Freezing rain hit Seattle on Friday, the most significant ice event in
the region in at least a decade.
"Stay at home if you can," the authorities pleaded. People didn't listen.
The roads and sidewalks, though much more empty than usual, were scenes
of chaos.
One video shows a car sliding down the street and crashing into several
cars.
During the day, the Washington state patrol responded to 253 accidents
in King County alone.
By Friday afternoon, UW Medicine hospitals had reported about 70
icing-related injuries, mostly from people who slipped and fell.
Museums, theaters, libraries, zoo, aquarium: everything is closed.
Medical appointments have moved online.

/*Can geoengineering fix the climate? Hundreds of scientists say not so
fast*
The Biden administration is developing a controversial solar
geoengineering research plan to the dismay of many experts
As global heating escalates, the US government has set out a plan to
further study the controversial and seemingly sci-fi notion of
deflecting the sun’s rays before they hit Earth. But a growing group of
scientists denounces any steps towards what is known as solar
geoengineering.
The White House has set into motion a five-year outline for research
into “climate interventions”. Those include methods such as sending a
phalanx of planes to spray reflective particles into the upper reaches
of the atmosphere, in order to block incoming sunlight from adding to
rising temperatures...
- -
*Three potential methods of solar geoengineering*
*Stratospheric aerosol injection*
Airplanes release tiny aerosol particles that reflect light back
into space.
*Cirrus cloud thinning*
The least understood method, seeding thin cirrus clouds in the upper
troposphere
with ice nuclei could reduce their lifespan and increase cooling.
*Marine cloud brightening*
Boats release aerosol particles that increase the reflectivity of
low cloud
- -
This prospect horrifies opponents of solar geoengineering. An open
letter signed by more than 380 scientists demands a global non-use
agreement for SRM; it also says that growing calls for research in this
area are a “cause for alarm”, due to an unknown set of ramifications
that will have varying consequences in different parts of the world and
could scramble “weather patterns, agriculture and the provision of basic
needs of food and water”...
- -
The debate over how much we should meddle with the climate is likely to
intensify as the fallout from global heating worsens. For now, opponents
won’t back down. To Biermann, solar geoengineering should be considered
by governments as being akin to landmines or biological weapons and
blacklisted internationally.
“This is just another one on this list,” he said. “People talk about the
freedom of research, but you don’t have the freedom to sit in your back
yard and develop a chemical bomb.”

/[Open Letter Solar Geoengineering Non-Use Agreement ]/
*We Call for an International Non-Use Agreement on Solar Geoengineering...*
- -
In sum, an International Non-Use Agreement on Solar Geoengineering would
be timely, feasible, and effective. It would inhibit further
normalization and development of a risky and poorly understood set of
technologies that seek to intentionally manage incoming sunlight at
planetary scale. And it would do so without restricting legitimate
climate research. Decarbonization of our economies is feasible if the
right steps are taken. Solar geoengineering is not necessary. Neither is
it desirable, ethical, or politically governable in the current context.
Given the increasing normalization of solar geoengineering research, a
strong political message to block these technologies is required. An
International Non-Use Agreement on Solar Geoengineering is needed now.

Soon the Arctic will be ice-free in summer. While many are concerned
about the consequences for the global climate, countries like Russia and
the US, as well as China and Canada see an ice-free Arctic as an
opportunity, offering everything from new trade routes to mineral
resources and tourism.
In two episodes, this documentary reports on a region of the world that
is changing dramatically because of climate change, affecting the lives
of the people who make their home in the Arctic. The film team
experiences first-hand what it means to live at the mercy of the forces
of nature in this inhospitable region, which makes for an adventurous
and frightening journey.
In the first part of the documentary, they fly low over the fascinating
icy landscape of Greenland, filming the fjords and mighty glaciers of
the loneliest places in the world. The current Arctic thaw, however, is
felt far beyond this lovely, isolated place. Progressing faster here
than in the rest of the world, climate change is moving the Arctic into
the focus of global politics. Littoral states and world powers are
fighting for influence here. At the heart of their interest: access to
mineral resources and new transport routes. Because, as the ice melts,
new, shorter shipping routes are opening up. Is a new conflict looming
at the North Pole?
And how do the people in the far north experience the change in their
environment? The film team travels through the northern reaches of the
US, Canada, Greenland, Norway and Russia. The journalists experience the
wonder of nature in these regions and meet people who have adapted over
centuries to life in these cold, inhospitable realms. Now, they face a
new struggle, as global power players swoop in.
In Alaska, the camera team meets fishermen who have been driven from
American fishing grounds near the Bering Strait by Russian fighter
planes and warships. The fishermen are demanding that their government
provide a greater military presence in the region to protect their
interests.
The region has been the scene of a long-term dispute over water
ownership. For the US, the Northwest Passage counts as international
waters, while Canada considers it national territory. The conflict over
the Arctic could soon escalate. Because scientists are certain: In a few
decades, the Arctic will be ice-free in summer.

This is the place for scientific information, latest news and research
as published in peer reviewed journals.
Today, I did decide to do a detailed examination of this paper that was
featured in the last video. The paper is simply too important to not do
a deep dive.
This will be the only video I will post for the next 2 weeks. Because it
is a long video, I want to make sure people have a chance to watch it
all. I realize that not everyone will have the time to watch this entire
video in one sitting. If one wishes to watch say about 20 minutes at a
time, that's fine. This is why this will be the only video for the next
2 weeks. People will be able to see it all at a comfortable pace and
perhaps view the video or certain sections several times.
I have included chapters so if you wish to go to certain places in the
video and use these locations to pick up where you left off or wish to
view again.
Upcoming videos include my comment on the snow crab industry situation
here in Alaska.

*Nordic Seas Heat Loss, Atlantic Inflow, and Arctic Sea Ice Cover Over
the Last Century*

Lauvset, Clemens Spensberger, Andreas Born, Tor Eldevik, Helge Drange,

First published: 09 December 2021

*Abstract*
Poleward ocean heat transport is a key process in the earth system.
We detail and review the northward Atlantic Water (AW) flow, Arctic
Ocean heat transport, and heat loss to the atmosphere since 1900 in
relation to sea ice cover. Our synthesis is largely based on a sea
ice-ocean model forced by a reanalysis atmosphere (1900–2018)
corroborated by a comprehensive hydrographic database (1950–), AW
inflow observations (1996–), and other long-term time series of sea
ice extent (1900–), glacier retreat (1984–), and Barents Sea
hydrography (1900–). The Arctic Ocean, including the Nordic and
Barents Seas, has warmed since the 1970s. This warming is congruent
with increased ocean heat transport and sea ice loss and has
contributed to the retreat of marine-terminating glaciers on
Greenland. Heat loss to the atmosphere is largest in the Nordic Seas
(60% of total) with large variability linked to the frequency of
Cold Air Outbreaks and cyclones in the region, but there is no
long-term statistically significant trend. Heat loss from the
Barents Sea (∼30%) and Arctic seas farther north (∼10%) is overall
smaller, but exhibit large positive trends. The AW inflow, total
heat loss to the atmosphere, and dense outflow have all increased
since 1900. These are consistently related through theoretical
scaling, but the AW inflow increase is also wind-driven. The Arctic
Ocean CO2 uptake has increased by ∼30% over the last
century—consistent with Arctic sea ice loss allowing stronger
air-sea interaction and is ∼8% of the global uptake.
Key Points
Nordic Seas heat loss dominates variability and mean Arctic Ocean heat loss
Atlantic water volume and heat transport has increased over the last
century consistently with increased wind forcing and heat loss
Ocean heat transport anomalies affect Greenland melting, Arctic sea ice,
water transformations, and Arctic CO2 uptake
*Plain Language Summary*
The major flow to and from the Arctic Ocean occurs across the
Greenland-Scotland Ridge. The inflow is mostly warm Atlantic Water
(AW) flowing northwards and cooling gradually. After completing
different loops within the Arctic Ocean, portions of this water
eventually flows south as cold freshened polar water at the surface
and cold, dense overflow water at depth. We review and synthesize
how the AW cooling evolved over the last century in relation to the
Arctic sea ice cover. In the mean 60% of the heat loss occurred in
the Nordic Seas, 30% in the Barents Sea, and only 10% in the Arctic
seas further north. Arctic sea ice decrease the last century created
more open water and permitted stronger ocean heat loss. The ocean
volume and heat transport also increased, consistently with
increased heat loss, and increased wind forcing. Ocean temperatures
have generally increased in many areas during the last 50 years, and
on Greenland this drove the retreat of marine-terminating glaciers.
Variability in ocean heat loss to the atmosphere was primarily
driven by Cold Air Outbreaks and cyclones in the Nordic and Barents
Seas, and explain variability in Arctic Ocean CO2 uptake, being ∼8%
of the global uptake.

/*December 26, 2014*/
December 26, 2014:
The New York Times reports:
"Trying to write a complicated formula to cut carbon emissions, the
Environmental Protection Agency thinks it has found a magic number: 5.8.
"The agency is trying to complete a rule governing carbon emissions
from power plants, and among the most complicated and contentious
issues is how to treat existing nuclear power plants. Many of them
are threatened with shutdowns because cheap natural gas has made
their reactors uncompetitive.
"The agency’s proposal gave an odd mathematical formula for
evaluating nuclear plants’ contribution to carbon emissions. It said
that 5.8 percent of existing nuclear capacity was at risk of being
shut for financial reasons, and thus for states with nuclear
reactors, keeping them running would earn a credit of 5.8 percent
toward that state’s carbon reduction goal.
"Since receiving tens of thousands of comments on the proposal, the
agency is now reviewing the plan. It must evaluate all comments
before it sets a final rule, which it hopes to do by June. That
rule, however, is likely to be challenged in court.
"Under the proposed formula, if a state closed a 1,000-megawatt
nuclear plant and replaced 5.8 percent of it, or 58 megawatts, with
carbon-free electricity, it would be deemed to be 'carbon neutral.'
The state would reach the benchmark even if the other 942 megawatts
of power generated came from a carbon-emitting source like natural
gas combustion.
"Conversely, a state that kept all its nuclear plants open until
2030 could claim a credit for 5.8 percent toward its carbon
reduction goal.
"The 5.8 percent figure for nuclear power plants puzzled even
opponents of such power sources."
