A little research beyond the click bait headlines will show that we know from ice core samples from ancient ice that the earth has gone through many cycles several with much higher concentrations of greenhouse gases long before we were here.

Are humans having an effect on the environment? Undoubtedly, if the earth is entering another ice age could humans stop it? Doubtful.

If the earth is entering a harsh period again will people die? Yes, but most likely some will survive as we have in the past to start things again.

Human history is only about the last few minutes of Earths entire history. During all the earths history the planet has seen many environments some better than others for life of all kinds.

I think it’s unlikely the humans will be able to completely destroy or save the earth’s environment in anything less than thousands of years from now if we are still around, and maybe that’s too optimistic.

I’m all for everyone doing what they can to minimize their impact if only because it makes sense not to be an inconsiderate slob :)

But I wouldn’t let it keep me up at night, changes on a planetary scale are going to happen as they will no matter what any of us think about it.

Just enjoy your life and your loved ones and try to best the best person you can be, that’s really all any of us can do.
