Climate Change Facts – Arctic

The Arctic shows no sign of returning to being a reliably frozen region

 

Despite relatively cool summer temperatures, observations in 2017 continue to indicate that the Arctic environmental system has reached a “new normal”, characterized by long-term losses in the extent and thickness of the sea ice cover, the extent and duration of the winter snow cover and the mass of ice in the Greenland Ice Sheet and Arctic glaciers, and warming sea surface and permafrost temperatures.

 Highlights from 2017

The average surface air temperature for the year ending September 2017 is the 2nd warmest since 1900; however, cooler spring and summer temperatures contributed to a rebound in snow cover in the Eurasian Arctic, slower summer sea ice loss, and below-average melt extent for the Greenland ice sheet.

The sea ice cover continues to be relatively young and thin with older, thicker ice comprising only 21% of the ice cover in 2017 compared to 45% in 1985.

In August 2017, sea surface temperatures in the Barents and Chukchi seas were up to 4° C warmer than average, contributing to a delay in the autumn freeze-up in these regions.

Pronounced increases in ocean primary productivity, at the base of the marine food web, were observed in the Barents and Eurasian Arctic seas from 2003 to 2017.

Arctic tundra is experiencing increased greenness and record permafrost warming.

Pervasive changes in the environment are influencing resource management  protocols, including those established for fisheries and wildfires.

The unprecedented rate and global reach of Arctic change disproportionally affect the people of northern communities, further pressing the need to prepare for and adapt to the new Arctic.

Climate Change Facts – Antarctic

The West Antarctic Peninsula is one of the fastest warming areas on Earth

 

Some areas of the Arctic Circle are experiencing faster rising temperatures than the West Antarctic Peninsula.  However, since Antarctica is a big place, climate change is not having a uniform impact, with some areas experiencing increases in sea ice extent. Yet in others, sea ice is decreasing, with measurable impacts on wildlife. ASOC believes that understanding climate change impacts on Antarctica is a matter of critical importance for the world and for the continent itself.

THE ANTARCTIC AND CLIMATE

Local Antarctic effects of climate change are only part of the problem. Antarctica comprises two geologically distinct regions, East Antarctica and West Antarctica, separated by the great Trans-Antarctic Mountains but joined together by the all-encompassing ice sheet.

The presence of the high ice sheet and the polar location make Antarctica a powerful heat sink that strongly affects the climate of the whole Earth.

Furthermore, the annual sea ice cover around the continent, which seasonally reaches an area greater than that of the continent itself, modulates exchanges of heat, moisture, and gases between the atmosphere and ocean and, through salt rejection when it freezes, forces the formation of cold oceanic bottom waters that spread out under the world’s oceans.

Alterations to this system will affect climate all over the planet.

THE WEST ANTARCTIC ICE SHEET

Both the ice sheet and the sea ice are potentially subject to change in a changing climate; the ice sheet, in fact, may be changing now in response to past climate change.

The greatest threat to the inhabited world comes from the West Antarctic ice sheet (WAIS), which rests on a bed far below sea level and so may have the potential for rapid shrinkage. The Antarctic is so vast, remote, and difficult to monitor, however, and the physical behavior of the ice sheet so complex, that there is as yet no definitive demonstration (or disproof) of such change, even though a pronounced climatic warming is ongoing in one northerly portion of the continent.

The Antarctic ice sheet contains sufficient ice to raise world-wide sea level by more than 60 meters if melted completely. The amount of snow deposited annually on the ice sheet is equivalent to about 5 mm of global sea level, as is the mean annual discharge of ice back into the ocean. Thus, a modest imbalance between the input and output of ice might be a major contributor to the present-day rise in sea level (1.5–2 mm per year), but the uncertainty is large.

Antarctic species are dramatically impacted by climate as well. Krill often feed on algae underneath sea ice and populations have been declining around the West Antarctic Peninsula as sea ice has decreased.

Adélie penguin populations have been declining in recent years due to reductions in krill populations and changing weather conditions in their traditional nesting areas. Emperor penguins are highly vulnerable as well and are predicted to suffer when the world’s average temperature increases by 2 degrees Celsius.

Furthermore, a 2008 study has identified Antarctic toothfish as highly vulnerable to climate change. Climate change in Antarctica will thus have dramatic effects both globally and locally – and perhaps harm some of the world’s most beloved species.

World Ocean Observatory

The World Commission on the Ocean seeks to create an agenda for the sustainability of the oceans

 

In 1998, Mario Soares, former President of Portugal, organized the Independent World Commission on the Ocean, comprising leaders and experts from around to globe, to create an agenda for the sustainability of the oceans.

In the final report, The Ocean Our Future, Soares writes, “We need to forge a new ethico-political relationship between humanity and the oceans, a relationship with a political and juridical basis which creates an atmosphere of sharing and solidarity and which provides for a new universalism centered on knowledge of the oceans; a relationship capable of unifying the citizens of the world under one banner, a common, unique and irreplaceable asset: the sea which all the continents share.”

Among its many suggestions, the Report calls for an ocean observatory that “would serve as a focal point for bringing together relevant information from other sources official and unofficial, including intergovernmental, governmental and non-governmental institutions or networks.”

At the same time, “the Observatory would serve as an interactive virtual observation site for all ocean-related information on the World Wide Web, providing direct electronic links to all relevant (public and private) Internet sites.”

The World Ocean Observatory is the realization of that recommendation.

Homeward Bound- 1000 Women in STEMM

1000 Women of Science, Technology, Engineering, Math, & Medicine

 

What if men and women led our world in equal measure – would our world and the decisions we make on behalf of future generations be different? Would we be more collaborative, inclusive, more legacy minded and more trustworthy with assets, people and money?

We believe that supporting women in science to significantly improve their clarity, confidence, shared vision and strategic capability will enhance their opportunity to take up leadership roles globally and to proactively contribute to a sustainable world both individually and collectively.

In doing this, we aim to create a new way of leading better suited to the world we are now living in, with a greater focus on the concept of a ‘global home’ – led with integrity, a drive for results, an ability to motivate others, a deep care for relationships and the will to collaborate towards this shared ambition.

Over ten years, we will build a global collaboration of 1,000 women with scientific backgrounds.  They will be visible, collaborative, networked and impacting the decisions made in many quarters for the greater good.

This is a small but meaningful contribution to a very complex challenge we all face.

History of Female Trappers in Svalbard, Norway

The Story of Wanny Woldstad

 

(Image: The Norwegian Polar Institute)

Winter trapping had long traditions as an activity for men. The few women that participated did so more as housekeepers for their husbands than as actual trappers. Wanny Woldstad from Tromsø was an exception.

Wanny was a taxi-driver in Tromsø, in mainland Norway, in the 1930s. She often listened to stories told by the trappers who returned from Svalbard with a profit. They liked to spend some of it going to Ølhallen, the Mack brewery’s bar, by taxi.

In 1932 she was asked to join an expedition to Svalbard with Anders Sæterdal and she immediately accepted. “In two-three days I was converted from a taxi-driver in Tromsø to a female trapper on the way to Svalbard onboard Maiblomsten”.

In the beginning many of the experienced trappers were skeptical to her participation and abilities as a trapper in the harsh conditions. At 157 cm tall, she was a small woman, but she showed great drive and eagerness to learn and proved that this lifestyle was right for her.

The following two years she brought her two sons to Hornsund – Alf and Bjørvik Jacobsen – who later became experienced trappers in Svalbard.

Wanny used Hyttevika as her main station. Isbjørnhamna, close to the site of today’s Polish Research Station, was the closest satellite station – it was near here that Wanny shot her first bear, on 12 December 1932. Fuglefjell (Gnålodden) was her second satellite station.

In Hyttevika there was a contraption set up to catch polar bears called Signalen (the Signal):

 “…The Signal is a simple but highly effective contraption: A stick of about 2 meters is planted in the ground about 60-70 meters from the house. A blubber bait is attached by a strong string halfway up the stick. The string is led over a reel at the top of the stick and then over to the house and through a hole in the wall into the innermost room. Here the string is attached to a wooden stick stuck into the hole from the outside. A few empty milk-cans are hung on the stick inside the room, constituting the alarm.” (Woldstad 1956).

When the Signal went off she sneaked silently to the loophole, rifle in hand, to shoot the bear. Because of The Signal the dogs had to sleep indoors to avoid scaring away approaching polar bears. 

Wanny was an exceptional woman, participating in shooting competitions and being Tromsøs first female taxi driver – with her own car in the 1920s.

She eventually ended up spending several winters with the experienced trapper Anders Sæterdal. The experiences she made is covered in her book “The first woman trapper on Svalbard”.
