Global warming hiatus Global warming hiatus A global warming hiatus, also sometimes referred to as a global warming pause or a global warming slowdown, is a period of relatively little change in globally averaged surface temperatures. In the current episode of global warming many such 15-year periods appear in the surface temperature record, along with robust evidence of the long-term warming trend. Such a "hiatus" is shorter than the 30-year periods that climate is classically averaged over. Publicity has surrounded claims of a global warming hiatus during the period 1998–2013. The exceptionally warm El Niño year of 1998 was an outlier from the
Visual Word dependent on natural languages and this ones have a limit to the number of terms and words, there are important needs to reduce the number of visual words. A number of solutions exist to solve this problem, one of them is to divide the feature space into ranges, each one having common characteristics (which can be considered as a same word), nonetheless this solution carries many issues, like the division strategy, the size of range in the feature space, etc. Another solution proposed by researchers is using a clustering mechanism to classify and merge words carrying common information in a
