Abstract
It
is generally accepted
that the climate
around the globe
is warming. This change in climate has serious consequences for people in general,
but especially for older adults.
Much has been written about the impact of warmer summers, with extreme
heat
and severe weather events impacting morbidity and mortality among older adults. There is far less in the scientific, medical,
and
social literature about the impact of warming winters on older adults. In the northern hemisphere, winters are warming at an
alarming rate, at a much faster rate than summers. There are bigger temperature swings and less frequent but more intense snows.
When there are more days where the daytime
temperatures are above freezing and nighttime temperatures dip below freezing,
there are an increased risks
of falls on ice and transport accidents due to slippery
roads1. Less snow can lead to a reduction of water
in aquifers, lakes,
and rivers as well as drought conditions come spring and summer. Late season heavy
snows can melt quickly
creating spring floods. This commentary seeks to identify some of the
consequences of warmer winters and call for more research on the impacts
of year-round climate
change on older adults.

1. Introduction
Across the globe and across the seasons,
temperatures are rising. There is abundant evidence that average daily
temperatures are rising1-3.
Extreme weather and climate-related events such as fires, floods, and blizzards
have resulted in damage to crops,
deepened poverty, and displaced people
on six continents2. Older adults
are disproportionally affected
by these climate-related
conditions2-5. As the global
population of older adults continues to increase, they are at increasing risk
for the effects of climate
change such as extreme heat and cold, floods,
and droughts3-5.
2. Winters are Warming Rapidly
According to Climate Central (2025), winter
is warming faster than any other season
in the United States (US). Of the 244
US cities they monitor, 98% winter has warmed by an average of 3.9°F
(4.4°C), with the Upper Midwest
in particular warming by an average of 5.4°F (5.2°C)
and some locations warming by as much as 8°F (6.7°C)6. In January, 2026, major cities in the US
set four times more record daily high temperatures than record low temperatures7. Close to 2/3 of monitored locations now
get less snow than they did 50 years ago8.
This reduces mountain snowpack which is a critical
source of meltwater
used to refill reservoirs and irrigate crops in the spring and summer. Shorter winters are known to disrupt summer
crop yields, especially for citrus fruits and nuts. Warmer, shorter winters impact
growing seasons, allergies, and disease-carrying insects6.
In
the United Kingdom,
the intensity of rainfall has increased
by 16% since 18919. They report that while the increase is
seen across all seasons, the winter has been more affected than summer. Warming
winters are such a global concern that the International Olympic Committee is
contemplating moving the Winter Games and Paralympic Games
a month earlier
for better snow conditions
for the athletes10,11.
As winters warm, the planet may
experience less frequent snowfalls, more ice from daily freeze/thaw cycles, and
more extreme storms such as blizzards12.
A blizzard is when snow falls while the winds blow at least
35 miles per hour (56 km per hour), for 3 hours or more12. This causes dangerous whiteout
conditions that present
significant problems for anyone walking, biking, or driving outside, even
after the winds subside. The drifting and deep snow make it harder
for emergency vehicles
to rescue people stranded by the snow.
This is of concern to many older adults.
3. Impact on Older Adults
Although there have been tens of
thousands of articles published within the last 5 years related to climate
change and its relationship to the health of older adults, relatively few have
addressed how changing winter climates have impacted older adults. There are some studies that have examined
how extreme cold events may
contribute to morbidity and mortality4,5,13,14.
For example, Kephart, et al.14 found that in Latin America, a higher proportion of deaths in all age groups were attributable to ambient cold than heat.
Despite these studies,
there seems to be
a large gap in the literature that focuses on how warming
winter temperatures impact the daily lives of older adults.
Beyond morbidity and mortality,
warming winter temperatures impact older adults’ abilities to engage in
occupations that are meaningful to them. These occupations could be recreational, vocational, or related to self-care, each of
which contribute to comfort and well-being of older adults. A few examples can
illustrate this point.
Harsh winter weather, such as
blizzards and extended cold snaps, impacts older adults’ ability to access
food, medical services, and social connections. Older drivers may be hesitant to drive when there is ice on the road. With less snow, historically cold winter climates may
develop more freezing rain that turns into ice. When roads are icy, food
delivery and home health services may not be available, leading to poorer health outcomes.
Friends and family may visit less often resulting in increased feelings
of loneliness, boredom, and isolation. In addition, the vulnerability of older
adults to cardiovascular and respiratory diseases have been noted to increase
mortality under extreme cold temperature and
drastically fluctuating temperatures1,4,5,13,14.
We need more evidence to support these claims.
Skiing is a popular recreational
activity, particularly among adults living in cooler climates or mountainous
environments. Many adults who have skied all their lives continue
skiing well past age 65. Cross-country skiing, snowshoeing, or
snowmobiling may also continue into old age. Older adults who
enjoy these activities may be left with excess time on their
hands when climate change results in less snow. What do older adults do with that excess time?
Ice
fishing is a popular winter
activity enjoyed by many older adults, but it is being threatened
by warmer winters. Warmer winters mean thinner and less stable ice on which to fish. Ice needs to be clear and at least 4” (10.2 cm) to walk on, 12” (30.5 cm) to drive
a car on, but 20” (50.8 cm) to drive a heavy-duty truck with a
wheelhouse shelter15. On many
northern lakes, people need to drive
on frozen lakes to tow their wheelhouse shelter (fish houses on wheels that
often resemble camper trailers) so they can
fish out of the wind, and in some cases,
within heated spaces. The length of the ice fishing
season is shrinking as winters heat up. For many elders in Native communities,
ice fishing is an important source of food, anything that keeps fisherpersons
off the ice is a lost opportunity for obtaining food. What happens when
activities such as ice fishing are not safe because of thin ice?
Older adults who pick up a little
extra income in the winter by driving residential snow removal vehicles are
left without that income when snow doesn’t fall as a result of climate change.
Older adults who work as gig workers delivering people or products on an on-call
basis might have better driving conditions under which to do
their work. If there are prolonged periods where the temperature stays above
freezing, there will be less ice on the sidewalks and trails for walking,
leading to fewer falls and more exercise opportunities. Alternatively, if daily temperatures more regularly cross
freezing (0°C or 32°F),
called zero-crossing days, the freezing and thawing cycle could result in more
ice on the road and create a danger for increased transport accidents
and falls1. We need to know more about how
volitivity in winter weather impacts older adults.
Even for adults who mostly stay indoors in winter, warming temperatures can impact their
daily lives. Outdoor temperature often effects clothing choices. Rapid
temperature swings can make choosing the appropriate clothing more challenging.
The frequency with which an older adult bathes, shaves, or trims one’s hair may also be dependent on outdoor temperatures. The types of foods prepared and eaten also can vary by season.
If a warmer winter leads to a summer drought, that will in turn lead to diminished
food supplies, higher costs for everyday foods, and less food put away for the following winter.
What is the evidence
around food access and older adults in a changing climate?
Additional considerations are the indirect effects
that warmer winters have on the health, vitality,
and comfort of older adults. Warmer winters with less spring
snow melt mean that water supplies are not replenished for spring and summer
growing seasons6. This impacts older adults who farm for a living as well as food supplies for human and animal
consumption. Earlier springs mean that allergy seasons are extended causing
more discomfort for older adults. Warmer
winters also mean that there is less die-off of insects that
carry diseases, increasing vector- borne illnesses in the summer months6. Older adults are more vulnerable to such
diseases than younger adults. With
warming winters, which diseases are
moving into places they were never
found before, and how are older adults affected by them?
4. Call to Action
Given the impacts
of climate change
on older adults,
we need more research
related to the impact of warming and volatility in all
seasons, especially winter.
This research needs to examine the social, health, and economic impacts at the individual,
community, and population levels. Both qualitative and quantitative research
methods are needed to fully understand the
real-life impacts of warming winter climates on the health, vitality, and
emotional well-being of older adults. With
winters warming at a faster rate than summers, we must seek to better
understand how older adults are impacted in all aspects of their life during
these changing winter conditions.
