Climate Alarmists Making It Up As They Go Along
Newsweek had another delusional and alarmist piece this week, this time on Antarctic sea ice.
Reporting, apparently, on a study in Current Biology, they say:
In Antarctica, the movement of icebergs is seasonal. When winter hits, the sea surface freezes, locking icebergs into place and preventing them from colliding on the seabed—where most Antarctic species live. For at least the last half century, however, global warming has led to a dramatic decline in this winter ice, meaning there are more glacial collisions, known as “scouring,” on the Antarctic seabed. In a Current Biology paper published Monday, scientists argue that this increase in scouring might negatively alter how species on the shallow portion of Antarctica’s seabed interact with one another—and they worry this is a harbinger of climate change–linked ecosystem changes around the globe.
I say “apparently”, because it is hard to see “scientists” making such a catastrophic error, or that peer review did not pick up on it. In any event, let’s review the facts.
We know that far from “dramatically declining”, Antarctic sea ice has been expanding since satellite measurements began in 1979. This expansion has happened in winter, as well as other seasons, as the official NSIDC data tells us.
The article specifically mentions the Antarctic Peninsula, but even here winter sea ice has been above normal.
