<b>Climate change could trigger gigantic deadly tsunamis from
Antarctica, new study warns</b><br>
By Ben Turner published about 10 hours ago<br>
Slippages in sediment beneath the Antarctic seabed could spawn
gigantic tsunamis as oceans warm.<br>
Climate change could unleash gigantic tsunamis in the Southern Ocean
by triggering underwater landslides in Antarctica, a new study
warns. <br>
<br>
By drilling into sediment cores hundreds of feet beneath the
seafloor in Antarctica, scientists discovered that during previous
periods of global warming — 3 million and 15 million years ago —
loose sediment layers formed and slipped to send massive tsunami
waves racing to the shores of South America, New Zealand and
Southeast Asia. <br>
<br>
And as climate change heats the oceans, the researchers think
there's a possibility these tsunamis could be unleashed once more.
Their findings were published May 18 in the journal Nature
Communications...<br>

<b>Abstract</b><br>
<blockquote>Antarctica’s continental margins pose an unknown
submarine landslide-generated tsunami risk to Southern Hemisphere
populations and infrastructure. Understanding the factors driving
slope failure is essential to assessing future geohazards. Here,
we present a multidisciplinary study of a major submarine
landslide complex along the eastern Ross Sea continental slope
(Antarctica) that identifies preconditioning factors and failure
mechanisms. Weak layers, identified beneath three submarine
landslides, consist of distinct packages of interbedded Miocene-
to Pliocene-age diatom oozes and glaciomarine diamicts. The
observed lithological differences, which arise from glacial to
interglacial variations in biological productivity, ice proximity,
and ocean circulation, caused changes in sediment deposition that
inherently preconditioned slope failure. These recurrent Antarctic
submarine landslides were likely triggered by seismicity
associated with glacioisostatic readjustment, leading to failure
within the preconditioned weak layers. Ongoing climate warming and
ice retreat may increase regional glacioisostatic seismicity,
triggering Antarctic submarine landslides.<br>

<b>DeSantis accused of ‘catastrophic’ climate approach after
campaign launch</b><br>
Republican ‘trying to out-Trump Trump’ on climate, expert says, as
governor says he rejects the ‘politicization of the weather’<br>
Oliver Milman @olliemilman<br>
Sun 28 May 2023<br>
Ron DeSantis has been accused of a “catastrophic” approach to the
climate crisis after he launched his campaign for US president by
saying he rejects the “politicization of the weather” and
questioning whether hurricanes hitting his home state of Florida
have been worsened by climate change.<br>
<br>
DeSantis, ... has previously dismissed concerns about global heating
as “leftwing stuff” and he expanded upon this theme during a Fox
News interview following his campaign launch...<br>
- -<br>
Michael Mann, a climate scientist at the University of Pennsylvania,
said that DeSantis’s stance towards climate science is “classic
projection”.<br>
<br>
“It is Ron DeSantis who is engaged in the ‘politicization of the
weather’ by denying basic, established science – the intensification
of tropical storms with human-caused warming of the oceans.”...<br>
- -<br>
...Bob Inglis, a former Republican congressman who now advocates for
a conservative response to the climate crisis....<br>
<br>
“He’s done some things in Florida designed to address the problem of
climate change, he could’ve been the post-Trump successful governor,
the solver of problems,” said Inglis.<br>
<br>
“But instead he’s choosing to be more of the anti-woke warrior than
Trump. He’s slugging it out in the Trump lane which is really a
terrible mistake. I’m hearing from Republicans in Florida ‘why is he
choosing this path?’<br>
<br>
“He could’ve said, ‘Hey, we are dealing with this climate issue in
Florida, let’s lead the world on this.’ Instead he’s trying to
out-Trump Trump.”<br>
<br>
Inglis said that while some senior Republicans fret they will lose
out on a younger generation of climate-concerned voters, they still
risk being beaten in primary races by candidates that back Trump’s
ongoing embrace of climate denialism.<br>
<br>
“People like (House of Representatives speaker) Kevin McCarthy know
that young conservatives want action on climate change and even if
Trump wins he will be a lame duck by 2026 and the party could start
moving on by then,” said Inglis.<br>
<br>
“The trouble is, the scientists say we don’t have the time to wait
for that. That really is the problem.”<br>

A growing number of people believe that humanity is doomed because

We're destroying our environment at an alarming rate. But it doesn't
need to be this way. Our new channel Planet A explores the shift
towards an eco-friendly world — and challenges our ideas about what
dealing with climate change means. We look at the big and the small:
What we can do and how the system needs to change. Every Friday
we'll take a truly global look at how to get us out of this mess.<br>

Hansen’s Brilliant New Paper: “Global Warming in the Pipeline”</b><br>
Paul Beckwith<br>
</font><font face="Calibri">May 25, 2023<br>
As can be seen on the splash screen image for this video, global
average temperature has trended upward at a very fast rate of 0.18
C per decade. Unfortunately for humanity, this trend has greatly
increased since 2010 to 0.27 C per decade. <br>
<br>
The root cause is the accelerating increase in concentrations of
atmospheric GHG from fossil fuel emissions, and the reduction of
aerosols contains sulphur by China and the global shipping
industry in the last decade or two (and in North America and
Europe before then). <br>
<br>
A key metric for climate is the Earth Energy Imbalance (EEI). It
is basically energy into the Earth system minus energy out. When
it is above zero, our planet warms. In 2010, the 6 year average
was about 0.6 W per m**2, and now it is 1.22 W per m**2. It is
accelerating upward even faster than Elon Musk’s rockets. <br>
<br>
Equilibrium Climate Sensitivity (ECS) is the warming that is
expected to occur with a doubling of CO2, considering fast (and
ultrafast) feedbacks only. Hansen’s new number is 4 C, as opposed
to the mainstream popular number of 3 C. <br>
<br>
Even worse, Hansen’s new paper shows that with present levels of
GHGs, in equilibrium our temperature would warm a whopping 10 C
(reduced to about 8 C if aerosols stayed at today’s levels). Not
only that, but global sea levels would rise 60 meters from
complete loss of ice on Greenland and Antarctica.<br>
<br>
This video is really a primer (basic introduction) on Hansen’s new
paper, updated just a week ago (May 19th, 2023). In subsequent
videos, I will be going over the nitty gritty details of this
landmark, 62 page scientific paper.<br>

May 29, 2014:<br>
The New York Times reports:<br>
</font>
<blockquote><font face="Calibri">"President Obama will use his
executive authority to cut carbon emissions from the nation’s
coal-fired power plants by up to 20 percent, according to people
familiar with his plans, and will force industry to pay for the
pollution it creates through cap-and-trade programs across the
country.</font><br>
<br>
<font face="Calibri">"Mr. Obama will unveil his plans in a new
regulation, written by the Environmental Protection Agency, at
the White House on Monday. It would be the strongest action ever
taken by an American president to tackle climate change and
could become one of the defining elements of Mr. Obama’s legacy.</font><br>
<br>
<font face="Calibri">"Cutting carbon emissions by 20 percent — a
substantial amount — would be the most important step in the
administration’s pledged goal to reduce pollution over the next
six years and could eventually shut down hundreds of coal-fired
power plants across the country. The regulation would have far
more impact on the environment than the Keystone pipeline, which
many administration officials consider a political sideshow, and
is certain to be met with opposition from Republicans who say
that Mr. Obama will be using his executive authority as a back
door to force through an inflammatory cap-and-trade policy he
could not get through Congress.</font><br>
<br>
<font face="Calibri">"People familiar with the rule say that it
will set a national limit on carbon pollution from coal plants,
but that it will allow each state to come up with its own plan
to cut emissions based on a menu of options that include adding
wind and solar power, energy-efficiency technology and creating
or joining state cap-and-trade programs. Cap-and-trade programs
are effectively carbon taxes that place a limit on carbon
pollution and create markets for buying and selling
government-issued pollution permits.</font><br>
<br>
<font face="Calibri">"Coal plants are the nation’s largest source
of the greenhouse gases that scientists say are the chief cause
of global warming."</font><br>
