When it comes to climate change, it’s the positive feedback loop that’s so terrifying. Increased use of fossil fuels means more warming. Increasing warming means thawing of the permafrost. The thawing of permafrost means the release of methane, a more potent greenhouse gas that causes more warming, leading to acidification of the oceans. It goes on and on. This positive feedback loop is certainly responsible for the rate of climate change we are seeing being well in excess of that predicted. The Daily Beast has a new report on stunned scientists worried about the so-called Doomsday Glacier:
Antarctica’s “doomsday glacier” is “retreating” — or collapsing — at a rate that has stunned scientists enough to claim the potential impact “creepy”. Scientists have studied Thwaites Glacier, which is approximately the greatness of florida, to predict the impact of global sea level rise. In a study published Monday in the journal Nature
Geoscientific researchers said the giant mountain is “clinging by its fingernails.” warned sea levels could rise from three to 10 feet if it collapses.
Three to ten feet? The world’s infrastructure is not designed to handle an increase of this magnitude. Imagine how much would be destroyed in cities and ports.
According to Science Daily:
For the first time, scientists have mapped a critical area of seafloor in front of the glacier in high resolution, giving them a glimpse of how fast Thwaites have retreated and moved historically. The stunning images reveal geological features new to science and also offer a crystal ball of sorts to peer into Thwaites’ future. The team documented more than 160 parallel ridges that formed like a footprint as the glacier’s leading edge retreated and swayed up and down with the daily tides.
Thwaites Glacier in Antarctica has the potential to retreat rapidly in the coming years, raising global sea levels by several meters, according to a new study.

The melting of Thwaites Glacier alone, also known as the “doomsday glacier,” could raise sea levels by several feet. In a recently published study, scientists report that glacier melting has accelerated and is now twice the rate of the last decadehttps://t.co/hEiZV1HiuL
