Climate change’s impact on forests being measured via expanding tree trunks (Wash Post)

[Editor's note: Humorous but scientific take on "tree huggers" in the U.S. mid-Atlantic. Catching up on some old clippings as I roll back into DC.]

Jess Parker hugs trees.

In the woods of Anne Arundel County, he throws his arms around tulip poplars, oaks and American beeches, and holds them so tightly that his cheek presses into their bark. This is not some hiker on a lark: anybody, hopped up on campfire coffee and exercise endorphins, might hug a tree once.

This is science. Parker has done it about 50,000 times.

Parker, a forest ecologist at the Smithsonian Institution, has spent the past 22 years on a research project so repetitive, so time-consuming, that it impresses even researchers with the patience to count tree rings. Since 1987, he and a group of volunteers have embraced thousands of trees, slipped a tape measure behind them, and wrapped it around to measure the trees’ girth.

This year, after about 250,000 hugs between them, the work paid off.

Parker’s data, which showed the trunks gradually fattening over time, indicated that many of the trees were growing two to four times faster than expected. That raised questions about climate change’s impact on the age-old rhythms of U.S. forests.

It might also raise questions about Parker and members of his team, who say they enjoyed almost every minute of it.

Directional Signage and Maps in San Francisco

Friday, April 24th, 2009

Here are several pictures taken at the new California Academy of Sciences in San Francisco and at SFO airport last week. The museum’s exhibits and aquarium make extensive use of maps and directional signage. They even feature an lenticular foil showing before and after glacier loss. The California Beef Council map was seen at the Fry’s parking lot in San Jose. The bathroom signage is from the SFO airport where they have both an in and an out for the restrooms :)

Melting Snow Prompts Border Change (The Independent)

Wednesday, April 1st, 2009

[Editor's note: No, this is not an April Fools joke ;) I often get asked, "Hasn't everything been mapped yet?". Well, some things always need remapping (and this begs the question as to why don't movie goers boycott theaters for showing the same the same Hollywood plots year after year, but whatever). The zones affected between Switzerland and Italy include the Matterhorn. Thanks Laris and Todd!]

Melting snow prompts border change between Switzerland and Italy
By Peter Popham in Rome
Tuesday, 24 March 2009

Global warming is dissolving the Alpine glaciers so rapidly that Italy and Switzerland have decided they must re-draw their national borders to take account of the new realities.

The border has been fixed since 1861, when Italy became a unified state. But for the past century the surface area of the “cryosphere”, the zone of glaciers, permanent snow cover and permafrost, has been shrinking steadily, with dramatic acceleration in the past five years. This is the area over which the national frontier passes and the two countries have now agreed to have their experts sit down together and hash out where it ought to run now.

Daniel Gutknecht, responsible for the co-ordination of national borders at Switzerland’s Office of Topography, said “the border is moving because of the warmer climate”, among other reasons.

Geography Is For Real: Oil Costs Up (Sundry)

Sunday, August 3rd, 2008

Omnibus of a weeks’ newspaper coverage (reprints):

Are Oil Costs Creating a ‘Made Here’ Movement?
NY Times’ Andrew C. Revkin on August 2, 2008

Shipping Costs Start to Crimp Globalization
NY Times’ Larry Rohter on August 3, 2008

Larry Rohter, who recently returned to the United States after many years covering Brazil, has a fascinating story in the Sunday paper examining how high oil prices may be blunting the globalization of manufacturing. Concerns over carbon dioxide emissions may be playing a role, as well. He starts out with an anecdote about Tesla Motors, which planned to build its batteries in Thailand, assemble most of the components of its electric sports cars in Britain, and then sell them in the United States.

But high shipping costs have changed that company’s plans, and those of many others, Larry writes. Here’s the “nut graf”:

Cheap oil, the lubricant of quick, inexpensive transportation links across the world, may not return anytime soon, upsetting the logic of diffuse global supply chains that treat geography as a footnote in the pursuit of lower wages. Rising concern about global warming, the reaction against lost jobs in rich countries, worries about food safety and security, and the collapse of world trade talks in Geneva last week also signal that political and environmental concerns may make the calculus of globalization far more complex.

Maybe the world is not as flat, or small, as it once seemed. The breakdown of trade talks also implies more countries are thinking local. I’m not sure this bodes well for the global thinking, and interaction, that’d have to take place if the world were to get serious about curbing the growth of greenhouse gas emissions. What’s your take?
