It’s Raining in Antarctica while Trump slashes Climate Science funding

parts of Antarctica are literally beginning to turn green, as scientists there are finding a four- to five-fold increase in the amount of moss growth on the ice continent's northern peninsula.

Even more stunning news comes from Antarctica in a study published in the June 15 issue of the journal Nature Communications which revealed that over an area of West Antarctica, scientists were stunned to find rainfall and a melt area larger than the size of Texas in 2016.

Yes, it is now raining in Antarctica.


Anthropogenic climate disruption has created stunning major developments in the lives of the Earth’s plants and animals over recent weeks.


A recently published paper in the journal Scientific Reports shows how ACD is disrupting the timing of dozens of songbird species. Timing is critical for migratory birds, because if they arrive too late they only get the tail end of the spring’s insect supply and have trouble finding nesting spots and mates. On the other hand, if they arrive too early, they will arrive in temperatures colder than they are prepared to deal with. Yet, ACD is causing spring to arrive earlier in eastern US states and later in the west, disrupting the timing of dozens of bird species.

This is threatening the survival of many species that are currently popular in many people’s backyards. “The long-term concern is that this growing mismatch can lead to population declines,” Stephen Mayor, the study’s primary researcher said in an interview.

Rain in Antarctica----thats nothing. Steven Hawking now says Trump is going to "push the earth over the brink" and turn the Earth into a Venus-like planet where rains of sulfuric acid exterminate all life

All the other leaders of the world must be breathing a big sigh of relief. As long as Trump is getting blamed for everything then the other world leaders are completely off the hook---they don't have to actually do anything to lower CO2 emissions. :lol:

Scientists fear that two crucial anchor points will be lost.


According to Dr. Rignot, the stability of the whole ice shelf is threatened.

“You have these two anchors on the side of Larsen C that play a critical role in holding the ice shelf where it is,” he said. “If the shelf is getting thinner, it will be more breakable, and it will lose contact with the ice rises.”

If the shelf front disconnects from the ice rises, a rapid retreat will be triggered.


Ice rises are islands overridden by the ice shelf, allowing them to shoulder more of the weight of the shelf. Scientists have yet to determine the extent of thinning around the Bawden and Gipps ice rises, though Dr. Rignot noted that the Bawden ice rise was much more vulnerable.

We’re not even sure how it’s hanging on there,” he said. “But if you take away Bawden, the whole shelf will feel it.”

New piece by rs: https://robertscribbler.com/2017/07/11/ ... -recorded/

Antarctica’s 4th Largest Ice Shelf is About to Melt Back to its Smallest Area Ever Recorded

... Antarctica could be tipping toward instability far faster than previously imagined.

... the Larsen C ice shelf is about to shatter off a very large 5,800 square mile ice berg even as several smaller ice bergs also appear ready to form. This event, which is now imminent in the coming days, weeks, or at most, months, will break the Larsen C ice shelf back to its smallest area ever recorded even as it marks a period of increased instability and risk of ice shelf loss.

For recent scientific assessments show that Larsen C is lowering in the water — an indication that the shelf is thinning. Furthermore, when the gigantic, Delaware-sized, ice berg and its smaller siblings break off they will take with them two outer sections of a stabilizing compression arch. The compression arch, somewhat like the arch of a flying buttress, helps to balance structural stresses for the ice shelf.

If it were to be compromised in total, according to glacier scientists like Dr. Eric Rignot, Larsen C would soon be adding its name to the list of various ice shelves around the world that have already fallen due to the warming airs and waters produced by human-caused climate change.

Iceberg twice size of Luxembourg breaks off Antarctic ice shelf

Satellite data confirms ‘calving’ of trillion-tonne, 5,800 sq km iceberg from the Larsen C ice shelf, dramatically altering the landscape


A giant iceberg twice the size of Luxembourg has broken off an ice shelf on the Antarctic peninsula and is now adrift in the Weddell Sea.

Reported to be “hanging by a thread” last month, the trillion-tonne iceberg was found to have split off from the Larsen C segment of the Larsen ice shelf on Wednesday morning after scientists examined the latest satellite data from the area.

The Larsen C ice shelf is more than 12% smaller in area than before the iceberg broke off – or “calved” – an event that researchers say has changed the landscape of the Antarctic peninsula and left the Larsen C ice shelf at its lowest extent ever recorded.

It will be interesting to see where it goes. Right now its Antarctic winter so it is likely not able to move fast through the ice pack, but Atarctic spring starts the melt down there in two months. I hope they track it constantly so I, and other interested people, can see where it goes and how long it takes to melt.
