An ancient caterpillar discovered, whose age exceeds 44 million years

An unknown species of an ancient caterpillar, preserved in amber, was discovered by German researchers in the Baltic Sea region in Europe. It is known that the sample found was identified as the larva of a large butterfly species, which was named Eogeometer vadens. The caterpillar, whose age exceeds 44 million years, has a length of 0.2 inches and is the first large fossil butterfly found in Baltic amber.

The oldest caterpillar of the planet

According to an article published on the portal newsweek.com, finds of caterpillars in amber are a rarity in the scientific world due to the predominantly nocturnal lifestyle of most larvae. Having fallen into the trap of resin of an ancient tree, which eventually hardened into amber, the caterpillar waited 44 million years for its discovery, almost completely preserving the details of its structure.

According to the study, the Eogeometer vadens belongs to the Geometridae family of butterflies, whose caterpillars are unusual compared to caterpillars from other groups of butterflies due to the fact that they have only two or three pairs of legs, and not five, the most common number. This reduced number of legs means that they move in a somewhat unusual way.

In addition, butterflies of the Geometridae species are representatives of one of the three largest families of butterflies, containing about 23,000 different species. Most species from this entire family live on trees and shrubs.

According to the researchers, finding a butterfly larva will help to better understand the evolutionary processes that took place during the Eocene, which lasted from 56 to 33.9 million years ago, long before the initial spread of flowering plants. At the same time, scientists note that the discovery of an ancient caterpillar is not the first case in recent months, when scientists announced the discovery of a new species from samples preserved in amber. So, in one of the studies published last month, scientists revealed the existence in the distant past of microscopic creatures who received the unflattering name “mold pigs.” Then unique creatures represented not only a new species, but also a completely new class of invertebrate animals.

Scientists – It is much colder today than in the last 8,000 years

Undisputed temperature reconstructions from around the world show that for much of the Holocene (last 10,000 years), the planet was much warmer than it is today.

Kenneth recently wrote how many new studies of glacier and sea ice sizes show that Iceland is 2-4 ° C colder today than it has been in the past 8,000 years. Only the late 19th century was a little colder.

This post was posted on WUWT and the author provided additional graphics there from other parts of the world showing that the early Holocene was warmer around the world.

First, South America, which shows 100 years ago that it was much warmer from the 1930s to the 1950s than it is today:

Scientists - It is much colder today than in the last 8,000 years 104

Next, we have a 7000-year reconstruction of the Canadian Arctic temperature:

Scientists - It is much colder today than in the last 8,000 years 105

Note that, as many of us already know, the Arctic was much warmer in the early Holocene than it is today.

Finally, let’s take a look at the Swiss Alps, which are 9,000 years old:

Scientists - It is much colder today than in the last 8,000 years 106

Here we see that today it is very cold in the Alps compared to the early Holocene. Old tree trunks found under the glaciers confirm this.

A WUWT reader added that he has “a lot more of this type of graphs, which show very clearly that the whole wolrld has been much warmer for much of the last 10,000 years than it is now.”

And there are really a lot of them!

Medieval warm period, confirmed by hundreds of works

Sebastian Lüning’s remarkable and outstanding Medieval Warm Period reference map, shows hundreds of climatic reconstructions from this period. There we find a lot of research that shows that there is nothing unusual about today’s climate compared to what it was 1000 years ago.

Here are 80 charts from 58 peer-reviewed articles showing the same.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 107

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 108

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.
