January sets record high temperature despite La Nina's cooling effects
ai generated text
January 2024 was reported as the warmest January on record by the Copernicus Climate Change Service, with surface-air temperatures 1.75C above pre-industrial levels. This heat was expected to subside after a warming El Nino event peaked in January 2024, but it has persisted at record or near-record levels. La Nina, a phenomenon in the Pacific Ocean, typically eases warming, but its effects have been outweighed by the lingering heat. Scientists are exploring the possibility that Earth's surface chemistry may have undergone a change, in addition to the impact of greenhouse gas emissions, which are the primary driver of global warming and reached record levels in 2023 and 2024.
January 2025 is another surprising month, continuing the record temperatures observed throughout the last two years … Copernicus will continue to closely monitor ocean temperatures and their influence on our evolving climate throughout 2025.
This is what makes it a bit of a surprise ... you're not seeing this cooling effect, or temporary brake at least, on the global temperature that we were expecting to see.
This heat is bound to resurface periodically. I think that's also one of the questions: is this what has been happening over the past couple of years?
