Entry #16: Baby Penguins Washing Up On Distant Shores

 Journal

I read this story a few days ago, and found it extremely sad. Hundreds of dead baby penguins have started washing up on distant shores. It is difficult to imagine what must have been going through the heads of Rio de Janeiro beachgoers in recent months as they have seen hundreds of baby penguins wash up onshore dead. At last count, more than 400 penguins, swept from the shores of Patagonia and Antarctica, have been found dead on Rio de Janeiro’s beaches, reports the AP’s Michael Astor. .. Erli Costa, a biologist at Federal University, has a different theory: He thinks rapidly fluctuating weather patterns, influenced by climate change, may be altering ocean currents and making the seas more treacherous. Since most of the penguins washing up are young, he postulates that they are babies that had just left their nests in search of food — and succumbed to the […]

Entry #4: Antarctic Ice-Shelf In Danger Of Collapse

 Journal

I read an article today that indicates how one of the largest ice-shelfs in the antarctic region is in danger of collapse: Photo From ESA The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk. .. This break-up is puzzling to scientists because it has occurred in the Southern Hemispheric winter and does not have characteristics similar to two earlier events that occurred in 2008, which were comparable to the break-up of the Larsen-A and -B ice shelves. “The scale of rifting in the newly-removed areas seems larger, and the pieces are moving out as large bergs and not toppled, finely-divided ice melange,” […]

Big Trouble In Little Arctic

 Journal

I get a lot of notifications in my inbox daily about scientific rumblings going on in the world, but this one caught my eye this evening. Some recent NASA data in the arctic region seems to point to a huge acceleration in the melting rate of the ice — should the melting continue at its current rate, NASA scientists project that it’s only a matter of years before the arctic might be completely ice free in the summers. An already relentless melting of the Arctic greatly accelerated this summer, a warning sign that some scientists worry could mean global warming has passed an ominous tipping point. One even speculated that summer sea ice would be gone in five years. Greenland’s ice sheet melted nearly 19 billion tons more than the previous high mark, and the volume of Arctic sea ice at summer’s end was half what it was just four […]
