A scientist describes the skeptic’s view of global warming.
And since good science should be founded of skepticism, he ends up describing the actual state of climate research, outlining all the uncertainties with great clarity and intelligence.
On Monday NOAA 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.
January was the most active month for sunspots this entire solar cycle, exceeding the predictions of the solar scientists, an event that has been quite rare during this generally weak solar maximum. In fact, the Sun was so active that for the first time, the second peak in a double-peaked solar maximum exceeded the first peak in sunspot activity.

Most Mars meteorites found on Earth may have been blasted here from a single impact on Mars around 3 million years ago.
This is a great scientific detective story. It has a lot of uncertainties, should definitely be taken with a grain of salt, but is nonetheless very convincing.
WISE’s survey of the sky in infrared has now shown that there is no large planet X orbiting beyond Pluto.
This recent study, which involved an examination of WISE data covering the entire sky in infrared light, found no object the size of Saturn or larger exists out to a distance of 10,000 astronomical units (au), and no object larger than Jupiter exists out to 26,000 au. One astronomical unit equals 93 million miles. Earth is 1 au, and Pluto about 40 au, from the sun. “The outer solar system probably does not contain a large gas giant planet, or a small, companion star,” said Kevin Luhman of the Center for Exoplanets and Habitable Worlds at Penn State University, University Park, Pa., author of a paper in the Astrophysical Journal describing the results.
The theory, popular among planetary scientists and journalists, is that this theorized distant planet would periodically disturb the orbits of comets in the Oort Cloud, sending them raining down on Earth and thus cause the periodic extinction events found in the paleontological record. It was a cute theory, but based on little data. Now we have the data, and no such planet exists.
The data has found a lot of previously unknown nearby stars and brown dwarfs, which is significant in that they are close and can be studied more easily.
From a Nobel Prize winner: “I think peer review is hindering science. In fact, I think it has become a completely corrupt system.”
Read the whole interview. The scientist outlines problems not only with peer review journals but with the whole structure of modern academic science, which to his mind would have prevented him from doing his Nobel Prize winning research had this system existed then.
In reporting on climate change, ABC and CBS have excluded all commentary from any skeptical scientists for literally years.
Neither CBS nor ABC have included a skeptical scientists in their news shows within the past 1,300 days, but both networks included alarmists within the past 160 days — CBS as recently as 22 days ago. When the networks did include other viewpoints, the experts were dismissed as “out of the scientific mainstream” or backed by “oil and coal companies.”
It is almost like these news organizations are closing their eyes and sticking their fingers in their ears and chanting, “La, la, la, la, la, la, la, la…” Not the kind of behavior you’d expect from a legitimate news organization.
Chicken Little report: Another rock will fly past the Earth today, killing no one.
The 33-foot-wide (10 meters) near-Earth asteroid 2014 EC will come within 34,550 miles (55,600 kilometers) of Earth’s surface this evening (March 6) — just 14 percent of the distance between our planet and the moon, which is about 239,000 miles (385,000 km) on average.
The key quote, however, is this:
Such back-to-back flybys are pretty special, though they can’t exactly be called rare events, [JPL scientist Don] Yeomans said. “For small asteroids, one would expect a flyby of the Earth, to within the moon’s distance, about every two weeks,” he said.
In other words, these flybys happen a lot, with no consequences.
Hubble photographs the break-up of an asteroid.
The ongoing discovery of more fragments makes it unlikely that the asteroid is disintegrating due to a collision with another asteroid, which would be instantaneous and violent in comparison to what has been observed. Some of the debris from such a high-velocity smash-up would also be expected to travel much faster than has been observed.
It is also unlikely that the asteroid is breaking apart due to the pressure of interior ices warming and vaporising. The object is too cold for ices to significantly sublimate, and it has presumably maintained its nearly 480-million-kilometre distance from the Sun for much of the age of the Solar System.
This leaves a scenario in which the asteroid is disintegrating due to a subtle effect of sunlight that causes the rotation rate to slowly increase over time. Eventually, its component pieces gently pull apart due to centrifugal force. The possibility of disruption by this phenomenon — known as the YORP effect — has been discussed by scientists for several years but, so far, never reliably observed.
A look at the President’s overall budget for science, which finds spending levels remain flat.
What makes this story significant is that the budget is really flat. Some agencies will get more money, others less, with the total spent about the same as the year before. They are not discussing, as had been typical in the past, the rate of increase in spending, where a reduction in that rate would be reported falsely as a “cut.”
Chicken Little report: A 100-foot diameter newly discovered asteroid will zip past the Earth inside the Moon’s orbit today at 4:07 pm Eastern.
The asteroid, dubbed 2014 DX 110, is about 100 feet in diameter and is set to come within 216,000 miles of Earth — a close shave by astronomical standards, considering our Moon orbits the Earth at a distance of about 238,900 miles.
While an object that size may not seem imposing, if it were to strike the Earth, it would release a devastating amount of energy greater than a nuclear weapon. The infamous asteroid that exploded over Tunguska, Siberia, on June 30, 1908, has been estimated to be about 30 meters to 60 meters — 100 feet to 200 feet — in diameter.
While it is true that the impact would be significant, this news report does the typical fear-mongering to make the story seem interesting. The problem, however, is that the detection of these fly-bys is becoming more frequent. The number of asteroids isn’t changing, but our ability to spot them is, and with more frequent discoveries comes more frequent news stories like this. I fear that such stories — fueled by press releases from various astronomy organizations — are going to begin to sound like a kid “crying wolf” to the general public. The threat from an asteroid impact is real, even if most asteroids miss us. Desensitizing the public to the threat is not a good thing.
One of the publishers who had published numerous fake peer-reviewed papers generated by a computer program has responded aggressively to fix the problem.
And by aggressive I mean positively. They have removed the fake papers and are reviewing everything they’ve published, with the help of the guy who exposed the fakes, to make sure there aren’t any other fakes not yet identified. They also say they are reviewing their procedures to figure out how this happened and to prevent it from happening again.
