Flowers bloom earlier because the earth warms

Dozens of flowers in the United States bloomed the earliest in the past 160 years due to climate change.

At least 32 species of flowers in the United States hatch earlier than 24 days in 2010 and 2012 because of rising temperatures.

Elizabeth Ellwood, a researcher at Boston University in the United States, and her colleagues analyzed data on the batch time of 32 flowers at two locations over the past 161 years, Livescience reported.

The team took data from famous naturalists Aldo Leopold and Henry David Thoreau. Earlier many scientists described the data of Leopold and Thoreau, but Ellwood was the first to combine their data.

"The record temperature in 2010 and 2012 makes 32 species bloom 10 to 24 days earlier than other years," Ellwood concludes.

Due to an area that Ellwood's team studied on the coast, there was an area in the interior of the country, so they thought that the results of the study could be true for the entire United States.

A previous study showed that climate change makes spring come earlier on continents. For example, in 2009, spring came 1.7 days earlier than the first half of the 20th century. Summer, autumn and winter also started 1.7 days earlier. In addition, the temperature difference between winter and summer is decreasing. The shift of time of the seasons takes place uniformly on land, but on oceans this phenomenon does not occur.
