The effect of volcanoes on climate and climate on volcanoes

I have always been interested in the impact volcanic activity has on climate change, especially the Little Ice Age. This post by Javier answers a lot of my questions. Bottomline in this quote:

“The solar-LIA remains the only hypothesis supported by evidence, even if we do not understand well the climatic response to reduced solar activity.”

Watts Up With That?

The effect of volcanoes on climate

The relationship between volcanoes and climate is a very complex one. From reading the media one gets the impression that they are some sort of climatic wild card. They are used to explain the cooling after the Pinatubo eruption, or the Little Ice Age cooling as a detriment to the solar hypothesis. But they are also used to explain the warming leading to mass extinctions in the distant past.

To be able to fulfill such a dual role, scientists take advantage of the different gas emissions from volcanoes. About 50-90 % of the gas emitted by volcanoes is water vapor. The rest is highly variable from one volcano to another, but CO2 can be 1-40 %, SO2 1-25 %, H2S 1-10 %, and HCl 1-10 %, plus a lot of other minor gases. H2S gets quickly…

Sunspots Vanishing Faster Than Expected

Dr.Tony Phillips,

Sunspots are becoming scarce. Very scarce. So far in 2018 the sun has been blank almost 60% of the time, with whole weeks going by without sunspots. Today’s sun, shown here in an image from NASA’s Solar Dynamics Observatory, is typical of the featureless solar disk:


The fact that sunspots are vanishing comes as no surprise. Forecasters have been saying for years that this would happen as the current solar cycle (“solar cycle 24”) comes to an end. The surprise is how fast.

“Solar cycle 24 is declining more quickly than forecast,” announced NOAA’s Space Weather Prediction Center on April 26th. This plot shows observed sunspot numbers in blue vs. the official forecast in red:


“Official” forecasts of the solar cycle come from NOAA’s Solar Cycle Prediction Panel–a group of experts from NOAA, NASA, the US Air Force, universities and other research organizations. They have been convening at intervals since 1989 to predict the timing and intensity of Solar Max. The problem is, no one really knows how to predict the solar cycle. The most recent iteration of the panel in 2006-2008 compared 54 different methods ranging from empirical extrapolations of historical data to cutting-edge supercomputer models of the sun’s magnetic dynamo. None fully described what is happening now. [Ephsas Added]

Full Story is HERE.

We live in interesting times when the sun is not acting as expected. That makes every day the sun shines an interesting event. Stay tuned, this is going to be a fun time for solar and cosmic ray observers.

The most important change, however, may be the increase in cosmic rays. Flagging solar wind pressure during solar minimum allows cosmic rays from deep space to penetrate the inner solar system. Right now, space weather balloons and NASA spacecraft are measuring an uptick in radiation due to this effect. Cosmic rays may alter the chemistry of Earth’s upper atmosphere, trigger lightning, and seed clouds.


Are we on the Cusp of the Next Minimum?

26 Apr 2018 – “Worldwide Wine Output Collapses To 60-Year Low, Sparks Fears Of Major Shortage,” says headline.

The Director-General of the International Organization of Vine and Wine, Jean-Marie Aurand, warned that global wine production collapsed in 2017, with a contraction of 8.6 percent compared with 2016. In fact, global wine output dropped to its lowest levels since 1957, primarily due to poor weather in the Eurozone which slashed production across the entire bloc.

In France, vinters reported “widespread damage in Bordeaux, Burgundy, and Champagne, with some losing their entire 2017 crop.

Solar Activity Flatlines: Weakest solar cycle in 200 years

“The good news is that it is highly improbable the sun will enter a Grand Minimum, such as the one that occurred from 1645 – 1715, the period known as the Little Ice Age.” Humm How can they be so sure? How about a Dalton style Minimum?

Watts Up With That?

By Frank Bosse and Prof. Fritz Vahrenholt, No Tricks Zone

In March our supplier of energy was more inactive than in the previous months. The sunspot number was only 2,5, which is only 8% of what is normal for this month into the average cycle (month 112).Only solar cycles 5 and 6 were weaker.

A sunspot was detected only on 6 of 31 days.

Figure 1:  The current solar cycle no. 24 (red) compared to the mean of the previous 23 recorded solar cycles (blue) and the similar solar cycle no. 5 (black).

An observation made on April 10, 2018, allowed us to say that at approximately 30° southern heliospheric latitude the SDO solar research satellite saw a tiny spot (it was too small to be officially counted as a sunspot) that certainly belonged to the next approaching solar cycle no. 25.

Sunspots are magnetic phenomena. The thermally conveyed plasma at the sun’s outer…

A conversation with Dr. Willie Soon – on polar bears, the sun, and Earth’s climate

This is a long question and answer post with a discussion of the Maunder Minimum embedded in the middle by Dr. Soon. He wrote a book which honors the insights of the Maunders, E. Walter Maunder (1851–1928) and Annie Maunder (1868–1947). An interesting read for those following grand minimums. Enjoy

Watts Up With That?

Science, Philosophy and Inquiry on a Galactic Scale

Contributed by Grégoire Canlorbe © 2017 Publised at WUWT by request of Mr. Canlorbe.    These are the opinions of the author and interviewee. 

  • Dr. Willie Soon is an independent solar physicist at the Harvard-Smithsonian Center for Astrophysics who has been studying the Sun and its influence on the Earth’s climate for more than a quarter of a century. A short while ago, he had a conversation with Mr. Grégoire Canlorbe, an independent journalist who is also vice president of the French Parti National-Libéral (“National-Liberal Party,” conservative, nationalist, and free-marketist). Here Dr. Soon speaks for himself. 

Canlorbe: You say polar bears are far less endangered by global warming than by environmentalists dreading ice melt. Could you expand?

Dr. Soon: Yes, indeed. I have argued that too much ice will be the ultimate enemy for polar bears. Polar bears need less sea ice to be…

It appears Solar Cycle 25 has begun – Solar cycle 24 one of the shortest and weakest ever

What, no grand minimum? Based on only one sunspot we are ready to declare SC-25 will be stronger than SC-24? Stay Tuned

Watts Up With That?

Evidence of a Cycle 25 sunspot found

In our previous post: Solar activity crashes – the Sun looks like a cueball, 

Our resident solar physicist, Dr. Leif Svalgaard commented and provided a link to something reported by his colleagues, something that likely would not have been possible without the fantastic solar observations of NASA’s Solar Dynamic Observeratory (SDO). He said:

Cycle 25 has already begun

It looks to me that SC25 will be a bit stronger than SC24, so probably no Grand Minimum this time
(ignore the 2014 in the top line – it is just a place holder).

It seems a small sunspot has been observed, that has the opposite polarity of cycle 24 sunspots.

From the first link at Berkeley, Tomek Mrozek and Hugh Hudson write:

This brief Nugget simply announces that YES, we really have seen Cycle 25 [sunspot activity]. An earlier Nugget hinted at…
