La Niña conditions are currently forming in the Pacific Ocean, however forecasters expect that if these conditions persist through the winter, this will only be a mild episode, compared to La Niña that have occurred in the past.

La Niña, Spanish for "little girl", occurs when sea surface temperatures drop to below normal along a band following the equator in the Eastern Pacific, the counterpart to the phenomenon of above-average sea surface temperatures known as El Niño. These two phenomena are part of the El Niño-Southern Oscillation (ENSO), one of the strongest drivers of climate variation in North America and around the world.

Not only is this positive news in regards to our atmosphere’s ability to filter out harmful UV radiation, it also stands as an example of how humanity can make a positive, large-scale impact when efforts to reduce ecological harm are required, such as in the case of our need to reduce greenhouse gas emissions.
