A New York story: not all the tree rings’ tales are about drought

Andrew Freedman had an interesting piece last month about tree ring research that’s different than the stuff I usually write about: The past several decades have been the wettest in nearly five centuries for the watershed serving the nation’s largest city, New York, according to a new study. But that wet period is deceiving because …

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 …

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 …

Stuff I wrote elsewhere: where the water will run out

2013 has the potential here in New Mexico to be a great laboratory for exploring the question of specifically where and when water supply shortages actually play out during a drought year. I took a crack in this morning’s paper at setting up the problem, highlighting what I see as the four key New Meixco …

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 …

Running the table: dry at all relevant time scales

I confronted a litany of drought when I was making the rounds on my newspaper beat this morning. No doubt this has happened before and I’ve just not noticed it, but the current forecasts are dry at all the basic time scales I watch closely. I lined ’em all up so you could share New …

Stuff I wrote elsewhere: climate change on the Colorado River

The science accumulates: The more greenhouse gases push up temperatures over the next few decades, the more New Mexico’s water supplies are at risk, according to new research by a team of Columbia University scientists. Using the latest high-resolution global climate simulations, the scientists show evaporation caused by warming temperatures is likely to leave less …

Record dry 2012 at my house

I’ve been keeping rainfall records as a volunteer National Weather Service observer since 1999. 2012 is the 13th calendar year for which I have complete records for my house, in Albuquerque’s near northeast heights, about a mile northeast of the University of New Mexico. It was my driest on record, at 5.08 inches (12.9 cm). …

“My Vanishing Hometowns,” a climate change storytelling project

I first met Christy George a couple of years back on the edge of a lovely lake outside Stockholm, where we spent two glorious days kicking around the joys and struggles of environmental storytelling. Christy is the former president of the Society of Environmental Journalists, a public broadcasting news veteran and a clever teller of …
