Early-onset of springs indicate `nightmare` for agriculture

Washington D.C. [USA], Sept. 3 (ANI): A recent study has revealed that warm springs in the Great Lakes and Northeast regions which create havoc for agriculture may start earlier by mid-century if greenhouse gas emissions are not reduced.

Very warm springs have been anomalies, but this new analysis of climate model data shows an increased frequency to nearly one in every three years by the end of this century.

Assistant professor Toby Ault said, "The spring of 2012, with its summerlike warmth, brought plants out of dormancy and then had a lengthy freeze. This was a nightmare scenario for many growers, and it showed us a snapshot of what global warming might look like in this region."

Unusually warm temperatures early in spring 2012 led to the warmest March, breaking records in more than 15,000 U.S. sites.

Modelling shows that frequency and magnitude of early springs could occur more than a month earlier, for example, throughout the Great Lakes region by 2080.

"The time to act on curbing greenhouse gas emissions is now. If we don't, years like 2012 - ruinous to farmers and producers - in the U.S. could become normal by 30 to 40 years from now in addition to a host of other impacts," said Ault.

The researchers sought to understand seasonal-transition timing to offer strategies as climate change unfolds.

To ensure their models are accurate, Ault said the researchers distinguished and separated normal climatic variability from long-term atmospheric alterations by using a new ensemble of climate change simulations.

After a warm winter 2011-12, some orchards blossomed earlier than usual that spring.

Temperatures tumbled in April and crops were destroyed.

The study was published in Climate Dynamics. (ANI)
