![]() ![]() "As warmer-than-average sea surface temperatures are generally predicted over oceanic regions, they contribute to the widespread prediction of above-normal temperatures over land areas," the WMO recently said in its regular Global Seasonal Climate Update (GSCU) for July, August and September. Earth's thermosphere reaches highest temperature in 20 years after being bombarded by solar storms Watch lightning crackle over Europe and Africa in stunning video from powerful new weather satellite Satellites observe record-breaking marine heatwave hit North Atlantic This, coupled with atmospheric observations, strongly hinted at the onset of El Niño conditions.Ī fully established connection between ocean and atmosphere temperatures could take another month to fully couple in the tropical Pacific. The last La Niña ended in March 2023.Ī month prior to the end of La Niña, average sea surface temperature anomalies in the central-eastern equatorial Pacific rose from nearly half a degree below average in February to around almost a full degree above average in mid-June. The effects of El Niño are generally considered to be the opposite of those of another climate-driving event, La Niña, periods of cooler than average sea surface temperature in the equatorial Pacific. On the flip side of this, the phenomenon is believed to lead to severe droughts across Central America, northern South America, Australia, Indonesia, and parts of southern Asia. (Image credit: WMO) El Niño and La Niña in 2023Įl Niño events are usually linked to an increase in rainfall and even flooding in parts of the southern U.S., southern South America, the Horn of Africa and Central Asia. "However, it is yet another wake-up call, or an early warning, that we are not yet going in the right direction to limit the warming to within the targets set in Paris in 2015 designed to substantially reduce the impacts of climate change."Īn infographic showing the rainfall conditions associated with El Niño periods. ![]() "This is not to say that in the next five years, we would exceed the 1.5☌ level specified in the Paris Agreement because that agreement refers to long-term warming over many years," WMO Director of Climate Services Chris Hewitt said. The report also suggested there is a 66% possibility that the annual average near-surface global temperature will, at some point between 20, reach 1.5 degrees above pre-industrial levels for at least a year. In a report published in May this year, the WMO was already predicting a 98% chance that one of the next five years, and this five-year period as a whole, would be a record-breaker in terms of global temperature, displacing 20 from the top spot as the warmest years on record. ![]() This occurs on average every 2 to 7 years in bouts that last between 9 and 12 months.ĭespite the fact that El Niño is a natural phenomenon, it can't be viewed in isolation from human-driven (anthropogenic) climate change. (Image credit: WMO) El Niño is a "wake-up" call about climate change targetsĪccording to the Met Office in the U.K., El Niño conditions are declared when sea temperatures in the tropical eastern Pacific rise half a degree above the long-term average. However, the forecast is subject to change.An infographic from the WMO showing a 90% probablity that El Niño conditions will last until the end of 2023. Here's where the northern lights could be visible: that are predicted to see the lights are forecast to see them on the horizon. Last week's forecast called for aurora borealis visibility in 17 states, including parts of North Dakota, Minnesota, and Indiana, but it has since been updated to eight states in the U.S. The northern lights could be visible in northern parts of eight states if the weather is clear. Want to see the northern lights? Good news: Experts predict years of awesome aurora viewing. The Space Weather Prediction Center's forecast Wednesday showed potential for people in the northern part of the country to possibly see the auroras on the horizon. "The collisions produce light much like how electrons flowing through gas in a neon light collide with neon and other gases to produce different colored light bulbs." "Aurora is the name given to the glow or light produced when electrons from space flow down Earth’s magnetic field and collide with atoms and molecules of the upper atmosphere in a ring or oval centered on the magnetic pole of Earth," the website says. The natural phenomenon is usually caused by solar winds coming from the sun and Earth's magnetic field, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center. The forecast is a change from the number of states that were predicted to possibly see the lights last week. The northern lights, also known as the aurora borealis, could be visible in some U.S. If seeing the northern lights is on your bucket list, you might just be in luck. ![]()
