This article is spot on, I really dislike the doom and gloom messaging that is common to attempt to motivate people into action. It makes people feel hopeless. Climate change solutions all have other more immediate benefits for say human health or financial safety, or even just preventing deforestation. It's more motivating to emphasize the benefits of doing something rather than the consequences of not doing it.
Even with major corporations being the primary culprits of climate change, individual choices of people add up. Taking public transit or biking, improving energy efficiency/home weatherization, eating less meat, and generally getting off of fossil fuels often provides the greatest benefits to the people who make those changes.
IMO I think the “doom and gloom” messaging has backfired into apathy and nihilism. Yes we should be honest with the seriousness and severity of the situation but I think it’s more important to provide and message hope. Also provide solutions, alternative economic systems, simpler and happier lifestyles, and especially pathways to off-ramp from the consume till we die society that we currently live in.
On top of those, it's important to support politicians who will make doing the right thing the normal default choice. I've got a note about how to do that in the US
