The core is a Picea rubens whose inner ring is 1905. The inner ring of of a 2nd core from this tree is 1721. If one extrapolated rings to pith using inner 10 ring widths and estimated distance to pith, I’d guess you’d be off 150 years, essentially two centuries off Careful when extrapolating ages

Fifty shades of fade: linking transmittance loss to cellular death during leaf dehydration
Drought-induced tree mortality is associated with hydraulic failure and subsequent cell death. Leaf vitality is a critical indicator of tree water stress; however, current methods for assessing ce...

The science is clear. The stakes are real. AGU condemns the repeal of the EPA Endangerment Finding — a decision that rejects the overwhelming evidence and undermines climate accountability. We will continue to defend science and advocate for evidence-based policy. buff.ly/wX1BQ2t

Hurricanes are getting stronger: This study found from 1992-2021, Cat 1+ hurricanes globally intensified by 1.74 m/s (3.9 mph) over the 30-year period, and that a cold bias in IPCC climate models "probably contributes to an underestimate in projections of major hurricane frequency.”
