Trump On Hairspray And Ozone

For at the very least 5 years, Donald Trump has been making false claims about hairspray and its impact on the ozone layer. Most lately, the doubtless Republican presidential nominee made feedback at a campaign rally in West Virginia:

– Trump stated “hairspray’s not like it used to be” as a result of chemicals in it that have an effect on the ozone layer have been banned. Many nations began phasing out the ozone-depleting substances in hairspray in the late 1980s, but these laws wouldn’t affect the quality of hairspray.
– He additionally said utilizing hairspray in his house, “which is all sealed,” would stop any ozone-depleting substances from escaping into the setting. However these chemicals would nonetheless make their method out, multiple experts instructed us.

Hairspray is made up of chemicals that make hair stiff and a propellant. Hairspray and many different aerosols used chlorofluorocarbons as propellants until many main nations began phasing out these chemicals after the signing of the Montreal Protocol in 1987. CFCs are potent ozone-depleting substances.

In the place of CFCs, many countries began using hydrochlorofluorocarbons and hydrofluorocarbons as propellants in aerosols. CFCs, HCFCs and HFCs are all potent greenhouse gases. But HCFCs are about 5 p.c to 10 percent as potent at depleting ozone as CFCs, while HFCs are usually not considered ozone-depleting substances. Although nonetheless utilized in other varieties, HCFCs have been phased out of aerosols within the United States in 1994, whereas HFCs nonetheless remain in use.

Trump has made claims about hairspray and the ozone layer a minimum of three times. Again in 2011 in Sydney, he implied the “eight-inch concrete floors” and “eight-inch concrete walls” of Trump Tower would stop hairspray from “destroying the ozone that’s four hundred miles up within the air.” In December 2015, at a campaign rally in Hilton Head Island, South Carolina, Trump additionally said he doesn’t “think something will get out” of his “sealed” house when he makes use of hairspray.

On May 5, 2016, at a campaign rally in Charleston, Trump implied that the laws on hairspray and coal mining are both unwarranted. On the rally, an official from the West Virginia Coal Association endorsed Trump and presented him with a hard hat. Trump tried on the hat, which prompted him to talk about his hair:

Trump, Could 5: Give me just a little spray. … You understand you’re not allowed to use hairspray anymore as a result of it impacts the ozone, you already know that, right I mentioned, you mean to inform me, cause you realize hairspray’s not prefer it used to be, it was real good. … In the present day you set the hairspray on, it’s good for 12 minutes, right. … So if I take hairspray and i spray it in my condominium, which is all sealed, you’re telling me that affects the ozone layer “Yes.” I say no approach of us. No way. No manner. That’s like a lot of the foundations and regulations you individuals have in the mines, right, it’s the same kind of stuff.

We contacted Trump’s marketing campaign for remark, nevertheless it hasn’t responded. If somebody does get again to us, we will replace this report accordingly. In the next sections, we’ll define how and why many countries agreed to phase out CFCs and substitute them with HCFCs and HFCs. We’ll also clarify why using hairspray inside wouldn’t stop ozone-depleting substances from reaching the atmosphere, as Trump claimed.

Nations Conform to Ban CFCs
First developed in the nineteen thirties underneath the commerce identify Freon, CFCs have been originally assumed to be secure for the setting. For that reason, CFCs made their way into a slew of family objects, from the coolants used in refrigerators to Styrofoam to aerosols like hairspray.

However in the 1970s researchers began questioning the security of these chemicals. Sherwood Rowland and Mario Molina, chemists on the University of California, Irvine at the time, found that CFCs had been able to depleting the ozone layer — winning the Nobel Prize in chemistry in 1995 for their work.

Then in the 1980s, scientists realized the ice particles in clouds over the Artic and Antarctic sped up the process Molina and Rowland initially found. Joseph Farman, a geophysicist on the British Antarctic Survey at the time, and researchers at NASA found a hole within the ozone layer above Antarctica that was roughly the scale of the United States.

How do CFCs deplete the ozone layer When a CFC molecule makes it to the stratosphere, photo voltaic radiation breaks it down, leaving behind a lone chlorine atom. The chlorine atom (Cl-) then reacts with an ozone molecule (O3), forsaking chlorine oxide (ClO) and oxygen (O2). In fact, Molina discovered that one chlorine atom could begin a series reaction that will result in the break up of around 100,000 ozone molecules.

First off, a CFC molecule doesn’t have four hundred miles to travel to succeed in the ozone layer, as Trump claimed in 2011. About ninety p.c of the ozone layer will be discovered between 6 to 10 miles above the earth’s surface, with the final 10 percent of the ozone layer extending as far as 30 miles above the floor. The stratosphere spans 5.5 to 30 miles above the earth’s floor.

Second, a depleted ozone layer is no small matter. A weakened ozone layer leads to an increase in ultraviolet radiation, which then brings about larger charges of pores and skin most cancers, cataracts and immune system problems in human populations. Increased UV radiation can even disrupt vital processes in plants and marine ecosystems.

The gravity of the problem prompted policymakers globally to signal the Montreal Protocol on Sept. 16, 1987. The settlement took effect on Jan. 1, 1989, and aimed to cut back the manufacturing and use of CFCs and different ozone-depleting substances. Nonetheless, the protocol has been amended six instances to take into consideration new scientific data and accelerate reductions in CFC and HCFC use. First signed by 46 countries, the protocol now has close to 200 signatories, including the United States.

In 2014, five international entities, together with the United Nations Environmental Program and NASA, printed a report that found actions “taken below the Montreal Protocol have led to decreases in the atmospheric abundance of controlled ozone-depleting substances (ODSs), and are enabling the return of the ozone layer towards 1980 ranges.” In fact, the report states the restoration of the ozone layer is “expected to occur before midcentury in midlatitudes and the Arctic, and somewhat later for the Antarctic ozone gap.”

In short, the propellants utilized in hairspray and other substances, CFCs specifically, have been banned. But the chemicals that make hair stiff weren’t topic to these laws. And CFCs have been banned for good purpose, regardless of Trump’s implication. Regulations carried out with the Montreal Protocol appear to be reversing the harm carried out to the ozone layer by CFCs in hairspray and different substances.

HFCs: For Higher and For Worse
Whereas hairspray not makes use of CFCs to propel the stiffening agent out of the can, it does use other chemicals as propellants which are potent greenhouse gases — namely HFCs.

In reality, the aforementioned 2014 report additionally discovered that “climate benefits of the Montreal Protocol could be significantly offset by projected emissions of HFCs used to replace” ozone-depleting substances.

At the moment HFC use (in hairspray and otherwise) “makes a small contribution” to greenhouse fuel emissions every year, clarify the report authors. However emissions from HFCs “are at the moment growing at a fee of about 7% per year” and growing demand may lead to HFC emissions reaching levels “nearly as high as the peak emission of CFCs” by 2050.

To be clear, CFCs are detrimental to the environment for no less than two reasons — they efficiently deplete ozone and they are potent greenhouse gases. That is, they contribute to global warming. HFCs, then again, don’t contribute to ozone depletion directly and efficiently like CFCs. But they still negatively influence the climate as greenhouse gases.

Margaret M. Hurwitz, an atmospheric scientist at NASA, and others discovered that HFCs could indirectly contribute to ozone depletion by modifying atmospheric temperatures and circulation.

Talking about her Oct. 22, 2015, research revealed in Geophysical Analysis Letters, Hurwitz informed Phys.org that her outcomes don’t suggest “HFCs are an existential threat to the ozone layer.” Nonetheless, “HFCs are, in reality, weak ozone-depleting substances,” she stated.

Hurwitz additionally defined to us by electronic mail that “[p]er unit mass, CFC-eleven causes about 400 times extra depletion of the protecting stratospheric ozone than the HFCs, while HCFC-22 causes eight occasions extra ozone depletion” than HFCs, for example. So the effect of HFCs on the ozone layer is considerably lower than that of CFCs, however it’s not zero.

As well as, Steve Montzka, a chemist at the Nationwide Oceanic and Atmospheric Administration, reiterated to us by e-mail, “It was never the stiffening agent in the spray that brought about the problem [with the ozone layer], it was the propellant.” We can’t comment on whether or not “hairspray’s not like it was,” as Trump claimed. However we will say changes in hairspray quality wouldn’t be a results of the alternative of CFCs with HFCs due to laws on the former.

Trump’s Not-So-Sealed Residence
We also requested Montzka whether using hairspray inside would prevent CFCs or HFCs from having an impact on the ozone layer in contrast with using it outside, as Trump claimed. “It makes absolutely no distinction!” he stated. Should you spray these chemicals “inside your hair extensions for black women hairstyles house or apartment, it would eventually make it exterior.”

“These gases cannot and aren’t confined to the kitchen or bedroom; they combine, diffuse, and are moved out of the native launch area to be transported throughout the lower atmosphere (over months) before they are transported upward to the stratosphere,” where the ozone layer is positioned, David Fahey, a physicist at NOAA, told us in an electronic mail.

This implies Trump’s hairspray use over the years has either straight (through CFCs) or indirectly (HFCs) contributed to the depletion of the ozone layer, albeit to a really small extent, despite what he has claimed.
