Feb 3, 2024
Dr. Richard and Dr. Karen Alley take vital signs of Thwaites Glacier in 
Antarctica to see if it is deserving of the "Doomsday Glacier" 
nickname.  Three vital signs are examined throughout the series to 
access how this glacier may single handedly impact future predictions of 
sea level rise.  In this episode, the speed of the glacier over the last 
20 years is analyzed using satellite imagery. Episode One of a 
three-part series.  This video is part of the U.S. Ice Drilling 
Program's School of Ice Virtual Field Lab Series. (CC)

*Massive damage at Thwaites Glacier.*

Saturday, February 24, 2024
Anyone who blogs on Daily Kos is aware that the world's ice is melting, 
causing sea level rise, changes in the balance of fresh versus salt 
water in the oceans of the world, a loss of reflection of solar energy 
back into space that has significantly increased heat energy into the 
oceans, coastal erosion.

The loss of ice around Antarctica ice and sea ice reflectivity 
(2023-2024 is the fourth lowest on record) has changed ocean currents, 
damaging the ability to regulate carbon in the atmosphere. "This area is 
where the deep water of the oceans rises to the surface, where it 
mingles with the air, changes, and reforms, sinking back into the 
depths. This moment of air-sea exchange of CO2 greatly impacts the 
overall amount of CO2 the ocean keeps safely sequestered in its depths."
West Antarctica is most vulnerable to rapid and devastating ice loss. 
Thwaites has been in the news as the glacier holds up to 2 feet of sea 
level rise. Thwaites Eastern Ice Shelf is the plug that keeps inland ice 
from flowing into the sea. If we lose it, that will add another 8 feet 
of sea level rise, inundating Earth's coastal cities from Shanghai to 
Lagos to New York City and beyond.
*From first author Erin Petit of Oregon State University. (2021)*
The Thwaites Eastern Ice Shelf (TEIS) buttresses one third of Thwaites 
Glacier. Removal of TEIS has the potential to increase the contribution 
of Thwaites Glacier to sea level rise by up to 25\%. Recent research 
shows that the ice shelf is losing its grip on a submarine shoal that 
acts as a pinning point and the shear margin that separates TEIS from 
the Thwaites Glacier Tongue has extended, further weakening the TEIS 
connection to the pinning point. A sequence of Sentinel-1 radar imagery 
shows that parallel wing and comb cracks have recently formed rifts at 
high angles to the main shear margin and are propagating into the 
central part of the ice shelf at rates as high as 2km per year. We use 
satellite data, ground-penetrating radar, and GPS measurements to 
suggest that final collapse of Thwaites Glacier’s last remaining ice 
shelf may be initiated by intersection of rifts with hidden basal 
crevasse zones within as little as 5 years.

The central part of TEIS has no obvious surface crevasses and smooth 
surface topography, except for the surface expression of a pronounced 
basal channel aligned parallel to ice flow. Despite this smooth surface, 
ground-penetrating radar shows a weak zone of thin ice and complex basal 
topography, including numerous basal crevasses, that is not in local 
hydrostatic equilibrium. This local disequilibrium suggests the presence 
of elevated vertical shear stresses that further weaken this critical 
part of the ice shelf. GPS stake network observations show no measurable 
regional strain in the horizontal plane because large-scale flow is 
being accommodated by the lateral shear margin.

In the near future, the propagating rifts are likely to intersect this 
weak zone, triggering rifting along the basal crevasses and, 
subsequently, along the basal channel and a into secondary set of basal 
crevasses on the eastern side of the basal channel. This ``zigzag’’ rift 
sequence would disconnect the main flow from the influence of the 
pinning point (and compressive arches) and will ultimately lead to a 
complete disintegration of the ice shelf.

The Thwaites Eastern Ice Shelf is the floating terminus of the Thwaites 
Glacier, one of the fastest changing glaciers in Antarctica and 
contributing as much as 4\% of global sea level rise today. This 
floating ice shelf is stabilized offshore by a marine shoal and acts as 
a dam to slow the flow of ice off the continent into the ocean. If this 
floating ice shelf breaks apart, the Thwaites Glacier will accelerate 
and its contribution to sea level rise will increase by as much as 25\%. 
Over the last several years, satellite radar imagery shows many new 
fractures opening up. Similar to a growing crack in the windshield of a 
car, a slowly growing crack means the windshield is weak and a small 
bump to the car might cause the windshield to suddenly break apart into 
hundreds of panes of glass. We have mapped out weaker and stronger areas 
of the ice shelf and suggest a “zig-zag” pathway the fractures might 
take through the ice, ultimately leading to break up of the shelf in as 
little as 5 years, which result in more ice flowing off the continent.
The media will never tell you, but the eastern ice shelf is collapsing 
as I type...

*Your guide to 2024’s best environmental films*
Five highlights from the 2024 Wild and Scenic Film Festival — and how to 
host your own mini festival this weekend.
by DAISY SIMMONS
FEBRUARY 21, 2024In Nevada City, California, an environmental film 
festival kicked off to good news when the gold country community 
decisively rejected a proposed new gold mine. Between news that the 
board of supervisors had just unanimously denied the bid to reopen an 
old mine and the fact that 100+ inspiring films were set to screen 
around town this February weekend, the sense that community action can 
and does pay off was unusually clear at South Yuba River Citizens 
League’s 22nd Wild and Scenic Film Festival in Nevada City and Grass 
Valley, California.

After all, during the 2023 festival weekend, dozens of locals had taken 
to the main street with yellow signs and “hey hey, ho hos” rallying in 
opposition to the mine. What a difference a year (and the hard work of 
committed people) makes.

“Today we stopped the mine!” said South Yuba River Citizens League 
Executive Director Aaron Zettler-Mann to whoops and cheers at this 
year’s opening reception — held with standing-room-only in a historic 
stonewalled room that’s rumored to be haunted, as specialty and 
nonalcoholic brews alike flowed freely from festival sponsor Sierra 
Nevada. After other welcoming remarks by Shelly Covert, the spokesperson 
for the Nevada City Rancheria Nisenan Tribe; and comments on the state’s 
experiences of climate change from Wade Crowfoot, California’s Natural 
Resources Secretary; Nevada City Mayor Daniela Fernández rounded out the 
program by expressing a feeling shared by many in the room: “Hope 
sometimes feels more fleeting than ever, but here I’m reminded what 
resiliency and hope look like.”

 From that point on through the rest of the February weekend, an 
action-packed agenda kept attendees like me booking it between film 
screenings and related events — from fireside chats, coffee talks, 
hikes, and even a special rock-climbing session with filmmakers, to 
workshops on watershed restoration, sustainable investing, and youth 
activism. And in keeping with the festival motto “where activism is 
inspired,” volunteers collected more than 500 signatures for a petition 
to protect California salmon.

*Five highlights from this year’s Wild and Scenic Film Festival*
Ready to experience some of the inspiration for yourself? Read on for 
five big takeaways from this year’s selection, and learn how to screen 
some of them in the comfort of your own home by checking out the virtual 
festival, which continues through Feb. 25, 2024.

*1. “Hey hey, ho ho, [XYZ] has got to go!”* Festival HQ aka Nevada 
County was by no means the only community organizing against the odds to 
protect planet and people. The feature-length documentary “Patrol” 
(1:23) zooms in on an Indigenous community defending Nicaraguan 
rainforests from deforestation in the form of cattle farms. Reportedly 
illegal to screen in Nicaragua, the film highlights animal agriculture 
as one of the biggest drivers of biodiversity loss and a major driver of 
climate change — while painting a stirring portrait of a people fighting 
to defend their homelands. (Watch the trailer or unlock the film session 
here through Feb. 25, 2024.)

Shorter standouts of activism in other parts of the world include 
“Burning Injustice,” an 18-minute short featuring Latino farmworkers in 
central California rallying against one of the state’s last waste 
incinerators, and “Keepers of the Land,” a 28-minute look at the Kitasoo 
Xai’xais Nation’s quest to reclaim its rightful power over the land on 
Canada’s West Coast.

*2. Ripple effects are inevitable, even if at first they’re not clear.* 
More people are waking up to the truth that what happens in the Arctic 
does not stay in the Arctic — a tenet that rings true for many 
climate-related issues and actions.

In “Deep Rising,” (trailer/host a screening) a feature executive 
produced and narrated by Jason Momoa (aka Aquaman), we get a 
behind-the-scenes look at the often hidden but accelerating race to mine 
minerals from the ocean floor, against a backdrop of beautiful 
cinematography of rarely seen and unfathomably fragile creatures of the 
deep. While a massive seabed extraction outfit promotes its efforts as 
essential to the energy transition, the 1:33-hour feature-length film 
casts dark light on that platform saying there’s not been nearly enough 
time for real scientific assessment on the impacts of deep-sea mining, 
arguing that “critical minerals are not the solution; they are the new oil.”

Instead of extracting more and devastating deep-sea ecosystems — and in 
turn, the human communities who live in coastal areas — the film argues 
we should put more effort toward harnessing energy from what we do have 
readily available, everywhere: oxygen and hydrogen. Crossing oceans to 
bring viewers to Papua, New Guinea, “Deep Rising” reveals a community’s 
deeply personal response to a major seabed mining operation that has 
been in the works and stands to threaten their way of life. Fortunately 
for the Papuans, they have already learned from cautionary tales of 
other island communities not to be fooled by smooth-talking outsiders.

In its U.S. premiere, the Canadian-filmed “Nuked” (1:30) [trailer] is an 
Oppenheimer-esque exploration of the long-term impacts of nuclear 
testing on the people of the Marshall Islands during the Cold War — who 
were told would be taken care of for their troubles. Spoiler: They were 
not. Focusing on the human victims of the nuclear arms race, the film 
traces the displaced community’s ongoing struggles even as climate 
change poses a new existential threat, ultimately serving as a painful 
reminder that those most impacted by climate change are also often least 
responsible for it.

*3. We are all invited — or at least we should be.* A good number of 
films focused on themes of environmental justice and expanding access to 
environmental experiences. For example, in “Farming while Black,” (1:15) 
Afro-Indigenous farmers employ regenerative agricultural practices as a 
key solution to climate change. (Click here for an excerpt of the film 
discussing carbon reduction and the impacts of industrial agriculture.) 
An entire session was dedicated to The Sense of Belonging, with four 
films exploring different connections within nature, sport, and family 
history to reflect on tales of immigration and people’s sense of being 
part of a larger whole.

Inclusive sustainability also means helping expand access to nature for 
people from diverse backgrounds, as seen in films such as “Inward” (22 
min), where an artist explores what it means to be a Black man in 
nature, “Apayauq” (16 min), where the first out transgender woman sets 
out to complete Alaska’s Iditarod dog sled race, and “In the Dirt” (40 
min), where Navajo leaders work to expand access to biking in the Nation.

There are other talent- and interest-based ways we are all invited, too. 
Artists, for instance, can participate in climate change, as evidenced 
by, among others, “Bright Toh: Unsung Hero,” about a Cameroonian painter 
raising awareness for endangered species with art. Thrill-seekers can 
also join sustainability efforts while pursuing adventure sports. For 
example, in “The Engine Inside” (1:23), we meet six cycling activists 
from different parts of the world, all helping more people realize the 
climate, social, and physical benefits of biking. (This one you can 
catch streaming online anytime.)

*4. More people are recognizing the connections between mental health 
and the environment. *Time in nature can be a boon for mental health, 
according to several films including “Forward” (16 min), in which one 
plus-size woman of color rallies others to connect on the trail, 
“Daughter of the Sea” (18 min, S. Korea), where a woman finds healing 
from depression in the ocean, and “Light Beams for Helena” (8 min, 
Mexico), where a woman scuba dives to cope with depression.
*
5. A little inspiration can go a long way *… whether it’s a reminder of 
the sheer beauty of nature or a piece of great news. A clear audience 
favorite in the former category this year was “Out There: A National 
Parks Journey” (1.5 hours), which earned a standing ovation for the 
attending filmmaker. Spanning a 10,000-mile road trip through the 
national parks, the film shares real stories of people’s love for the 
parks. Gorgeous cinematography is at heart conservation-oriented, with 
the director’s stated intent to inspire future preservation efforts.

And yes, despite the often discouraging headlines in the world, good 
news really is out there, too. Take “Blue Whales: Return of the Giant” 
(45 min) for one, an inspirational story of a species rebounding from 
the edge of extinction. (Now playing at science museums across the country.)

In the category of “hard work can pay off” come several heartening 
films, each heralding good news in its own way, whether restoring sloth 
habitats in Costa Rica or stopping industrial-scale salmon farming in Maine.

How to host your own mini film festival — THIS WEEKEND ONLY
Grab the popcorn: Wild and Scenic is offering a series of virtual film 
sessions for $20 a pop to screen at home through this Sunday, Feb. 25, 
2024. The following are a few selections we recommend:

Art+Nature (11 films): Come for the “Toxic Art,” where an art professor 
sets out to convert coal mining pollutants into paint; stay for the 
“Losing Blue,” which grapples with the loss of the otherworldly blues of 
ancient mountain lakes, now fading due to climate change and “Inward,” 
described above.

Farming Stories (9 films): Regenerative agriculture dominates the lens 
in this session, which addresses everything from sustainable livestock 
farming in Colorado and coffee, birds, and biodiversity in Colombia to 
agave and bat populations in Mexico and ice harvesting in Maine.

Inspiring Journeys (2 films): Unlock this session to view “Out There” 
(featured above), and “Tracing History” about a Chinese American woman’s 
journey along American West railroads largely shaped by her ancestors.

Real Action (9 films): This session leads with “Won’t Give Up,” the 
Yo-Yo Ma musical collaboration previously featured on YCC, and also 
includes “Healy,” which traces an ice cap polar cruiser as it explores 
dwindling sea ice; “Burning Injustice” (detailed above); “Bright Toh” 
(see above); and dark comedy “Suzie and Jenny.”

Got kids? Cue up Wild Child. Got plans that keep you from virtual 
festing this weekend but still want to see the films? Check Wild and 
Scenic’s On Tour schedule to see if the tour is making its way to your 
area. Upcoming stops include Madison, Wisconsin; Annapolis, Maryland;

/[The news archive -  ]/
/*February 26, 2005 */
February 25, 2005: In a piece on state-level efforts to address carbon 
pollution, the Boston Phoenix's Deirdre Fulton notes:

    "Though the United States accounts for almost 25 percent — more than
    any other single country — of the world’s global-warming emissions,
    advocates say there’s been little federal action on this issue since
    at least 2001. That’s when George W. Bush, echoing concerns that had
    also been voiced by his predecessor Bill Clinton, opted out of
    Kyoto, citing national economic concerns and calling on developing
    nations to commit to greater sacrifices than they do under the
    current agreement. No wonder China, India, Mexico, and Brazil signed
    on, say US and Australian leaders. They have much less to lose as
    more stringent emissions regulations go into effect for other
    nations worldwide.

    "The US position may or may not be fair, but we do know this much:
    it doesn’t move us very far toward addressing the looming problem of
    global warming. And that makes regional and state-level efforts all
    the more important."
