2021年12月16日 · La Niña is a weather pattern that occurs in the Pacific Ocean. It changes ocean temperatures, causing severe weather conditions. The “cold event” causes winter temperatures to soar in the south but cool in the north. Climate-sensitive sectors like agriculture, health, water resources and disaster management are likely to be affected.

2023年3月2日 · 2022 marked the third consecutive La Niña year, which is highly unusual and has only occurred three times since records began in the 1950s. During La Niña events, global temperatures tend to be colder. Uncertain changes in La Niña and El Niño add up to an uncertain outlook for the future, say these climate scientists.

2023年2月20日 · La Niña is to blame instead, it says, as it increases the likelihood of high temperatures and lower rainfall. La Niña events normally occur every five years or so, but since 2019 the planet has seen an unusual ‘triple dip’ of three consecutive La Niña years, driving a prolonged period of low rainfall across South America.

2023年11月3日 · The weather phenomenon leads to warmer-than-average weather. El Niño impacts the equatorial eastern Pacific most strongly, but it also raises temperatures around the globe. In recent years, temperatures the world over have benefitted from the cooling effect of La Niña – “little girl” – which takes turns with her sibling.

2023年6月12日 · The weakening of La Niña and the expected increase in El Niño activity could have a significant impact on weather patterns around the world. Countries are racing to prepare for extreme weather later this year as the world tips into an El Nino — a natural climate phenomenon that fuels tropical cyclones in the Pacific and boosts rainfall and ...

2025年1月23日 · The climate is naturally variable (as evidenced in the El Niño and La Niña phenomenon), but scientific analysis has explicitly linked the anthropogenic cause behind extreme events such as flooding or wildfires. Climate change has resulted in changes in the duration, frequency, intensity and timing of weather extremes.

2022年9月21日 · Let’s take a closer look at how climate change and natural weather patterns like La Niña influence what we’re seeing around the world today. The June-August 2022 global land and ocean surface temperature was 1.6 degrees Fahrenheit (0.89 Celsius) above the 20th-century average of 60.1 F (15.6 C).

2023年6月7日 · Even if the weather pattern ends up boosting crop output in the Americas, the impact in Asia could reverberate across global food markets. Wheat prices dropped to two-and-half year lows this week, while corn and soybeans have eased from multi-year peaks set in 2022, when the Russia-Ukraine war and COVID-19 disrupted world supplies.

2022年3月11日 · La Nina conditions could continue into the Northern Hemisphere's summer. Image: NOAA The aviation industry needs to take "urgent action" to align with the world's climate goal, including curtailing growth in air travel and rapidly scaling up use of sustainable aviation fuels , a report on Thursday said.

2022年1月31日 · The La Niña weather pattern is here to stay, here’s what you need to know Zamora-Reyes was surprised by the team’s results. “I was expecting to see an increase in variability over the last 20 years at most,” she says, “but we’ve been seeing a …
