Junk science: This week NOAA government scientists published a paper claiming that the upcoming increase in rocket launches worldwide is a threat to the ozone layer and will also — my heart be still — promote climate change!
The study found that a tenfold increase in the amount of soot injected into the stratosphere every year would after 50 years lead to an annual temperature increase in that layer of 1 to 4 degrees Fahrenheit (0.5 to 2 degrees Celsius). The stratosphere is the layer of the atmosphere just above the lowest troposphere. The study found that the projected warming would slow down subtropical jet streams, bands of strong wind circling the planet at the lower edge of the stratosphere that influence the African and Indian summer monsoons.
Warmer temperatures in the stratosphere would also degrade the protective ozone layer, which blocks harmful ultraviolet radiation from the sun from reaching the planet’s surface.
The paper’s abstract also said this:
We show that the rocket black carbon increases stratospheric temperatures and changes the global circulation, both of which cause a reduction in the total ozone column, mainly in the northern high latitudes. Comparing the amplitude of the atmospheric response using different emission rates provides insight into stratospheric adjustment and feedback mechanisms. Our results show that the stratosphere is sensitive to relatively modest black carbon injections.
This is garbage science, and I wouldn’t bother posting a link to it if other news sources weren’t promoting it. These predictions — based on a very simple computer model — are nothing more than guesses, and are apparently designed to both attack the growing space industry as well as garner funding for more such junk science, as illustrated by this quote from the NOAA press release:
“We need to learn more about the potential impact of hydrocarbon-burning engines on the stratosphere and on the climate at the surface of the Earth,” said lead author Christopher Maloney, a CIRES research scientist working in NOAA’s Chemical Sciences Laboratory. “With further research, we should be able to better understand the relative impacts of different rocket types on climate and ozone.”
For almost a half century climate scientists — many working for government agencies like NASA and NOAA — have been publishing junk papers like this, predicting climate doom in only a few decades unless we do as they say, while funneling boatloads of cash into their pockets. Almost none of those predictions have turned out to be correct.
This report is equally suspect, especially because it touts the false statistic that “launch rates have tripled in recent decades.” The number of launches has not tripled from its long-term average since Sputnik. The only way you can get manufacture that fake statistic is if you compare last year’s total (134) with the launch numbers from the early 1960s, before the space race had even begun. And while the launch numbers are likely to rise dramatically in the coming years, the numbers will still be infinitesimal compared to other industries. Going from 50-100 launches to 200-500 launches is hardly the end of the world.
It really is far past time for the press and the general public to stop listening to these fake papers.
