Ice reflects 70% of the sun’s heat back into space, while open ocean reflects just 7%.
The more that melting exposes the sea, the warmer it gets and the more melting there is.
Summer sea ice could be gone as early as the 2030s and scientists worry that the heat boost could push the climate beyond catastrophic and irreversible tipping points.
In January and February, the pumps ran for a total of 1,080 hours,
icing over a square area about 450 metres on a side.
Th…

The team had braved temperatures of -40C on the sea ice
to drill holes and pump 50,000 tonnes of ocean water up on to its surface.
It froze almost immediately,
thickening the
1.5-metre-deep ice by about 50cm, according to new measurements.
That has protected the ice, at the start of the melt season at least,
and is an early sign that one day, perhaps, it may be possible to refreeze a significant part of the Arctic.
The ice-thickening process gets a …

Hi. You've reached the level cap of cuteness for today. You can turn off the internet now. 😌

Three dogs are on a sandy beach at the ocean's edge, all leaning in to intently sniff a horseshoe crab on the sand. Two of the golden-colored dogs are wearing rear-wheel dog wheelchairs, which support their hindquarters and allow them to stand on their front legs. A third, black-and-white dog stands to the left without a wheelchair but wearing a harness. All three dogs are clustered together, focused on the large, brownish shell of the horseshoe crab. The background features a wide beach, the o…

Continuing the #PrideMonth 🏳️‍🌈 theme of featuring queer artists, here is “Closer” by Canadian twins Tegan and Sara. I love this 2013 synth-pop banger about desire, and I also love that they use their platform to advocate for

For much of his career, Bruce Menge assumed he would conduct the same research until he died.
The marine biologist has studied sea stars since the 1970s, and the animals had always seemed more solid a bet than others in the ocean.
They have no natural enemies,
regenerate limbs when they lose them
and reproduce prolifically.

Then, just over a decade ago, a mysterious disease wiped out 90 percent of the West Coast’s sea star population.
Tide pools emptied…
