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 [...]
The polar vortex is a phenomenon that normally occurs in the upper atmosphere above the Arctic. It manifests as a mass of cold air that rotates counterclockwise, growing and shrinking with the changing seasons. The phenomenon was diagnosed as a “sudden stratospheric warming”, which caused the vortex to disperse and reverse its circulation, lowering temperatures [...]
On the occasion of the celebration of World Water Day and 2025 being the “International Year for the Preservation of Glaciers”, the United Nations Assembly (UN) agreed to designate March 21 as World Glacier Day starting in 2025. The United Nations sets the objective for celebrating World Glacier Day: Raise global awareness of the critical [...]
Every year, on April 22, International Mother Earth Day is celebrated. A motto is chosen for the occasion. For this year 2023, has been chosen: “Invest in our planet”. It is a message to work for a green and sustainable planet that offers the opportunity to live on a healthy planet, through a green economy [...]
The First Earth Summit turns half a century old in June 2022. In this article we analyze the positive and negative events that resulted from Stockholm-1972 in these 50 years. The Conference produced the "Stockholm Declaration", which consists of two bodies of articles that contain seven Proclamations and 26 Principles aimed at normalizing the relations [...]
