re "The active layer can be deduced from the size of the trees as they need deep roots to not fall over, and to get at the water they need in summer."

Trees growing in a thin active layer over permafrost have shallow plate-like root systems, not deep tap roots.

re "What matters is air temperature. That has been monitored for 100 years fairly well and very well for 40 years and pretty good for a few hundred years with less precision, but well enough to know about medieval warming, Mongol success, Greenland success, Maori migration to the freezing south (not so freezing in warmer climate). Over the last 50 years there actually has not been the expected tropospheric heating that the simplistic Greenhouse Effect so-called Settled Science predicted."

So what is causing the rapid temperature rise in the arctic permafrost? Could it be absorbing that excess heat out of the troposphere?

North Slope permafrost thawing sooner than expected

"The temperature of permafrost is rapidly changing," said Vladimir Romanovsky, head of the Permafrost Laboratory at the University of Alaska Fairbanks Geophysical Institute.

"For the last 30 years, the mean annual ground temperature at the top of permafrost on the North Slope has been rising," Romanovsky said. The mean annual ground temperature—an average of all of the years' highs and lows at the Deadhorse research site—was 17.6 degrees Fahrenheit (minus 8 degrees Celsius) in 1988, and now it's 28.5 F (minus 2 C). Researchers expect the average annual ground temperature to reach 32 F (0 C), the melting point of ice, in many areas.

"We believe this will be before 2100 at many locations within the North Slope," Romanovsky said.

Indonesia plans to relocate its capital from Jakarta

(CNN) — Indonesia plans to move its capital city from Jakarta, according to the country's planning minister.

Indonesia's Minister of National Development and Planning Board Chief, Bambang Brodjonegoro, said President Joko Widodo favored a plan to relocate the capital from Jakarta to outside of Java Island, according to CNN Indonesia, but that the government has not yet formally decided an exact location.

According to Reuters, Brodjonegoro said on Monday that the administration was considering the eastern side of the archipelago as the destination for the new capital. However, such a move could take up to 10 years, he said,

Jakarta is home to more than 10 million people according to the United Nations, with an estimated 30 million in the greater metropolitan area.
It's also one of the fastest sinking cities in the world, according to the not-for-profit organization The World Economic Forum. The nation is prone to flooding and is sinking at an alarming rate due to over-extraction of groundwater.
Brodjonegoro estimated that government would need the equivalent of 23-33 billion US dollars to move the capital, build new infrastructure and relocate civil servants from Jakarta, CNN Indonesia reported.
