Experts Predict a Long, Deep Solar Minimum

If you like solar minimum, good news: It could last for years. That was one of the predictions issued last week by an international panel of experts who gathered at NOAA’s annual Space Weather Workshop to forecast the next solar cycle. If the panel is correct, already-low sunspot counts will reach a nadir sometime between July 2019 and Sept 2020, followed by a slow recovery toward a new Solar Maximum in 2023-2026.

“We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak maximum, preceded by a long, deep minimum,” says panel co-chair Lisa Upton, a solar physicist with Space Systems Research Corp.

Sources and Sinks

Re-Blogged From EurekAlert

For the entire history of our species, humans have lived on a planet capped by a chunk of ice at each pole. But Earth has been ice-free for about 75 percent of the time since complex life first appeared. This variation in background climate, between partly glaciated and ice-free, has puzzled geologists for decades.

Now a team of scientists led by UC Santa Barbara’s Francis Macdonald has published a study suggesting that tectonic activity may be the culprit. They found that long-term trends in Earth’s climate are set by the presence or absence of collisions between volcanic arcs and continents in the tropics. The results appear in the journal Science.

“There’ve been a few hypotheses but no agreements as to why we have warmer or colder climates on these very long timescales,” said Macdonald, a professor in the Department of Earth Science.

Yellow Vest Protesters Clash With Police in Paris

By Associated Press – Re-Blogged From CBS

French yellow vest protesters set life-threatening fires, smashed up luxury stores and clashed with police Saturday in the 18th straight weekend of demonstrations against President Emmanuel Macron. Large plumes of smoke rose above the rioting on Paris’ landmark Champs-Elysees Avenue, and a mother and her child were just barely saved from a building blaze.

French police tried to contain the demonstrators with limited success.

One perilous fire targeted a bank on the ground floor of a seven-story residential building. As firetrucks rushed over, a mother and her child were rescued as the fire threatened to engulf their floor, the city’s fire service told The Associated Press. Eleven people in the building, including two firefighters, sustained light injuries, as other residents were evacuated to safety.

Declining Solar Activity

By Bob Hoye – Re-Blogged From WUWT

In the 1990s, solar physicists, Penn and Livingston, called for a long decline in solar activity. This is the case and it is nice to see such work confirmed by events. Solar Cycles # 23 and 24 are the weakest since the early 1900s. The current run of consecutive Spotless Days is out to 33, or 75%, for the year.

The following table shows the record back to the minimum of Solar Cycle # 23 when the count was at 268 days, or 73%, for 2008.

Amid the Dimmest Sun Since 1978 – a Month Without Sunspots

By Anthony Watts – Re-Blogged From WUWT

The sun today is cue-ball blank, a perfect unmarred sphere:

Solar Dynamics Observatory HMI Continuum


The sun has just passed an entire calendar month with no sunspots. The last time this happened, in August 2008, the sun was in the nadir of a century-class Solar Minimum. The current stretch of blank suns shows that Solar Minimum has returned, and it could be as deep as the last one.

The last time a full calendar month passed without a sunspot was August 2008. At the time, the sun was in the deepest Solar Minimum of the Space Age. Now a new Solar Minimum is in progress and it is shaping up to be similarly deep. So far this year, the sun has been blank 73% of the time–the same as 2008.

Are Childless Climate Change Eco-Worriers Modern Day Shakers?

A commitment to not having sex (so no children) ultimately led to the decline of the 18-19th century Shakers as a significant religious movement.

Reconsidering having kids because of climate change? You’re not alone

One in three women under 30 involved in environmental groups are so worried about climate change and the future of the planet they are reconsidering having kids, according to a new survey.

The survey focused on women’s views on climate change ahead of this year’s federal election, and found nine out of ten of them were “extremely concerned” about the issue.

Australia – Lies, Damned Lies, and Statistics

By Chris Gilham, – Re-Blogged From WUWT

Did you know that Australia’s rate of temperature warming per decade since 1910 has increased by 23%?

No? Neither does the Australian public, despite the Bureau of Meteorology several weeks ago releasing a new ACORN dataset of daily temperatures over the past 109 years that significantly rewrites Australia’s climate history.

ACORN 1 (Australian Climate Observations Reference Network – Surface Air Temperature) was released in 2012. The bureau has released ACORN 2 dailies, a total revision that significantly increases the warming trend calculated from the average temperatures since 1910 at 112 weather stations across the country.
