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.

According to backtests from Goldman, since the mid-1980s, significant stock drawdowns (i.e. market crashes) began only when term slope started steepening after being inverted. ...
Powell Keeps The Bond Bull Kicking Written by Lance Roberts | Mar, 21, 2019 In a widely expected outcome, the Federal Reserve announced no change to the Fed funds rate but did leave open the possibility of a rate hike next year. Also, they committed to stopping “Quantitative Tightening (or Q.T.)” by the end of September. 多くの人が予想したとおり、FEDはFFR変更をしないだけでなく来年も不明とした。さらには、QTを9月末に終えると約束した。 The key language from yesterday’s announcement was: 昨日の発表の重要な部分はこういう具合だ: “ Information received since the Federal Open Market Committee met in January indicates that the labor market remains strong but that growth of economic activity has slowed from its solid rate in the fourth quarter . Payroll employment was little changed in February, but job gains have been solid, on average, in recent months, and the unemployment rate has remained low. 「1月のFOMC以来の情報を分析すると、労働市場は強いがQ4に比べると経済成長は鈍化している。2月の雇用環境にほとんど変化がなかった、ここ数ヶ月確実に雇用は増えている、そして失業率は低いままだ。 Recent indicators point to s...

We strongly believe it is poised to fail. The problem for bullish late-cycle momentum investors trying to play a breakout to new highs here is the oncoming freight train of deteriorating macro-economic conditions. 米国株式は記録的バリエーションのもとで再度過去最高を試している。私どもはこれが失敗すると強く信じている。景気拡大終盤で強気のモメンタム投資家が新高値を試そうとしていることの問題は、マクロ経済条件の悪化にある。 US corporate profit growth, year-over-year, for the S&P 500 already fully evaporated in the first quarter of 2019 and is heading toward outright decline for the full year based on earnings estimate revision trends.
