A La Nina weather front is formed when strong winds blow the warmer surface waters from the Pacific ocean away from the South American continent and towards the Philippines, this allows colder waters to come to the surface, reducing the sea-surface temperatures in those areas of the planet by 1-2C. However, in a blog published on the Met Office website, all scientists agree that the presence of greenhouse gases in the atmosphere will still contribute to record global temperatures. “Met Office scientist, Dr Nick Dunstone said: “The variability of the La Niña / El Niño cycle is the second most important factor in determining the Earth’s temperature but it is simply dwarfed by the forcing effect of increasing greenhouse gases in the atmosphere.” Global temperatures have risen consistently over the past seven years and since 2016 have averaged above 1C. Prof. Adam Scaife, Head of Long Range Prediction at the Met Office said, “The global temperature for 2021 is unlikely to be a record year due to the influence of the current La Niña, but it will be far warmer than other past La Niña years such as 2011 and 2000 due to global warming.”
