Climate change has exacerbated these extremes, specialists say.

“We have made it worse” with local weather change, mentioned Mark Cane, a professor of earth and environmental sciences at Columbia University.

South America has been hit particularly arduous by what Crane calls the “one-two punch of El Niño plus global warming.”

Here are 5 of the methods El Niño has been impacting the continent.

Fires in Colombia threaten distinctive plant

High in Colombia’s Andes mountains is a plant referred to as the frailejón. Growing to concerning the peak of an grownup human, it’s recognized for its crown of fuzzy leaves that siphon moisture from fog. The plant turns the haze into water that replenishes native watersheds.

But frailejónes are in peril on account of an unprecedented fireplace season throughout elements of Colombia’s Andes which are normally temperate, cool and moist. The crops solely develop at sure altitudes and take a long time to mature, elevating fears that the wildfires might decimate the species that has withstood years of different turmoil within the nation.

Frailejónes are so beloved in Colombia {that a} frequent youngsters’s tune options them. An Instagram account with greater than 100,000 followers is devoted to the plant; a latest put up confirmed a distressed cartoon frailejón surrounded by fireplace, with the caption, “Forest fires are no joke.

Dengue rages amid warmth waves in Peru

El Niño obtained its identify in Peru, the place, the story goes, fishermen observed the climate sample round Christmastime. They named the phenomenon “el niño de la navidad.”

This newest El Niño has been blamed for fueling a large surge of dengue instances amongst individuals in Peru.

Heavy rains linked to the climate sample have been a boon to the nation’s mosquito inhabitants final yr, producing Peru’s greatest dengue outbreak on file. More than 270,000 instances have been reported, overwhelming hospitals in some areas. There have been at the least 381 dengue-related deaths.

And now, hotter than regular temperatures are once more creating “favorable environments for dengue transmission,” the U.N. Office for the Coordination of Humanitarian Affairs mentioned in a regional replace on Friday.

Dengue instances in Peru in 2024 are up greater than 53 p.c from final yr, OCHA mentioned, citing figures from Peru’s well being ministry. The surge, it mentioned, “coincides with prolonged El Niño-induced heat waves.”

Amazon river dolphins die en masse

The our bodies of greater than 150 pink river dolphins have been present in unusually heat waters in Lake Tefé within the Amazon this fall, when a few of the extra pronounced results of El Niño emerged.

Scientists mentioned that the trigger was not instantly clear however that excessive warmth and drought introduced on by El Niño and local weather change have been prone to blame. Water ranges had fallen considerably, and the temperature within the lake had reached 102 levels Fahrenheit.

The heat water disorients the dolphins, Claudia Sacramento, head of the Environmental Emergencies Division on the governmental Chico Mendes Institute for Biodiversity Conservation, instructed The Washington Post on the time. And then a lack of oxygen basically suffocates them, Sacramento mentioned.

A research by the World Weather Attribution initiative assessed that local weather change was principally guilty for the “exceptional drought” within the Amazon River Basin. The research, launched final month, discovered that El Niño and local weather change have been equally chargeable for the loss in precipitation, however {that a} “strong drying trend was almost entirely due to increased global temperatures.”

Fires in Chile devastate communities

A rash of wildfires killed at the least 131 individuals this month, in keeping with Chilean authorities. President Gabriel Boric declared a state of emergency, and the nation entered a interval of mourning.

Authorities are investigating suspicions that at the least a few of the fires have been set deliberately. But specialists say heat, dry circumstances introduced on by El Niño and local weather change created ripe circumstances for the fires to unfold so simply.

This was “believed to be Chile’s deadliest forest fire on record,” the U.N. Office for Disaster Risk Reduction mentioned, “with expectations that the death toll will grow.” Hundreds of individuals are nonetheless lacking.

Chile’s lethal wildfires worn out neighborhoods. One stood unscathed.

Drought, then floods, hit Bolivia

Bolivia is “facing a severe crisis due to a combination of intense winter heat fueled by the climate crisis and the El Niño,” OCHA mentioned in a memo in October. The drought and extreme warmth pressured authorities to problem warmth advisories and warnings to take heed to water use.

Then the wet season got here. But the welcome moisture final month hit parched land, which is much less geared up to soak up rain, inflicting flooding that left at the least two individuals lifeless and displaced a whole bunch extra, OCHA mentioned.

The World Food Program famous that sure demographic teams in Bolivia, corresponding to Indigenous individuals and girls in rural areas, have been notably inclined to shocks attributable to local weather change.

Amir Jina, an assistant professor on the University of Chicago who researches the socioeconomic impacts of modifications within the surroundings, mentioned local weather change was pushing the bounds of the El Niño throughout thresholds the place “social impacts,” corresponding to agriculture and meals safety, turn out to be negatively impacted.

“The more we shift up this average, the more we’re going to start seeing things like El Niño have much larger negative impacts on society,” he mentioned.
