Wildlife refuge photos, early January 2016

January 5, 2016

National Wildlife Refuges. Four days ago, most people were very fuzzy on what they are, except for members of Ducks Unlimited, and conservationists.

Here are a few Tweets to help the rest along.

Moose at the National Elk Refuge, outside Jackson Hole, Wyoming:

Wisdom is a 64-year old albatross who remarkably returns to the Midway National Wildlife Refuge every year, and has raised chicks most of those years. Midway NWR is northwest of Hawaii:

Sparky the lightning catching bull bison, at the Midwest NWR:

Every Kid in a Park shares a photo of an unnamed wild area (threw it in just for the heck of it):

Yellow-rumped warbler at the Sacramento NWR:

USFWS workers conduct a controlled burn at the Okefenokee NWR in Florida:

Hamden Slough NWR, Minnesota, is 26 years old today, January 5:

Great blue heron at Sacramento NWR:

Pied-billed grebe at Sacramento NWR:

Conservatives keep misattributing a famous quote to Thomas Paine, but it was Ed Abbey who said it. Rumor is you can find Abbey at the Caza Prieta NWR in Arizona:

Buenos Aires NWR, Arizona:

Wichita Mountains NWR, Oklahoma:

Bosque del Apache NWR, New Mexico (near Las Vegas, New Mexico, home of the first Owl Cafe and the wonderful Owl Burger):

Lake Klamath NWR in Oregon, critical habitat for ducks along the Pacific flyway:

Loxahatchee NWR:

“Conservatives” want to sell these lands off, or drill for oil or gas, or mine for minerals, on many of these lands. Will these places be preserved for your great grandchildren and America’s future?


January 5, 1502: A deal is a deal, with Columbus’s most prized possession

January 5, 2016

Who can you trust, if not the king and queen?

Columbus feared that King Ferdinand and Queen Isabella would not honor pledges they had made to him as recompense and honor for his great work of discovery on their behalf.  Before his final voyage, he assembled a legal document showing those promises made to him, and his work for Spain.

This illustrates, once again, the human dimension of the great drama of the age of exploration, of Columbus’s stumbling on to the America’s in his efforts to get to China.

The Library of Congress and the History Channel team up again to show off these grand snippets of history:

On January 5, 1502, prior to his fourth and final voyage to America, Columbus gathered several judges and notaries in his home in Seville. The purpose? To have them authorize copies of his archival collection of original documents through which Isabel and Fernando had granted titles, revenues, powers and privileges to Columbus and his descendants. These 36 documents are popularly called “Columbus’ Book of Privileges.” Four copies of his “Book” existed in 1502, three written on vellum and one on paper. The Library’s copy, one of the three on vellum, has a unique paper copy of the Papal Bull Dudum siquidem of September 26, 1493, which extended the Spanish claim for future explorations.

513 years ago today.

Parts of Christopher Columbus’s journals parked for a visit to Dallas, through January 3, at the Meadows Museum on the campus of Southern Methodist University. When we visited, the exhibits were not crowded. Who cares about ancient history today? Not enough.

Geography from space: Nile at night, a river of light

September 25, 2015

Geography teachers love the Nile Delta because it so well epitomizes what a river delta is — clear demonstration of the delta form, in real photos.

From the International Space Station, the model gets ramped up a bit:

The Nile becomes a river of light, showing the advance of electrified human settlement along the banks, and providing stark contrast to the unlighted desert on either side of the river.

What other cities, landmarks, or geographical features can you identify in the photo?


Autumnal equinox, September 23, 2015

September 23, 2015

You can only get this shot on two days each year.

I was sad to discover most of my U.S. history students (juniors) didn’t know what an equinox is. So the autumnal equinox always offers a teaching moment that ticks off the teacher raters.

Summer 2015 ended at 4:15 a.m., September 23.

This is what an equinox looks like, from 2013 photos.

But only twice a year, during an Equinox, can it capture an image like this one, showing an entire hemisphere bathed in sunlight. At an Equinox, the Earth’s axis of rotation is not tilted toward or away from the Sun, so the solar illumination can extend to both the planet’s poles. Of course, this Elektro-L picture was recorded on September 22nd [2013], at the northern hemisphere’s autumnal equinox. For a moment on that date, the Sun was behind the geostationary satellite and a telltale glint of reflected sunlight is seen crossing the equator, at the location on the planet with satellite and sun directly overhead (5MB animated gif).

Wait. Animated .gif?  Cool!

The autumnal equinox is at 8:22 GMT or 4:22 am EDT on Wednesday. The two satellite images below from the European Meteosat show the sun angle on Earth from June 22 near the summer solstice and then today at the same time.  Notice the sun angle has changed dramatically, and the High Arctic is no longer seeing 24 hour daylight.

Below is today at the same time.

Milky Way over Argentina observatory

September 22, 2015

From NASA’s Astronomy Picture of the Day:

Milky Way over Bosque Alegre Station in Argentina Image Credit & Copyright: Sebastián D' Alessandro. To see the picture in its unadorned glory without the explanatory overlay, click on the image to get to NASA's APOD site.

Stars in the Southern Hemisphere differ a lot from what we see in the North, most famously with the Southern Cross (Crux, in the image above).

Glorious anyway; more glory to go around.

If you click over to the APOD site, you can also see this photo without the overlay, which is another whole world of wonderfulness.

APOD said:

Explanation: What are those streaks of light in the sky? First and foremost, the arching structure is the central band of our Milky Way galaxy. Visible in this galactic band are millions of distant stars mixed with numerous lanes of dark dust. Harder to discern is a nearly vertical beam of light rising from the horizon, just to the right of the image center. This beam is zodiacal light, sunlight scattered by dust in our Solar System that may be surprisingly prominent just after sunset or just before sunrise. In the foreground are several telescopes of the Bosque Alegre Astrophysical Station of the National University of Cordoba in Argentina. The station schedules weekend tours and conducts research into the nature of many astronomical objects including comets, active galaxies, and clusters of galaxies. The featured image was taken early this month.


Annals of Global Warming: Warm the oceans, raise the sea level

September 15, 2015

Svein T veitdal is one of those rare scientists who can explain why science observations are important in effects on people in just living their lives. A good man to listen to (you can follow his Twitter account: @tveitdal).

Recently he sent this notice:

Critics of the science of climate change and the work to slow or halt warming don’t like charts like that. Sea level is something measured by humans, worldwide, for a long time. That’s real data.

And it’s scary.

T veitdal’s Tweet was just a small part of a very large graphic from NASA, explaining the observations that tell us sea levels rise, how the observations are made, and what it means to you and me.

NASA infographic on sea level rise

NASA infographic on sea level rise: We know seas are rising and we know why. The urgent questions are by how much and how quickly. Available to download, this infographic covers the science behind sea level rise, who’s affected, how much melting ice is contributing, and what NASA is doing to help.

Yeah. “Your planet is changing. We’re on it.”

As Ban-ki Moon said the other day, there is no Planet B. We have only one Earth.

General science teachers, geology teachers, physics and chemistry teachers, history, geography and human geography teachers should see if someone at your school has a plotter and can print this thing out for you, poster size.


August 24, 79 C.E.: Vesuvius spoke, with thunder

August 24, 2015

Much as the GOP Caucus and other climate-change deniers, Roman officials in Pompeii and Herculaneum refused to be alarmed at the ground shaking, and obvious eruptions from Mount Vesuvius, on August 24, 79 C.E.

In the past week we have earthquakes in California, Nepal, British Columbia, and other places. The old Earth keeps rumbling.

Oddly, we now pay more attention to earthquakes than to other things that can cause greater, rolling disasters.

Santayana’s Ghost wonders if we ever learn from history.
