Madeline in the snow

Madeline was meowing and meowing to go outside, so I said okay and let her out. She stepped awkwardly through the crusty snow on the porch for a few minutes before deciding to come back inside.

Yay, gay marriage in D.C.!

I've been following this for a while, and I'm not surprised it passed a council vote. The D.C. Council is on the side of justice and equality for all! There is a 30 day window in which U.S. Congress reviews the legislation and has the option of blocking it, but most experts do not think it's likely that this bill will be shot down.

HOWEVER (there's always a "however" when in comes to gay marriage in the U.S.) the Catholic Archdiocese of Washington has threatened to cut their social services programs - homeless shelters, soup kitchens, etc. - if this bill passes. Seriously. Can you believe it? The Archbishop is using poor people as political pawns. The WWJD fad has mostly passed, but I urge Archbishop Wuerl and all like-minded Catholics to ask what would Jesus do in this situation...would he really stop his ministry if the state passed a law condoning something he found unethical (not that I believe Jesus ever thought homosexuality is unethical)? Not my Jesus! This is ridiculous. Today Catholic charities - all charities - are needed more than ever. I admire and respect such charities and hope that the D.C. Catholics will not follow through on their threats.

Pomegranate

I've had pomegranate but I've never prepared one before. According to the December issue of Runners World pomegranates are in season Nov-Jan. They recommend slicing the pomegranate and rubbing the pieces in a bowl of water to remove the juicy, corn-kernel-like seeds. Don't they look festive and Christmasy?

An argument to stop "going green"

It makes a lot of sense, actually. But one important point that Mike Tidwell left out of his opinion article is that regulating land use change is nearly as significant as halting fossil fuel burning when it comes to reducing our carbon emissions and achieving that 350 ppm target.

Betting on Copenhagen

Olivia Judson is one of my favorite science writers. In addition to authoring "Dr. Tatiana's Sex Advice to All Creation", she is a regular contributor to the NY Times. You must check out her recent blog post called "Betting on Copenhagen". She really has a knack for digesting a complex issue like climate change into an entertaining, easy-to-understand, yet completely accurate (check her Notes section) format.

Blog Action Day: Climate Change

Better late than never. October 15 was Blog Action Day, a global effort to get the blogosphere to collectively highlight a single issue. This year's theme is "climate change", so I thought I'd kill two birds with one stone and blog about my trip to Austria with special emphasis on why I went there: to attend the International School on Alpine Ecology and Global Change. High latitude and high elevation regions are experiencing more rapid and extreme climate change compared to other regions, and these ecosystems are also among the most sensitive to such perturbations. I don't have my notes with me, but I think the numbers were something like 1.6 C/year warming rate in alpine regions compared to 0.6 C/year warming rate as a global average. I'm sure most people are familiar with before and after glacier photos such as these. I've seen plenty of such photos, too, but the experience of actually hiking over glacial-free moraines that were created only a few decades ago and still being kilometers away from what was left of the Rotmoos Glacier was quite unique. There is an absolutely excellent group of scientists at the University of Innsbruck who study this glacier and the ecosystems around it.

I am standing approximately where the glacier used to be only 30-40 years ago. The Rotmoos Glacier is retreating at a rate of about 30-40 meters per year, with a retreat of as much as 70 m/yr during especially warm years. 70 m !!! That's crazy. In fact, while we were there we watched as a huge chunk of the glacier edge broke off in front of our eyes.

Here's a picture of the 1920 terminal moraine (that small "bump" in the valley, about halfway down the photo):



and here's one of the 1853 moraine (again, the "bump" in the landscape):



The Rotmoos is only one of the countless glaciers all over the globe that are quickly disappearing. Most of us find it quite alarming, but some people may ask "so what?" I mean, yeah, how many of us actually ever visit a glacier? Only us geeky scientists and outdoor enthusiasts. But how many of us actually depend on glaciers? Billions of us. No shit. Glaciers provide water for much of the world, including populous countries like China and India. When the climate warms and glaciers melt, people turn to other water sources, like groundwater, an ultimately non-renewable source in most regions when compared to the rate it is extracted. So yeah, glaciers are pretty important, such that we've even figured out how to tell kids about this.

Here's yet another indication of climate change in alpine regions:



This fake lake was built at 2000 m elevation for snow-making. I can't believe that snow-making is needed at 2000 m elevation! Climate change is influencing (note present tense) a variety of alpine ecosystem services, including ski tourism, an economically important industry in many regions. Another alpine ecosystem service being anthropogenically affected directly by land use alteration and indirectly by climate change is the native, stabilizing vegetation community. What do I mean by "stabilizing"? Many of the herbaceous and shrub vegetation holds the soil in place and prevents or at least mitigates the impacts of mudslides/ landslides, which drastically affect communities who live in alpine valleys. This webpage seems to sum up nicely a lot of things that we learned in this course (though I can't verify the authors' credentials).

Anyway, it was a great course and a great trip, and I hope I gave you some food for thought! See the rest of my pictures from Austria here.

It's the orange crayons!

Oh, how I want to be 5 years old again, coloring with a new box of crayons!
