Scientists say El Nino is on the verge of impacting weather around the world and likely playing a role in the climate crisis. According to scientists, this phenomenon will be associated with new temperature records that await us in the coming years, according to IFLScience..

The latest report from the National Oceanic and Atmospheric Administration (NOAA) reveals rising sea surface temperatures in the tropical Pacific. This indicates that " In addition, these observations confirm previous warnings from the World Meteorological Organization..

The Southern Oscillation is a fluctuation in surface water temperatures in the South Pacific Ocean.. It affects the climate of the whole world - from wind, temperature and precipitation patterns to the intensity of the hurricane season and even the distribution of fish in the sea..

Every few years conditions change from a warm phase, El Nino, to a cool phase, La Nina.. Winds weaken along the equator during El Nino. Warm water is being pushed east towards America's west coast. As a result, less cold water rises to the surface..

And it has a profound effect on the global climate.. Warmer waters cause the Pacific Jet Stream to move south and expand, resulting in drier weather in the northern United States and Canada and wetter weather in the south..

Since September 2020, we have been living in La Nina conditions, but this year the situation has begun to change and many forecasts show that we are moving to the El Nino phase.

And El Nino could lead to new temperature records to be set in the coming years.. If El Nino is strong, it could lead to new unprecedented heatwaves in 2023-24. And they, in turn, will lead to new global temperature records..

“Given how warm the oceans are, a developing El Nino will only increase the likelihood of record global ocean temperatures (and global average temperatures for both ocean and land), which is likely to have important environmental impacts, including for fish and corals.”.

Earlier, scientists conducted simulations of the future of the Earth until 2100 and revealed how much gradual changes in temperature and precipitation can change the climate at the local level.. These changes will be so dramatic, they say, that it will probably be the first time we've had to redraw maps since the 1880s..
