Taxonomic groups have differed in their responses , and a few have completely diverged from general trends. For example, seabirds continue to breed with their pre-climate-change phenologies . Newer reviews and analyses reveal differences in responses across continents and time intervals . Mean advance in days per decade for plants was 5.5 in China and 3.0-4.2 in Europe, but only 0.9 in North America . Mean values for the retardation of autumn leaf fall, which can be more influenced by photoperiod and less by temperature than spring leaf-out, were 0.36 days per decade in Europe , 2.6 days per decade in China and around 3 days per decade in the USA  .
