At the poles, more heat radiates out into space than is absorbed from the sun.
Rocket Lab launches NASA cubesat to study heat lost from Earth's poles
"The PREFIRE duo "will criss-cross over the #Arctic and #Antarctica measuring thermal infrared radiation — the same type of energy emitted from a heat lamp — that will make #climate models more accurate and help predict changes caused by #GlobalWarming," Rocket Lab wrote in a mission description."
An iceberg named A-83, 380 sq km in size, broke off the Brunt Ice Shelf in Antarctica on May 20.
"This calving event results from a prolonged weakening of the ice at the McDonald Ice Rumples and progressive eastward extension of the so-called ‘Halloween Crack’ into the ice shelf."
In 2021, the Brunt Ice Shelf produced an iceberg called A-74 followed by an even bigger berg, named A-81, in 2023.
My personal favorite camp on the continent. Fashioned out of a “jamesway” that was used in the Korean War. It’s a little more gritty and DIY than other camps, which gives it its charm and explains why I love it.
The #observatory monitors temperature, water depth, oxygen & chlorophyll levels in the #ocean water. Paired to a #satellite, the observatory transmits #data every 30 mins to #researchers.
Things you probably don't know about me. #1 I love antarctic science and stories. So much that I have pretty much every book written about the heroic age. I also have this. It's a picture drawn by Dr. Edward Wilson, who accompanied Scott on both his polar expeditions. This is a picture drawn by Wilson as a gift to his sister on her birthday in around 1880. I love it! #antarctica#captainscott
NEW STUDY: "#Ocean water is pushing miles beneath #Antarctica’s “#DoomsdayGlacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space to perform an X-ray of the crucial glacier."
"...scientists have estimated 👉its complete collapse could ultimately lead to around 10 feet [3 meters]of sea level rise👈 — a...
...catastrophe for the world’s coastal communities."
"....we have solid observations of what is going on.”
"In a separate study, also published Monday, researchers from the #BritishAntarcticSurvey looked at the reasons for the record low levels of sea ice surrounding Antarctica last year...used #ClimateModels to predict the potential speed of recovery from such extreme sea ice loss and found that 👉even after two decades,...
...the world’s widest glacier and roughly the size of Florida.
It’s also Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice."
Although the #OzoneLayer is on track towards recovery, a hole over #Antarctica appears every year, peaking during September and October, when most biota is protected by snow and sea ice. Unfortunately, as an indirect effect of #ClimateChange, the hole is lasting longer, until well into the summer, damaging biodiversity.
