New York Is Phasing Out One of the Worst Climate Pollutants There Is

The Empire State is on a tear when it comes to tackling climate change. On Monday, as the mayor of New York City was calling on cities around the globe to divest their assets from fossil fuels, Governor Andrew Cuomo directed the state to phase out a potent greenhouse gas the Trump administration is ignoring.

From 2020-2024, New York will implement a phase-out of hydrofluorocarbons (HFCs), chemicals the cooling industry adopted widely in the 1990s as a replacement to chlorofluorocarbons, which were eating a terrifyingly large hole in the ozone layer. While HFCs don’t destroy ozone, they happen to be a serious climate pollutant with about 1,000 times the global warming potential of carbon dioxide. New York’s plan to phase them out is a step toward the state’s goal of reducing its total greenhouse gas emissions 40 percent by 2030.

“While the Trump administration denies climate change and rolls back efforts to protect our planet, New York is picking up the mantle of climate leadership and forging a path forward,” Governor Cuomo said in a statement.

To accomplish the phase-out—which would affect new and retrofitted equipment from light duty vehicle air conditioners to refrigerators—the state will closely follow Obama-era updates to the Environmental Protection Agency’s Significant New Alternatives Policy that limited HFC use where safe alternatives are available. Those rules would have helped steer the U.S. toward compliance with the Kigali Amendment, a global agreement to phase out HFCs that was negotiated in late 2016. The amendment was expected to stave off up to half a degree of global warming.

But while the Trump administration initially voiced support for the Kigali Amendment, a federal appeals court struck down the HFC regulations last year, with the court’s majority opinion (authored by none other than Supreme Court nominee Brett Kavanaugh) stating that EPA’s authority to regulate ozone-depleting substances “does not give EPA authority to order the replacement of substances that are not ozone depleting but that contribute to climate change.”

In April, now-vanquished EPA leader Scott Pruitt decided the agency would no longer enforce the Obama-era rules at all. And although business leaders and even Senate Republicans have urged President Trump to send the Kigali Amendment to Congress for ratification, there’s no sign of that happening anytime soon.

Now, New York state aims to steer the cooling industry toward more climate-friendly alternatives to HFCs without federal aid. It’s not alone: California also has a policy on the books requiring the phase-out of these substances, and Cuomo is urging other states to jump on the bandwagon.

In the climate policy world, HFCs are low hanging fruit. Perhaps there’s hope yet they can be eliminated.

Allright, allright a less dumb comment. It’ll still be a dumb and clunky comment - just less so than the other one. And germane to the subject matter. btw, Maddie rocks.

Thankfully NOAA continues study on climate forcing (greenhouse gases and heat accumulation), but sadly without help from US EPA. You see, republicans with help from our president Donald J. Trump thought it best to pull EPA out of the climate business to focus on... well to focus on nothing, really so MAGA can move forward. Anyway, here’s a recent report (May 2018) from our friends at NOAA office in Boulder, CO

NOAA’S GREENHOUSE GAS INDEX UP 41 PERCENT SINCE 1990

A cool graph on how well GHGs are accumulating in the atmosphere. Actually, by well I mean bad.

From the first graph below it is obvious to even the most casual observer that CO2 concentration in atm is rising swimmingly upwards. Not good. Real bad. Nitrous Oxide (the propellent in whip cream cans that kids steal from the refrigerator section at 7-11 to get high of off) continues to accumulate in the atm. Dumb kids. Methane slowed down during the late 90s and early aughts as emissions controls were thought of as a good thing. That is until the shale oil and gas revolution went balls-to-the-wall apeshit and the some odd billion Chinese got their first taste of a Burger King whopper sandwich. And more biggass dams got built. And lastly all those refrigerants with either a fluorine or chlorine molecule glommed onto an ethyl molecule. It’s funny how CFC in atmosphere concentration started to go downward when international agreements and regulations were applied. Sadly, those agreements and regulations are becoming things of the past. The free market with woke corporations, MAGA, and greenwashing from a bunch of center-center third way environmental non profits don’t need no stupid mean spirited regulations.

Carrying on with another graph from NOAA Boulder’s report. As we all can see, a lot of shit is adding up to contribute to that global warming thing.

Sorry for the excessive white space above and below the following graph. Some asshole who made the graph probably did that when making a jpg. God, what an idiot. Fucking Boulder.

The thing to keep an eye out for are the “15 minor” GHGs. They’ll be doing a lot more of the groundwork to, as they say, lift the curve. One molecule of HFC-23 (branding as Coldasfuck(TM)) is like putting 12,000 carbon dioxide molecules in air. Table is from the latest IPCC report so find it yourself. I’m too lazy to link.
