LineageOS 23 brings Android 16 to a wave of abandoned mobile phones, with more difficulties than ever. Google put a wall in the way

by

There is a feeling of betrayal that runs through the most veteran Android community. The reason is Google’s strategy, which has been closing a system that was born completely free: the development of AOSP (the source code of Android) now it’s more privateand the publication of the source code suffer delays that didn’t happen before. While many feel that “the soul of Android has disappeared”the community responds. And the biggest banner of that Open Source resistance has just been updated. In the image, Murena’s /e/ OS alternative ROM, which is based on the popular LineageOS Lifesaver for an abandoned mobile. The life cycle of an Android smartphone is usually not as long as the competition, although that is changing in recent times. From this premise, alternatives emerged such as LineageOS, which is actually the spiritual heir to the mythical CyanogenMod. For many users, it is the only way to have the latest version of Google’s OS and extend the useful life of their devices. LineageOS 23 expands. The LineageOS team has announced a new batch of devices that receive official support for LineageOS 23, its version based on Android 16. This update not only brings the news of Android 16, but also self-developed improvements. For example, “Catapult” and “Aperture 2.0”. The first is a new launcher for Android TV with a clear objective: replace the Google TV interface with a clean, fast and ad-free one. Instead, Aperture is the ROM’s camera app that has now been rewritten from the ground up with support for Ultra HDR and RAW capture. Google has changed the rules. The LineageOS team has confirmed on their official blog that this has been a complicated launch. As we have been saying, the more closed development of AOSP and the fact that Google no longer publishes the Pixel code with total transparency, has caused Google phones to no longer be as easy to support compared to those of any other manufacturer. Despite the difference with respect to the extinct Nexus, the Pixels have been the reference for Open Source development. That’s over too. Consequences. The change in strategy has materialized in delays to the Android 16 code: Google released Android 16 QPR1 for the Pixel (first quarterly update) but never published the source code on AOSP. For this reason, LineageOS has been forced to launch its version 23.0 based on the initial version of Android 16. In practice, ROM users do not currently receive news as notable as the Material 3 Expressive redesign. There are also uncertainty regarding security. Google has changed the way it releases system security patches. They are no longer monthly and complete; most corrections are now quarterly. For its part, the team behind LineageOS warns that this means that its ROM security patch levels could inevitably be delayed. The basis of Android “resistance” without Google. Despite all these difficulties, LineageOS continues to be one of the pillars of the “degoogleized” community. Not only is it an alternative view for the end user, but its AOSP code serves as the basis for privacy projects like the popular GrapheneOS either the European /e/ OS. Keeping LineageOS alive is keeping alive the possibility of an Android without Google in an increasingly controlled ecosystem. New devices. The latest batch of devices that join the official support of LineageOS 23 focuses, curiously, on the Google family and flagships from OnePlus and Xiaomi. Some of them are the Pixel 6, 7, 8 and 9 series, the OnePlus 13 or the Redmi Note 9 Pro 5G. They add to the long list of those that debuted when LineageOS 23 was released a few weeks ago.

A giant wave is sweeping across the Milky Way. Scientists currently don’t know why.

by

Our galaxy, Milky Wayis far from a quiet place. It spins, it wobbles and, as a new study just revealed, it also undulates. New ESA data have discovered a colossal wave, baptized as “the great wave” that propagates through the galactic disk in a very similar way to the waves that we have in a pond when we throw a stone. The study. This phenomenon, which has been identified by the team led by Eloisa Poggio of the Istituto Nazionale di Astrofisica in Italy, is a “corrugation “large-scale vertical” that is superimposed on the already known deformation that our galaxy constantly suffers. In essence, we are facing a wave that causes entire stripes of stars to move “up” and “down.” Great proportions. It is nothing like the waves that we see on our beaches, of course, since we are talking about something on a galactic level. In this case, astronomers know since the 50’s that the disk of the Milky Way it’s not flatbut rather it is deformed (or “warped”) at its edges. Now this study adds an additional structure that no one knew was there. Thanks to Gaia’s incredibly precise measurements, which map the 3D position and 3D motion of stars, the team was able to analyze two populations of young stars: giant stars and classical Cepheids. These maps revealed a gigantic wave that is now coming to light. The figures. In order to understand the magnitude of this phenomenon, we can take into account the following parameters of this phenomenon: Height: the movement of the stars is about 150-200 parsecs, which is up to 650 light years above and below the galactic plane. Length: The structure spans at least 10,000 light years and possibly up to 20,000. Location: affects a vast section of the outer disk, in regions located tens of thousands of light years from the galactic center. The test. The most fascinating thing about the discovery is not just the shape of the wave, but the evidence that it is moving. “What makes this even more compelling is our ability, thanks to Gaia, to also measure the motions of stars within the galactic disk,” explains Poggio. To understand it, the team used a perfect analogue: the wave of a stadium. If we were to freeze the wave that is made in the stands of a stadium, we would see some people standing (the crest), others who have just sat down (the back part) and others who are about to get up (the front part). Something similar happens in the galaxy. The astronomers discovered that the stars with the highest vertical position (the crest) were not the same as the stars with the highest vertical velocity. The maximum speed point was displaced, with a 90º approach phase difference. This phase difference is irrefutable proof that it is a propagating wave. And not only that: the stars inside the corrugation also show a systematic radial motion of 10-15 km/s outward. The conclusion is clear: it is a wave that travels from the interior of the galaxy to its furthest reaches. There is a mystery. Researchers have measured the wave, but don’t know what caused it. The main hypothesis is that the Milky Way suffered an encounter or collision with a smaller dwarf galaxy, but it is not 100% certain. Previous simulations have shown that interaction with a satellite galaxy, such as Sagittarius, can excite exactly these types of vertical waves and corrugations in the galactic disk. This “big wave” is much larger and located much further away than the famous Radcliffe wavea filament of gas about 9,000 light years long located near our Sun. Although both are undulations, scientists believe that they are two different characteristics, although they do not rule out that they may be related in some way. Since the young stars studied (giants and Cepheids) were born from galactic gas, the team suspects that the wave not only carries the stars, but also the gas itself from the disk. The stars would have simply inherited the motion of the gas from which they formed, preserving a “memory” of the wave. Now the investigation must continue. Astronomers are looking forward to Gaia’s fourth data release, which will provide even more precise measurements and help create detailed maps to perhaps finally reveal the origin of our galaxy’s undulating heart.

Openai has just presented Sora 2 with own Tiktok -style app. This is outlined a new wave of viral videos

by

You open the mobile and, in a few seconds, you see yourself inside a scene that did not exist a minute ago: you are the protagonist of a clip that seems really shot, with movements and rebounds that feel coherent. Mechanics has no mystery, you record a brief take to capture your voice and face, and the app “place” on stage. The striking thing is the feeling of control, you can chain planes and maintain the state of the world without anything falling. There begins the game of Sora 2. To understand what Sora 2 supposes to look back. The road opened in 2022, when Chatgpt He placed the generation of text at the center of the technological debate. That impulse gave way to image models and, in February 2024, to Sora’s first versiona prototype that already showed permanence of objects and some visual coherence. The competition soon react: Runway with his Gen-4 and other projects marked the pattern of a market in full boiling that now receives a new chapter. What’s new in Sora 2. Openai describes this model as a jump comparable to that in its day GPT-3.5 was for the text. The big difference is in physical loyalty: if a ball fails the hoop, bounces on the board instead of teleporting, a common error in previous systems. You can also maintain the status of a scene between plans and follow more complex instructions. In addition to video, it generates voices, effects and sound landscapes, which makes it a much more complete video-audio tool. The app: Cameos, Remix and Feed. Together with the model An application arrives Designed to use it social code. After a rapid face and voice verification, the user can be inserted as cameo in any scene and share the result with their contacts. The app allows you to remix videos of others and navigate a Feed which adjusts to preferences through natural language. Openai ensures that the experience is designed to encourage joint creation, not passive consumption, and that it opens under invitation in iOS. Welfare and security: controls and limits. The company led by Sam Altman He insists that his application does not seek to catch the user in an infinite scroll. It is designed to prioritize known people and encourage creation more than consumption. Base restrictions are applied for adolescents, as a limited number of generations and stricter permits in cameos. To this are added parental controls from chatgpt and the possibility of revoking any use of your image. There will also be human moderators for cases of harassment. Is it free? As we say, the application of Sora 2 gradually opens in iOS, with an initial deployment in the United States and Canada. Openai promises to extend it to more countries, although for now it is not available in Spain. Access requires invitation and can also be requested from the Sora.com website. The service starts free of charge, with use limits that depend on “the computing capacity.” In addition, the subscribers of Chatgpt Pro, the 200 dollars per monthThey have access to a Sora 2 version with higher quality, and the company plans to enable the model via API. Some failures remain. Among the spread examples appear anime fighting, explorers that shout under a snowbird or acrobatics that respect rigidity and flotation. The model manages to give the impression that the failures belong to the character himself, not to the algorithm. It also allows you to insert a real person into a scene with recognizable voice and appearance. Even so, Openai admits that errors abound and that general coherence is far from perfect, although it considers that the progress with respect to Sora 1 is evident. Sora 2 raises a scenario in which videos cease to be just a consumer product and become a shared game space. The key is in that ability to turn anyone into the protagonist of a clip ready to circulate. It may be a fashion of short duration or inaugurate a more participatory creativity stage. What seems clear is that Openai has returned to place the focus on the daily user, with a proposal designed to trigger waves of viral content.

Before the great fire wave in Spain, science already has a culprit of its propagation: climate change

by

This 2025 It has been a devastating year for Spain and Portugal Because of the A large amount of forest fires that they have been giving, In many cases intentionallybut that were fueled without control. A new scientific analysis has concluded that the climatic crisis has played a determining role, multiplying by 40 the probability that the extreme weather conditions that fueled the flames would be given. Not just that. The study determines that these phenomena were 30% more intense than they would have been in a world without global warming. And this is important to highlight it: the study does not indicate that climate change causes fires, but they intensify their force of destruction when they make them uncontrollable more likely. Putting figures. The reportprepared by the World Weather Attribution network, put figures to a catastrophe of historical dimensions. On September 1, the fires had calcined about 380,000 hectares in Spain and 260,000 in Portugal. In total, 640,000 hectares, an area four times higher than that of London and represents approximately 1% of the surface of the Iberian Peninsula. In historical terms, for Spain 2025 it will close as the fifth year with the highest burned surface since there are records in 1961. If we are going to European, we can affirm that the worst year since The EFFIS system (European Forest Fire Information System) began registering data in 2006, with more than one million hectares calcined, being two thirds of those corresponding to Spain and Portugal. Impresses researchers. “The size of these fires has been amazing”, affirms Clair Barnes, scientist at Imperial College in London and co -author of the study. “Warmer, dry and flammable conditions are becoming more severe with climate change and are giving rise to fires of an unprecedented intensity.” And it is that the surprise is logical. According to the data they have analyzed, they point out that these extreme risk conditions for the propagation of fire will be given every 15 years with the current climate. This is something that only happened once every 500 years in the preindustrial era. An explosive cocktail. The fuel of these megaincendios was an unprecedented weather situation. The large amount of fires occurred during a heat wave in Spain that was one of the longest ever registered, with a duration of 16 days (from August 3 to 18). But it was not only the longest, but also the most intense, with an upper 4.6 ° C temperature anomaly compared to a pre -industrial climate. The impact of climate change in this extreme heat is even more pronounced. According to the analysis, a ten -day heat wave as intense as the lived is now an event that is expected once every 13 years. Before humans began to heat our environment, such a heat was extremely rare and it was only expected to happen less than once every 2,500 years. It is not just the weather. Although the report points to climate change as the great amplifier, it is not the only factor. Scientists highlight that both in Spain and Portugal, rural depopulation and population aging have left large extensions of forest land without managing, creating a massive accumulation of dry vegetation that acts as a perfect fuel. One of the examples that is put is in the decrease of traditional practices such as extensive grazing has reduced natural control over that vegetation. David García, applied mathematician of the University of Alicante and co -author of the study, points out that the public debate in Spain has focused a lot on the decline of these rural activities. It points to that “much less the effect of climate change has been discussed in these fires, which, as has been demonstrated, has been immense.” To this is added that human ignition, whether accidental or intention, is behind about 90% of fires whose causes are identified. With huge fuel loads and extreme weather conditions, minor human actions can trigger catastrophic results. The science behind. To reach these conclusions, the research team analyzed the weather conditions that the fires propitiate using the daily severity index (DSR), which is a metric derived from the Canada Fire Meteorological Index (FWI). In summary, this index combines long -term rainfall data, temperature, humidity and wind to estimate the probability and severity of a fire. In this way, the scientists compared the meteorological data observed in the current climate (which has been heated from the pre -industrial era) with a counterfactual of how these conditions would be in a climate without that warming. In this way, with the methodology used, the “footprint” of climate change in a specific extreme event can be isolated and quantified. The result. The climatic crisis is taking the ecosystems and response capacity to the limit. For the first time, Spain activated the EU Civil Protection mechanism to request help in the fight against forest fires, and now they are already raised to apply new regulations with the aim of preparing for the future that awaits our country.

Aemet has already concluded the heat wave. Now experts look at Hurricane Erin to know if the cold will endure

by

After a heat wave long and intenseSpain begins to travel a few days of thermal relief. However, after several warm episodes, it is worth asking whether the stabilization of temperatures will last over time or if on the contrary the heat will return. Days of calm ahead. Everything seems to indicate that we have several days in which temperatures will remain within normality. We will even see several days in which these will be something below the usual for these summer dates, According to the forecasts of the State Meteorology Agency (Aemet). So much so that even the rebound of temperatures that are expected towards the end of this week and beginnings of the next will not lead us to a particularly warm situation. The cold thermal anomalies At some points they could be below the nine degrees in some areas of the peninsular center, according to expert predictions. Gone is therefore the last heat wave, an episode that has not only been intense but also Looking at the western Atlantic. At the beginning of the week we pointed out that experts looked closely at what happened these days in places as far from our territory as the Western Atlantic and the Antilles archipelago. The reason was in the tropical storm Erin, a storm that reached the category of hurricane and whose journey seemed to turn to the north first and northeast later, undertaking a direction that would take her from the tropical waters to middle latitudes. Why interest? The key is on the impact that this storm could have on atmospheric circulation in these latitudes. According to explained a few days ago The physicist, disseminator and researcher at Aemet, German JJ, the emergence of this cyclone into medium latitudes could complicate the average weather prediction in Europe. Erin regroups. Erin seems to follow the established script and is already in the north direction. The storm has restructured in the last hours, so it can be expected that its progress will continue during the next few days. According to the National Hurricane Center (NHC) of the United States, the hurricane is off the coast of Florida. If the forecasts are completed, the storm will run in parallel to the east coast of the US during the next few days and between Friday and Saturday will reach the 40th parallel, already standing in our latitude. This, details German In another publicationimplies an important change in both atmospheric circulation and in the Jet Stream On the Atlantic, which will strengthen the cooling effect we are now seeing. “Thanks to this, atmospheric dynamics in our region will give a radical change, seem more like that of autumn,” he says. Uncertainty. We will have to wait to learn more about Erin’s course and its impacts, direct or indirect, about Europe. This hurricane reached category 5, becoming the first significant hurricane in a relatively meek season in Atlantic waters. The good news is that, if we can reach our environment, it will already do so as a subtropical storm or post-tropical cyclone, probably entering the continent to higher latitudes than ours.

We believed that the heat wave was over. Aemet warns that, in reality, we still have the worst ahead

by

The heat wave that affects the peninsula is leaving shocking data. Yesterday, three of the weather stations of the State Meteorology Agency (AEMET) collected maximums above the 45º Celsius, with 55 registering more than 42º. Two records of record. On August 11 and 12 they beat, According to Aemettwo temperature records. With an average temperature that touched the 29th in peninsular Spain, this month has seen on August 11 and 12 more than at least 1950. In fact, they are among the warmer days registered in August: only three times the 29th Celsius barrier has been overcome. On August 12, it was also the hottest day than is going 2025. If they are fulfilled The agency’s forecaststhe first twenty of August will be the warmest in peninsular Spain since there are records, exceeding a few tenths the previous registry (of 2003), and for more than one degree the next highest record, last year. From Seville to Badajoz. Yes Let’s go to the most extreme caseswe can find the 45.2º of the weather stations of Seville, Tablada and El Granado (in Huelva), or the 45.5º collected in Badajoz. Another striking fact were the high minimum temperatures: 29.7º in Osuna (Seville), the highest in peninsular Spain (in Gran Canaria there were thermometers that did not fall from the 30). A number that does not want to leave. The answer to the question of “what is happening” has to do with atmospheric stagnation a “synoptic configuration continues quite stationary”, In Aemet’s words. A dorsal anchored on the peninsula That allows the entry of warm and dry air from Africa, as well as the high degree of insolation propitiated by summer and stable skies, are main responsible for a heat wave that is not only being intense, also long. The latest update of Aemet’s forecasts indicate that this exceptional situation will last at least until Monday 18. The “more likely” scenario is that the entrance of a fresh air mass from the Atlantic serves to relieve the situation, but there are still a few days left for us to know greater certainty when and how the end of this heat wave will be given. What can we expect. Meanwhile, what can we expect? After a kind of brief respite today, Aemet foresees A new increase in temperatures tomorrow Thursday, a more marked ascent in Galicia, where the thermometers can exceed 38º. On Friday this ascent will be extended throughout the north, where orange notices are already planned due to an important risk derived from high temperatures.

After weeks of concern, the Mediterranean is very close to normal. The heat wave threatens to throw everything into the fret

by

Something has changed sharply in the Mediterranean Sea: its temperature. If a few weeks ago the sea that unites Europe, Africa and Asia burning, now the surface temperature of the sea has plummeted to almost normal values, only slightly above what we could expect during these summer dates A few tenth. The latest data on the surface temperature in the Mediterranean Sea have given us good news in the form of stabilization. According to the data Of the coastal observation and prediction system of the Balearic Islands (Socib), as of August 7, the Mediterranean surface is, on average, at 26.03º Celsius. This implies an anomaly was 0.54º Celsius, that is, the sea is more than half a hot than what would correspond at this time. As a contrast, in the middle of June We reported that this anomaly was 2.26º. East to the west. The sea temperature has decreased on average, but has also changed in its distribution. A few weeks ago the focus of the heat was in the Western Mediterranean, while to the east the temperatures were warm but more moderate. Now it happens just the other way around. According to the Socib datathe average west temperature of the Mediterranean is 25.01º, which implies a thermal anomaly of 0.29º. Meanwhile, the eastern side is at 27.06º, 0.81º more than what would be normal in that area and on these dates. A very diverse sea. The data allow us to analyze the change in different regions and, perhaps the area where this change is most palpable, the Northwest Mediterranean. Here, at the beginning of July the thermal anomaly was around four degrees. Now is the most “normal” area of the sea, with a positive anomaly of only 0.17º. Another of the spotlights a few weeks ago was in the surroundings of the Balearic Islands, especially in the waters of the National Park of the Cabrera Archipelago. In these areas, thermal anomaly on June 12 was 3rd and 3.18º respectively. Now, the environment of the Balearic archipelago is only 0.36º above the average, while the waters of the Cabrera archipelago have an anomaly of 0.35º. What happened? June was an extremely warm month in Spain, but it was also hotter than normal in other areas. The absence of section of section and high insolation made the Mediterranean a boiling pot, but the month of July was different. The arrival of a time less torrid in a month of July in which the storms took the prominence in the Mediterranean basin changed this. “Thanks to the dynamics of atmospheric circulation in recent weeks, with the passage of different troughs, the surface waters of the Mediterranean already draw a panorama with a more normal spatial variability,” explained on social networks The physicist, disseminator and researcher at Aemet JJ German. Without throwing the bells on the flight. The descent of temperatures is great news: a Mediterranean too warm increases the risk of storms and copious rainfall like the ones we see in Danas and in episodes of “cold drop”. The question now is to know if this stabilization will be lasting or if we will see a new thermal rebound in marine waters. August has started with a heat wave in Spain with reach beyond the peninsula. June’s thermal rest has ended and we do not know how this change to the waters of the Mediterranean will affect. The issue is relevant due to the environmental and meteorological problems that this overheating would imply.

This heat wave has very little normal because of a “stationary” situation

by

We approach the culminating point of the heat wave. In many places the thermometers have already exceeded the mark of the 40º Celsius and the situation will last throughout the week, according to the forecasts. The question for many is to what extent this is strange in the middle of August. In full heat wave. Yesterday we lived that could be the first day of the new heat wave that looms over Spain. During the day the State Meteorology Agency (AEMET) registered temperatures above 43º In two seasons in the south of the Peninsula (Badajoz, and Almadén, in Ciudad Real), but many more registered maxims above 40º. A heat, normal? The last days of July and early August tend to be the hottest of the year. That is why it is logical to think that we are simply at the heat of the cannula. However, there are ways to verify that this is not the case. First, the terminology used: heat waves are, by definition, abnormal heat situations. Although there is no strict definition of what a heat wave is, we can resort to Aemet as standard. This situation occurs when at least 10% of the weather stations collect temperatures in the 95th of the distribution for at least three consecutive days. The agency has warned of the possibility that we are in the first days of a heat wave, it has not confirmed that we are already in one since we are still talking about forecasts. Of course, the probability assigned to the event is high, of 80%. More than 10. Another way of seeing the uniqueness of this event is through thermal anomalies, the difference between the temperatures that we predict or observed and the average temperature that would correspond to these dates in a certain place or area. According to Physicist Sergio Escama points out in Meteoredthe weather models advance thermal anomalies between 10º and 12º that will affect “wide areas” not only of the southern peninsular, also the center and interior. The heat will also be elevated for dates in the northern half, although foreseeably not until the same point. The answer, also in the atmosphere. If we want to understand what has normal and what is anomalous this situation, we can also look at the situation of the atmosphere. According to Details Aemetwe are faced with a “quite stationary, with high Atlantic pressures extending over a large part of the territory and low pressures to the peninsular southwest”. This situation facilitates the entry of warm and dry air from North Africa. The situation is aggravated by the fact that we are in summer, which implies a high degree of insolation due to the longest days and the greatest angle with which the sun affects the territory. What can we expect from the heat wave. The agency foresee That the maxims today continue to rise, with the mercury exceeding the 40º “in large areas of the southern half of the Atlantic aspect and surroundings of the Miño,” according to the agency in its forecast. Tomorrow Tuesday could also register temperatures above 40º in much of the southern half of the Atlantic aspect and also in the depressions of the Northeast. Thus, Aemet He has activated notices For extreme temperatures in almost the entire peninsula, with several orange notices for important risks in part of the southern quadrant, Andalusia and areas of Galicia. Many of these notices will remain active during the highest heat hours at least between today and Thursday. The northern hemisphere, to the red red. The anomalous situation that affects our environment has its reflection in the data at a global scale: the northern hemisphere is also in a situation of warm anomaly. According to the data of Climate Resanalyzer (of July 29), the average temperature in this hemisphere is 22.43º. This represents a thermal anomaly of 0.75º with respect to the average of the years between 1991 and 2020, but an anomaly of 1.14º above the average of the years between 1979 and 2000. This implies that we are before the third most warm August in the northern hemisphere, behind the year 2023 and tied with 2024.

habits and tricks to sleep under an extreme heat wave

by

During a heat wave it is common for us to put our focus on the scorching maximum temperatures. However, this is not the only indicator that warns us of the problems that we must face during this type of episodes, minimum temperatures can be so important or even more in some circumstances. The “tropical nights.” According to it The State Meteorology Agency (Aemet) before the start of this heat wave, one of its characteristics would be that of the Tropical nights. This term refers to those nights in which the minimum temperatures do not fall from the 20th Celsius. The forecasts They talkedin fact, of minimum temperatures that could exceed 25º, nights to which a different term is applied, that of “Equatorial nights”. Already before the entry into force of the agency’s special notice on the occasion of the heat wave, some areas of the South such as Seville or Almería (but also in other areas such as Girona) They registered minimal Above this 25º barrier. Why is it so difficult to sleep? There is a close relationship between body temperature and sleep cycles. The hours of sleep our body temperature is usually faster than during the day, but the descent in body heat usually starts before we sleep. Even before we lie. The problem arises with the arrival of excess heat. Some scientists theorize that with heat It can happen as with lightwhich would be used as a reference by our body to distinguish the night of the day, the hours to dedicate to the dream of vigil. If it is hot, or if there is light, our body interpretter that is not yet time to go to sleep. The tools in our hand. The simplest option is to plug a fan or keep the air conditioning on all night but this is not always an option, either because we do not have any of these devices, to avoid scares when paying the electrical invoice or, even, because they are not options too convenient for our health. So what can we do? If heat is like the light that prevents us from reconciling sleep, a simple strategy is to isolate ourselves from it as we isolate ourselves with light. We can start by choosing an isolated room, away from the facades, oriented to the north and not to the south, or far from the upper plants if we live in a house with more than one plant. To maintain this fresh room, it is convenient to ventilate it, but not expose it to the entry of light, also avoiding artificial light sources and heat sources such as burning or mobile computers loading. Cool Maintaining a fresh sleeping environment is important, but maintaining our own fresh body is too. The strategies that we would conventionally use to refresh ourselves, even those that are contraintuitive, can be of great help. Avoid what can increase our body temperature during the afternoon, such as especially hot meals or physical exercise can also be useful. “Sleep hygiene.” Sleeping during a heat wave is especially difficult but sleeping strategies better that we use conventionally can also help us. In this sense, correct sleep hygiene can be helpful in these cases as in others. Habits such as maintaining regular schedules, or avoiding screens and lights before bed are usually among the usual recommendations in this regard. An active life and healthy eating can also help us fall asleep better, even in conditions like these. The heat wave ends, but … The forecasts indicate that temperatures will fall during the next few days, being able to conclude the episode the day after tomorrow. However, we are only at the beginning of summer, a summer that has started intense but whose evolution is for now uncertain. The tropical nights have been accompanying us for weeks and probably keep doing it during the summer. These can be aggravated by situations such as the current one, but in themselves they are not a rare phenomenon in the summer (although it is likely to become more and more frequent). Adapting to them is therefore important if we do not want to sacrifice our rest for several months a year.

Meteorologists are dismayed at the heat wave of Africa and Asia

by

“We are witnessing something incredible. By far the most extreme climate phenomenon in world history. Thousands of records are beating brutally from North Africa to Asia. And with margins never seen.” These words They are from Max Herradorone of the greatest public experts in extreme meteorological phenomena. And seeing Maps like the one that opens this articleI don’t lack reason. The best example is Kuwait. According to provisional data, the Kuwaiti city of Mitribah exceeded 46 degrees in April For the first time in history. And, just after, he exceeded 47, then 48 and, finally, he put almost 49. It is not an isolated fact: More than 45 degrees in Egypt, in India or in the Middle East; 45 also in Sudan, 45.7 in Chad, 45.5 in Niger; Central Asia records completely sprayed. We talk about absurdly high temperatures for latitude 30 at this point of the year. In the case of Mitribah they are very close figures to the historical maximum reached. In addition, the heat wave has a huge extension that covers three continents. And, as Herrera points out, everything indicates that the situation It will get worse. Tropical tidbits What is happening? It is a great question. Because heat waves They never come alone. They have serious social implications (more aggressions, more violence, more crimes, more Homicides) In areas of the world that right now are a polvorín: Syria, Israel, Ukraine, Sudan … The problem is that we don’t know very well why all this is happening. A priori, we can think that the same atmospheric dynamics that it has given us an extraordinarily wet March and a much cooler spring of what is usual is the one behind the heat waves of much of Central Europe, Africa, the Middle East and Asia. After all, in meteorology the masses of air are pieces that play a strategic dance between them and the changes that occur in any part of the world, have effects on the rest. An increasingly uncertain future. I do not know if Herrera is right and we are living one of the most extreme meteorological phenomena in the documented history of the earth. However, it is clear that the situation only complicated. Not only because things are changing very fast, but because we don’t know where it goes.
