Not necessarily, but many human activities of the last 150 years sure have.

Yes, because the vast majority of scientists, who know more than I and likely more than anyone else on this site, agree that humanity is the cause of global warming.

it's less of matter of belief and more about the data, and I haven't been looking at it lately TBH. but I will say I am inclined to believe all the scientists in my community (and beyond) who think that it does.

Hopefully. I mean, we are already overdue for an ice age.

Snow in March is the norm here now in the last few years. Hotter summers too. And more storms and even a tropical hurricane hit us. Unusual for Ireland. We are used to just the sky pissing cold mist all the time. So yeah there's a shift obviously. Its the end of results of our carbon footprint as they call it. Built up over many years.

We have an impact but I don't know how strong it is. It is certainly bullshit that earth will be history in 12 years or something like that. Is it true that climate scientists in the 70s said, that soon all trees will be gone? Was BS as well. Of course most of us are horrible children to our mother earth, we need to change shit for the better.
