Scientists Seriously Alarmed Over Cloud Study Report





‘The most singular of all the things that we have found': Clouds study alarms scientists


This story has been updated.
Every week, there are many new scientific studies published relating to climate change. It is a big field, a multidisciplinary field and a hot field.
Change in observed and simulated cloud amount and albedo between the 1980s and 2000s. a, Trend in average of PATMOS-x and ISCCP total cloud amount 1983–2009. b, Change in albedo from January 1985–December 1989 (ERBS) to July 2002–June 2014 (CERES). c, Trend in ensemble mean total cloud amount 1983–2009 from CMIP5 historical simulations with all radiative forcings (ALL). d, Locations where majority of observations and majority of simulations show increases (blue) or decreases (orange). Black dots indicate agreement among all three satellite records on sign of change in a and b and trend statistical significance (P < 0.05 two-sided) in c. All trends and changes are relative to the 60° S–60° N mean change.

And not in a good way.
The study was led by Ramanathan’s Scripps Institution of Oceanography colleague Joel Norris, though Ramanathan said he was not involved in the work and didn’t know about it until shortly before publication. But Ramanathan said that the study basically confirms that there’s nothing to prevent the world from reaching the high levels of warming that have long been feared — except for our own swift policy actions, that is.

Scientists Connect Massive Die-Off Of Australian Mangroves To Climate Change
“We have seen smaller instances of this kind of moisture stress before, but what is so unusual now is its extent, and that it occurred across the whole southern gulf in a single month. It is a natural process, but nature usually does this incrementally. Not with such severity. We have never seen this before.”

Turkey: Back to Zero Problems with Neighbors?
What went wrong? Factors that contributed to Turkey’s regional isolation included problems with Israel related to Hamas and Gaza, a deadlock with Armenia, and a stalemate in Cyprus. Ankara supported the Muslim Brotherhood in Egypt, but a military coup ousted this new ally. The crisis of the Arab Spring also precipitated the civil war in Syria, leading to major tensions with Moscow and Tehran. By late 2015, the country that once followed a zero-problems-with-neighbors strategy now had zero neighbors without problems.

And there you have our future, visible in the 13th, 16th and 18th century price-revolution waves which preceded ours.
That we have entered an era of rising instability and uncertainty is self-evident.There will always be areas of instability in any era, but instability and uncertainty are now the norm globally.
There is a template for global instability, one that has been repeated throughout history. Historian David Hackett Fischer described the dynamics that generate periods of rising instability in his book The Great Wave: Price Revolutions and the Rhythm of History (sent to me a number of years ago by correspondent Cheryl A.)
In Fischer's well-documented view, there is a grand cycle of prices and wages which turn on the simple but profound law of supply and demand; all else is detail.
As a people prosper and multiply, the demand for goods like food and energy outstrips supply, causing eras of rising prices. Long periods of stable prices (supply increases along with demand) beget rising wages and widespread prosperity. Once population and financial demand outstrip supply of food and energy--a situation often triggered by a series of catastrophically poor harvests--then the stability decays into instability as shortages develop and prices spike.
These junctures of great poverty, insecurity and unrest set the stage for wars, revolutions and pandemics.
