A good scientist, who also believes in global warming, explains the irrelevance of “extreme weather” to the climate change debate.

Yet [an increase in extreme weather] is not supported by science. “General statements about extremes are almost nowhere to be found in the literature but seem to abound in the popular media,” climate scientist Gavin Smith of the NASA Goddard Institute for Space Studies said last month. “It’s this popular perception that global warming means all extremes have to increase all the time, even though if anyone thinks about that for 10 seconds they realize that’s nonsense.”

The scientist writing this op-ed is Bjorn Lomborg. He gives a lot of details. Here’s just one:

Global warming, in general, will mean higher temperatures. This causes more heat waves — more extreme weather. But it also causes fewer cold waves — less extreme weather. Many more people die from excessive cold than excessive heat, so fewer people will die from cold and heat in the future. By mid-century, researchers estimated in 2006, that means about 1.4 million fewer deaths per year. In the continental United States, heat waves in the past decade exceeded the norm by 10 percent, but the number of cold waves fell 75 percent.

Moreover, global warming will mostly increase temperatures during winter, at night and in cold places, making temperature differences less extreme.

When will SpaceX launch the upgraded Falcon 9? We have competing news stories:

When will SpaceX launch the upgraded Falcon 9? We have competing news stories:

  • The Canadian Space Agency sent out a press release today saying Cassiope will launch on September 15 on its Falcon 9 rocket.
  • Elon Musk sent out a twitter report of yesterday’s static fire test, noting there were anomalies and that the launch date is still to be determined.

This is very puzzling. That the Canadian release was sent out today suggests that they have information we don’t have about the static fire test and thus knew they could announce the launch date. That Musk is more circumspect however suggests that the information the Canadians have is not correct.

Update: Stephen Clark at Spaceflight Now has more information. It appears the launch will not happen on Sunday, as SpaceX plans a second launchpad static test tomorrow to iron out the unexplained “anomalies” in yesterday’s static test.

It is now eight years since a major hurricane made landfall in the United States.

It is now eight years since a major hurricane made landfall in the United States.

[N]ot a single major hurricane, defined as a Category 3 storm or higher on the Saffir-Simpson scale —with minimum wind gusts of at least 111 mph (178 km/h) — has directly hit the United States in nearly eight years. That’s twice as long as any major hurricane landfall “drought” since 1915, and by far the longest on record since data began being collected prior to 1900. As of today (Sept. 12), it’s been 2,880 days since Hurricane Wilma, the last major hurricane to strike the United States, made landfall on Oct. 24, 2005.

And guess what? The reasons have nothing to do with global warming!

NASA has announced a press conference for later today about the Voyager spacecraft.

NASA has announced a press conference for later today about the Voyager spacecraft.

The rumors are that all the scientists involved with this data from this spacecraft now finally agree that Voyager has left the solar system. More to come.

The rumors were true: NASA has confirmed that Voyager 1 is out of the solar system and in interstellar space, and has been since last summer.

Astronomers have compiled the first detailed 3D map of the inner regions of the Milky Way.

Astronomers have compiled the first detailed 3D map of the inner regions of the Milky Way. More here.

They find a box/peanut shaped bulge with an elongated bar and a prominent X-structure, which had been hinted at in previous studies. This indicates that the Milky Way was originally a pure disk of stars, which then formed a thin bar, before buckling into the box/peanut shape seen today.

Despite the significant increase in the Arctic icecap’s size this winter, satellite data of the icecap’s actual volume and thickness suggest that the new ice was quite thin.

The uncertainty of science: Despite the significant increase in the size of the Arctic Ocean’s icecap this winter, satellite data of the icecap’s actual volume and thickness suggest that the new ice was quite thin.

Prof Andy Shepherd, from Leeds University, said: “Now that we have three years of data, we can see that some parts of the ice pack have thinned more rapidly than others. At the end of winter, the ice was thinner than usual. Although this summer’s extent will not get near its all-time satellite-era minimum set last year, the very thin winter floes going into the melt season could mean that the summer volume still gets very close to its record low,” he told BBC News.

It is not surprising that the ice was thin, considering that the icecap was recovering from a record low the year before. The scientific question, however, is whether the cap will thicken in the coming years or continue to thin out. That it has recovered somewhat in size might be a onetime jump as the decline continues, or it might be indicative of a new growing trend.

“The face of the sun is nearly blank.”

Today NOAA posted its monthly update of the solar cycle, and as I do every month, I am posting it here, with annotations.

Before we take a look at that, however, there is other climate news that is apropos. The Daily Mail in the UK put out an entertaining article on Saturday with the headline “And now it’s global COOLING! Record return of Arctic ice cap as it grows by 60% in a year.”

The article is entertaining because, after illustrating the ice-cap’s recovery this year, it then notes the 2007 prediction by global warming climate scientists that the Arctic Ocean would be “ice-free” by 2013. If this isn’t a good example of the dangers of crying wolf, I don’t know what is.

I should emphasize that the ice-cap recovery this year does not prove that global warming has ceased. A look at this graph from satellite data shows that even though the Arctic icecap has recovered, it is still remains small when compared to the past few decades. The increase this year might only be a blip, or it could be indicating a new trend. We won’t really know for another five years, if then.

The article is also entertaining because it outlines the confusion that is right now going on behind the scenes at the IPCC. The next IPCC report is scheduled to come out next month, but no one agrees with its conclusions because it apparently ignores or minimizes the approximately fifteen year pause in warming that has now been documented since the late-1990s.

In its draft report, the IPCC says it is ‘95 per cent confident’ that global warming has been caused by humans – up from 90 per cent in 2007. This claim is already hotly disputed. US climate expert Professor Judith Curry said last night: ‘In fact, the uncertainty is getting bigger. It’s now clear the models are way too sensitive to carbon dioxide. I cannot see any basis for the IPCC increasing its confidence level.’ [emphasis mine]

It appears that scientists and governments are demanding approximately 1500 changes to the IPCC draft, which suggests its release will be delayed significantly.

Meanwhile, the Sun continues its lackluster and weak solar maximum.

Astronomers submit a slew of proposals for using the partly crippled Kepler space telescope.

Astronomers submit a slew of proposals for using the partly crippled Kepler space telescope.

Ideas range from a survey of potentially hazardous near-Earth objects to a study of Jupiter-sized exoplanets in large orbits. Kepler scientists will sort through the proposals and decide by 1 November which ones, if any, to recommend to NASA headquarters for further review.

Sadly, none of these ideas excites me very much. The tragedy here is that we have this really good optical telescope above the atmosphere, and we can’t point it accurately enough to use it.

“The timing couldn’t be worse.”

The next IPCC report: “The timing couldn’t be worse.”

The author describes how the new report, due out in just a couple of months, is probably already obsolete because of a slew of new papers documenting the long 10 to 15 year pause in global warming that was not predicted by any of the climate models used by the IPCC.

This quote I think sums things up nicely, however:

Due to a ‘combination of errors’, the models have overestimated warming by 100% over the past 20 years and by 400% over the past 15 years.

No Atlantic hurricanes in August for the first time in eleven years.

More extreme weather, eh? There were no Atlantic hurricanes in August this year, for the first time in eleven years.

As I’ve noted repeatedly, there is no evidence yet of an increase of extreme weather events as predicted by global warming advocates. In fact, some recent data suggests a decline, though I personally wouldn’t take that seriously either.

So, when Al Gore or Barack Obama or Dianne Feinstein starts running around like Chicken Little, claiming the sky is about to fall, remember these facts.

Physicists have managed to create and confirm, for a brief moment, the existence of the 115th element of the periodic table.

Physicists have managed to create and confirm, for a brief moment, the existence of the 115th element of the periodic table.

In experiments in Dubna, Russia about 10 years ago, researchers reported that they created atoms with 115 protons. Their measurements have now been confirmed in experiments at the GSI Helmholtz Centre for Heavy Ion Research in Germany.

To make ununpentium [the new element’s temporary name] in the new study, a group of researchers shot a super-fast beam of calcium (which has 20 protons) at a thin film of americium, the element with 95 protons. When these atomic nuclei collided, some fused together to create short-lived atoms with 115 protons. “We observed 30 in our three-week-long experiment,” study researcher Dirk Rudolph, a professor of atomic physics at Lund University in Sweden, said in an email. Rudolph added that the Russian team had detected 37 atoms of element 115 in their earlier experiments.

Scientists using data from India’s Chandrayaan-1 space probe have detected new evidence of water inside one crater.

More water on the Moon: Scientists using data from India’s Chandrayaan-1 space probe have detected new evidence of water inside one lunar crater.

What makes this detection important is that this particular water was not placed there by the solar wind or asteroids. Its chemistry suggests it seeped upward from deep within the Moon’s interior.
