A
large and fast-melting glacier in Greenland is growing again, according
to a new NASA study. The Jakobshavn (YA-cob-shawv-en) glacier on
Greenland's west coast had reportedly been retreating by around 1.8
miles and thinning by nearly 130 feet annually in 2012.
"At first we didn't believe it," said lead author Ala Khazendar who
works at NASA's Jet Propulsion Laboratory (JPL). "We had pretty much
assumed that Jakobshavn would just keep going on as it had over the last
20 years."

Co-author Josh Willis said that while this is "good news" on a
temporary basis, it's still "bad news" over the long term because it
means that ocean temperatures are a larger factor in the growth and
melting of glaciers than previously thought.
"In the long run we’ll probably have to raise our predictions of sea
level rise again," says Willis, pointing to inevitable doom from
man-made global warming.
"That was kind of a surprise. We kind of got used to a runaway
system," said Jason Box, a Geological Survey of Denmark and Greenland
ice and climate scientist who was not involved in the study.
Think of the ocean temperatures near Greenland like an escalator
that’s rising slowly from global warming, Khazendar said. But the
natural North Atlantic Oscillation sometimes is like jumping down a few
steps or jumping up a few steps. The water can get cooler and have
effects, but in the long run it is getting warmer and the melting will
be worse, he said.
Four outside scientists said the study and results make sense.
University of Washington ice scientist Ian Joughin, who wasn’t part
of the study and predicted such a change seven years ago, said it would
be a “grave mistake” to interpret the latest data as contradicting
climate change science.
この研究に参加していない4人の科学者はこれは意味のある発見だという。ワシントン大学の氷床研究者 Ian Joughin、彼はこの研究に参加していなかったが数年前にこのことを予想していた、彼が言うには 気候変動科学の矛盾をしめす「決定的な」最新データだという。
What’s happening, Joughin said, is “to a large extent, a temporary
blip. Downturns do occur in the stock market, but overall the long term
trajectory is up. This is really the same thing.” -AP
Of course, what will they say if and when the sun enters a Maunder Minimum in 2020? The last time there was a prolonged solar minimum, it lead to a mini ice-age which was scientifically known as the Maunder minimum SHTFplan.com's Mac Slavo wrote last November that sunspots have been absent for most of 2018 and Earth’s upper atmosphere is responding, says Phillips, the editor of spaceweather.com.
Data from NASA’s TIMED (Thermosphere Ionosphere Mesosphere Energetics
and Dynamics) satellite shows that the thermosphere (the uppermost
layer of air around our planet) is cooling and shrinking, literally
decreasing the radius of the atmosphere. This reduction of solar
activity could result in a global cooling phase.
“The thermosphere always cools off during Solar Minimum.
It’s one of the most important ways the solar cycle affects our
planet,” said Mlynczak, according to The New American.
「ソーラーミニマムのときは地球熱圏はいつも寒冷化する。ソーラーサイクルが地球に与えるもっとも重要な効果だ、とThe New American誌による。
The new NASA findings are in line with studies released by UC-San Diego and Northumbria University in Great Britain last year, both of which predict a Grand Solar Minimum in coming decades due to low sunspot activity.
Both studies predicted sun activity similar to the Maunder Minimum of the mid-17th to early 18th centuries, which coincided to a time known as the Little Ice Age, during which temperatures were much lower than those of today.
文章全体がZeroHedge特有の皮肉で満ちています。 Global Earnings Downgrades At Highest Level In 10 Years by Tyler Durden Thu, 01/10/2019 - 16:45 As stock markets plunged in December, asset-gatherers and commission-takers (and politicians) rushed on to every media outlet to reassure everyone that the fundamentals are "solid", "extremely strong", "very positive" ... pick your spin. The only problem is that top-down, the fundamentals are dismally disappointing... 12月の株式急落で、株式を買い集めている人、手数料狙いの人(そして政治家)はメディアに出ずっぱりで誰もにこう訴えた、ファンダメンタルズは「健全」、「とても強い」、「とてもポジティブ」・・・みなさんもこれに振り回された。唯一の問題はこれらは上意下達であることだ、実際のファンダメンタルズは悲しいかな失望するものだ・・・・ And bottom-up, the fundamentals are almost as bad as they have ever been as analysts take the ax to their outlooks... the number of analysts’ global earnings downgrades exceeded upgrades by the most since 2...
米国はよく理解してませんが、日本の場合では量的緩和で日銀が国債買い上げした資金は日銀当座預金にそのままです、市中には流れていません。でもNHKのニュース等では「ジャブジャブ」という表現をアナウンサーが使い、さらに丁寧に水道の蛇口からお金が吐き出される画像まで示してくれます。これって心理効果が大きいですよね。量的緩和とは何かを7時のニュースや新聞でこれ以上丁寧に解説するのはそう簡単ではありません。一般の人も株式をやっている人も「イメージ」で捉える以上はそう簡単にできません。多くの人は量的緩和とはなにか、を理解していないと私は想像しています。 ただし、国債を買い上げるので長期金利が低下し住宅ローン金利等が下がったのは確実な効果です。一方で長短金利差が少なくなると銀行のビジネスモデルが成り立たなくなりますが。 This Is The One Chart Every Trader Should Have "Taped To Their Screen" by Tyler Durden Sat, 01/19/2019 - 18:55 After a year of tapering, the Fed’s balance sheet finally captured the market’s attention during the last three months of 2018. 一年間のテーパリング後、FEDバランスシートがとうとう市場の注目をあびることになった、2018年の最後の3ヶ月だ。 By the start of the fourth quarter, the Fed had finished raising the caps on monthly roll-off of its balance sheet to the full $50bn per month (peaking at $30bn USTs, $20bn MBS...
