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 [...]
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 [...]
COP 30 will be held in 2025 in Belém, Brazil, from November 10 to 21. Three decades have passed since COP 1 in Berlin, 1995, until COP 30. This period marks an important milestone in our planet's climate. Thirty is a round number, ideal for taking stock of the achievements and failures of the COPs [...]
The National Oceanic and Atmospheric Administration (NOAA) reported that 2024 was the warmest year on record. Current projections predict that 2025 will be even warmer. Among the consequences of the unstoppable rise in temperature are extreme heat and cold waves, devastating floods, massive forest fires, droughts, hurricanes, tornadoes, and other catastrophic events. What are we [...]
Every year, March 22nd is World Water Day. This year's theme is the title at the top of this article. These three simple words, “save our glaciers”, already indicate the relationship between glaciers and freshwater. What is a glacier? Glaciers are large masses of ice and snow formed on the Earth's surface by the accumulation, [...]
For this year, 2025, the United Nations has decided to celebrate the International Day of Forests with the theme “Forests and Foods”, to recognize the fundamental importance of all types of forests for their impact on “food security, nutrition, and livelihoods”. The goal is to raise awareness about the importance of forests for the planet, [...]
