For 40 million years we live a glaciation. It is important to remember, first of all.
The monumental scratch that he began to do then ended up freezing an entire continent, today called Antarctica. The North Pole, Greenland’s mountain glaciers and ice appeared much later, “alone” 3 million years ago.
During some of the coldest stages of this Era (glacial periods), an ice crust 30 meters thick covered almost all the land of Europe to France, decimating any form of life.
The last cold stage has lasted one hundred thousand years. It is believed that it was one of the causes that led the Neanderthal Man ahead.
Luckily, these cold stages alternate every several thousand years with more temperate ones (interglacial periods). Homo Sapiens-Sapiens inaugurated the last of these just 12,000 years ago and we are still in this warmer period, which is called Holocene. Even so, it is colder today than when Antarctica formed.
The next thing to come will be another glacier winter. No one doubts that the cycle will stop. It will take a few hundred or a few thousand years, but it will come.
It is therefore appropriate to put the current ice in context, just in case this fear that its volume recedes, has more to do with the bucolic picture of Santa Claus than with the dramatic conditions of life that we would endure if the ice, with capital letters, It is encouraged to come.
Within these last 12000 years, the first 7000 were warm, it is estimated that about 0.5-3º more than now. Since 5500 there has been a slow and progressive decrease in temperatures called Neoglacial, dotted with a few exceptions that have been called «Optimal climate» for housing a temperature suitable for life, as between the I-IV centuries, or between the X- XIV The highlight of this Neoglacial was the Little Ice Age, with three minimums over 1650, 1770 and 1850.
Since 1850, after three cold centuries, the planet recovers temperature, oscillates again towards another «Optimal climate» and it turns out that all this is one of the biggest problems facing humanity.
There are thousands of frontline scientists, including some Nobel laureates who believe that all this is not a problem and seriously doubt their anthropic or anthropogenic (man-made) origin, but we have already seen in the previous post how it is dispatched to any scientific dissent. It’s about you believing that it barely exists, that it doesn’t publish, that it’s paid by the oil companies or that it belongs to the Aznar lobby.
The temperature of the last 150 years has also not been uniform and has mislead about its tendency to such an extent that, only in the 20th century, the media and the “scientific community” have warned of terrible weather forecasts up to four times. Interestingly, two warned of warming and the other two feared a new Ice Age.
In 1912, after a continuous period of 20 years of falling temperatures, the Los Angeles Times published an article predicting nothing less than: “The human race will have to fight for its existence against the cold. The 5th Ice Age is on its way ”
They also looked at the temperature drop for 4500 years (a certain thing) and the following year, on August 10, 1923, an article in The Washington Post already declared: “The Ice Age is coming.”
By 1930, the media recalls and, far from detailing what that Ice Age was like that was already arriving (sic), reactivate the alarm in the opposite direction. There is a danger from global warming: “America in Longest Warm Spell Since 1776” (America in the longest warm period since 1776) stated a New York Times article on March 27, 1933, among many others.
It was true. Since the mid-eighteenth century, with the exception of the minimum around 1850, the planet recovered temperature.
Again, on December 29, 1974, after 35 cold years, The New York Times in an article on global cooling summarized another “consensus” among climatologists:
“(…) The facts of the present climate change are such that the most optimistic experts would assign near certainty to major crop failure in a decade. Mass deaths by starvation and probably in anarchy and violence ”(… The facts of current climate change are such that even the most optimistic experts would grant almost complete certainty to the prognosis of a serious fall in crops in a decade. Mass deaths from starvation and probably in a context of anarchy and violence).
A year later, the same newspaper published: “A serious cooling is widely considered inevitable”
Shortly after, on April 28, 1975, Newsweek magazine announced the almost unanimity of meteorologists in which global cooling would cause “catastrophic famines.”
On May 21 of that same year, The New York Times collected that scientists gave as “well established” that the Northern Hemisphere had been cooling since 1950.
On December 10, 1976, the journal Science warned of the proximity of an “extensive glaciation” in our hemisphere. Two years later, The Day , insisted: “Are we headed for another ice age?” .
It had been 30 years of little explainable cold and a glaciation was feared, because in reality everyone waits for it – according to cycles of 100,000 years – and already “touched us” (sic).
The weather began to warm up in the late 1970s and, at the beginning of the next decade, the alarm, again, was spreading in the opposite direction. Of course, this time with an unusual force.
Since 1895, the media have changed their alarm predictions four times in relation to the weather and although they assured a high degree of probability, the previous three have ended u
