We already knew that the hydrochlorofluorocarbons (HCFCs) used to replace ozone-destroying chlorofluorocarbons (CFCs) are proving to be a super greenhouse gas—4,500 times more potent than carbon dioxide. Nevertheless, we’re still using them in everything from spray cans to refrigerators to air-conditioners.

Now a new paper in Journal of Physical Chemistry finds that HCFCs may also be increasing acid rain. Computer models show HCFCs break down in the upper atmosphere to form oxalic acid, one culprit in acid rain.

The researchers suggest the new computer model could help determine whether replacements for the replacements are as environmentally friendly as they appear before manufacturers spend billions of dollars marketing them.

The paper’s open access online.
 

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
