Por calentamiento global: se quiebra plataforma de hielo Milne en Canadá.
El Servicio Canadiense de Hielo publicó una animación satelital en su cuenta oficial de Twitter, que muestra el colapso de la plataforma de hielo de la región de Milne, en la lejana zona de Nunavut, en Canadá.
Satellite animation, from July 30 to August 4, shows the collapse of the last fully intact #iceshelf in #Canada. The Milne Ice Shelf, located on #EllesmereIsland in #Nunavut, has now reduced in area by ~43%. #MilneIceIsland #seaice #Arctic #earthrightnow #glacier pic.twitter.com/jjs1gawoxA

Un glaciólogo dijo que era solo cuestión de tiempo antes de que se rompiera la última plataforma de hielo intacta de Canadá.
El evento, que comenzó hace una semana, ha reducido el tamaño de la plataforma en un 43 por ciento a 106 kilómetros cuadrados.
A huge section of the Milne #IceShelf has collapsed into the #Arctic Ocean producing a ~79 km2 ice island. Above normal air temperatures, offshore winds and open water in front of the ice shelf are all part of the recipe for ice shelf break up. #MilneIceIsland #Nunavut #seaice pic.twitter.com/fGfj8Me9tA

Derek Mueller, profesor asociado de la Universidad de Carleton, dice que la separación fue inevitable, pero aun así se sintió como si se perdiera a un buen amigo.
Mueller ha realizado varios viajes para estudiar el hielo en la isla de Ellesmere desde 2004 y ha observado su deterioro gradual.
Él dice que, aunque la plataforma de hielo de Milne mantuvo su área hasta hace una semana, había desarrollado grietas y grietas que empeoraron a lo largo de los años.
La pandemia de COVID-19 impidió que Mueller y sus colegas visitaran el Ártico este verano. Colocaron instrumentos de investigación allí en julio pasado y estaban planeando recolectarlos.
Así que hemos perdido no sólo el equipo, que ahora se está alejando en el Océano Ártico, sino también la información que registró durante el tiempo que estuvo fuera, dijo Mueller.
También está a la deriva la investigación de organismos marinos, como esponjas y anémonas de mar, descubiertos en bolsas de agua dentro del hielo.
No estamos seguros de cuáles son estas consecuencias para estos animales. Y ciertamente no estarán donde los estábamos estudiando, porque esa pieza se ha alejado de la orilla, dijo.
Si volvemos a encontrar este tipo de animales, creo que será un golpe de suerte, concluyó.

a lot more useful than ever before.
