"We replaced the stove with plywood, turning the kitchen of the dive boat into
an impromptu research lab. Plugging in wires and connecting tubing, we
assembled a scientific instrument within the cramped cabin.
Then we cast off into Halifax Harbour, Canada, surveying the turquoise waters
for signs of an unusual test: could we use the ocean itself to remove carbon
dioxide from the air?
Carbon dioxide (CO₂) is the most important driver of climate change, but it
cannot be seen. Its build-up in the atmosphere is gradual. Its worst
consequences take time to emerge. Even if emissions fell sharply tomorrow, the
CO₂ already released would continue to warm the planet.
That is why scientists and policymakers are increasingly turning to carbon
dioxide removal (CDR): taking CO₂ that has already been released back out of
the air. So far, most large-scale CDR has focused on land, such as
reforestation. But land is finite, competes with food production and
biodiversity, and stored carbon can be lost through fire or deforestation. As
emissions continue to outpace what these approaches alone can manage, attention
has turned toward the ocean."
