America’s 250th birthday is not looking very celebratory. Hot temperatures from the United States to Europe are reaching their highest levels since previous years. From the last week of June, meteorologists have spotted multiple signs of the heatwave phenomenon, El Niño, making a return. People are taking precautions to stay hydrated and take shelter under shaded areas as the immense heat reaches ‘Super’.
How Does El Niño Occur?
El Niño occurs when the Earth’s trade winds are weakened in the Pacific. In normal conditions, cold and hot trade winds are necessary to regulate ocean temperatures in a process called upwelling. These winds travel between South America and Asia.
Since the 1600s, unnatural heating has occurred in South America, peaking its conditions around December. Areas across the Northern US and Canada experienced drier climates, while Southern US and South America suffer from high humidity, increasing the chances of hurricanes, tropical storms, and flooding.
According to the National Oceanic and Atmospheric Association, El Niño happens every two to seven years. The last time the Little Boy of December overheated the world was between 2023 and 2024.
Measuring Super El Niño’s Strength
So what makes Super El Niño more dangerous? Meteorologists have observed and traced indicators of its development since Spring 2026. The International Research Institute’s Climate and Society department monitored the Pacific using the Niño 3.4 Index to trace the weather phenomenon and its colder sibling, La Niña.
At first, its heat levels were detected at neutral oscillation, then rapidly rose to El Niño status. The forecast at the time was a 70% chance of strengthening during the April-June period. The IRI reported a high probability of its dominance from 88% to 94%.
From May to June, marine scientists observed and recorded seabird deaths to detect the dangers of the ongoing heatwave. Marine ornithologist Tammy Russell informed the Associated Press that various species are desperately seeking food in odd places, such as fishing boats and piers. Flocks will undergo starvation due to high ocean temperatures in areas where krill, anchovies, and sardines reproduce.
Russell finds the immense heat disturbing as she and other scientists witness the seabirds’ death occurring in minutes. “We’ve been seeing cormorants walk to shore and then just die within the hour. I mean, one time it happened within 15 minutes, and I’ve never seen that before,” she told the Associated Press. “That has been heartbreaking for me, and we’re seeing this happening across the whole [California] coast.”
The recent weather conditions have confirmed that the oceans were simmering on Jun. 21. The Copernicus Climate Change Service (CCCS) explained to Euractiv measured about 69.7°F (~21°C) outside of the polar regions, which mirrors the 2023-2024 El Niño season. They raised natural disaster precautions across Europe as it spread to South America, Africa, and Australia.
Local Texas network, KTAL, is watching the ArkLaTex region as multiple areas surpassed 100°F. Meteorologists are expecting to see a repeat performance from 2015 of the upcoming autumn and winter months. ArkLaTex survived through a series of tornadoes, heavy rainfall, and flooding. Residents of Kerr County, who suffered from Tropical Depression Chantel in 2025, are still carrying the weight from last year’s disaster after DOGE disbanded the NWS before the storm.
And Super El Niño’s effect continues to spread chaos. Across the United States, the heatwave is reaching new levels of natural disasters. Colorado is under a firewatch after the Aspen Acres were set ablaze, breaking a new record of burning over 85,500 acres. Fourth of July celebrations are canceled in Chicago as the suburbs experienced flooding.
And finally, ABC reported that over 842,000 homes are without power, giving them no access to air conditioning to stay cool in 100°F. Families and individuals are resorting to cooling centers as they partake in the holiday ceremony. Despite the Trump administration and Environmental Protection Agency Administrator Lee Zeldin want the population not to worry about global warming, the signs show that it is no longer an option.
