A climate poem for today: Cantre’r Gwaelod* by Gillian Clarke
UK poet laureate Carol Ann Duffy curates a series of 20 original poems by various authors on the theme of climate change
The morning after, the beach at Borth
is a graveyard, a petrified forest
thundered out of the sand by the storm,
drowned by the sea six thousand years ago
when the Earth was flat,
the horizon the edge of the world.
Remains of stilted walkways tell their story:
how they walked over water between trees,
longing for a lost land when the sea-god stole it,
how they shouldered their children and fled
with every creature that could crawl, run, fly,
till time turned truth to myth.
It’s how it will be as world turns reflective:
seas sated with meltwater, craving more;
a cliff-fall takes a bungalow; a monstrous
tide rips up a coastal train-track;
storm fells a thousand-year-old oak,
smashes a graceful seaside promenade.
Grieve for lost wilderness – for the lovesick salmon,
lured by sweet river-water sleeved in the salt,
homing upstream to spawn at the source
where it was born; for mating hares
in love with the March wind; for thermals
lifting a flaunt of red kites over the wood;
for bees mooning for honey in weedless fields;
for sleepy Marsh Fritillary butterflies
swarming the ancient bog of Cors Llawr Cwrt;
for the Brown Hairstreak in love with blackthorn
and the honeydew of aphids in the ash;
for the blackbird’s evening aria of possession;
for Earth’s intricate engineering, unpicked
like the flesh, sinews, bones of the mother duck
crushed on the motorway, her young
bewildered in a blizzard of feathers;
the balance of things undone by money,
the indifferent hunger of the sea.
*Cantre’r Gwaelod, (The Drowned Hundred) a legendary land lost under Cardigan Bay.
The storms of February 2014 uncovered a petrified forest and evidence of ancient habitation from the beach at Borth.
