I think this article identifies a genuine problem but comes up with the exact wrong solution.
The problem is accusations of perceived hypocrisy. Climate opponents claim that climate professionals aren't living their values. They dictate rules for living to others that they don't follow themselves. This makes climate professionals look dishonest and untrustworthy, and is used not just to discredit individual advocates but call all of environmental science and policy into question.
The solution the article suggests is to stop accusing climate scientists of hypocrisy because we all have to live in a broken system. Which is absolutely true. We do.
However. The people who accuse climate advocates of hypocrisy aren't going to listen to that.
Here's the way I see it. In the conversation, we have climate supporters, who believe in the science and want good climate policy; climate opponents, who want to block good climate policy; and undecided people, who don't know about the science and/or don't have strong opinions on policy.
Accusations of hypocrisy against climate professionals come overwhelmingly from climate opponents. The purpose of these accusations is to sway undecided people, who don't know much about the science and who give more weight to the perceived trustworthiness of climate professionals, and their fellow climate opponents, to discourage them from listening to climate professionals and possibly changing their minds.
And then people who hear these accusations repeat them to their friends and neighbors and family. And if people have friends or neighbors or family who they personally know aren't living their purported climate values, those accusations start sounding even more credible.
Look. The average American is not an expert on climate science. The average American doesn't understand, in detail, the data and the sources behind the data. In order for the average American to believe in climate science, they need to trust climate scientists to be honest and provide truthful data.
The average American does understand hypocrisy and morality. And when climate professionals are credibly accused of behaving in ways inconsistent with their stated values, that harms Americans' trust in the climate science.
Telling climate opponents not to accuse climate professionals of hypocrisy is pointless. They do it because it works. They will keep doing it because it works. Because their goal is to block climate policy and they'll use whatever tools they have to do that.
Which is why, I think, it's important for climate supporters - especially climate advocates - to live their values as far as they can, and to be able to talk about how they live their values. And when they're not able to live their values - for instance, climate advocates needing to fly around the country for political rallies to build collective action - they should be able to explain why they're not living their values and how they're trying to make up for it in other areas.
So that when some friend or family member repeats a "gotcha" like "but you flew to Dublin for an environmental conference, lol" you can respond with "Yes, and I offset that consumption with x, y, and z, and I signed a petition to make next year's conference virtual, and" etc, etc, etc. Show that the environment matters to you morally and that you are trying to do the right thing. Not only does it deflect the accusation of hypocrisy but it makes you appear more credible on the science.
It may not seem like it in the current political climate, but honesty still matters. Consistency still matters. Honor still matters.
And whether you're Taylor Swift, burning enough jet fuel to heat a small country, or Joe Public the EPA paperwork drone, leaving your car running in the driveway for twenty minutes to warm it up before work, your personal consumption does matter. And the example you set to people who know you matters even more.
