Transcripts
While weβre already feeling the devastating effects
of human-caused climate change,
governments continue to fall short on making and executing emissions pledges
that would help thwart further warming.
So, what will our world look like in the next 30 to 80 years,
if we continue on the current path?
While itβs impossible to know exactly how the next decade will unfold,
scientists and climate experts have made projections,
factoring in the current state of affairs.
This future weβre about to describe is bleak,
but remember thereβs still time to ensure it doesnβt become our reality.
Itβs 2050.
Weβve blown past the 1.5 degree target that world leaders promised to stick to.
The Earth has warmed 2 degrees since the 1800s,
when the world first started burning fossil fuels in mass scale.
Reports on heatwaves and wildfires regularly fill the evening news.
Summer days exceed 40 degrees in London and 45 degrees in Delhi,
as extreme heat waves are now 8 to 9 times more common.
These high temperatures prompt widespread blackouts,
as power grids struggle to keep up with the energy demands
needed to properly cool homes.
Ambulance sirens blare through the night,
carrying patients suffering from heatstroke, dehydration, and exhaustion.
The southwestern United States, southern Africa, and eastern Australia
experience longer, more frequent, and more severe droughts.
Meanwhile, the Philippines, Indonesia, and Japan
face more frequent heavy rainfall
as rising temperatures cause water to evaporate faster,
and trap more water in the atmosphere.
As the weather becomes more erratic,
some communities are unable to keep pace with rebuilding
whatβs constantly destroyed.
Many move to cities,
where they face housing shortages and a lack of jobs.
A resource squeeze is felt in newborn intensive care wards,
as the rising temperature and air pollution
cause higher rates of premature and underweight births.
More children develop asthma and respiratory disease,
and rates balloon in communities regularly exposed to forest fire smoke.
The global emissions added to the atmosphere each year
finally start to level off, thanks to government action,
but itβs decades too late.
We fail to reach net zero in time.
As a result, by 2100 the Earth has warmed another 0.5 to 1.5 degrees.
Over half of our remaining glaciers have melted.
As the sea heats up, its volume increases due to thermal expansion.
Together, this elevates sea level by well over a meter.
Entire nations, like the Marshall Islands and Tuvalu, are uninhabitable
as large swaths of their islands are submerged.
Some islands, like the Maldives,
spend billions building interconnected rafts
that house apartments, schools, and restaurants
that float above its drowned cities.
Resettled climate migrants in Jakarta, Mumbai, and Lagos
are forced to abandon their homes once again,
as rising tides and extreme storms flood buildings and crumble infrastructure.
Overall, 250 million people are displaced.
Some affluent cities like New York and Shanghai attempt to adapt,
elevating buildings and roadways.
Ten-meter-tall seawalls line the citiesβ coasts.
Children learn about extinct sea life which once inhabited the oceanβs reefs,
all of which have vanished thanks to rising surface water temperatures.
Grocery prices skyrocket,
as food and water scarcity touch all communities.
Fruits and products long grown in the tropics and subtropics
rarely show up on shelves,
as intense heat waves paired with increasing humidity
make it deadly for farmers to work outdoors.
Unpredictable heatwaves, droughts, and floods
cripple small-scale farmers in Africa, Asia, and South America,
who previously produced one-third of the worldβs food.
Hundreds of millions of people are pushed into hunger and famine.
Climate predictions can feel overwhelming and terrifying.
Yet many of the experts responsible for these assessments remain optimistic.
Since countries have first begun taking steps to lower their emissions,
warming projections have shifted downwards.
In less than a decade, weβve reduced our projected emission rates
so that weβre no longer on track to hit nearly 4 degrees of warming.
Policies that invest in renewable energy sources,
cut fossil fuel production, support electric transportation,
protect our forests, and regulate industry
can help mitigate the worst effects of climate change.
But climate experts have also stressed that current policies and pledges
donβt go far enoughβ in speed or scale.
Enacting real change will require bold solutions,
innovations, and collective action.
Thereβs still time to rewrite our future, and every tenth of a degree counts.
