The National Aeronautics and Space Administration (POTfor its acronym in English), reported that the average temperatures of the last 12 months have been the highest recorded in modern times. Among the reasons, long-term warming driven by human activity and greenhouse gas emissions stands out.
NASA Administrator Bill Nelson, stressed that the El Niño Phenomenon, which began in April 2023, also played a role in exacerbating extreme heat. However, the possible arrival of The girl It could change temperatures in much of the world and give the environment a break, according to the foreign institution.
In that sense, La Niña would partially cool global temperatures, although factors such as volcanic eruptions and aerosol emissions still influence climate predictions. The change in ocean temperatures, as a result of this meteorological event, is a factor for the increase in hurricane activity in the Atlantic.
Scientists at the National Oceanic and Atmospheric Administration’s Climate Prediction Center (NOAAfor its acronym in English) project a 49% probability that La Niña will occur develop between June and Augustand 69% that manifests between July and September.
Precisely, in Peruthe Multisectorial Commission in charge of the National Study of the El Niño Phenomenon (Enfen) has declared a state of “Coastal La Niña Watch”, predicting an anomalous cooling of the surface waters of the Pacific Ocean until the beginning of the last quarter of 2024.
Recently, Grinia Avalosdeputy director of Climate Prediction of the National Meteorology and Hydrography Service of Peru (Senamhi), warned about the possible effects on the coast, mountains and jungle of the national territory if La Niña occurs.
In the coast, the cooling of the sea could quickly be reflected in the climate of cities near the coast. “If these sea cooling anomalies consolidate and spread, this will condition that winter has a colder connotation than normal on the coast“said the official.
For the Mountain range and the jungledrier weather is expected and a possible delay in the start of the rainy season, which could cause droughts in spring. “That condition in the Peaceful “The central zone has indirect impacts on the global climate and for Peru it implies that there could be a lower presence of humidity in the mountains, especially the central and southern ones, as well as in the southern jungle, delaying the start of the rainy period,” he said.
Due to these conditions, the specialist warned about the risk of forest fires and recommended avoid agricultural practices as the burning of agricultural landwhich are usually carried out to “better oxygenate the land” before planting.
In addition, Ávalos stressed that La Niña could intensify frosts in the mountains and cold weather in the jungle, as well as certain circulation patterns typical of winter, such as DANA and high migration.
“We must be attentive to possible alterations in these typical autumn and winter patterns that could accentuate the events that always occur such as frost and cold,” he said.
“Last year we were in an El Niño event with degrees above normal and important records in the middle of autumn and winter. This year is the counterpart. We are entering a period of sea cooling after El Niño 2023-2024. What the population will perceive most is this contrast,” she concluded.
