It's finally adrift. When the Larsen C Ice Shelf calved yesterday [Wednesday], it sent one of the largest icebergs ever recorded slipping into a sea frosted with smaller chunks of ice. It marked the end of a decades-long splintering first seen by satellites in the 1960s. The crack stayed small for years until, in 2014, it began racing across the Antarctic ice.
The massive iceberg holds twice as much water used in the United States every year, according to calculations by Peter Gleick of the Pacific Institute. It weighs about 1.1 trillion tons and measures 2,200 square miles. Its volume is twice that of Lake Erie.
"The iceberg is one of the largest recorded, and its future progress is difficult to predict," said Adrian Luckman of Wales' Swansea University, who led a project tracking the crack since 2015. "It may remain in one piece but is more likely to break into fragments. Some of the ice may remain in the area for decades, while parts of the iceberg may drift north into warmer waters."
By mass, the iceberg accounts for 12 percent of the Larsen C Ice Shelf. It's large enough that maps will have to be redrawn. Larsen C was the fourth-largest ice shelf in the world. Now it's the fifth.
In this particular political moment, the calving of a major iceberg has made headlines around the world. Environmental groups connected the event to climate change and the Trump administration's withdrawal from the Paris climate accords. But scientists have cautioned that the story of the iceberg, which will be known as A68, is more nuanced. Climate signals are not clear enough to attribute the event to rising levels of carbon dioxide, but human activity may have contributed to its calving nonetheless.

if you don't remember the break-in and tape-alterations -- only caught due to multiple backups elsewhere! -- there have been those who used original measurements before the newer breed who can only use the altered data because grants. .. so anytime we talk about our influence on weather, or conclusions and recommendations derived from altered data it helps to know that one's being played.
not that these scientists will get any more attention than those documenting how jet-fuel could not have burned hot enough to crash the towers, but hey, at least grab the pdf and check out the people who signed it.

Be careful with your “authors” particularly when one of them [wikipedia.org] signed a declaration that says:
He doesn't believe in climate change because of Theological reasons... To me that is enough to disqualify any “scientific” research he does, regardless of his credentials.
If he is on the side of Science he can't claim God's providence as proof of anything.
Of course, some people will believe anything said by a person whose name is prefixed with Dr.

Give it a few more years, and something will be obvious:
- If global warming is false and they are fudging the past data to fake a warming trend then in few years they are going to have the early 1900's as below zero on the equator.
- If global warming is true and they are not fudging the past data then the warming will be severe and obvious.
I think the most likely possibility is that global warming is real but less than claimed AND they are fudging the past data.
The current apparent pause in the warming could be due to lowering the early measurements and inflating the nineties/oughties measurements to make the curve look steeper.
