Q & A
What is the main topic discussed in the script?
-The main topic discussed in the script is climate change, its implications, and the potential catastrophic events it could trigger.
How does the script describe the Earth's response to increased carbon dioxide levels?
-The script describes the Earth as a self-regulating machine that becomes disrupted when the composition of its atmosphere is altered by increased carbon dioxide levels, leading to a cascade of ecological and climatic changes.
What are the five scariest things mentioned in the script that could happen due to climate change?
-The script mentions: 1) Global warming and its impact on weather patterns, 2) Redistribution of growing conditions and fresh water, 3) Famine and war due to poor growing conditions, 4) Displacement and mass extinctions due to sea level rise, and 5) Ocean acidification leading to another mass extinction event.
What is the significance of the 'thermohaline circulation' mentioned in the script?
-The thermohaline circulation, also known as the global conveyor belt, is significant because it drives the distribution of heat and nutrients in the world's oceans, affecting weather patterns, supporting diverse marine life, and is sensitive to changes in carbon dioxide levels.
Why does the script mention the importance of the Amazon rainforest in the context of climate change?
-The script mentions the Amazon rainforest as a natural carbon sink that is being destroyed, which contributes to increased greenhouse gas emissions and exacerbates climate change.
What is the relationship between climate change and the melting of polar ice caps as discussed in the script?
-The script explains that as the Earth's temperature rises due to climate change, the polar ice caps melt, contributing to sea level rise and the potential for widespread displacement and ecosystem destruction.
How does the script suggest that small changes in average temperature can have significant impacts?
-The script suggests that even a small increase in average temperature can disrupt the Earth's self-regulating systems, affecting weather, agriculture, and wildlife, leading to more extreme weather events and ecological imbalances.
What is the potential impact of ocean acidification on marine life according to the script?
-The script states that ocean acidification, caused by increased carbon dioxide levels, can lead to mass extinctions by altering the pH levels that many marine species, particularly those at the base of the food chain, depend on for survival.
Why does the script mention the potential for hydrogen sulfide production in the event of a thermohaline circulation shutdown?
-The script mentions hydrogen sulfide production as a consequence of a thermohaline circulation shutdown because the lack of oxygen in the ocean depths would lead to an increase in anaerobic bacteria, which produce this toxic compound, potentially leading to widespread marine and coastal life death.
What is the script's stance on the urgency of addressing climate change?
-The script emphasizes the urgency of addressing climate change by outlining the severe and potentially catastrophic consequences of inaction, yet it also humorously acknowledges the presenter's own continued contribution to the problem through everyday actions like eating meat and driving.
Outlines
🌍 Climate Change: The Elephant in the Room
The speaker humorously addresses the ubiquity of climate change discussions and the skepticism surrounding it. They acknowledge the overwhelming evidence of global warming and the reluctance of some to accept human activities as the cause. The paragraph emphasizes the impact of human actions, such as burning fossil fuels and deforestation, on increasing carbon dioxide levels, which historically have led to disastrous climate events. The speaker outlines the five scariest potential outcomes of climate change, setting the stage for a detailed exploration in the following paragraphs.
🌡️ Global Warming and Its Ripple Effects
This paragraph delves into the consequences of the Earth's average temperature rise, highlighting how it disrupts natural cycles and ecosystems. The speaker explains that a slight increase in temperature can have profound effects on weather patterns, leading to extreme events like floods and droughts. The changes affect agriculture, with shifting growing conditions and water availability, potentially leading to food scarcity. The speaker also touches on the redistribution of populations and the potential for conflict over resources, emphasizing the interconnectedness of climate, agriculture, and human society.
🌊 Sea Level Rise and Ocean Acidification
The speaker discusses the threats posed by melting polar ice caps, which contribute to rising sea levels and the potential submersion of coastal cities and island nations. They also address the issue of ocean acidification, a result of increased carbon dioxide absorption, which threatens marine life, particularly those at the base of the food chain. The paragraph outlines the potential for mass extinctions due to these changes and the broader implications for biodiversity and the health of the planet's ecosystems.
🌀 The Threat of Thermohaline Circulation Shutdown
In this paragraph, the speaker explains the critical role of the thermohaline circulation, or global conveyor belt, in regulating the Earth's climate and supporting life. They discuss the potential for this system to shut down due to high carbon dioxide levels, which could lead to drastic climate changes, oxygen depletion in the oceans, and the proliferation of toxic hydrogen sulfide. The speaker paints a grim picture of a planet with altered weather patterns, inhospitable oceans, and a pervasive rotten egg smell due to the release of hydrogen sulfide, emphasizing the urgency of addressing climate change.
🤷♂️ Climate Change Inaction: A Puzzle
The final paragraph reflects on the speaker's personal struggle with climate change inaction despite understanding its severity. They express a common human tendency to continue with behaviors that contribute to the problem, such as consuming meat and using fossil fuels, even when aware of the consequences. The speaker calls for social scientists to investigate this paradox and find solutions to motivate behavioral change, ending on a note that underscores the complexity of human psychology in the face of environmental crises.

Transcripts
all right today I'm going to give it to
you straight about climate
[Music]
change perhaps you've heard of it like
on TV or something at this point I think
we're all pretty much at saturation on
climate change for the past 10 years
it's been all day and all night on the
news climate changes global warming
Trend climate change global warming
climatic changes climate change climate
change is real climate change is coming
to blow up your house and eat your dog
so basically I'm not going to be needing
that anymore and I'm not going to be
needing that but what does it even mean
and what does what it means mean and
should you even care uh yeah you should
care I realize that climate change is
one of those things that some people
don't believe in specifically there are
people who challenge the widely held
belief that it's getting hot in here
which I think was firmly established by
nelli in 2002 just before he requested
that we take off all our clothes and
that unfortunately turns out to not be a
particularly effective strategy to
combat global warming fun though
actually some of the deniers agree that
it's getting warmer they just disagree
that the cause is the way that we as
humans live our lives which is
understandable I guess because who wants
to believe that their actions are
hurting other people in the world and
other Generations as well you know
besides rational responsible adult
people people who want to do the right
thing if at all possible and what are we
doing that's so wrong well in the
immortal words of one of my heroes Nancy
Sinatra we've been messing where we
shouldn't have been a messing so we
release ah massive amounts of carbon
dioxide into the atmosphere by burning
coal and gas and oil and jet fuel and we
also really like to destroy natural
carbon sinks like the Amazon rainforest
and then in the place of those
rainforests we like to put other things
that produce greenhouse gases like
cattle and here's the kicker the Earth
has seen these massive increases in
carbon dioxide concentrations in our
atmosphere in the past and every time
it's been a complete disaster what
scientists can't completely agree on is
what nightmare apocalypse scenario is
going to get to us first or you know I
guess they could all all of them happen
all at once there's always that one
thing they are agreeing on not zombies
so we're safe from that so here are the
five scariest things that could happen
or probably are already happening
because of climate change so the number
five scariest thing about climate change
everything is just getting so confused
up in here so people talk about global
warming they're basically talking about
the fact that over the last hundred
years or so the average tempature of the
Earth has increased by about a degree
and a half Fahrenheit and most of that
increase has happened in the last 30
years or so so here's how you should be
thinking of the earth it's it's a
beautiful precisely calibrated and
self-regulating machine and it's more
complex and amazing than than we will
ever be able to understand seriously
guys it's a freaking Masterpiece but
let's say that a terribly intelligent
group of animals on its surface starts
to drastically alter the composition of
its atmosphere in that case all of those
elegant and beautiful self-regulating
systems start to go all screwy stuff
that seems totally inconsequential like
rain falling a few weeks later than it
otherwise would can affect when the
streams are full which changes when the
plants bloom which changes when the
insects hatch and that could affect
historically synchronized pollenization
of crops and fish spawns and bird
migrations and water supplies for
drinking irrigation what we're seeing
now with just over a degree difference
in the temperature of the earth is
significantly affecting our weather
already some places are flooding some
places are experiencing record droughts
we're seeing ice caps melting in the
historic ranges of animals and plants
either shrinking or expanding I mean
check it out in the past 10 years
they've actually had to change the
little maps on the back of seed packets
to tell you when to plant your cucumbers
the worldwide redistribution of growing
conditions and fresh water cuz you know
you have air conditioning and so it's
not too big of a deal if the world gets
super hot but you know who doesn't have
air conditioning cucumbers and cows and
other stuff that we like to eat those
things have to be outside that's how
they work and so they care if suddenly
everything gets super hot and dry and
right now a lot of the wealth and a lot
of the people in the world are
distributed in the places where there's
really good growing conditions and as
the Earth continues to warm places with
historically really amazing growing
conditions like Central California could
become lifeless hellscapes and that
would be a perfect habitat for zombies
but not so good for cabbages and
strawberries and by the time we reach
something as subtle as a 3° increase in
global temperatures which scientists say
could happen as soon as 2100
Saskatchewan could be the next Central
California and all of the Fertile
cresant of the world may stop bringing
forth their marvelous Bounty and what
always comes along with poor growing
conditions in drought well you get
famine and you also get his brother
Horsemen war in case you didn't hear
back in October the human population hit
7 billion people and every single one of
them wants to eat food and when people
get really hungry they start to hurl
little hunks of metal through each
other's bodies which is one of my least
favorite recreational activities of
humans so famine is pretty scary and so
is number three which is displacement
and mass extinctions due to sea level
rise so you've probably heard of this
one because it affects all the cool kids
like polar bears and people who live in
Brooklyn so it's getting hotter right
and all that precious fresh water that's
locked up in the polar ice caps is
melting so like right now as I'm eating
this hot pocket I have Hot Pocket have
told you I love Hot Pockets there's some
polar ice kep melting and now it just
keeps happening oh thank God that's good
this is why they fake eaten television
shows but screw that so there's enough
water locked up in the ice on our planet
that if it all melted we'd pretty much
all be in some serious trouble here in
the US we can expect to see New Orleans
underwater uh parts of the Bay Area a
lot of New York City but worldwide it's
actually looking a lot worse than that
entire island nations like the
Philippines and Indonesia would lose all
their fresh water supplies and it's
possible that they would need to be
irely evacuated within this Century many
of the largest countries in the world
like Bangladesh Vietnam India and China
all have very high populations living in
very low-lying urban areas and all that
is to say nothing of the diverse and
vital ecosystems that could be
completely destroyed in the event of a
large magnitude sea level rise though I
think Miami would make a pretty sweet
artificial Reef I'm sure the octopi
would love it the acidification of the
world's oceans basically carbon dioxide
is water soluble which means that as the
concentration in our atmosphere goes up
so goes up the concentration in the
ocean so the oceans have a deal with the
atmosphere which is that all the carbon
dioxide that the plants on the earth
don't want the ocean will suck it up for
plants and animals in the ocean to use
and the animals in the ocean use that
carbon dioxide to create their bones and
their shells and their pearls and
whatever and then when they die all that
stuff Falls the bottom of the ocean
becomes rock this is great we're getting
rid of carbon dioxide however when
carbon dioxide dissolves into water
there's a chemical reaction which
slightly lowers the pH of that water and
a lower pH means it's more acidic and
it's not a super huge change but it turn
out that a lot of the animals in the
ocean especially the ones at the bottom
of the food chain really require a very
specific pH so the carbon dioxide gets
dissolved in the water the pH goes down
just a little bit and guess what it's
mass extinction time again which is like
a party except with 70 to 90% fewer
species on the planet I'm sorry are you
doing okay I know this episode's been
kind of a downer but we've only got one
more horrible scary thing to go and
that's shutdown of the global conveyor
belt so unfortunately I don't have time
to get into this topic and all the
detail that it deserves but if you want
to Google it just look up thermaling
circulation the thermohaline circulation
is awesome and it's a huge reason why
our planet can not only support so much
life but also such complexity of Life
basically all of the oceans in the world
are connected together through this
giant conveyor belt and it's driven by
winds and the rotation of the earth and
the different serenities of the ocean
but most of all it's driven by the
difference in temperature between the
Equator and the poles it's impossible to
talk about climate without talking about
the thermohaline circulation because it
affects everything for instance this
conveyor brings water up from the
Caribbean along the eastern coast of
America and then across to England which
is why England turns out to be so balmy
even though it's latitude would suggest
that it would have a climate more like
Canada it also and this is very
important delivers oxygen from the
surface of the Earth down to the watery
depths where all of those extra weird
organisms like anglerfish live that we
don't know very much about in the
history of our planet when carbon
dioxide levels get above a thousand
parts per million this thermohaline
circulation has shut down which is
leading scientists to wonder if this
could happen again and if it does what
could happen oh my God so many bad
things would happen first all of the
weather in the world would change or
stop or something it's unclear exactly
what would happen because all of the
models go totally screwy when you shut
down the thermohaline circulation but
basically it would be dramatic and
probably catastrophic secondly the
oceans of the world would become a big
stagnant puddle except for some of the
stuff that that's living on the very
surface but most of the ocean would
become a freezing black dark deep
oxygenless place like space and third
this massive lack of oxygen at pretty
much every strata of the ocean would
lead to a huge explosion in the
population of anerobic bacteria and
anerobic bacteria uh they like to
produce this compound called hydrogen
sulfide which if you've ever smelled
rotting eggs you are aware of what it
smells like but in a full Thermo alen
shutdown uh it would become a much more
familiar smell because everything would
smell like it the reason why we uh think
it smells so bad is because hydrogen
sulfide is extremely poisonous is one of
the most toxic chemicals that we know of
there would be so much of it that pretty
much all of the animals near the coast
would die and yeah and your friend and
finally would have to put on gas mask
before we go outside so I can't talk
about this anymore because I don't have
time and also because it freaks me out
it is impossible to stress
how this would be so if you're here for
a worst case scenario There It Is
Everything dies and the entire Earth
smells like 20 billion rotten eggs and
guess what that is still not enough to
convince me to stop eating meat and
driving to work and flying to the east
coast to see my family and I have no
idea why that is but I bet that there
are some very smart social scientists
working on that issue right now trying
to figure out why we are all so stupid
and hopefully they'll figure it out soon
thank you for joining us here on side
show you can connect with us on Twitter
or Facebook or right down below in the
comments right here in like pants area
so I pointing at the right place yeah
okay good
