The arrival of the elk – another “what is nature?” story

My Journal colleague Charles Brunt had a fascinating tale in this morning’s Albuquerque Journal about the Bosque del Apache wildlife refuge’s struggle with elk. Located on the Rio Grande in central New Mexico, the Bosque is famous among birders, a winter home to a flock of some 10,000 sandhill cranes. It’s always been my personal …

The risks of risk communication

[A]n informed and properly motivated risk communicator would proceed deliberately and cautiously. In particular, because efforts to quiet public fears about vaccines will predictably create some level of exactly that fear, such a communicator will not engage in a high-profile, sustained campaign to “reassure” the general public that vaccines are safe without reason to believe …

In the eastern Mediterranean, tree rings tell of a shift toward stand-replacing fire?

In a Greek forest, tree rings telling a familiar story – a history of surface fire, but a trend toward much more destructive blazes: the size of the area burned as well as the type of fire seem to have changed, with the 2007 event being the most extended crown fire encountered so far. Our …

Anthropocene diaries: a fish story I wrote elsewhere

A forest burns down. Humans rescue fish, keep ’em alive in an Albuquerque warehouse. Maybe 80 years before the drainage that feeds their forest creek recovers. Maybe 200. This is life in the anthropocene: Angela James’ fish tanks don’t look much like Whiskey Creek. But for 68 imperiled Gila trout, the tanks in a northeast …

advice for climate communicators

from Dan Kahan: [W]hen positions on a fact that admits of scientific investigation (“is the earth heating up?”; “does the HPV vaccine promote unsafe sex among teenage girls?”) becomes entangled with the values and outlooks of diverse communities—and becomes, in effect, a symbol of one’s membership and loyalty in one or another group—then people in …

The Tree Rings’ Tale, as told by olives

As Kevin Anchukaitis put it, the Tree Rings’ Tale told by the olive tree is “Really really really really really really hard” to read. From Cherubini et al: Dendrochronological analyses of olive trees growing on the Aegean island Santorini (Greece) show that the determination of the number of tree-rings is impossible because of intra-annual wood density fluctuations, …

Old trees and the curse of Prometheus

There’s a romance about the tree ring lab, and the culture flowing therefrom, that seems to draw writers like me. It’s probably the same reason the sliced and polished slab of a tree’s trunk, marked with little flag markers pointing to moments in history (“Columbus lands”, “Declaration of Independence”) is such a museum of natural …

So what exactly do we mean by “drought”?

The Sheffield et al drought paper in Nature that I blogged quickly about a couple of days ago has triggered all kinds of fascinating discussion among folks in the southwestern US “drought community” (yes, there is such a thing). In brief, Sheffield and colleagues argue that a careful application of the Palmer Drought Severity Index suggests …
