*Drought sparks drinking water concerns as saltwater creeps up 
Mississippi River*
Louisiana residents who rely on river for drinking water warned of 
potential health risks in next few weeks

Fri 22 Sep 2023
The New Orleans mayor, LaToya Cantrell, signed an emergency declaration 
for the city on Friday amid concerns about saltwater from the the Gulf 
of Mexico that has been creeping up the drought-hit Mississippi River in 
Louisiana.

The declaration came amid concerns the saltwater, which is impacting the 
river because it is at such low levels, could impact the drinking water 
of thousands of residents in the next few weeks...
- -
The saltwater has already entered the drinking water of communities 
south of New Orleans – from Empire Bridge to Venice, Louisiana – making 
the water undrinkable for about 2,000 residents and causing water 
outages at local schools. As the saltwater moves upriver, it could 
affect the drinking water for another 20,000 people in Belle Chasse. 
After that it could reach the drinking water intake for the New Orleans 
community of Algiers, across the river from the French Quarter...
- -
“This will be a difficult nut to crack,” she said.

Sea level rise will make the conditions that allow saltwater intrusion 
into the Mississippi River more likely in the future, said Soni 
Pradhanang, an associate professor of hydrology and water quality at the 
University of Rhode Island. Climate change is also expected to 
exacerbate droughts by making them longer and more frequent. “We’re only 
going to see this happening more,” she said. “Sea level rise will lead 
to increased salinity as more of this seawater pushes up into the 
estuaries and inland.”

*‘Climate villain’: scientists say Rupert Murdoch wielded his media 
empire to sow confusion and doubt*
The tycoon, who is stepping down from News Corp and Fox, has used his 
outlets to promote denial and delay action, experts say

Fri 22 Sep 2023

Scientists have described the media tycoon Rupert Murdoch as a “climate 
villain” who has used his television and newspaper empire to promote 
climate science denial and delay action.

Murdoch’s outlets, including Fox News, the Wall Street Journal and The 
Australian, have long been known to promote doubts about the cause and 
consequences of the climate crisis. Scientists said this had caused 
lasting damage.

Following the news Murdoch is stepping down as chairman of News Corp and 
Fox Corp, Dr Joëlle Gergis, a climate scientist at Australian National 
University, said: “It’s hard to think of another person who has 
single-handedly done more to muddy the public’s understanding of climate 
change.

“We have wasted decades debating the fundamental science in the media, 
when we really should have been focused on urgently implementing climate 
policies that will genuinely reduce emissions.

“Murdoch will be looked back on by historians as someone who used their 
media monopoly to influence the destabilisation of the Earth’s climate.”

Prof Lesley Hughes, a member of the Australian government’s independent 
advisory group the Climate Change Authority and of the not-for-profit 
Climate Council, said: “Rupert Murdoch has been extraordinarily damaging.

“He bears enormous responsibility for the world’s lack of necessary 
action on climate change. His outlets have actively promoted scepticism 
about climate science that has undermined the need to act.”

Prof Michael Mann, a climate scientist at the University of 
Pennsylvania, said Murdoch had been “one of the most destructive forces 
in modern history when it comes to climate action”.

“He has wielded his global media empire as a cudgel to sow confusion and 
doubt about the science and the solutions. He will go down in history as 
one of the greatest climate villains,” said Mann.

Dr Friederike Otto, senior lecturer in climate science at the Grantham 
Institute, Imperial College London, said: “There’s no doubt that the 
Murdoch empire has played an important role in letting the public 
believe that there was any scientific doubt that the burning of fossil 
fuel causes the climate to warm and that it is detrimental for society 
and ecosystems. It is a terrible legacy he leaves, that many people paid 
for, and are paying for, with their lives and livelihoods.

“Climate protesters are widely portrayed as people trying to make life 
difficult for the average person, whereas of course in reality they try 
to make it better. I’m very doubtful this fight will be any easier with 
just Rupert Murdoch stepping down and nothing else changing. The damage 
his empire has done is incredibly large.”

Murdoch described himself in 2015 as a “sceptic not a denier” of climate 
change. During a News Corp annual meeting in 2019 he said there were “no 
climate change deniers” around his company.

Independent bodies have challenged this. UK thinktank the Institute for 
Strategic Dialogue described Murdoch’s Sky News Australia as a global 
hub for spreading climate change misinformation.

In a foreword to a 2022 company environment report, Murdoch wrote News 
Corp was “filled with people who are creative and collaborative, and 
possessing an abiding sense of curiosity about the world around us”. He 
said the company took its environment goals seriously, but did not 
mention climate change. News Corp has a corporate target to reach net 
zero greenhouse gas emissions by 2050.

Fox Corporation announced on Friday that the former Australian prime 
minister Tony Abbott, who has repeatedly said he does not accept 
mainstream climate science and whose government repealed carbon price 
legislation, had been nominated for a board position. Rupert Murdoch’s 
son Lachlan, who is set to become the sole chair of Fox and News Corp 
after his father’s retirement, said Abbott had “skills, experience and 
perspectives” that would benefit the company.

Dr John Cook, who researches climate science misinformation at the 
University of Melbourne, said under Rupert Murdoch’s leadership News 
Corp had been “a major source of climate misinformation”.

“The damage they’ve caused is real and has been quantified by scientists 
– watching Fox News reduces people’s acceptance of the reality of 
climate change compared to watching other outlets.”

“Ironically, News Corp internally sought to take a leadership role on 
climate change by reducing their carbon footprint, while their media 
outlets have denied climate change and attacked the science. The 
hypocrisy is reminiscent of fossil fuel companies who internally 
recognised the reality of climate change while publicly casting doubt on 
the science.”

Dr Peter Gleick, a co-founder of the California-based Pacific Institute, 
said Murdoch was responsible for pushing “decades of dangerous climate 
misinformation and denial to millions of people”.

“His distortions have influenced policymakers and the public and wasted 
critical time that should have been spent slowing the climate crises we 
now see all around us.

“His influential outlets, from Fox to the Wall Street Journal, have been 
spewing and continue to sow deep climate disinformation, and they 
continue to support and promote biased, misleading opinion pieces and 
commentary from climate deniers and delayers.

“When our history is written, and the final roster of climate villains 
is posted, Murdoch will be at the top.”

Dr Andrew King, a climate scientist at the University of Melbourne, 
said: “The world would be in a much better place if [Murdoch] had used 
[his media empire] to accurately convey the science on climate change.

“Instead, he has helped foster climate denialism in Australia, the UK 
and the US, allowing governments to slow climate action.”

The Guardian contacted News Corp for comment.

*A climate scientist on how to recognize the new climate change denial*
Delay, deflect, downplay, and other ways fossil fuel companies block 
climate action.
By Avishay Artsy
Sep 22, 2023
For the past dozen years or so, every time the United Nations General 
Assembly holds its annual session in New York City, climate activists 
hit Manhattan to protest outside. They call it Climate Week. And this 
week has been a big one, with tens of thousands of protesters 
demonstrating as part of the New York March to End Fossil Fuels.

After a summer of extreme weather, Vox’s daily news podcast Today, 
Explained is tackling Climate Week with some help from a scientist — one 
who’s been at the center of climate science since before it was cool, 
and has some ideas on how we can keep the planet from getting too hot.

Michael Mann is a professor at the University of Pennsylvania and author 
of the new book Our Fragile Moment: How Lessons from Earth’s Past Can 
Help Us Survive the Climate Crisis. Mann is perhaps best known for the 
“hockey stick curve” in a 1998 paper he co-published about the planet’s 
rapidly rising temperature after a mostly steady millennium.

Mann spoke with Today, Explained host Sean Rameswaram about his 
experience fighting climate denialism, and the new tactics that have 
emerged from the fossil fuel industry and the groups it supports. Read 
on for an excerpt of the conversation, edited and condensed for length 
and clarity, and listen to the full conversation wherever you find 
podcasts...

*I want to ask you about another D-word that I think is related to the 
lack of policies that are going to make enough of a difference to save 
this planet. And that, of course, is doom. Climate doomerism.*

Yeah. And doomism has actually been weaponized by bad actors to convince 
even environmentalists that, “Hey, it’s too late to do anything anyway, 
so you might as well just give up trying to solve the climate crisis.” 
People who are ostensible climate advocates and environmentalists insist 
that it’s too late, and we just have to accept our fate. There are 
events, like mass extinction events in the past, that some of these 
doomists will point to and say, “Look what happened to the dinosaurs, 
what happened during the so-called Great Dying 250 million years ago 
when 90 percent of all species died out because of a massive release of 
carbon into the atmosphere through an episode of massive volcanism, 
that’s happening today.” There are prominent actors in the climate space 
who are literally making this claim. And they’re doing so by 
misrepresenting what the record of Earth history actually tells us about 
those events. We are at a fragile moment. We’re not yet past the point 
of no return. But if we don’t take substantial action and do so 
immediately, then we are due for some of those potential worst-case 
scenarios. So it is still up to us...
- -
*Is there a D-word out there that we haven’t talked about — not 
denialism, divisionism, delayism, doomism, deflection — that people can 
attach themselves to in a moment where critical decisions that are made 
could really shift the outcome?*

Yes ... We have to be determined now to take the actions that are 
necessary while we still can. Let’s be clear. We should all do 
everything we can within the constraints of our own lifestyles to 
minimize our environmental impact and to minimize our carbon footprint. 
But the most important thing an individual can do is to use their voice 
and their vote, because the policies that we need in place to 
decarbonize our economy, to lower carbon emissions by 50 percent over 
the next decade, the only way we can accomplish that is with policy. And 
so we need to vote for politicians who will do what’s right by us and 
act on climate, rather than the politicians who too often are simply 
acting as rubber stamps for polluters..

*Bursting air bubbles may play key role in glacier ice melts*
Steve Lundeberg

Updated Sep 18, 2023

Oregon State University research has uncovered a possible clue as to why 
glaciers that terminate at the sea are retreating at unprecedented 
rates: the bursting of tiny, pressurized bubbles in underwater ice.

The study shows that glacier ice, characterized by pockets of 
pressurized air, melts much more quickly than the bubble-free sea ice or 
manufactured ice typically used to research melt rates at the ocean-ice 
interface of tidewater glaciers.

Tidewater glaciers are rapidly retreating, the authors say, resulting in 
ice mass loss in Greenland, the Antarctic Peninsula and other 
glacierized regions around the globe.

“We have known for a while that glacier ice is full of bubbles,” said 
Meagan Wengrove, assistant professor of coastal engineering in the OSU 
College of Engineering and the leader of the study. “It was only when we 
started talking about the physics of the process that we realized those 
bubbles may be doing a lot more than just making noise underwater as the 
ice melts.”

Glacier ice results from the compaction of snow. Air pockets between 
snowflakes are trapped in pores between ice crystals as the ice makes 
its way from the upper layer of a glacier to deep inside it. There are 
about 200 bubbles per cubic centimeter, meaning glacier ice is about 10% 
air.

“These are the same bubbles that preserve ancient air studied in ice 
cores,” said co-author Erin Pettit, glaciologist and professor in the 
OSU College of Earth, Ocean, and Atmospheric Sciences. “The tiny bubbles 
can have very high pressures – sometimes up to 20 atmospheres, or 20 
times normal atmospheric pressure at sea level.”

When the bubbly ice reaches the interface with the ocean, the bubbles 
burst and create audible pops, she added.

“The existence of pressurized bubbles in glacier ice has been known for 
a long time but no studies had looked at their effect on melting where a 
glacier meets the ocean, even though bubbles are known to affect fluid 
mixing in multiple processes ranging from industrial to medical,” 
Wengrove said.

Lab-scale experiments performed in this study suggest bubbles may 
explain part of the difference between observed and predicted melt rates 
of tidewater glaciers, she said.

“The explosive bursts of those bubbles, and their buoyancy, energize the 
ocean boundary layer during melting,” Wengrove said.

That carries huge implications for the way ice melt is folded into 
climate models, especially those that deal with the upper 40 to 60 
meters of the ocean – the researchers learned glacier ice melts more 
than twice as fast as ice with no bubbles.

“While we can measure the amount of overall ice loss from Greenland over 
the last decade and we can see the retreat of each glacier in satellite 
images, we rely on models to predict ice melt rates,” Pettit said. “The 
models currently used to predict ice melt at the ice-ocean interface of 
tidewater glaciers do not account for bubbles in glacier ice.”

Right now, data from NASA attributes about 60% of sea level rise to 
meltwater from glaciers and ice sheets, the authors note. More accurate 
characterization of how ice melts will lead to better predictions of how 
quickly glaciers retreat, which is important because “it’s a lot more 
difficult for a community to plan for a 10-foot increase in water level 
than it is for a 1-foot increase,” Wengrove said.

“Those little bubbles may play an outsized role in understanding 
critical future climate scenarios,” she added.

The Keck Foundation, the National Science Foundation and the National 
Geographic Society funded the research, which also included Jonathan 
Nash and Eric Skyllingstad of the OSU College of Earth, Ocean, and 
Atmospheric Sciences and Rebecca Jackson of Rutgers University.

The study ha been published in Nature Geoscience.
