We have been observing the snow of the northern hemisphere from space for 40 years. The conclusions of the latest major study are devastating

As some older people around us say: winter is already it’s not what it was. As we move forward in the decade, scientific data paints an increasingly clear and disturbing picture of the amount of snow that has accumulated in some parts of our planet. And the images seem to leave no room for doubt, since they suggest that snow coverage in the northern hemisphere is constantly reducing, altering the seasonal cycles that govern our climate. The data. The last job we have had access to was published in January of this same year, and the conclusion they have drawn is quite devastating when pointing out that 24% of the regions of the northern hemisphere show a significant decline in the presence of snow, compared to a mere 9% that has registered an increase in its amount. How it looked. To reach these conclusions, researchers have not limited themselves to looking at the thermometer. They have turned to a gigantic high-resolution database that brings together historical data since 1980 with information on both snow and ice. Mathematical model. But the real advance in this case lies in the use of advanced statistics. And, expanding on previous research from 2023, they have applied a two-state Markov chain model, which in simple terms is a mathematical model that allows analyzing the spatial and temporal probabilities of snow persisting or disappearing in specific grids on Earth over decades. That is why we are facing one of the most rigorous methodologies that currently exist to understand snow trends, eliminating the “noise” of the precipitation that is coming in the coming months. Early spring. But… Where exactly is the snow disappearing? The Markov model reveals that the decline is not uniform, but there is an alarming pattern that directly affects our side of the globe: spring melt is coming forward dramatically in Europe and Central Asia. Right now we are seeing snow melting earlier, shortening winter temperatures and directly altering the water cycle, which is vital for agriculture and ecosystems during the warmer months. The consequences. But it is not something new, since previous works already warned of this loss of snow, which is a decline that not only affects water reserves, but also the ability of the Earth’s surface to reflect solar radiation. Something that is not nonsense, since less snow means more exposed dark land, greater heat absorption and, consequently, an increase in regional temperatures. A consensus. In addition to this study, in 2025, research was also published that analyzed possible biases in climate records. NOAA historicalconfirming that the decline in snow during autumn and winter is a real phenomenon and not an erroneous measurement. But it does not stop there, since the last Arctic bulletin painted a very extreme scenario, since, although there was above-average snowfall until May 2025, the decline during June was so rapid and abrupt that snow coverage was reduced to half of what it was 60 years ago. A mixed and volatile pattern that shows a climate system under stress.

The most powerful telescope in Europe has seen something rare while observing two brown dwarfs: a perpendicular planet

Today, in things that we did not know that there were in other star systems: a planet that orbits perpendicular to its two stars. It is as strange as it sounds. A different planet. We have seen everything in the exotic exoplanet gallery that the observable universe offers us, but a new surprise has forced astronomers to readjust their expectations. Using the Vary Large Telescope del Southern European Observatory (ESO) In Chile, astronomers have found the first exoplanet known in a polar orbit around a binary system of stars: two young brown dwarfs. Orbiting at 90 degrees. Baptized as 2m1510 (AB) B, this world has two Tatooine style soles, something extremely common when it comes to more massive stars, but not so much in the case of brown dwarfs. However, what is common is that orbits its two host stars in a way that until now had only theorized: turning perpendicular to them, in a polar orbit of 90 degrees. We sensed that they could exist. Astronomers had already detected planetary training discs in polar orbite and theory suggested that They could form stable planetsBut finding them was another story. 2M1510 (AB) B is the first credible test that this configuration exists. And the most curious thing is that the team was not actively looking for this type of planet, they found it while refining the orbital and physical parameters of the two brown dwarfs, seeing that the path of the two stars was being pushed and pull in unusual ways. It is not a usual system. The planet is not the only rare in this neighborhood, taking into account the host stars. Brown dwarfs are larger than giant giant planets, but too small to maintain nuclear fusion which characterizes the stars “really”. But the rarity does not end there. These brown dwarfs form an eclipsest binary, which means that from Earth we can see how they hide each other. 2M1510 (AB) is an incredibly infrequent system: the second pair of eclipsessing brown dwarfs known to date. With more than 5,800 exoplanets confirmed to date, only about 16 orbit around two stars. That one of them does precisely around a system as atypical as a binary of eclipsessing brown dwarfs, and with a polar orbit, it is a real cosmic jewel.

Sweden did not believe Russia’s economic data. He has found the proof he was looking for by observing Moscow from space

If the question is how Russia’s economy is doing, the answer surely depends on who you ask. A few weeks ago, The New York Times published a report where he explained the tensions that exist between the Russian elites as economic growth slows of the nation. They signed up the sanctions and the war itself, but in the face of rhetoric, Moscow responded that they would endure all threats. Sweden was not so clear, and claims to have evidence of the real situation. Stagnation and signs of slowdown. As we have told other timesthe war economy that Russia launched at full speed after the invasion of Ukraine appears to be showing signs of significant slowdown. In fact and as the Times emphasizedeven generating tensions among the country’s economic elite as the conflict enters its fourth year. According to recent official data, many civil sectors have stopped growing and have even begun to declinewhich has exacerbated economic uncertainty. The Russian currency, the ruble, fell three weeks ago to its lowest level in two yearsand companies face difficulties in obtaining new loans or receiving payments from customers, reflecting an increasingly restrictive financial environment. Rise in interest rates. The response of the Central Bank of Russia has been a drastic rise in reference interest rates, reaching 21% in October, the highest level since the fall of the Soviet Union. Despite efforts to contain inflation, the economic growth forecast for the new year has been revised downwards, standing between 0.5% and 1.5%well below the 3.5% to 4% recorded in 2024. In the background, the elephant in the room: the slowdown occurs despite the continued record government spending to finance the warwhich indicates that economic stimuli are no longer having the same effect. Economists and officials have begun to warn about the imminent risk of so-called stagflationa dangerous combination of price increase without economic growth. The impact of sanctions and the Russian response. The strict economic sanctions imposed by the West in response to the invasion of Ukraine have limited Russia’s ability to maintain its military-spending-fueled growth. In this regard, the Kremlin has insisted that it has withstood the impact of sanctions, but slowing growth and rising inflation indicate otherwise. Civilian businesses, in particular, have been hardest hit by the economic crisis. For example, Russian Railways, the country’s largest employer, reported a 9% drop in cargo volume transported last October compared to the previous year. To counteract this decline, the company has announced a price increase of more than 10% and has reduced its investment plans for 2025 by a third. Despite this, experts consider that the crisis is not yet serious enough enough to force President Vladimir Putin to reconsider his ambitions in Ukraine. Conflict Central Bank and the industrial elite. One of the main points of conflict within the Russian economic elite is the relationship between the Central Bank of Russia and the country’s leading industrialists. The bank’s governor, Elvira Nabiullina, has implemented a strict monetary policy to curb inflation, which has generated criticism from businessmenwho argue that record-high interest rates are stifling growth. In response to these, Nabiullina recently defended his strategy before Parliament, arguing that all the country’s economic resources are being used to the maximum and that macroeconomic stability should not be sacrificed for accelerated growth. However, its position has become increasingly isolated in an environment in which Business interests demand more flexible measures to sustain their operations in a context of growing uncertainty. Distrust in official figures. And in the face of domestic rhetoric, Western officials have expressed skepticism about the veracity of the economic data provided by the Kremlin, arguing that the official figures do not accurately reflect the reality of the Russian economy. In this regard, the Minister of Finance of Sweden, Elisabeth Svantesson, expressed during the World Economic Forum in Davos that Russia is presenting an image of economic stability that does not match the real situation. According to Svantesson, government statistics, which put inflation at 9.5%are not credible considering that the Central Bank of Russia has raised interest rates to 21%a discrepancy that suggests much greater inflationary pressure than is officially recognized. Furthermore, the continued flight of capital is another indicator of the country’s economic difficulties, which a priori contradicts the Kremlin’s narrative of resistance to Western sanctions. The “trick” of space. Thus, and given the lack of confidence in Russian data, Western officials have resorted to alternative methods to assess the nation’s economic health, including in the equation analysis of night satellite images of Moscow. Svantesson pointed out that city ​​lighting in 2023 was visibly dimmer compared to 2021which, in his opinion, suggests lower energy consumption and, therefore, a decline in economic activity. In fact, comparative photographs from media like Business Insider showed that, although factors such as cloud cover and time of day can influence perception, in general a pronounced decrease in illuminated areas is observed, especially in the suburbs of the capital, which could point to this deterioration in the level of life and possible cuts in the electricity supply. Manipulation of the economic narrative. Svantesson went a little further, and even emphasized that the Russian government’s official narrative seeks to convince Ukraine and its allies that sanctions have not had the desired impact. However, the data (and alternative data, such as the analysis of night lights), suggest that the economic reality is somewhat different from the image projected by Moscow. The minister concluded that, although the exact state of the Russian economy cannot be known with certainty, what is clear is that “the official version promoted by the Kremlin is not true.” Image | POT In Xataka | The end of the war is very far away for two reasons.
