Keywords

💡Climate Change

Climate change refers to long-term shifts in temperatures and weather patterns, especially those caused by human activities such as burning fossil fuels and deforestation. In the video, it is highlighted as the primary driver of environmental and societal disruptions, with impacts ranging from heatwaves to flooding, affecting both ecosystems and human life.

💡Global Warming

Global warming is the long-term increase in Earth's average surface temperature due to human activities, primarily from the emission of greenhouse gases. The script mentions a current global warming of 1.1 degrees Celsius, which is causing significant impacts on nature and human societies.

💡Ecosystems

Ecosystems are communities of living organisms interacting with their physical environment. The video emphasizes that climate change is impacting ecosystems worldwide, from mountaintops to the deep ocean, causing disruptions in biodiversity and natural services that humans rely on.

💡Extreme Weather Events

Extreme weather events are severe meteorological occurrences that deviate significantly from the average conditions of a specific place and time. The script discusses how these events, such as heatwaves and floods, are becoming more frequent and severe due to climate change, causing widespread damage to both natural and human systems.

💡Adaptation

Adaptation in the context of climate change refers to actions taken to manage or reduce the impacts of climate change. The video script highlights the need for adaptation measures to cope with the changing climate, but also warns of the potential for maladaptation, which can lead to unintended negative consequences.

💡Vulnerable Populations

Vulnerable populations are groups that are disproportionately affected by climate change due to their limited capacity to cope with its impacts. The script points out that the poorest communities, often with limited access to resources, are hit hardest by climate change, living in 'hotspots' across various regions.

Transcripts

all life on earth from ecosystems to

human civilization is vulnerable to a

changing climate

[Music]

scientific evidence now shows that the

current human caused global warming of

1.1 degrees celsius is increasingly

impacting nature and people's lives

everywhere despite efforts to adapt to

the changing climate

[Music]

frequent and severe climate extreme

events such as heat waves over land and

in the ocean droughts and flooding have

caused widespread and pervasive impacts

to ecosystems people

cities and infrastructure and limit the

chances of a livable future for all

there is new knowledge that

human-induced climate change caused

these destructive impacts or makes them

more likely

this report is important because i think

it really underscores the fact that the

scientific evidence is now unequivocal

it's clear that climate change is

impacting on the well-being of human

societies but also on the well-being of

our planet

this report really brings us a new

message though that those two things are

not separate that there's a very

intimate relationship between our

well-being the well-being of our planet

and the forces that are driving climate

change and the resulting impacts and

responses that we may have to that

challenge

since the last assessment report the

scientific evidence has increased and

emphasized based on observations of

impacts

how the ecosystems and human society are

changing under the influence of climate

change we see the losses and damages

and on both sides it we can we have

specific examples that indicate the

underpinning mechanisms

and we are learning from that also for

our projections

as global warming is proceeding what to

expect for the future

and what the future losses and damages

will be

if climate change cannot be stopped

the extent and magnitude of climate

change impacts are larger for each

additional fraction of warming than

estimated in previous assessments

so are the risks projected for the

future

the impacts involve severe and

widespread disruptions to nature and to

society

reducing our ability to grow nutritious

food or provide clean drinking water

[Music]

[Music]

the poorest communities are the ones

that are strongest hit by climate change

as they're least able to cope with the

growing impacts our assessment indicates

that they are between 3.3 and 3.6

billion people who live in such hot

spots these are spread across parts of

africa south asia south and central

america

small islands and the arctic

climate change acts like a stress

multiplier in these regions where people

have limited access to clean drinking

water to sanitation to health facilities

or education

the livelihoods of people are also

strongly dependent on climate sensitive

activities such as farming and fishing

they have limited access to funding

limited accountability from governments

and limited trust therefore in

governments climate impacts are also

felt differentially by men and women as

they have different roles and

responsibilities in society

this report shows that climate change is

impacting every ecosystem across the

globe from high mountain ecosystems to

the deep ocean from

tropical coral reefs all the way to

arctic ice driven ecosystems we see the

fingerprint of climate change across all

of these systems

one of the other things that the report

really shows is that extreme events are

increasing and their effects are

rapidly changing ecosystems across the

globe so marine heat waves heat waves on

land storm events these are driving

changes to the ecosystems and species

that we rely on this is pushing species

towards polar regions it's pushing

species to higher cooler altitudes or

down into the deeper cool waters and

because of that it has cascading impacts

across

ecosystems but also people's livelihoods

and societies that depend on the

services that these ecosystems provide

and as we approach the limits of what

species and ecosystems can tolerate

we risk crossing what we call tipping

points these critical

places in

the system where

returning to previous conditions where

recovery is less possible

climate change impacts are magnified in

cities where more than half of the

world's population lives today

heat waves amplify urban heat islands

and air pollution in cities that affect

people's health

critical infrastructure within

settlements such as transportation

water

sanitation and energy systems have been

compromised by extreme weather events

cities and settlements by the sea are

specifically impacted by climate hazards

they are at the front line of climate

change

being directly exposed to interacting

climate and non-climate coastal hazards

such as sea level rise and destruction

of local ecosystems that previously

protected people living along the coast

multiple climate hazards are also

occurring simultaneously with often

cascading impacts

these impacts are becoming increasingly

complex and challenging to manage

how these will affect nature and people

depends on the speed and level of

warming and how we adapt

the working group to report of the ipcc

shows that

the impact of climate change is worsened

by

destruction of habitats also a

sustainable use of natural resources

deforestation and growing urbanization

and population growth trends

the report also found that

for the african region

increasing urbanization

is an important compounding factor for

climate change

for the coastal areas of africa

especially the low-lying coastal areas

population is increasing rapidly because

of the economic opportunities that the

coastal environment presents

many people moving into the coastal

areas live in informal settlements

marginal areas and high-risk areas

and this

has implications because the threats of

climate change is compounded

and the ecosystems and the people that

rely on them are affected

[Music]

[Music]

we also have evidence of what's called

maladaptation

these are adaptation actions that result

in unintended consequences for example

coastal ecosystems that are destroyed

through the construction of tanks and

sea

all climate related risks that are

transferred to other regions or groups

in society

even greenhouse gas emissions can be

increased through maladaptation

our report shows that indigenous peoples

ethnic minorities and disadvantaged

groups

such as low-income households and those

living in informal settlements are some

of the most affected by male adaptation

unfortunately these reinforces and

entrenches already existing inequalities

the report shows that nature offers

significant yet untapped potential to

reduce climate risks

to deal with the causes of climate

change and to improve people's lives and

livelihoods

however nature needs space and

protection to be able to provide those

services

[Music]

by protecting and restoring thirty to

fifty percent of our world's ecosystems

on land and in the ocean we help plants

and animals build climate resilience

nature in turn can help us regulate the

climate give us clean water control

pests and diseases pollinate our crops

and provide nutritious food

cities also provide a global opportunity

to advance adaptation mitigation and

sustainable development simultaneously

using different adaptation strategies

such as nature based and engineering

approaches together or providing social

safety nets can generate wider benefits

for health food security and ecosystems

however

investing in nature and cities alone

isn't enough to secure a healthy livable

planet for everyone we need to transform

our way of life fundamentally

taking action now gives us the best

chance of

where this success is different is that

it puts our species puts human kind into

context and emphasizes that we cannot

abandon this context because

it emphasizes the relationship between

three systems climate human society and

biodiversity and indicates how all these

systems influence each other human

society causes climate change it causes

biodiversity loss

and these interactions that are

underpinning this

are also the source of the solutions

with

modifying these interactions we can move

into a sustainability space

so i think one of the important

advancements is not only talking about

risk we're looking at the solutions that

we have available to respond to that

risk but a list of solutions is not

adequate what we need to be able to do

is determine the feasibility and

effectiveness of those solutions and how

they might be drawn into practice and so

it really gives practitioners guidelines

about where is the best place to act

we've got very clear pointers for

example to the protection of ecosystems

and activities in cities as ways that we

might be able to change the world

the science is clear any delay in

concerted global climate action means

missing a brief and rapidly closing

window to secure a livable future

this report is a dire warning about the

consequences of inaction it shows that

climate change is a grave and mounting

threat to our well-being and a healthy

planet

our actions today will shape how people

adapt to climate change and how nature

responds to increasing climate risks

it recognizes the interdependence of

climate biodiversity

people and it integrates natural social

and economic sciences more strongly than

earlier ipcc assessments

it emphasizes the urgency of immediate

and more ambitious action to address

climate risks

half measures are no longer an option

ipcc reports provide the most up-to-date

science related to climate change for

policy makers to inform their decisions

on developing climate related

policies hundreds of scientists

worldwide have volunteered their time

and expertise to produce this report

ipcc reports go through an extensive

review process

by expert and government to achieve the

highest quality

this process

makes them policy relevant and policing

neutral
