DENNIS PATRICK: LA NIÑA IT IS |
“Global warming! Climate Change!” cry the Chicken Littles on the left. “The sky is falling!”
Not so fast. Hundreds of years before the industrial revolution South American fishermen recognized the fluctuation of warm and cool waters along the coast of Peru and Ecuador. The pattern remains. Not until the 1920s did a British meteorologist, Sir Gilbert Walker, identify and record the fluctuations. He theorized that the association between water temperatures and atmospheric conditions created cyclical weather patterns leading him to conclude what he dubbed the ENSO.
The La Niña of winter and spring 2021 brought drought to the northern plains. Very little winter snow fell. Likewise, scant spring rain. This poses a substantial fire danger. With pasture grass scarce for cattle and crop planting delayed, agriculture takes a hit. The southern plains, on the other hand, experienced a reasonably moist winter continuing into spring 2021. All this thanks to La Niña.
