*Many “Words of Wisdom” on Humanities Climate Future from Radio 
Ecoshock’s Alex Smith*
Paul Beckwith
Apr 27, 2023
About ten years ago Alex Smith called me for the first time to invite me 
on his radio program “EcoShock Radio” or “Radio EcoShock”; I always 
interchange the two words.

Since then, I’ve chatted with Alex on his program two or sometimes three 
times per year. I’ve always thought that his interviews are the best, 
since he knows so much about climate, the environment, science, and most 
other topics.

In a recent post, Alex stepped out of his normal routine of interviewing 
top scientists, authors, activists, etc. and told us what he thinks 
humanity and civilization has in store for it over the next few years, 
few decades, and longer.

I highly recommend you listen to what he has to say, and read what he 
has to say; I agree with most of his thoughts and think that they are 
very insightful. They are reasoned and nuanced, and emphasize that we 
just don’t know what how our future will play out since predicting 
future human behaviour and actions is a fools game.

Alex and I certainly agree that “doomers” who are certain humanity will 
go extinct in 3 years or so are off their rockers, and are 
self-delusional, even cult-like. We just don’t know, and anybody that 
seems certain of a specific extinction date a few years off, etc. is 
just nuts, and laughably so...

*Rapid Heating of Oceans Frightens Scientists: Threatens Marine Life, 
Coastal Areas*
JUAN COLE
04/26/2023

Ann Arbor (Informed Comment) – The oceans are hot. They are hot in a way 
that surprises and distresses climate scientists, Everyone knew they 
would heat up because of the climate emergency. But no one thought it 
would happen this fast and with this intensity. Moreover, some of the 
side effects we are seeing, like less oxygen in the oceans, are 
positively frightening.

That is the conclusion of a paper published last week by Karina von 
Schuckmann et al., “Heat stored in the Earth system 1960–2020: where 
does the energy go?” in Earth System Science Data.

Because we have been burning gasoline to run our cars and burning gas 
and coal to heat our homes and office buildings, we have been putting 
tens of billions of tons of carbon dioxide into the atmosphere for 
decades, and have been spewing extra CO2 in some quantity since the 
Industrial Revolution began around 1750. Carbon dioxide is a 
heat-trapping gas. Earth is heated by sun rays, but a lot of the heat 
they brought to the earth used to dissipate right back into outer space 
through our oxygen-nitrogen atmosphere that only had 280 parts per 
million of carbon dioxide. Now, we are averaging 417 ppm of CO2, and the 
planet has heated up significantly, by nearly 2 degrees F., in the past 
little over a century.

Where has all that extra heat gone? Well, 87% of it has gone into the 
oceans. They will also absorb the carbon dioxide itself, making them 
much more acidic. The authors point out that ocean heating is a good 
proxy for global heating and the effects of the climate emergency in 
general.

The authors observe, “The long atmospheric lifetime of carbon dioxide 
means that [extra heating and its effects] will remain positive for 
centuries, even with substantial reductions in greenhouse gas emissions, 
and lead to substantial sea-level rise, ocean warming, and ice shelf loss.”

Most of the heat that has gone into the ocean is stored in the 2100 feet 
closest to the surface, though the next level down is also heating up. 
In fact, recent research has shown that some heat waves reach all the 
way to the floor of the ocean.

Von Schuckmann and her colleagues looked at heat gain in the atmosphere 
above the oceans and found that it is accelerating, with recent decades 
heating up much more quickly than the average since 1971. In 2006-2023 
there was a big increase in the rate of heating.
The rate of sea level rise varies from place to place, but overall it 
has doubled since the 1990s. Back then, the seas were rising about 2.3 
millimeters a year, but in 2013-2023 it is 4.6 mm annually.

Just this month, April 2023, ocean surface temperatures spiked to a new 
high, leaving scientists scratching their heads. In the first week of 
April, the average was nearly 70 degrees F. (21.1 C.), which is the 
highest average temperature recorded since record-keeping began in the 
late 19th century.

Hot ocean surface water, and hot levels below that, are bad for many 
reasons. Hot water takes up more space than cold water, which 
contributes to sea level rise. The hot ocean surface waters provide the 
energy to drive hurricanes and cyclones, making them more intense. 
Warmer water has more water vapor in the air above it, so those massive 
storm systems cause heavier precipitation and flooding. The extra 
evaporation and water vapor also contributes to further global heating, 
since water vapor is a greenhouse gas that keeps heat from radiating 
into space. Hot ocean water also helps melt ice in places like Greenland 
and Antarctica. Land ice that melts runs into the oceans and that raises 
their level, threatening low-lying cities and plains. The hot ocean 
water develops oxygen deserts, causing dead zones. Some marine life 
can’t survive a sudden increase in temperature, and if this phenomenon 
continues we could see a mass die-off. Some 10% of humanity depends on 
fishing for its nutrition.
For these reasons, the new scientific findings are highly alarming.

/[ renewed sense of dread  ]/
*Why are ocean temperatures warmer than ever? Even experts are 
scratching their heads*
Fiona Harvey
As heatwaves, disasters and extreme weather afflicting people on land 
grab our attention, the role of the world’s oceans in the climate crisis 
is often overlooked. Perhaps we should be paying more heed: for the best 
part of two months now, something very strange has been happening in the 
oceans. Something very worrying.
- -
Meteorologists have been expecting an El Niño this year, and had already 
warned of its potential warming impact. But the current ocean 
temperature anomaly cannot be attributed to El Niño, as that weather 
system is still building up in the Pacific, and has not developed 
sufficiently yet to have an impact.

Prof Mike Meredith, of the British Antarctic Survey, told the Guardian 
it was “very concerning”, and while it was still too soon to tell what 
exactly was going on, if the phenomenon continued it “could be the start 
of something very serious”.

Covering two thirds of the planet, the oceans play a vast role in the 
climate system. They have absorbed about 90% of the extra energy we have 
put into the atmosphere from fossil fuel burning, and the amount of 
carbon dioxide they are absorbing is so great they are acidifying.
- -
“Hearing about these recent data has made me feel this deep sense of 
dread. It’s not like we didn’t know that the ocean was warming and that 
the death of some of the most precious ecosystems and species was 
likely, if not inevitable, within the next decade or so. But these 
extremes imply that things are changing faster than was predicted,” 
Perrin told me.

“It’s hard to reckon with what that means – not only for life in the 
ocean, but for life everywhere else too.”

/[ Movies and Climate - Yale sponsored -- a video discussion and overview ]/
*Climate Change and the Big Screen*
On March 29, 2023, the Yale Center for Environmental Communication and 
the 2023 Environmental Film Festival at Yale hosted a panel discussion 
on “Climate Change and the Big Screen,” exploring Hollywood’s role in 
climate change and culture change, and featuring a preview of a new 
exciting TV series. The scripted drama series “Extrapolations” by 
executive producer Scott Z. Burns (Contagion, An Inconvenient Truth) 
launched in March, 2023 on Apple TV+ and it depicts a possible future 
where unmitigated climate change increasingly impacts our everyday 
lives. Dr. Anthony Leiserowitz, Founder and Director of the Yale Program 
on Climate Change Communication, moderated a conversation with Dorothy 
Fortenberry, Executive Producer of Extrapolations, Anna Jane Joyner, 
Founder and CEO of Good Energy Story, and Emily Coren, Science 
communicator affiliate at Stanford University’s Dept. of Psychiatry & 
Behavioral Sciences.
--Climate storytelling is often centered around the worst case scenario, 
but EXTRAPOLATIONS paints an idea of what the near-future could look 
like in people’s daily lives with a 2.5-3 degree warming scenario 
starting in the year 2037, through 2070.
--The show portrays not only the physical health impacts of climate 
change, but also social and technological innovation.
--Talk is not a substitute for action, but is a necessary condition for 
action – films and entertainment education, in particular, are 
underutilized channels to advance the narrative of climate change 
communication and help audiences feel less alone.
--Perhaps more than a lack of climate storytelling, we’ve lived through 
a very successful climate communication campaign designed to convince 
the public that climate change is controversial, polarizing, and a 
question of belief.
-- The oil and gas industry has played a part in the film industry for 
many decades, driving a very specific narrative.
-- Massive global problems like the mass biodiversity extinction are 
tough to process; storytelling with parallel characters can help people 
mentally and emotionally comprehend and feel what is at stake.
-- Stories can provide a role model that people can identify with – 
people learn by watching the behavior of others (mirroring and 
modeling), which can collectively inspire a variety of actions to 
improve climate outcomes within their respective spheres of influence.
--No single story can speak to every audience – it will take many 
different forms of content, which come with different costs.
-- Film executives and decisionmakers grapple with a balance between 
wanting to avoid “pushing boundaries” and fear of being “left behind” 
amidst social change.

There are a host of solutions to help climate change action, but how do 
we tell what's worth the hype, and what's just greenwashing? From solar 
pv, to wind power, plus nuclear and even geoengineering. So are 
renewables worth it, and could the future of fusion save the day? I'm 
joined by @EngineeringwithRosie to break down the tools that could help 
save us from climate break down.

And don't forget to watch the video over on Rosie's channel all about
