According to a new report by the UNH scientist, the beginning of 'natural spring' starts a week ahead than before. // The effect, which is a result of global warming, has made an impact in the entire natural occurrence, thereby creating a ripple effect in all the happenings takes place in nature.
The sun will still cross the equator on March 20th marking the vernal equinox and the official start of spring, but Mother Nature is increasingly getting a jumpstart on the celestial movements. Over the last 150 years, scientific measurements show that events signifying the beginning of spring have all shifted.
These events now happen about a week earlier on average in the northeast United States, according to a new report, Evidence of Early Spring, from the group Clean Air-Cool Planet (CA-CP), which today announced the new, first day for “natural spring,” March 13. The group, along with University of New Hampshire climate scientist Cameron Wake, Tim Flannery, author of the book The Weather Makers, and professor David Wolfe of Cornell University, conducted a call-in press conference today to discuss the issue and announce spring’s new “arrival.”
“Of course, the sun will still cross the equator on the 20th, marking the vernal equinox, but biological spring has changed due to global warming and that’s threatening to put ecosystems badly out of synch,” Markham said.
Evidence of Early Spring follows a comprehensive report issued collaboratively in March 2005 by CA-CP and Wake entitled Indicators of the Climate Change in the Northeast, which looked at 11 different physical and biological markers of the changing climate in the region.
Indicators of the Climate Change in the Northeast noted that the average Northeast winter temperature has increased 4.4 degrees Fahrenheit from 1970 to 2000. During that same period, the growing season increased by 15 days and days with snow on the ground decreased by 16. For the coastalPage: 1 2 3 Related medicine news :1
