How are the Winter Olympics affected by climate change?
Summary
TLDRThe video compares the 2002 Salt Lake Winter Olympics, which used natural snow, to the 2022 Beijing Olympics, relying almost entirely on artificial snow. Due to climate change, future Winter Olympics may increasingly depend on artificial snow, which is energy and water-intensive, especially in water-scarce regions. This shift raises costs, affects snow quality, and impacts the performance and safety of athletes. Many former winter sports venues are becoming unreliable due to warming temperatures, and the rising expenses and environmental impact pose significant challenges. The video emphasizes the broader effects of climate change on the snow sports industry and the need to address greenhouse gas emissions.

Q & A
What is the primary difference between the Salt Lake and Beijing Winter Olympics?
-The primary difference is that the Salt Lake Olympics used natural snow, while the Beijing Olympics used almost 100% artificial snow due to climate change and erratic natural snowfall.
Why is artificial snow being used in the Beijing Olympics?
-Artificial snow is being used because of the increasingly erratic snowfall in low-lying areas due to climate change, making natural snow unreliable for winter sports.
What are the environmental concerns associated with artificial snowmaking?
-Artificial snowmaking is energy- and water-intensive, requiring over 45 million gallons of chemically treated water in Beijing. This poses issues in regions already struggling with water scarcity.
How does artificial snow differ from natural snow in terms of composition?
-Artificial snow is composed of 30% snow and 70% air, while natural snow is composed of 10% ice and 90% air. This difference impacts how snowboards and skis move on the snow.
What are the risks of using artificial snow for athletes during the Olympics?
-Artificial snow may soften and spray during practice due to rising temperatures, reducing visibility and increasing the chances of skidding and accidents for athletes.
How has climate change impacted the feasibility of Winter Olympics venues over time?
-Out of the 21 venues used since the first Winter Olympics in 1924, only about 10 remain feasible for winter sports today due to warming climates, erratic snow, fog, wind, and rain.
What is the economic impact of winter sports despite climate change challenges?
-Winter sports generate millions of jobs globally and stimulate local economies. They also encourage communities in cold regions to engage socially, despite the challenges posed by climate change.
Which regions are at risk of becoming unsuitable for winter sports in the future?
-Regions in France, Austria, Italy, Japan, South Korea, Germany, and Russia are becoming less reliable for winter sports, with some areas potentially becoming snowless soon due to climate change.
What is the cost implication of using artificial snow for the Beijing Winter Olympics?
-The use of artificial snow has significantly increased the overall expenditure of the Beijing Winter Olympics, which is estimated to be over $3 billion.
Why is the increasing use of artificial snow a concern for the future of winter sports?
-The increasing use of artificial snow raises concerns about sustainability, costs, and accessibility, making winter sports more expensive and exclusive, which could limit participation from newer talent.
Outlines
ποΈ Natural vs Artificial Snow at the Winter Olympics
This paragraph contrasts the Salt Lake Olympics, which used natural snow, with the Beijing Olympics, which rely almost entirely on artificial snow due to the impacts of climate change. The text highlights how the need for artificial snow is growing as global warming causes snow to become less predictable in lower altitudes where winter sports are typically held. It also discusses the environmental and financial consequences of creating artificial snow, especially in water-scarce regions like Beijing, making future winter Olympics more resource-intensive and costly.
π The Declining Feasibility of Traditional Winter Olympic Venues
Here, the paragraph explores how global warming is affecting the viability of winter sports venues, noting that out of the 21 sites used since the first Winter Olympics in 1924, only about 10 are still reliable for such events. Factors such as unexpected weather changes, including fog, wind, and irregular snowfall, make some traditional locations unsuitable. It further explains how even iconic sites like Chamonix in France have become dangerous for sports, with regions in Germany, Russia, Japan, and South Korea also at risk of becoming snowless.
βοΈ Differences Between Artificial and Natural Snow
The text goes into detail about the physical differences between artificial and natural snow, noting that artificial snow consists of 30% snow and 70% air, whereas natural snow is 10% ice and 90% air. This change in snow composition affects how snowboards and skis perform on artificial snow, with unpredictable outcomes for athletes during practice. The paragraph hints at the challenges this could pose for competitors and event organizers alike.
πΈ Rising Costs and Risks at Winter Olympics
The paragraph discusses the economic burden artificial snow places on the Olympics, estimating costs to exceed $3 billion for Beijing. Additionally, it outlines the dangers posed by warming temperatures, which can soften artificial snow, leading to reduced visibility and higher risks of accidents for athletes. It emphasizes how the rising temperatures during events could directly affect the safety and success of winter sports.
β οΈ Broader Impacts of Climate Change on Winter Sports and Communities
This final paragraph reflects on the broader societal implications of climate changeβs effects on winter sports. While the loss of winter sports may seem less urgent compared to other climate-related disasters, these sports are crucial for creating millions of jobs and driving the global economy. The paragraph also highlights their role in promoting community engagement, especially in colder regions, stressing the need for action to curb greenhouse gas emissions to preserve these activities for the future.

Transcripts
these are pictures of two winter
olympics
what is the difference between the two
the salt lake olympics were held 20
years ago and conducted using natural
snow whereas the beijing olympics are
being conducted by using almost 100
percent artificial snow
as the climate crisis becomes more
aggressive this could become the norm
for future olympics
according to researchers this exercise
is energy and water intensive
in a region that is already struggling
with water scarcity over 45 million
gallons of water is being chemically
treated to generate snow in beijing the
need for artificial snow came about as
snow became more erratic in low-lying
areas where snow sports are practiced
warming induced by climate change is
putting the snow sports industry across
the world at risk forcing governments to
resort to artificial solutions this
makes the activities more expensive
exclusive and closed to newer talent
out of the 21 venues used since the
first shamuni's winter olympics held in
1924 only about 10 are feasible for
winter sports now the unreliable venues
are likely to be affected by unexpected
fog and wind erratic rain and difficulty
in practice and rehearsals since snow
will not be easy to come by
sharmonis itself is deemed dangerous for
winter sports apart from cities across
france austria and italy competition
venues in germany russia were deemed
unreliable from the start by researchers
regions in japan and south korea might
become snowless soon as rain replaces no
precipitation artificial snow is 30 snow
and 70 air whereas natural snow is 10
ice and 90 percent air
this will change how snowboards will
move on snow since the snow is
artificial it is hard to say how it will
react once the athletes start practicing
on it
this also increases the expenditure of
the games estimated to be over 3 billion
dollars
but the major problem is that the
temperatures are still rising
this will soften the snow and make it
spray during practice reducing
visibility making athletes skid and
increasing the probability of accidents
while it can be argued that threatened
winter sports might be one of the less
devastating impacts of climate change
they are responsible for generating
millions of jobs across the world and
stimulating the economy they also urge
people who live in extremely cold
conditions for months together to step
out and engage with the community
moreover it adds to yet another factor
in the reminders that we already have to
curb greenhouse gas emissions
