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.

🌍 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.

05:01

🌡️ 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.

10:03

🌊 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.

Keywords

💡Climate Change

Climate change refers to long-term shifts in temperatures and weather patterns. It's central to the video's theme, as it discusses the impacts of human activities on the Earth's climate system. The script mentions 'climate change is real' and 'climate change is coming to blow up your house and eat your dog' as a hyperbolic way to emphasize its seriousness.

💡Global Warming

Global warming is the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases. In the script, it's tied to climate change, with the speaker noting the rise in average global temperatures and its consequences, such as the melting of ice caps.

💡Greenhouse Gases

Greenhouse gases are gases in the atmosphere that trap heat, leading to the greenhouse effect and global warming. The video script mentions carbon dioxide, a major greenhouse gas, and how human activities like burning fossil fuels contribute to its increase in the atmosphere.

💡Carbon Sinks

Carbon sinks are natural or artificial systems that absorb more carbon dioxide than they release, thus mitigating climate change. The script discusses how humans destroy natural carbon sinks like the Amazon rainforest, which is crucial for absorbing CO2.

💡Deforestation

Deforestation is the removal of trees and forests, which not only destroys habitats but also reduces the planet's capacity to absorb CO2. The video mentions deforestation in the context of replacing rainforests with cattle farming, which contributes to greenhouse gas emissions.

💡Sea Level Rise

Sea level rise is the increase in the volume of water in the world's oceans, leading to a rise in sea levels. The script discusses the impact of global warming on polar ice caps, which, when melted, contribute to sea level rise and threaten coastal cities and island nations.

💡Ocean Acidification

Ocean acidification is the decrease in the pH of the ocean over an extended period, caused by its increased absorption of carbon dioxide from the atmosphere. The video explains how this process can lead to mass extinctions of marine life, as the script mentions the impact on creatures that depend on a specific pH level.

💡Thermohaline Circulation

Thermohaline circulation, also known as the global conveyor belt, is the large-scale ocean circulation that distributes heat and nutrients throughout the world's oceans. The script briefly touches on this concept, suggesting that disruptions to this circulation could have drastic effects on climate and marine life.

💡Famine

Famine is a widespread scarcity of food, leading to extreme hunger and starvation. The video connects climate change to potential shifts in growing conditions, which could lead to food shortages and famine, particularly in regions that are heavily populated and dependent on agriculture.

💡Displacement

Displacement refers to the forced movement of people from their homes, often due to environmental or political factors. In the context of the video, displacement is linked to climate change impacts such as sea level rise, which could force people living in coastal areas to relocate.

💡Mass Extinctions

Mass extinctions are events that lead to a significant loss of biodiversity over a relatively short geological period. The script discusses how climate change, through processes like ocean acidification, could trigger another mass extinction, affecting a large portion of the planet's species.

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
