Okay you should probably read up on sanitary conditions in the 19th century. Horse excrement all over the streets etc.
It's honestly laughable (and a little sad) that you're comparing the environmental impact of horse manure to that of global warming, but you're the expert in horseshit.
But that was a tangible issue at the time. Global warming isn't.
You should probably read up on the tangible effects of climate change since you're under the impression that there aren't any (here's a link to NASA's climate change website:
https://climate.nasa.gov/effects/).
It doesn't affect our daily lives now,
It does affect our daily lives. The most obvious example being the growing frequency of extreme weather activity, including droughts, heat waves, and floods (you can read about that here:
http://nca2014.globalchange.gov/highlights/report-findings/extreme-weather).
we don't even know if reducing emissions will even stop the warming trend.
The mainstream scientific community would tell you that this is not accurate. Reducing the amount of greenhouse gas emissions would more than likely slow the trend of rising global temperatures, if not reverse it.
It's more of a "meh, better to try something than nothing."
No, it's more like a "let's be proactive in order to avoid a global catastrophe that would threaten the future of our species" sort of thing.
I'd rather us spend the money working on ways to adapt to warmer temperatures rather than spend trillions in the hope that it reverses its trend.
I'd rather that you take the time to understand a subject before shooting your mouth off about it but we can't all have what we want.
