The collection of larger than usual amounts of Arctic winter weather data in 2015 was due to two reasons: the Norwegian research vessel Lance was in the Arctic Ocean observing and collecting upper atmosphere meteorological data, and the frequency of observation and data collection was increased at some of the land - based observation stations around the Arctic.

A glaciologist rather than a biologist, he wanted to investigate a question critical to climate change: Do subglacial rivers and lakes lubricate the movement of ice over land — and might they somehow accelerate a glacier's flow into the ocean, triggering rapid sea level rise?

Land - based impacts were, on average, an order of magnitude more dangerous than asteroids that landed in oceans.

Water changes temperature more slowly than the air or land, which means the global ocean heat is likely to persist for some time.

These variations originate primarily from fluctuations in carbon uptake by land ecosystems driven by the natural variability of the climate system, rather than by oceans or from changes in the levels of human - made carbon emissions.

Typical ocean crust is just 4 miles (6 km) thick, roughly five times thinner than the crust that lies below land - based volcanoes.

Because the vast plateau at such altitudes absorbs a huge amount of solar radiation, the atmospheric layer above it in summer is much warmer than air at similar elevations over lower land or the oceans.

The effect was easier to see over water than land because, in general, the atmosphere above the oceans is relatively low in aerosols — tiny liquid or solid particles that float in the air.

What scientists discovered in 2014 is that since the turn of the century, oceans have been absorbing more of global warming's heat and energy than would normally be expected, helping to slow rates of warming on land.

That is because it is one of the few active rifts on land rather than in the depths of the old oceans.

Studies of past climate changes suggest the land and oceans start releasing more CO2 than they absorb as the planet warms.

June — August 2014, at 0.71 °C (1.28 °F) higher than the 20th century average, was the warmest such period across global land and ocean surfaces since record keeping began in 1880, edging out the previous record set in 1998.
