the 1950's, growing seasons are longer throughout the plains, bird wintering ranges have moved north, leaf and bloom dates recorded by Thoreau in Walden have shifted in that area, insect populations that used to have one egg - larva - adult cycle in the summer now have two, the list goes on and on.

The underlying cause of sea ice decline — atmospheric warming caused by high levels of CO2 in the atmosphere — has not changed.

This has been accompanied by warming of the ocean, a rise in sea level, a strong decline in Arctic sea ice, and many other associated climate effects.

http://www.sciencedirect.com/science/article/pii/S0959378012001215 They showed a low bias in IPCC evaluations for sea level rise, CO2 emissions, sea ice decline, permafrost melt and carbon feedbacks, rainfall intensity and northern hemisphere snow cover.

From a report described on the IPY (International Polar Year) site dated 2/25/09: «Snow and ice are declining in both polar regions, affecting human livelihoods as well as local plant and animal life in the Arctic, as well as global ocean and atmospheric circulation and sea level.»

For example, several references to climate change - induced sea level rise and its impact on military bases were removed, as were references to declines in Arctic sea ice.

• Global polar bear numbers have been stable or risen slightly since 2005, despite the fact that summer sea ice since 2007 hit levels not expected until mid-century: the predicted 67 % decline in polar bear numbers did not occur.

• Abundant prey and adequate sea ice in spring and early summer since 2007 appear to explain why global polar bear numbers have not declined, as might have been expected as a result of low summer sea ice levels.

Lukovich et al. (Centre for Earth Observation Science, U. of Manitoba); 4.4 to 4.5; Heuristic - Dynamics The absence of a strong and persistent sea level pressure high over the Beaufort in July together with the absence of spatial homogeneity in the springtime sea ice drift fields suggest that continued sea ice decline will be an artifact of increased temperatures and thermodynamic forcing rather than the considerable dynamical contributions seen in summer of 2007.

So Arctic sea ice decline doesn't raise sea levels, and it isn't directly linked to melts elsewhere in the world.

15 April, 2017 — Coastal glaciers in terminal decline as Greenland ice melts into the ocean and threatens to raise sea levels by the end of the century.

Abrupt summer sea ice decline has not affected polar bear numbers as predicted: even though sea ice levels dropped to mid-century levels in 2007, the expected decimation of polar bears failed to occur.
