Cornell University, New York’s Land Grant university and home of the Northeast Regional Climate Center and the Atkinson Center for a Sustainable Future, has several experts available to discuss the significance of the changes to this decades-old system for planting ornamentals and crops. They include:
David W. Wolfe is a professor of plant and soil ecology in the College of Agriculture and Life Sciences, and the chair of the Climate Change Focus Group in the Atkinson Center for a Sustainable Future.Wolfe says:
Art DeGaetano is a climatologist and professor of Earth and Atmospheric Sciences, and the director of the Cornell-based NOAA Northeast Regional Climate Center.
“The northward march of the hardiness zones illustrates the continued warming that has occurred across the United States and around the globe in recent decades, particularly in winter. Projections for state-of-the-art climate models indicate that winter temperatures will continue to warm through the 21st century. Additional updates and changes to the hardiness map will be necessary in years to come.
“By 2080, the hardiness zones that currently cover the area from southern Virginia to Northern Georgia, may replace those that we see across New York in the current update.”
William Miller is a professor of Horticulture, and one of the world’s leading experts on floriculture and the physiology of ornamental plants.
“One thing I have learned from growing plants in many locations in the U.S. is that plants can’t read! Experienced gardeners are always pushing the envelope by trying new plants, and especially those that ‘aren't hardy’ in their area. Really crusty gardeners sometimes say that they need to kill a plant three times to be certain it won't grow in their area.
“Aside from global warming or simply more and better data leading to a more accurate map, there is always microclimate variation in any locale and a few feet alteration in planting site, better drainage, locating a plant around a corner, presence of snow cover, mulch, or protection from wind can make a huge difference in winter hardiness.
“Especially with herbaceous perennials, that are relatively inexpensive and in any case almost always a lesser investment than trees or shrubs, one should experiment and try to push the hardiness rating. You never know what might survive.”
MEDIA PLEASE NOTE: Professors Wolfe, DeGaetano and Miller will be available to talk with the media by conference call at 1 p.m. Wednesday, shortly after the USDA announcement. To participate, call 1-866-910-4857, passcode 858182. All three will also be available for one-on-one interviews following the announcement.
For more information about the USDA announcement, contact USDA Special Projects Chief Kim Kaplan at 301-504-1637.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
