A tree crew removes a large Live Oak from Abercorn Street at 49th Street after the remnants of Hurricane Helene impacted the Savannah area on on Friday, September 27, 2024. ‘Just very short-sighted'
The divergence problem is an anomaly from the field of dendroclimatology, the study of past climate through observations of old trees, primarily the properties of their annual growth rings. It is the disagreement between instrumental temperatures (measured by thermometers ) and the temperatures reconstructed from latewood densities or, in some ...
Reports of carcinomas in sharks exist, and current data does not support any conclusions about the incidence of tumors in sharks. [74] Great white sharks do not mistake human divers for seals or other pinnipeds. When attacking pinnipeds, the shark surfaces quickly and attacks violently.

The Savannah Tree Foundation's new nursery allows it to cultivate local seedlings that will more easily adapt to the area's characteristics.
The divergence problem is the disagreement between the temperatures measured by the thermometers (instrumental temperatures) on one side, and the temperatures reconstructed from the latewood density or width of tree rings on the other side, at many treeline sites in northern forests.
