As Climate Changes, Sami Herders Need to Feed Reindeer as Rain Creates Ice Layer

Driving slowly on his snowmobile, reindeer herder Nils Mathis Sara spreads animal feed for hundreds of his reindeer gathered in the Finnmark mountain plateau in Arctic Norway - something he wished he did not have to do.

"This is an emergency situation," said the 65-year-old Indigenous Sami herder. "I am not supposed to feed them. They are supposed to feed me."

Normally reindeer find their own food, digging through the snow with their hooves to eat the lichen buried underneath.

But every winter for the past decade Sara has had to buy animal feed to supplement their diet so they can make it through winter, when temperatures can drop to minus 40 degrees Celsius (minus 40 degrees Fahrenheit).

Until recently Finnmark experienced stable, below-freezing conditions, meaning precipitation came as snow only in winter. But in recent years, there have been milder periods, with temperatures rising above freezing.

That means rain, rather than snow, falling on the ground, which then freezes when it gets colder, creating a layer of ice that makes it tough for the reindeer to reach the lichen.

"It is especially hard for the younger reindeer as their hooves are not strong enough to break through," Sara said.

One morning in March when temperatures reached minus 10 C, Sara and his nephew Nils Olav Lango spread 1.6 metric tons of tiny brown pellets across the pastures where the family's herd graze. They have been doing it every other day since February.

"I should really be doing this every day but economically it does not make sense," said Sara.

Feeding the animals also leads to unintended consequences.

Later that day, Sara spots hundreds of reindeer that are not his family's on his district's pastures - each herding group has the right to use a specific area and each keep to their own.

Sara races on his snowmobile to talk to the herder in charge and ask him to move the animals away. They had been attracted by the smell of the feed that Sara had spread.

In addition, feeding the reindeer, which are semi-wild, turns them progressively into fully domesticated animals and thus turns herders into farmers, going against centuries-long Sami traditions.

"When we feed the reindeer, they change their behavior and become more accustomed to humans," Sara said. "This is not our way."

Prolonged droughts, wildfires and water shortages. Torrential downpours that overwhelm dams and cause catastrophic flooding.

Around the globe, rising temperatures stoked by climate change are increasing the odds of both severe drought and heavier precipitation that wreak havoc on people and the environment.

Rainfall can disappear for years only to return with a vengeance, as it did in California in 2023, with record-setting rain and snowfall. That led to heavy vegetation growth that provided fuel for the devastating January wildfires in Los Angeles after drought returned.

But how can global warming cause both drier and wetter extremes? Here's what experts say:

It's all about the water cycle

Water constantly moves between the Earth and its atmosphere. But that system — called the hydrological cycle — is speeding up as global temperatures get hotter, primarily due to the burning of fossil fuels like coal and gas.

A hotter atmosphere sucks up more water vapor from bodies of water and vegetation and soil.

Over land, this atmospheric demand and loss of surface moisture leads to longer and more intense droughts, even causing some arid areas to expand. Though rain falls less often, when it does, it's often in intense and destructive deluges.

That's because the atmosphere holds 7% more water vapor for every degree Celsius.

“Basically, global warming is turning the atmosphere into a bigger sponge so it can soak up more moisture ... and then when the conditions are right for rainfall, it’s like squeezing that sponge,” said Jonathan Overpeck, a climate scientist at the University of Michigan. "You get more moisture coming out faster."

Oceans play outsized role

Oceans absorb most of the planet’s extra heat. That causes the water to expand and ice to melt at the poles, raising sea levels. The warmer water also provides fuel for larger hurricanes and cyclones that can dump massive amounts of water in a short time.

In 2023, for example, heavy one-day rains from Mediterranean storm Daniel caused massive flooding across eastern Libya that overwhelmed two dams, sending a wall of water through the coastal city of Derna that destroyed entire neighborhoods and swept bridges, cars and people out to sea. Climate scientists say climate change made that storm far more likely.

Snowpack is diminishing

Climate change also is affecting snowpack, a critical part of the hydrological cycle.

Melting snow helps fill reservoirs and waterways, including for drinking and agriculture. But less snow is falling in general, and what does often is absorbed by thirsty soil.

What's more, because winters are becoming warmer overall, the growing season is longer, meaning snowmelt also is being lost through evapotranspiration of plants. But, just like rain, climate change also can cause more intense and sometimes damaging snowstorms.

“All this stuff is related to warming, which we know with perfect confidence is almost all due to human activity,” Overpeck said. “The good news is, we know how to stop it if we want to.”
