Comet ISON caught on video!

Comet ISON appears to be a new comet. This bundle of icy dirty icy stuff was tugged by subtle gravitational forces out of the Ort Cloud, which is really really far away, and is now falling towards the sun. It will pass within view of us Earthlings later this year on its way towards the sun, and again, after it has swung around the sun, possibly displaying a spectacular tail, as new comets seem to do. Or, it could become vaporized during its first orbit. No one knows yet. Since ISON’s maximum visibility will be around Christmas, there will be all sorts of annoying references to Bible stories, and it is even possible that crazy cults will emerge and there will be people hiding in caves where they will do awful things to themselves in the belief that they can hitch a ride on the comet and get out of here. Let us hope not.

Anyway, NASA’s Deep Impact spaceship has videoed the comet as it moves along against a backdrop of stars and such. The video looks to me like the opening sequence in a hokey 1950s Science Fiction film, where this is the meteor carrying The Blob or something about to crash into the wilderness a few miles outside of town but dangerously close to Lover Lookout where it will be discovered by the captain of the football team and his lovely date who is also the daughter of the town sheriff. See if you agree:

You can read the background for this video and other stuff about ISON here, in the NASA press release.

Annual Amount of Carbon Released Into Atmosphere

Here are two graphs that show the amount of carbon released into the atmosphere, mainly as CO2 and mainly form the burning of fossil fuels, per year, from various sources for a long span of time. Both graphs are based on the same data set. the first graph was created by the Carbon Dioxide Information Analysis Center and shows the breakdown between different sources of carbon. The second graph, which I made, simply shows the total, and over a shorter time span to make it easier to use for other purposes.

Minnesota Moose

Minnesota has two populations of moose, one in the northwestern part of the state, one in the northeastern part of the state. Both are in decline. The decline seems to be mainly due to disease, which in turn, seems to be exacerbated by the occurrence of shorter, warmer winters and longer summers.

Today, the Minnesota DNR is announcing an indefinite halt to the annual moose hunt, because the latest surveys show that the population is in very serious decline. From a brief preliminary report in the Star Tribune:

Based on the aerial survey conducted in January, the new population estimate is 2,760 animals, down from 4,230 in 2012. The population estimate was as high as 8,840 as recently as 2006. At the current rate of decline, it could be gone from the state in 20 years, wildlife officials say.

I find it somewhat annoying that the state Department of Natural Resources still refuses to make the direct link between climate change and moose decline. They seem to be still under the thumb of erstwhile Republican administrations and couch their language accordingly. They need to stop doing that.

This is a developing story and I’ll have more on it in the future. In the mean time, here is an extended excerpt from a post I wrote a while back on the moose: Continue reading Minnesota Moose

How much can the sea level go up with global warming and how fast will it happen?

According to some estimates, if sea levels rose one meter, Boston would lose 3% of it’s land surface, Washington DC a mere 1%. Tampa and Miami would lose 18% and 15% respectively. New Orleans would lose 91%.

A six meter rise would result in much larger losses. Norfolk, Virginia and Miami Florida would be essentially gone.

These estimates use the assumption that the sea level rises in those areas vertically, and the corresponding topographical level in the coastal city becomes the shoreline. They don’t account for the fact that the ocean does not work that way. (see Sea Level Rise…Extreme History, Uncertain Future.)The shore of the ocean normally consists of a relatively flat zone covered by sea (perhaps exposed ~2 times a day at low tide), a steeper zone where the sea intercepts the land (and generally goes up and down a certain amount with the tides) which was carved out by erosion, then inland, whatever topography would have been present prior to the incursion of the sea. The original shorline first contacted by the sea is gone, and the strandline has moved, or transgressed (that’s the term we use), some distance across the landscape. In a place like Miami, the sea may transgress many miles across relatively easily eroded sediment. In a place like Boston, filled land (which makes up a huge amount of that city’s land surface) might be easily eroded away, glacial sediments that make up much of the city’s substrate would erode fairly quickly. Rock conglomerates that make up much of the southern part of the city would erode slowly while weathered argilite underneath Cambridge would be eroded away quickly. The North Shore communities, sitting on hard rhyolite, would make nice islands for a long time. In other words, it would be complicated.

Santa Cruz, Solomon Island Earthquake and Tsunami UPDATE: several villages destroyed

There was an 8.0 magnitude earthquake a few minutes ago in the vicinity of Santa Cruz Islands, in the South Pacific, and it is now confirmed that this generated a potentially severe tsunami that by now would have hit nearby islands. But, no one has reports from the scene to confirm or elaborate on this. That is a very large earthquake, and apparently shallow.

Info here.

Of special note, in all caps, because that’s how meteorologists roll:

SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE
BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER AND
COULD ALSO BE A THREAT TO MORE DISTANT COASTS. AUTHORITIES SHOULD
TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS
CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE
EXTENT AND SEVERITY OF THE THREAT

UPDATE

Not much info yet, but I’m sure there will be plenty of info tomorrow.

The Kiss

Valentine’s Day is coming up, so it is time to think about kissing. Pursuant to this, Sheril Kirshenbaum, author of “The Science of Kissing,” has made the Kindle version of her excellent book available at a discounted price through February 18th. The book is here: The Science of Kissing: What Our Lips Are Telling Us.

I went out with a friend. We were both between relationships, and we both knew somehow that this was a date though it was never called a date. And we had a perfectly good time: Good food, good conversation, good drinks. She drove.

When it came time to go home, she drove me to the urban neighborhood I lived in and parked on the street near my house. As we were saying our good-byes, she enigmatically unhooked her seat belt. I wondered why. Then, I discovered that she wanted the freedom of movement to lean across the console and give me a kiss. It was a good kiss. It was actually a series of good kisses, and it went on for a while.

And suddenly, there was a loud rapping on the window of the car. We stopped kissing and that’s when we noticed that we had steamed up the windows a bit. So I cracked the window on which the rapping had occurred and there was a policeman staring in with his flashlight.

The Asteroid That Is Coming Really Close To Earth

In February, Asteroid 2012 DA 14 will come so close to earth that it will be nearer to our planet than many satellites are. This asteroid, which really should get a new name, is about half the size of a football field. Its orbit is similar to that of the Earth itself, in size and shape, but at an angle to the Earth’s plane, so it’s like the asteroid and the earth are driving in circles on two oval tracks that intersect at two points but there is no red light.

Asteroid 2012 DA 14 was discovered with gear provided to an observatory with a grant from the Planetary Society. Which makes me want to join the Planetary Society.

This asteroid is not going to hit the earth now or during any of the next few decades, but eventually it may well do so. We need to keep an eye on it.

The closest approach will be on Feb 15th, when it will be a mere 27,330 kilometers from the surface of the earth. You would be able to see it with binoculars or a telescope. You’ll be able to spot it, conditions and optics permitting, in Europe, Asia and Africa.

(For reference, the International Space Station skims at about 350 kilometers; a geostationary orbit is 35,786 kilometers.)

The following video from the Interplanetary Society has all the details:

Climate Change is Real Despite Fox News

Media Matters takes Fox News to Task. Watch the reasonable person talk, then watch the Republican climate science denialist lie:

Here is a graph from Media Matters that you should post on your Facebook page and elsewhere:

Fox News and Climate Science Truth
From Media Matters: “The American Geophysical Union and several other scientific bodies including the National Academy of Sciences have acknowledged manmade climate change based on a strong and growing body of evidence.
Despite all of this, Fox News has continually and falsely claimed the consensus on climate change does not exist — yet another example of the network’s willful denial of facts. As MSNBC host Rachel Maddow put it after the 2012 presidential election, conservative media need to “pop the factual bubble” if they’re going to offer solutions to our problems rather than just wish them away.”

Spread the word!

Permafrost

As you know, the permafrost is melting due to global warming, and this is releasing greenhouse gasses which cause global warming. What you may not know is that we could not have had this conversation even a century ago because science has only recently recognized permafrost (it was not clearly defined and known of in the early 20th century). John McKay, an expert on hairy elephants and related things, has written up a description of what may be the first scientific description of permafrost, from a century or more prior to it’s incorporation into the scientific conversation as a reasonably well understood concept, by a botanist working a bit out of his field of expertise in 1806. Check out: An Early Description of Permafrost at Mammoth Tales.

Should secular organizations combine? Or should we try to look big?

In a recent Minnesota Atheists newsletter, oft-times president and general all round Atheist Leader August Berkshire wrote about the idea of Humanists of Minnesota and Minnesota Atheists combining. He notes that this may have been impossible in the pas when the philosophies of the two groups may have been quite different, but that now the philosophies are pretty much the same.

I have to say that I agree that as far as I can tell, Minnesota Atheists members and Humanists of Minnesota don’t seem to be at odds. I’ve seen members of the two groups in the same place many times and fights, or even mild arguments, never break out. Of course, this is Minnesota, so I may be missing something. Perhaps there are withering stern looks that I’m mising. but I don’t think so.

I also agree, and this is almost an aside with this observation by August:

“In my almost 30 years of atheist activism, it seems to me that virtually every schism, split, or separation in the freethought movement was based on personalities, ego, desire for power, or quibbles about a name – not on atheist/humanist philosophy. Can we rise above our differences for the greater good of coming together under the banner of a unified atheist and secular humanist organization? Should we? Or are there rational obstacles that are just too great to overcome?”

There seems to be nothing to stop Minnesota Atheists and Humanists of Minnesota from melding. They can call themselves MASH. Minnesota Atheists and Humanists of Minnesota.

But there is a down side that I want to point out because I think it is important. Numbers. Right now there are these two major groups and one or to other Minnesota based secular groups other than CASH. That is not very many different groups.

This problem occurred to me a few years ago when I was strolling among the UMN student group tables during “put your student groups out on tables” day on the Saint Paul campus. There as a table for each of at least 15 different clearly religious groups and probably a half dozen or more groups that were not explicitly religious but that were in fact religious just under the surface. And the tables out that day represented about a third, or less, of the actual groups out there. And then there was CASH, the one, single, lonely secular student group on campus. CASH has a couple of dozen members. If those members were distributed among six explicitly secular groups, they would have had six tables at that event.

More recently I attended the Anoka county Youth Gay Pride day fest, held on the banks of the Mississippi a few blocks down the street from my house. There were about 10 groups represented there that had to do with gay youth, and at least half of them were explicitly religious (i.e, they were churches). Had there been a table for Minnesota Atheists that would have been just one explicitly secular group. If there were five or six explicitly secular organization involved in human rights and social justice in Minnesota, there could have been a few of them at that event, giving the churches a run for the money.

Ditto for the May Day parade. Ditto for Pride Fest. Ditto for whatever-whatever. You get the point.

Perhaps instead of Minnesota Atheists and Humanists of Minnesota, merging, maybe they should each undergo mitosis!

OK, no one is going to go for that, but there are ways we can both combine and make ourselves larger. The two organizations can form the Minnesota Secular Coalition and also the Committee for Secular Approaches for Social Justice (CSASJ) and contribute a few people to each one to help run them. These organizations would provide a vehicle for outreach to communities that we are currently not reaching but that are reachable. Then, once or twice or even three times a years, at the right moments, we can put out a bit of extra effort and all of us can staff tables at some event or another.

And, then, instead of having a dozen churches and poor little us at one table, we can have a dozen churches and a half dozen us. Give them a run for the money I say!

In the mean time, we could perhaps consider a combined membership deal. For a bit extra, you can expand you membership in one group to include the other group(s) at the same time.

We can take a page out of the books of nature. A whole chapter, perhaps. The chapter on “looking bigger.” And sometimes, a little scary might be good too.

Updated with some corrections.
