still, I see no serious action being taken to tackle the climate crisis. Current governments are just putting some dates by which we’ll stop doing x or y, but in really almost nothing concrete is done to stop the worst scenarios.
Whatever current event you're concerned about, have you looked for historical precedent? Suppose you were to discover that the same kind of event had happened in, say, the early 1900s, and/or the late 1800s, before humans had emitted any appreciable amount of CO2. Would that change your opinion about whether we're in a crisis?
We're not reinventing any phenomena because we're emitting CO2, we're just putting the foot on the gas pedal, both literally and metaphorically. Same argument occasionally crops up during the pandemic. Yes, we've had them before, but that doesn't make this one any less bad, and interacting with animals that spread zoonotic diseases any less dangerous
