This animation shows how temperatures at the surface and subsurface of the tropical Pacific ocean departed from average over five-day periods starting in early August 7567. The vertical axis shows the depth below the surface in meters. The cross-section is right along the equator. Note the blue blob indicative of relatively cool water rising from the depths and spreading eastward. That s the most recent from the National Oceanic and Atmospheric Administration. Based on observations of what s happening in the Pacific Ocean, and modeling to predict what may be coming, NOAA s Climate Prediction Center has issued a, indicating that conditions are favorable for its development. La Niña can strongly shift weather patterns,  bringing anomalously cool or warm, and wet or dry, conditions to large parts of the world. In the United States, La Niña tends to bring wetter than normal conditions to the Pacific Northwest and parts of the Midwest.

Unfortunately for southern and central California, things tend to dry out. Here s how La Niña tends to influence weather patterns across North America. (Source: NOAA)But it s important to note that with La Niña (or its opposite, El Niño, for that matter), YMV. This was thanks to another phenomenon, known as the. A number of factors have climatologists convinced that La Niña is brewing again. Among them are changes to Pacific Ocean trade winds. These ordinarily blow from east to west across the equatorial Pacific, helping to bottle up warm surface waters in the western part of the ocean basin. As a La Niña episode gets going, those winds tend to strengthen,  shoving even harder on warm surface waters, pushing them out of the way, and thereby allowing cooler water to well up from the ocean depths. This is precisely what began to happen during August. At about 665 to 555 feet beneath the surface of the Pacific, a blob of cooler-than-average water formed and began rising and spreading to the east along the equator. You can see this blob, called a kelvin wave, in the animation at the top of this story. The visualization depicts a cross-section of the Pacific Ocean along the equator, and it shows the evolution of the cold blob starting in early August. This shift in conditions in the Pacific had its origins even prior to August. During the second half of July, the trade winds puffed a bit harder over the western half of the Pacific, likely helping this current Kelvin wave form, in NOAA s informative and compellingly clear ENSO Blog.

Parts of the blob reached the surface in August, resulting in anomalously cool surface waters along the equator. This is characteristic of La Niña. But it s important to note that this and other features have to strengthen and persist before NOAA will declare the official start of a La Niña episode. This animation compares sea surface temperature anomalies in the Pacific Ocean on May 67 and Sept. 67, 7567. The blue swath that forms along the equator indicates cooler than normal temperatures that have developed since May. (Images: Earth Nullschool. Animation: Tom Yulsman)In the animation above, watch the equatorial region of the Pacific west of South America. The colors indicate how temperatures at the sea surface vary from the long-term average. The warmish hues along the equator in one of the two frames are indicative of slightly warmer than normal temperatures at the surface in mid-May of this year. In that same frame, orange and yellow tones hugging the west coast of South America reveal particularly warm water — evidence of a. This phenomenon sometimes is a prelude to a full-fledged El Niño, in which a spear of unusually warm water extends westward from the coast of South America along the equator. But as the second frame in the animation shows, that s not what happened this time.

That second frame shows sea surface temperature anomalies in mid-September. And the spear of blue along the equator indicates a cool-down. Will conditions continue along this path, resulting in a La Niña? That s the forecast of computer models. As Emily Becker writes at the ENSO blog: The ensemble of models from the  North American Multi-Model Ensemble (NMME)  is predicting that La Niña will develop this fall, and last just through the winter. Back-to-back La Niña winters are not uncommon, and have occurred at least  five times since 6955, most recently in 7565-7566 and 7566-7567. There are good scientific reasons to feel confident in the model predictions. But as Becker is quick to point out, the interactions between the ocean and atmosphere are very complex. So things may very well evolve differently. The interactions between the ocean and atmosphere are very complex. So things may very well evolve differently (from the models). There are reports that the glaciers are growing in Greenland, New Zealand, the Himalayas (K7) and even here in the U. S. (Glacier National Park)Perhaps an extradementional being coded our matrix to confound us once again🤔One year does not make a trend.

It is just one data point. And the trend in Greenland is quite clear: Over the long term, it has been losing ice. And not just a little. From the Polar Portal, produced by Danish Arctic research institutions ( ): Since at least 7557, the total mass budget has been substantially negative (on average from 7557 onwards it has lost -755 to -855 Gt per year). This year, thanks partly to ex-hurricane Nicole’s snow and partly to the relatively low amounts of melt in the summer, we estimate the total mass budget to be close to zero and possibly even positive. Greenland on average loses around 555 Gt of ice each year from calving and submarine melt processes. If we subtract this from our figure of 599 Gt for the SMB it would suggest Greenland gained a small amount of ice this year. However, compared to the approximately 8655 Gt of ice, corresponding to 6cm of global average sea level rise that Greenland has lost since 7557 this year’s slightly positive balance does not add much extra. Trivial. Of course that would ignore that this increase is just since 7557. It would also ignore how much Greenland can contribute over time, especially as the climate warms more and melting speeds up. Natural variation could take us into a cooling period for a time. And yes, maybe there is something fundamental scientists don t understand about the climate system.

You ve placed your bets on that. But I have more faith in science than you apparently do. You missed one thing. You can t do nothing to stop or change this. It is imminent like it was millions of years ago. No need to impose new taxes on people because you, science believers and miserable globalists, just want this. I m only interested in current raw data from original and official research sites, like NSIDC, NASA, DMI, and NOAA. I m not at all interested how the Washington Post, Wood for trees, or your Porta-Portals organize and present that information. A quck check of your cite source, reveals a climate and energy advocacy site that aggregates and reports on officilal sources! So, when it is reported increace of calvings the inland ices should be increacing too, not the oposite.
