So, when the true “terra australis” was found, they had to come up with a different name. “Arctic” comes from the Greek word arktikos, a reference to arktos, which means “bear”. In the old days (and even today, for those who are willing to skip GPS), people were guided by Polaris (the North Star), which indicates North for those located in the North Hemisphere. Polaris is a star right above the North Pole and, because of that, barely moves in the night sky. To find Polaris, one would only have to identify the constellation Ursa Minor (literally meaning Little Bear) and follow its tail. Therefore, as the Arctic was up in the north, near Polaris, then it was the land near the bear. The fact that the Arctic has polar bears, while Antarctica does not, may or may not be a coincidence.
Partly inside the Arctic Circle, there is Greenland, a huge island permanently covered by ice and with no trees. So, why is it called a land of green? Because it was, thousands of years ago, when the Vikings disembarked there. However, its true name is actually Kalaallit Nunaat, which means “the land of the Kalaallit”. The Kalaallit are the native Indigenous people of “Greenland”. They are Inuit, which means “people” (please note that “Eskimo” is a term European people used to use that is nowadays considered highly offensive). There are different tribes of Inuit. The Kalaallit are the ones from Greenland, or better yet Kalaallit Nunaat. There are also Inuit in Northern Canada and in Alaska. By the way, “Alaska” comes from the Aleut word alaxsxaq, which means “the object towards which the action of the sea is directed”. The Aleut are the Inuit of Alaska.
In the Arctic and in Antarctica there are no Indigenous people, but there are plenty of unique animals. Polar bears can only be found in the Arctic regions and penguins can only be found in cold regions in the southern hemisphere, especially in Antarctica. “Penguin” is a curious word… It comes from the Welsh words pen gwyn, meaning “head white”. In reality, it meant “great auk”, “auk” being a bird similar to the current penguins, but not related. Auks have become extinct in the 19th century. Back in the Arctic, narwhals are a type of whales perfectly adapted to these icy waters. Their name comes from Old Norse nāhvalr, a composition of the words nār and hvalr. This last word means “whale”, the first means “corpse” … but in the sense of having a colour similar to the one a corpse has. Another Arctic whale that was named according to its colour is the beluga. “Beluga” comes from the Russian word belyĭ, which means “white”.
Many other animals have adapted themselves to the extreme cold of the Poles. However, Antarctica, like Kalaallit Nunaat, was once green and warmer. In a continent roughly the size of Europe and Australia combined, there are high mountains like the Alps, glacier-carved valleys, flat plains and even an ocean. Researchers have recently succeeded in starting to figure all this out using technology (read the article “Landscape beneath Antarctica’s icy surface revealed in unprecedented detail”, from the link below). The problem for these researchers is that Antarctica’s landscape is covered by a thick ice sheet, just like Greenland. Ice sheets are similar to glaciers, but the former have a much greater extension. They consist of layers of snow that have not melted. Each layer of snow is compressed by the layers above and turns into a kind of ice-rock. As the snow keeps being added above, the snow-turned-ice-rock below moves slightly and very slowly. That is why glaciers carve valleys and ice sheets find their way to the ocean. Those high ice walls, typical images of Antarctica, are the edge of the ice sheet.
Researchers are studying ice sheets to understand how Antarctica is formed and how it will react to climate change. Essential for them are ships. Yet, these ships are not ordinary ships. They are icebreakers. Icebreaker ships are more resistant than a normal ship and have a special design in order to be able to cut the ice. Without this capacity, the ship may get trapped in the ice. That was what happened to Endurance, the famous ship of Captain Shackleton. Another famous Polar explorer ship is Fram. Fram went both to the Arctic and the Antarctica at the end of the 19th century and the beginning of the 20th century and “lived” to tell the tale. This ship is now “parked” inside a museum, where we can get in and have an idea what it was like to travel inside it. Around it, there is plenty of information about its missions and about other missions during that time.
In the nutshell, there is a lot to discover about Antarctica, about the Arctic, and about Kalaallit Nunaat (Greenland).

The name says it all: lobbyists are people who linger at lobbies of law-making institutions waiting to meet lawmakers to pitch them something (check “The Origins of ‘Lobbyist’” on the link below). This practice began, on a regular basis, in the 19th century and it has been evolving ever since. Now, it is a recognized profession. The European Union has even created a way to officially interact with them, in the name of transparency. The idea is to give an opportunity for everyone to be heard. This means that environmental conservationists have the same opportunity as oil companies to influence lawmakers, for example. Except… oil companies have way more money and the possibility to provide more lucrative advantages. Is it equal? No, definitely not. Besides, in lobbying, the line between presenting arguments truthfully and presenting them using manipulative tactics is very thin. And manipulation usually wins.
A writer is someone who writes, but writing is not as easy as it seems. One has to know the language well enough to not make grammar mistakes and one has to know how to organize the ideas in order to build a logical text that its target audience will easily understand.
Every year on 25th April there is a parade in Lisbon, the capital of Portugal, to celebrate the coup d’état that ended dictatorship in 1974. Since then, this day is called Freedom Day and people walk down Freedom Avenue to celebrate Freedom. So, yes, freedom means a lot to Portuguese people, even for those generations who were born in a democratic regime and never witnessed dictatorship (thankfully!).
However, as stated in a poster in the 2024 Freedom parade in Portugal, “hate speech is not freedom of speech”, meaning, you are free to say whatever you want as long as you respect other people. Insulting, humiliating, dehumanizing, inciting to violence is not freedom of speech.

Long story short, merchants started to make a lot of money. And with wealth, came power. They organized themselves in guilds and companies, like the Dutch West India Company. These guilds and companies were owned by the State, but they acted as they were independent. Wealth increased exponentially, both for the State and the merchants. This led to a shift in the economy and feudalism gave way to mercantilism. In countries where agriculture was not as important, trading became the core business of society. This is what happened in The Netherlands, and which gave rise to the Dutch Golden Age.
So, tourism has been around for a long time. It has evolved and now the possibilities are endless. People go touring for all kinds of purposes all over the world. There are pre-defined tours, but you can also plan your own voyage. Different budgets will provide you different trips to different destinations. For the same destination, you can choose different means of transportation, hotels, services. And, if you can afford it (in terms of money and time), you can replay a Grand Tour of your own making.
Then, people found that they needed a place to store their money, a safe place that is. And what safer place was there than the religious temples, guarded by the gods themselves?… Priests were soon lending money to people and robbery started to happen. Things became more serious during the Roman Empire, when buildings were designated especially for storing money and lending money became a common practice. Everyone could lend money and get it back, usually at very high rates. Those who engaged in such activities in small scales were called “usurers”.
Snow is “rain” when temperatures are below the freezing point (0ºC). If there is no moisture, there is no snow, even when temperatures are really low. For example, in Antarctica, there are vast spaces called Death Valleys where there is no moisture, therefore, no matter how low the temperature is, there is no snow, ever. The level of moisture determines the type of snow and, ultimately, how dangerous it is. The temperature also influences as the ice crystals form differently under different temperatures. This is also true for ice, which, in a way, is a form of snow. Or better yet, snow is a form of ice. The difference is that snow is formed in air (hence, “frozen rain”) and ice is formed on the ground.
