In the United States, early spring made its way through winter a few weeks earlier than expected. Tulips, crocuses and many other plants are blooming earlier than expected, starting from Arizona to New Jersey and then down to Florida. Washington was invaded by a wave of premature pink blossoms in the trees. This spring, the early birds which showed up are woodpeckers, grackles, and red-winged blackbirds.
On February 28, scientists stated that this unnatural warm weather at this time of the year defies the calendar. Researchers at the U.S. Geological Survey’s National Phenology Network claimed that they have already calculated the local and national spring index after analyzing honeysuckles, lilacs and temperature records which are sent to a computer.
The spring leaf index kept records from 1900. The year 2012 is known to have been the earliest one on record. Nevertheless, new data registered indicates that preliminary records from this year suggest that this year’s records surpass the records recorded in 2012. Due to global warming, spring appears to take over nature a lot earlier than usual.
However, not every area in the US can enjoy the early spring. For a broad area of the United States, 2017 appears just like a flower which blooms at the beginning of February. Even if Indianapolis, Columbus, Pittsburgh, Atlanta, Washington, St. Louis, and Nashville are three weeks early on the spring index, there are regions like Los Angeles and Phoenix which remained behind.
In Ohio, Columbus, Indianapolis, and Pittsburgh, spring arrived a lot earlier compared to the last thirty years. Spring sprung twenty days earlier in these areas compared to the results obtained in 2012. It is obvious that all these out-of-order events happen due to global warming which affected the general climate of the entire globe.
The maps developed by the US Geological Survey which is updated every day are bound to reveal how early spring arrives every year. The maps are based on events like the occurrence of leaves on trees, the first flowers blooming. The USGS indicated that an early spring is one of the signs of a warming planet. The records have previously shown that 201 6 was known to be the hottest year which was ever recorded. An early spring may have all kinds of wide-ranging effects on agriculture and human health.
