It isn’t the first time a global warming study has been ironically halted in its tracks.
The following citations of research cruises is an example of cherry-picking

yet they absolutely know how the climate will behave over the next 100 years
This is a common and misleading argument that has been dispelled many times. Climate projections don't presume to predict exactly what will be happening and where at any given time, but instead describe the average climate (or the statistics of weather). A decrease in Arctic sea ice extent overall is a well-known feature of climate change, but within that, variability in regional ice concentration is expected.

different from their predictions
The linked article is not about predictions made for Arctic sea ice

called Arctic amplification
in which Arctic surface air temperatures warm at a faster rate than global average temperature

could occur by 2030, although many scientists say it may not happen for a decade or two after that.
2030 is on the early side of ice-free predictions but definitely not out of the realm of possibility

How long it will take is unclear
In part due to large uncertainties in the timescale of melting of the great land ice sheets of Greenland and Antarctica (see what @bphorton said)

some political conservatives
This is in the context of decades of industries sowing doubt about scientific evidence of human-caused global warming. e.g. http://www.ucsusa.org/publications/got-science/2016/got-science-may-2016#.Wc1bUNOGNN0

the oceans are rising at an accelerating pace
Because more than 90% of the energy added to the climate system is being stored in the ocean, causing sea level rise through thermal expansion. "Ocean warming dominates the increase in energy stored in the climate system, accounting for more than 90% of the energy accumulated between 1971 and 2010 (high confidence)." -IPCC AR5 Summary for Policy Makers

You can think of global warming as one type of climate change.
It is also worth noting that global warming refers to global average temperature rising, but this does not necessarily mean that all locations across the globe are warming at all times.
