Feathered ghosts of winter seas
tumble through the tapestry,
flecks of white and pearl
before the blizzard’s blast;
of the Earth.
Shaken by the sky’s frozen rage,
sterile cliffs and barren ground
echo with the silence of the winds –
a stilted sign of storms to come
and those who ride
This poem is inspired by recent research, which has found that entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms.
Climate change can cause extreme weather events that can be harmful to wildlife, including individual animals and entire ecosystems. This is because climate change increases the frequency and intensity of these events. In polar environments, such extreme events can include heat waves, unusual concentrations of sea ice, and severe storms. For example, even though Antarctic seabirds such as snow petrels and south polar skuas, are adapted to harsh conditions, extreme weather events can still impact their ability to breed and other important aspects of their lives. These birds lay their eggs on bare ground, and with enough snow, the ground becomes inaccessible, making it impossible for the chicks to survive.
In this new study, researchers found that climate change caused by increased snowfall has led to significant declines in the breeding success of several Antarctic birds. Svarthamaren and Jutulsessen in Antarctica have some of the world’s largest Antarctic petrel colonies and are crucial nesting sites for snow petrels and south polar skuas. From 1985-2020, there were up to 200,000 Antarctic petrel nests, 2,000 snow petrel nests, and over 100 skua nests annually. However, in the 2021-2022 season, researchers were unable to find a single south polar skua nest, and the number of Antarctic petrel and snow petrel nests dropped to almost zero. The study found that the unusually strong, climate change-induced snowstorms of this year interfered with the birds’ ability to breed, resulting in zero breeding success. The climate crisis means that Antarctic extreme weather events are likely to become more frequent and given that there is clearly already a decline in some critical Antarctic seabird populations, the intensification of these storms could result in their extinction.

Shocking numbers to inform the poem.
Which research link will take me to these numbers, please, Dr Sam? Thanks
I know, it is shocking!

Thanks. I wonder if follow up observations and research has been (is being?) done in 2022/23 on these three bird species, given the failure to breed? Are there any other observed breeding areas for these birds? I’m guessing not…
I think it might be… Maybe keep an eye on the researcher’s webpage?
Thanks. I’ll try and do that.
Great first line!
It is hard to imagine a remote environment where precarious is suddenly magnified to such a harsh degree.
Thanks Valerie. 😊
