The uncertainty of knowledge

1:28 pm

NOAA this week posted its monthly update of the solar cycle, showing the sunspot activity for the Sun in January. As I do every month, I am posting it here, below the fold, with annotations.

Back in October the Sun’s sunspot activity had plummeted, following almost two years of very weak activity. At that time, I wrote, “It appears the solar maximum has ended. The only question now is how long and deep the upcoming solar minimum will be.”

Well, talk about foolish predictions. I should shake hands with Al Gore and James Hansen for making the mistake of announcing the future as if I know what will happen. The truth is that no one truly understands the Sun’s sunspot cycle.

In January the Sun continued the high sunspot activity of the previous three months, once again producing sunspots in numbers close to the actual predictions of the solar science community. And while all their predictions remain generally high when compared to the actual numbers, they can now feel reassured that the overall length and strength of this solar maximum is beginning to resemble the prediction of the solar scientists who thought this would be a weak maximum.

Mars Reconnaissance Orbiter spots a new crater on Mars.

Mars Reconnaissance Orbiter spots a new crater on Mars.

The scar appeared at some time between imaging of this location by the orbiter’s Context Camera in July 2010 and again in May 2012. Based on apparent changes between those before-and-after images at lower resolution, researchers used HiRISE to acquire this new image on Nov. 19, 2013. The impact that excavated this crater threw some material as far as 9.3 miles (15 kilometers).

Scientists claim that global warming will cause big waves that will exhaust fish!

I am not making this up: Scientists claim that global warming will cause big waves that will exhaust fish!

Anthony Watts does a nice job of tearing apart this truly bad research. As he says, “This is what passes for science now; it looks like a high school science fair project.” He also digs down to check their claim that global warming will cause bigger waves and finds it baseless.

But then, when did most global warming advocates ever care that much about actual data?

Congress hovers over commercial space like a vulture

9:34 am

We’re here to help you: A House subcommittee held hearings yesterday to consider updating the Commercial Space Launch Act that regulates the commercial space tourism industry.

Forgive me if I am pessimistic about anything Congress might do. So far, every time they have updated the law Congress has increased the regulatory regimen, making it harder and more expensive for these companies to get started. Consider these words from Donna Edwards (D-Maryland), the ranking Democrat on the subcommittee:

An analysis of the rotation of the peanut-shaped asteroid 25143 Itokawa suggests that its smaller end is actually far denser than its bigger end.

An analysis of the rotation of the peanut-shaped asteroid 25143 Itokawa suggests that its smaller end is actually far denser than its bigger end.

Previously, some researchers have proposed that Itokawa is actually two asteroids in contact with one another, a scenario strongly supported by the new results, the team contends. It’s not clear whether the odd configuration results from the merger of a two-asteroid system or merely clumps of material that fell back together after a larger asteroid was blasted apart by an immense collision.

The researchers also found that the asteroid’s rotation is actually increasing by 45 milliseconds per year.

Scientists have found that bumblebees have the capability of flying at altitudes higher than the top of Mount Everest.

Scientists have found that bumblebees have the capability of flying at altitudes higher than the top of Mount Everest.

In a study published today in Biology Letters, two zoologists, Michael Dillon, now at the University of Wyoming in Laramie, and Robert Dudley of the University of California, Berkeley, tested whether bumblebees’ vertical range was limited by aerodynamics and physiology. Working in the mountains of Sichuan, China, the duo caught five male bumblebees (Bombus impetuosus) foraging at 3,250 meters and placed them in a plexiglas chamber. Once the bees began to fly upwards, the pressure inside the chamber was reduced using a hand pump to simulate altitude increases in 500-meter intervals. All five bees could hover at air pressures equivalent to elevations of 7,400 meters; three could fly above 8,000 meters; and two got to above 9,000 meters.

If you read the entire article, you will notice that it completely ignores the false urban legend that bumblebees are aerodynamically unsound and shouldn’t be able to fly. Scientists have known for decades that it is false, but for some reason it keeps getting repeated.

A close look at the spending bills introduced in Congress shows that of the 70 members who sponsored the largest number of spending bills, 65 were Democrats, four were Republicans and one an independent.

A close look at the spending bills introduced in Congress shows that of the 70 members who sponsored the largest number of spending bills, 65 were Democrats, four were Republicans and one an independent.

This puts the lie to the claim that there is no difference between the two parties.

Will Piers Morgan apologize for spreading a racist hoax?

Will Piers Morgan apologize for spreading a racist hoax?

I doubt it, but even if he does apologize (as has happened a lot at NBC recently), he won’t really mean it. When you are a hate-filled bigot, working at a hate-filled television network, apologizes don’t mean you’ve mended your ways, only that you are looking for cover so you can spread more hate.

Note also that Deval Patrick, Democratic governor of Massachusetts, also joined Morgan in spreading this lie.

The 2014 Birthday Bleg

10:00 am

I really dislike doing this, but someone has to pay the bills, and this website is one way I do it. February 5 will be my sixty-first birthday. As I have done the past two years, I am posting a birthday bleg, requesting donations to help fund the existence of Behind the Black. If you like my webpage and want to support it in any way, please consider donating something. I would be grateful for anything you can give.. Some people have even subscribed, sending as little as $2 per month.

The tip jar can be found in the right column, below the search box.

A new report from the Congressional Budget Office has found that Obamacare will increase the deficit and slow the economy far more than originally predicted.

9:56 am

Finding out what’s in it: A new report from the Congressional Budget Office has found that Obamacare will increase the deficit and slow the economy far more than originally predicted.

The non-partisan agency’s report found that the healthcare law’s negative effects on the economy will be “substantially larger” than what it had previously anticipated. The CBO is now estimating that the law will reduce labor force compensation by 1 percent from 2017 to 2024, twice the reduction it previously had projected. This will decrease the number of full-time equivalent jobs in 2021 by 2.3 million, CBO said. It had previously estimated the decrease would be 800,000.

Aren’t you glad the Democrats shut the government down in October to prevent any delay or changes to their law?
