A long-awaited La Nina has finally appeared, but the periodic cooling of Pacific Ocean waters is weak and unlikely to cause as many weather problems as usual, meteorologists said Thursday. La Nina, the flip side of the better-known El Nino, is an irregular rising of unusually cold water in a key part of the central equatorial Pacific that changes weather patterns worldwide. The last El Nino was declared finished June 2024, and National Oceanic and Atmospheric Administration (NOAA) forecasters have been expecting La Nina for months. Its delayed arrival may have been influenced by the world's oceans being much warmer than the last few years, said Michelle L'Heureux, head of NOAA's El Nino team. It's totally not clear why this La Nina is so late to form, and I have no doubt it's going to be a topic of a lot of research, L'Heureux said. In the United States, La Ninas tend to cause drier weather in the South and West. They tend to make weather wetter in parts of Indonesia, northern ...
Earth's string of 13 straight months with a new average heat record came to an end this past July as the natural El Nino climate pattern ebbed, the European climate agency Copernicus announced Wednesday. But July 2024's average heat just missed surpassing the July of a year ago, and scientists said the end of the record-breaking streak changes nothing about the threat posed by climate change. "The overall context hasn't changed," Copernicus deputy director Samantha Burgess said in a statement. "Our climate continues to warm." Human-caused climate change drives extreme weather events that are wreaking havoc around the globe, with several examples just in recent weeks. In Cape Town, South Africa, thousands were displaced by torrential rain, gale-force winds, flooding and more. A fatal landslide hit Indonesia's Sulawesi island. Beryl left a massive path of destruction as it set the record for the earliest Category 4 hurricane. And Japanese authorities said more than 120 people died in
India is grappling with unprecedented heat this summer and no one is prepared for the level of warming being experienced, leading environmentalist Sunita Narain has said, emphasizing the need for a heat index and a complete overhaul of the way modern cities are designed. In an interaction with PTI editors here, Narain, the Director General of the Centre for Science and Environment (CSE), said the brutal heat scorching swathes of India is a result of naturally occurring El Nino phenomenon -- an unusual warming of the ocean surface in the central and eastern tropical Pacific Ocean -- and climate change. "Nobody is prepared. Let's be very clear. 2023 was globally the hottest year on record. We have broken every record in the last 45 days with an unbroken (streak of) temperatures above 40 degrees. This is climate change. It is compounded this year by the waning of the (2023-24) El Nino. This means we really need to get our act together. We need to ensure that vulnerable communities are .
The strong El Nino weather condition that added a bit of extra heat to already record warm global temperatures is gone. It's cool flip side, La Nina, is likely to breeze in just in time for peak Atlantic hurricane season, federal meteorologists said. The National Oceanic Atmospheric Administration Thursday pronounced dead the El Nino that warms parts of the central Pacific. The El Nino, while not quite a record breaker in strength, formed a year ago has been blamed, along with human-caused climate change and overall ocean warmth, for a wild 12 months of heat waves and extreme weather. The world is now in a neutral condition when it comes to the important natural El Nino Southern Oscillation, which warps weather systems worldwide. Neutral is when weather gets closer to long-term averages or normal, something that hasn't happened as much recently as it used to, said NOAA physical scientist Michelle L'Heureux, who is the lead forecaster of the agency's ENSO team. But it likely won't ...
Heatwaves similar to those experienced in May in India are almost 1.5 degrees Celsius warmer than the warmest heat waves previously observed in the country, according to a new rapid attribution study by an independent group of climate scientists and researchers. The analysts at ClimaMeter said the intense and prolonged heat wave India endured in May was a result of the naturally occurring El Nino phenomenon -- unusual warming of the ocean surface in the central and eastern tropical Pacific Ocean -- and the rapidly increasing concentration of greenhouse gases -- primarily carbon dioxide and methane -- in the atmosphere. The researchers analyzed how events similar to the high temperature in India's May heatwave changed in the present (20012023) compared to what they would have looked like if they had occurred in the past (19792001). "The temperature changes show that similar events produce temperatures in the present climate at least 1.5 degrees Celsius warmer than what they would hav
