[The massive ice shelf FOX calls the “Doomsday glacier” is floating on warm water]
warm water beneath its grounding zone (grounding line) is accelerating the
melting of a key Antarctic glacier (74,000 sq. mi). New research on the Thwaites
Glacier (lately dubbed the Doomsday Glacier by no less than FOX News) on the
West Antarctica Ice Sheet shows the water underneath the floating ice shelf to
be about closer to 36F. The glacier is
melting from below.
The Thwaites mass is an Ice Shelf, a hybrid formation that rests on bedrock on one end while floating on the other. The grounding line of these ice shelves – where the glacier meets land – anchors the ice, and also serves to hold back the much larger mass of land ice behind it. The existence of warm waters beneath the grounding line is more bad news for the stability of the Antarctic continent and the growing threat of rising sea levels.
measurements were taken by a team from the International Thwaites
Glacier Collaboration, which drilled a bore hole half a mile through
the ice at the grounding line and lowered instruments into the water. The news follows last year’s discovery of a
mammoth cavity beneath the glacier.
that such warm water was just now recorded by our team along a section of
Thwaites grounding zone, where we have known the glacier is melting, suggests
that it may be undergoing an unstoppable retreat that has huge implications for global sea level rise,” said David Holland, director of NYU’s Environmental
Fluid Dynamics Laboratory and NYU Abu Dhabi’s Center for Global Sea Level
Change in the official news release.
The Thwaites is
about the size of Florida. If all of its ice flows into the ocean, it will
raise sea levels an additional 2 feet on its own.
One year after extreme weather induced a mining waste dam collapse (271 dead) catastrophe, record rains have wrought flooding and landslides in the Brazilian state of Minas Gerais. Dozens are dead and missing and thousands have been evacuated as rains continue for the third day.
New records were set for most rainfall in a 24 hour period.
ADD DUST STORMS AND DEVASTATING HAIL TO AUSTRALIA’S APOCALYPTIC TROUBLES:
The wildfires that have consumed
Australia’s southeast, including areas around it’s major population centers,
have gotten plenty of media coverage. That is due in large part to the good
visuals that accompany this type of story. An area about the size of Virginian
has been burned. Millions of animals and birds have died. The economic toll had
not even begun to be calculated when the area was hit with a massive dust storm
followed by an apocalyptic hail storm.
2019 was the hottest, driest year on
record in Australia, which is saying something. Summer is only half over. With
no moisture in the air, the intensity of these fires is hard to describe.
INDONESIA RECORD STORMS / JAKARTA SINKS
Beginning New Year’s Day, Jakarta has
been inundated by catastrophic storms that brought intense rainfall and lethal
flooding to the city of 30 million, with 15 or 20 inches coming in 24 hours. Even
in a megalopolis prone to flooding, this storm is in a class of its own.
Millions have been evacuated. The situation of course, is exacerbated by stupid human tricks, because massive
quantities of groundwater have been sucked out from beneath the city. As is
often the case, there is both too much water and not enough to drink.
Monsoons are normal in this region, but the new weather patterns bring much greater quantities of rain over the course of fewer, less predictable storms.

several records last summer as well.
Record highs were also reported in
Boston and New York, running 35 degrees higher than normal.

Coastal towns were lashed by 60-foot waves, and villages

OCEAN TEMPERATURES HOTTEST EVER IN 2019 AND CLIMBING FASTER
The heat in the world’s oceans reached a new record
level in 2019. Although 2019 was only the “second warmest” on record for
atmospheric temperatures, the oceans are heating up faster than ever. Oceans
absorb and store 90% of solar heat energy. Hotter seas cause more severe storms and further contribute to rising seas through
thermal expansion and kill marine life.
For the most part, people who accept climate change (and even those who understand that it is caused by humans remain unaware of the fact that this is a climate emergency that has been under-stated rather than over-stated. Seen globally however, the realities may be more persuasive. This is a small sampling of global events and conditions from the past year.
ARCTIC AMPLIFICATION: The Arctic region is warming twice as fast as the rest of the planet. The global consequences in terms of disruption to wind and weather patterns are hard to overstate.
ALBEDO FEEDBACK CYCLE: Self-perpetuating feedback cycle, as sea ice melts, more solar radiation heats the open water, ice melts faster.
PERMAFROST FEEDBACK CYCLE: Permafrost is thawing, releasing CH4 and CO2 into the atmosphere, causing more warming, causing more permafrost melt. The quantity of CH4 trapped in permafrost is unknown.
SLOWING AMOC (Atlantic Meridional Overturning Circulation): A significant tipping point, the global ocean circulation that drives the Gulf Stream has been slowing. The ocean current is a critical factor in regulating temperatures.
MASSIVE MARINE HEAT WAVE: The “Blob “ is back. This Pacific heat wave is the second worse ever. The worst was the Blob of 2014 – 2016, which lasted three years, causing serious disruption to marine ecosystems and marine life on the west coast, not to mention the largest toxic algae bloom in the history of the US West Coast. Marine heat waves are increasing in frequency, compromising underwater ecosystems which as kelp forests and coral reefs.

A new report from
National Oceanic and Atmospheric Administration summarizes the economic consequences.
COASTAL INUNDATION: Major urban
centers face rapid ocean rise, including Charlotte, NC, Miami, Norfolk, VA,
Shanghai, China, Bangladesh, Alaska, Mumbai, Solomon and other Pacific Islands.
GLOBAL WILDFIRES/DEFORESTATION: Supercharged Wildfires burn hotter and are harder to control. Amazon gets the coverage, but out of control wildfires burned in 2019 in Australia, Bolivia, Chile Indonesia, Cyprus, Siberia, Alaska, Southern Europe and California. Firenados are increasingly common. Global outbreaks of wildfires is stressing resources. Megatons of carbon are released into the atmosphere. The Wildfire/Deforestation Feedback Cycle pours more carbon into the atmosphere and accelerates global warming.

UNPRECEDENTED HURRICANE /CYCLONE BEHAVIOR: Hurricanes and storms of all types are more intense, move more slowly, contain more moisture (causing more damage), and intensify more rapidly. Damage over the past few years is unprecedented. For three hurricane seasons in a row, storms with record-breaking rainfall have caused catastrophic flooding in the southern United States:

SHARP INCREASE IN METHANE RELEASES. Atmospheric CH4 is highest in 800,000 years, generating more greenhouse gases via Permafrost Thaw Feedback Cycle #2.

Global methane concentrations increased 250 % since pre-industrial time.
