New solar research raises climate questions

To most of us the Sun seems unchanging, but if you observe its surface, it is seething with vast explosions and injections. This activity has its origin in intense magnetic fields generated by swirling currents in the sun's outer layer.

Scientists call it the solar dynamo. It produces the well-known 11 years solar cycle, which can be seen as sunspots come and go on the Sun surface but models of the solar dynamo have only been partially successful in predicting the solar cycle and that might be because of vital component is missing.

After studying full disk images of the sun's magnetic field professor Valentina Zharkova of Northumbria university and colleagues discovered that the sun's dynamo is actually made of two components coming from different depths inside the Sun.

The interaction between these two magnetic waves either amplifies solar activity or dumps it down.

Professor Zharkova`s observation suggests we are due for a prolonged period of low solar activity.

"We will see it from 2022 to 2053, when next cycle will be very reduced the magnetic field of the Sun. This two waves will not be interacting with each other, which means that resultant magnetic field will drop very dramatically (to 0), and this will be a similar conditions like a Maunder minimum. What will happen to the Earth remains to be seen and predicted because nobody who develop any programs or any models or terrestrial response they based on this period, when the Sun has maximum activity."

She suggests it could be a repeat of the circle Maunder minimum, a period of the 17th century with little solar activity.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
