I’d be the first to speak out against climate change, but I’m not sure I understand how co2 is relevant? The current ambient co2 in the world ranges around 400-500 ppm. It can easily get into the thousands indoors and that doesn’t impact birds. It seems like we’re a long way off from ambient co2 causing an issue with wild birds?
My dog sleeps next to my thighs. She’s small, but under a sheet, a blanket, and a comforter, the CO2 has to be through the roof. Nevertheless she hears my alarm before I do and at 5:25 is wide awake.
The two that hang out on my property seem to have raised several chicks to adulthood successfully the past 4 years I've watched them.
It seems like they can adapt if they're just left alone
Nature will do fine with increased co2, bar arctic/antartic turmoil, it'll not be a big problem. The far bigger problem is that places where nature can even be gets occupied by humans or their farms and logging.
Correct, habitat loss from human settlements and agriculture is a far greater threat to the natural environment than CO2 emissions. CO2 emissions have actually resulted in massive greening around the world:
