A volcano would fall on Santorini, but it is not known when

Around 1650 AD, the underwater volcano Columbo, in the immediate vicinity of the island of Santorini, Greece, began to erupt violently, causing extensive damage and approximately 70 deaths. This eruption doesn’t even compare to the eruption around 1600 BC, also called the Thera Supereruption, which was classified as a VEI 7 on the Volcanic Intensity Scale (VEI), meaning supervolcano. By the way, the maximum VEI is 8.

A recent study, signed by an international team of experts and published in the journal Geochemistry, Geophysics, Geosystems, tells us that a huge bag of magma, previously undiscovered, has just been spotted beneath the Columbo volcano. And this significantly increases the risks of a potential volcanic eruption in the near future.

Don’t despair, it won’t be another supervolcano, but it won’t be good for the residents of Santorini either. According to experts, the volume of already accumulated magma is 1.4 cubic kilometers. In 150 years, it will reach 2 cubic kilometers, which is equivalent to the eruption of 1650 AD. The fact is that although the volume of magma can be estimated, no one can say when a future eruption will occur.

If it does happen, then it will be of an explosive type, information is provided by the characteristics of the magmatic system there. In the same vein, the eruption will be similar to the recent eruption at Hunga Tonga-Hunga Haapai, only having a volcano seven kilometers from Santorini and only 500 meters deep could have dramatic consequences for those there.

The Amazon ecosystem has almost reached the point of no return

As today is the 13th, it looks like we only have bad news. And one of them comes from the journal Nature Climate Change, which tells us that deforestation in the Amazon forest is so advanced that the ecosystem there is on the brink.

In fact, forests released more carbon dioxide than they absorbed. And this is obviously not good at all. This is not beneficial to anyone, not only Brazilians, Peruvians and others who unknowingly cut down the forest there.

The guys who cut down the forests did not understand that their actions would have incredible global consequences. Everything on this planet is interconnected. And the irreparable destruction of an ecosystem like the Amazon will lead to a true domino effect with catastrophic consequences.

It has already been proven that due to destruction in the Amazon region, the level of precipitation in Tibet or Antarctica has significantly decreased. The lack of precipitation combined with global warming, at least in the Tibetan area, means shrinking glaciers and, consequently, water sources that feed the great watercourses of South Asia. We don’t even mention what the lack of precipitation and melting glaciers in Antarctica or the Arctic means.

If immediate action is not taken, the consequences will spread across the globe, leading to severe droughts, destruction of coral reefs, and more. You get the idea, it will be great.

For 250,000 years, dads tend to be older than moms

By studying the genetic mutations that have occurred in the human body, combined with data from thousands of children around the planet, several researchers at the University of Bloomington in Indiana were able to reproduce a statistical model to track the average age that people reach to reproduce. And from yesterday to today, but from 250,000 years ago.

So, the average age at which people decide to have children is 26.9 years. In addition, on average, men finished their offspring at the age of 30.7 years, and women – at 23.2 years. And this is a regularity that has been preserved during this huge period of time. In particular, men were always the oldest, and women were the youngest.

It is obvious that there are many factors that could influence the mentioned regularity. For example, the authors of the study indicate that about 10,000 years ago, the age at which procreation declined. And this fact can be translated through the demographic boom from that time with the advent of agriculture.

About 5,000 years ago, the trend reversed, and the average age at which women typically became mothers rose to 28. I repeat, these are statistics, and here we must take into account that the average life expectancy has increased, and more and more women are having children even at an older age. However, the only constant was the age of fathers versus mothers.
