What are atmospheric rivers and how do they work? The term "atmospheric river" (AR) has appeared in scientific records since the 1990s. The American Meteorological Society (AMS) added it to its meteorology glossary in 2017. Atmospheric river: A long, narrow, and transient corridor of intense horizontal water vapor transport, typically associated with a low-level jet [...]
In 2026, ocean surface temperatures surpassed global historical records, reaching unprecedented levels, according to scientists. This extreme warming directly alters marine ecosystems and intensifies weather phenomena worldwide. Below, we analyze the causes, impacts, and projections associated with this climate milestone. Unprecedented ocean temperature record in 2026 According to the Copernicus Climate Change Service, the planet's [...]
Before we learn about the Super El Niño 2026, what do we call the El Niño phenomenon? El Niño is the warm phase of a natural climate cycle known as the El Niño-Southern Oscillation (ENSO). It is characterized by the anomalous warming of surface waters in the tropical Pacific, which alters atmospheric circulation and modifies [...]
La Niña phenomenon and Earth's climate system Below, we explore the scientific origins of this anomaly and its global impacts on rainfall patterns—with a particular focus on hurricanes—and examine the urgent adaptation strategies societies must adopt in the face of climate change that is rapidly transforming the globe. The scientific community is currently monitoring the [...]
The El Niño phenomenon in 2026 is already a reality. The planet faces some of the harshest climate conditions in recent decades. Forecasts predict record ocean temperatures and atmospheric disruptions, creating a landscape divided between devastating droughts in some regions and catastrophic rainfall in others. Below, we analyze the scope of this climate threat [...]
Peru is closely linked to the El Niño phenomenon. In this South American country, the northern coast is the geographic focal point for anomalous ocean warming, which directly alters the Humboldt Current ecosystem and the region's climate. Fishermen as Key Figures The connection is so strong that fishermen from northern Peru named the El Niño [...]
The first major global climate catastrophe The Super El Niño phenomenon of 1877-1878 is the most intense documented so far. This phenomenon contributed to widespread drought and famine in several countries, causing the deaths of more than 50 million people. These are the three countries that suffered the most from the Super El Niño The [...]
How many PPM and °C increases will the war cause by the end of 2026? IIn these days of crisis, we are seeing images of enormous oil and natural gas extraction and storage fields ablaze, spewing thick plumes of black smoke into the atmosphere. We have also seen countless tankers burning, their millions of barrels [...]
The polar vortex is a phenomenon that normally occurs in the upper atmosphere, above the Arctic or North Pole, characterized by a large mass of cold air that rotates counterclockwise, growing and shrinking as the boreal winter progresses. In 1985, an extraordinarily cold event occurred in North America, linked to the polar vortex, that lasted [...]
As we write this, two months have passed since the close of COP30, held in Belém, Brazil, between November 10 and 21, 2025, a meeting that had generated much hope, but whose final outcome fell far short of expectations. When a COP ends, usually set on a Friday, all environmentalists rush to draft their summaries [...]
