Arctic Sea ice data collected by DMI I then wrote “Sea Ice conditions years ago may not have been similar to the conditions of the last years, the study you reference contains no specific comparative analysis of to pre-satellite DMI Arctic ice area measurements and the abrupt significant fluctuations.

The climate of the Arctic is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, and nearly all parts of the Arctic experience long periods with.

Definitions. The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during Sea ice maximum is the day of a year.

“We present a time series of sea ice extent in the Russian Arctic based on observational sea ice charts compiled by the Arctic and Antarctic Research Institute (AARI). These charts are perhaps the oldest operational sea ice data in existence and show that sea ice extent in the Russian Arctic has generally decreased since the beginning of the.

The Northwest Passage (NWP) is the sea route to the Pacific Ocean through the Arctic Ocean, along the northern coast of North America via waterways through the Canadian Arctic Archipelago. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP).

The various islands of the archipelago are separated from one another and from the Canadian. Arctic sea ice has declined steadily since the s. However, the summer saw a dramatic drop in sea ice extent, smashing the previous record minimum set in by 20%.

This has been widely cited as proof of global warming. However, a popular mantra by climatologists is not to read too much into short term fluctuations - climate change is more concerned with long term trends.

A strong and persistent low pressure system over the central Arctic helped to inhibit ice loss during the summer months. The Arctic sea ice extent minimum in mid-September was 31% below the. Recent instrumental records show that during the past few decades, surface air temperatures throughout much of the Arctic have risen about twice as fast as temperatures in lower latitudes (Delworth and Knutson,Knutson et al., ).The remarkable reduction in Arctic Ocean summer sea ice in outpaced the most recent predictions from available climate models (Stroeve et al., Cited by: * A paper in the Journal of Geophysical Research found that the area covered by sea ice in the Arctic was declining by about % per decade, while the area covered by sea ice in the Antarctic was increasing by about % per decade.

Walrus radio-tracking in the Chukchi Sea USGS Alaska Science Center researchers attached 39 satellite radio-tags to walruses in the northeastern Chukchi Sea, July to track the movement patterns and foraging behaviors of walruses within areas of offshore sea ice.

Project Purpose: The retreat of sea ice beyond the continental shelf in the past seven years represents a step change in. Now that previous predictions of an ice-free Arctic Ocean have failed to materialize, the alarmists are extending their wolf cry to predict it will happen in or etc.

Such are the predictions of “climate scientists” for whom, it seems, computer models are their reality. Arctic sea ice melt is nothing new. This was the highest five-day period for April since Many locations set new high maximum (daytime) and minimum (nighttime) temperatures for the month.

Several stations across Denmark observed the earliest summer day, defined as days with a maximum temperature > °C (°F), in over 50 years on 19 April The most notable maximum. World of Change: Ice Loss in Glacier National Park. Shrinking since at least the early s, the ice cover in Glacier National Park is expected to keep declining until only insignificant lumps remain.

These images show changes to the park's ice and surrounding landscape since Land Snow and Ice Remote Sensing World of Change. Arctic Ocean sea ice proxies generally suggest a reduction in sea ice during parts of the early and middle Holocene (∼–10, years Before the Present) compared to present day conditions.

This sea ice minimum has been attributed to the northern hemisphere Early Holocene Insolation Maximum (EHIM) associated with Earth’s orbital cycles. Under frigid winter conditions, the Arctic’s floating lid of sea ice typically expands to a maximum extent in March.

But thanks to human-caused global warming, that maximum seasonal spread of the ice has been shrinking over the years — and this past March it reached the lowest level ever observed for the month. Ice thickness is only part of the story.

There is also the question of the areal extent of sea ice. This graph shows Arctic sea ice extent, based on satellite observation since Fig - Arctic sea ice extent [10] The total area of the Arctic Ocean is about 14 million sq.

Extreme cold events are generally described in terms of temperature, although wind, snow, and ice can compound the impacts of an extreme cold event (Figure ).

The actual temperatures that characterize a cold event vary regionally and seasonally, but the temperatures during such an event will be in the cold tail of the probability. The walrus (Odobenus rosmarus) is a large flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern walrus is the only living species in the family Odobenidae and genus species is subdivided into two subspecies: the Atlantic walrus (O.

Extent of Arctic sea ice passed a tipping point inaccording to research published in the February issue of The Cryosphere.

Indeed, studies of the past million years indicate a repeatable cycle of Earth’s climate going from warm periods (“interglacial”, as we are experiencing now) to glacial conditions.

Gedroyts, I. Gramberg, V. Saks, N. by:   There’s a lot more misinformation in Joe D’Aleo’s post at WUWT about the decline of Arctic sea ice than just the fake portrayal of Arctic regional temperature highlighted in the last post. To support his claim that Arctic sea ice decline is just natural variation, D’Aleo makes this claim: The temperatures in the arctic have indeed risen in recent years and ice has declined, bottoming.

The seasonal sea ice zone is defined as the area between the minimum and maximum seasonal ice limits plus the region of the ice margin that is significantly affected by the ice-ocean boundary.

This definition includes almost all of the Antarctic ice cover, the ice in the marginal seas around the Arctic and the ice cover overlying the shelves of Cited by: Fall and winter seasons have experienced the largest changes in surface temperature in connection with the loss of sea ice and resulting increased absorption of solar energy into the Arctic Ocean.

Future trends and Tipping points Whereas the precise nature tipping point/s ensuing from the confluence of numerous processes (Figure 2) remains little defined, the weakened boundaries between the Arctic and sub-Arctic zones (Figure 7) and the build-up of cold ice melt pools in the oceans fringing Greenland and Antarctica represent an initial stage in the development of a stadial : Sam Carana.

Ice Age conditions first appeared on the Earth about 45 million years ago with the appearance of permanent ice sheets in Antarctica. The other feature of this ice age climate was the sharp drop in the concentration of CO2 which dropped from several thousand ppm 50 million years ago to levels as low ppm as recently as 3 million years ago.China's seas cover nearly 5 million square kilometers extending from the tropical to the temperate climate zones and bordering on 32, km of coastline, including islands.
