POTD – Dreaming of our next Arizona vacation

A story of one of my all-time favorite photos, related to an upcoming vacation. We LOVE Arizona. The diversity of landscapes, the scenery, the wildlife…it’s just such a treat, and so different than what we have in our part of South Dakota.  We first went about 20 years ago and have been back many times since.  However, it’s been a few years!  We decided that we’d take a week-long vacation and head down to Tucson this winter.

From a birding perspective, the Tucson area (where we usually go) is birding nirvana for me, particularly when we go down to Madera Canyon and some of the other famed birding spots in the area. Winter is still good for birding, but not nearly as good as the spring and summer (HOT!!!!) months. But despite what birds we may find, there’s always the scenery.

If it weren’t for the oppressive heat in summer, if I had the choice of anywhere to live in the US, it would be in the Sonoran desert habitat of Arizona. My first time there, I was shocked not only by the beauty, but the amount of LIFE that you find there. Given the heat and aridity, I expected a place that was tough for live to thrive, but whenever we go, it seems full of birds, insects, reptiles, and other life.  The backbone of the ecoystem, the “big daddy” from a vegetation standpoint, are the giant saguaro cactus. So many species depend upon them, not only for cover and nesting cavities, but for food.  It’s really cool being there in May when the saguaro are blooming, and seeing how many critters utilize the big blooms.

The place we stayed many times is now sadly closed…”Hacienda del Desierto”, a former B&B that not only had wonderful hosts, but a massive acreage with their own Sonoran desert habitat. Many a morning on vacation I’d wake before dawn and roam their lands, running into critters including coyotes, javelina, birds, snakes, and even bobcat.  Right outside the Hacienda is one of the largest saguaro cactus you’ll ever see, a saguaro full of character, with all the nesting holes from the birds that have used it over the years. Elf Owls will often nest in this cactus, as will Gila Woodpeckers, Gilded Flickers, and other birds.

On one of these mornings at the B&B, I awoke just before dawn to a gorgeous sky full of wonderful, scattered clouds. As I walked out by the big saguaro, I thought I’d try something unique for me…a photo that wasn’t a bird! I wanted something that captured not only the grandeur of that saguaro, but the wonderful early morning sky.  I put on my (rarely used) wide-angle lens, and tried to get a shot that captured both the sky and the saguaro. Not happy with what I was getting, I decided to try something different. I laid down on the ground next to the saguaro, and shot straight up the cactus towards the sky.

I absolutely love the resultant shot.  I love it so much, I made a big 36″ tall print on canvas that adorns my office wall at work.  I paid the price for this photo!  I learned that even if you don’t see them, the Sonoran desert ground is LITTERED with cactus thorns of all shapes and sizes! After taking the photo, I returned to my room, and spent some time with my wife, who graciously removed the thorns from my back, and the back of my legs and arms.  A price, but oh so worth it for one of my favorite photos of all time.

Spring Has Sprung! It’s February 22nd!

Snow Goose Migration

Snow Geese migrating through the area. We started seeing Snow Geese in small numbers over 10 days ago. Starting in the latter half of last week, huge flocks started moving through. Just a few days after Valentine’s Day, when normal HIGH temperatures should be around freezing, and we’ve got a major migration going on. That’s not the only sign of an early spring…or of global warming.

Ignore for a moment the forecast.  We’re supposed to get hammered with snow tomorrow, with a full-fledged blizzard watch.  We’re likely to get a foot, and possibly more, over a 24 hour period starting tomorrow.  It’s not supposed to get very cold though, with high temperatures of close to 30…very close to “normal” for this time of year.  Disregarding what’s likely to happen tomorrow though, it’s been anything BUT a “normal” winter in South Dakota.

Right before Valentine’s Day, people started noticing small groups of geese passing overhead.  We can get truly massive flocks of Snow Geese that move through in the spring, and we also get large flocks of migrating Canada Geese and Greater White-fronted Geese.  What’s NOT normal is to start seeing the goose migration in mid-February!  With incredibly warm weather in February (It was over 70 degrees in Sioux Falls yesterday, and nearly 65 today, more than 30 degrees above normal!!), the trickle of migrating geese has become a torrent, with truly massive flocks of birds moving through the area.  Normally at this time of year, I’m hunkered down in the cold, with my local birding restricted to the few Dark-eyed Juncos, Downy Woodpeckers, or American Goldfinches that might visit my feeders.  This year I’m already enjoying the sights and sounds of thousands upon thousands of VERY early migrants.

The warm weather and the migrating geese aren’t the only signs of an incredibly early “spring”.  Given that my livelihood is based on the use of satellite imagery for mapping, monitoring, and ultimately predicting what’s going to happen on the earth’s surface, I follow a lot of other similar work, including data provided by the National Phenology Network.  “Phenology” is “the study of cyclic and seasonal phenomenon”, and the National Phenology Network examines plant and animal phenology and how it relates to the environment.  From a vegetation standpoint, we can  use satellite imagery to assess the phenology of growing vegetation, tracking the timing of spring “green-up”, peak vegetation activity in the summer, and the senescence/browning of vegetation in the fall.

The National Phenology Network produces a data product called the “Spring Leaf Index Anomaly”.  The measure compares satellite-based measurements of spring “green-up” of vegetation compared to the historical green-up across the United States. The latest update was a map of conditions released today, as shown here:

National Phenology Network - Spring Leaf Index Anomaly

The “Spring Leaf Index Anomaly” released today. Vegetation is already greening up as far north as Kansas City, a rate that is over 3 weeks ahead of when things normally start to green up. It’s such an anomalous, warm late winter so far that the legend is going to need some revising!!

We’re SO early in terms of vegetation green-up that we’re literally off the scale!  The legend for the Spring Leaf Index Anomaly shows how early or late spring green up is compared to historical, but only goes out to a 20-day departure from normal.  We are almost a full MONTH ahead of schedule for many parts of the U.S.

Warm weather, migrating geese, vegetation green-up from satellite imagery…it doesn’t stop there!  Daffodils are coming up around Sioux Falls!  In FEBRUARY!  Talking with colleagues from the east coast, daffodils and tulips started coming up a few weeks ago already!  We’ve still got plenty of porous, honeycombed ice on many of the lakes around here, but there’s quite a bit of open water, particularly with all the rivers and streams now unfrozen.

I’m still baffled how any rational human being can choose not to believe that climate change is occurring.  Even for the right-wing nut jobs who have long denounced climate change as some kind of incredibly elaborate, world-wide hoax that evidently involves all scientists on the planet, there’s been increased recognition that something is happening.  Well…duh!! Those same climate-change deniers have increasingly accepted that climate change is occurring, but refuse to believe that human beings that are the cause.

As a scientist, at this stage…frankly I don’t CARE if people believe we’re the cause.  The ship has already sailed…we’re already FAR down the path to severe climate change, given that we’re now over 400 ppm of carbon dioxide in the atmosphere.  There’s just no concerted, global, political, social, or MORAL will to make the sacrifices necessary to slow down climate change, so at this stage…SCREW the cause of climate change.  It’s HERE.  It’s HAPPENING.

If I could say one thing to the politicians who don’t want to acknowledge our role in changing the climate…AT LEAST SUPPORT ACTIVITIES THAT MONITOR CLIMATE CHANGE, and HELP US TO ADAPT TO WHAT’S COMING.  REGARDLESS of what you think is causing climate change, CLEARLY IT IS HERE.  The environment around is, the creatures within that environment, are necessarily adapting to the rapidly changing conditions.

The million dollar question is now if we can do the same.
