> Is climate change man-made?
When having the climate change conversation with deniers I roll it back to; is the climate warming? They almost always[0] agree it is and we agree it’s evidenced. So now we’ve agreed on a fact and have common ground to advance the conversation. Then I can make my case that if we know the climate is warming then we have a responsibility/necessity to reduce our contribution to it and should likely invest in finding ways to reverse it. Because even if we are not the cause, we have a lot at stake.
[0] in rare case they can’t agree to this, I usually ask them if they’ve encountered a source for that and then ultimately implore them to at least read something on the topic before forming their opinion about it, there’s plenty of data available I won’t push them down any path that may be seen untrustworthy or politically misaligned with their beliefs, I just leave it alone there because it’s usually quite obvious they’re parroting the talking points of some pundit without doing any research themselves. As the article mentioned, this argument would just become an ego war more than anything.
i disagree that it' warming, so where do you start with me? I'm not being coy, i 100% believe that all of the warming detected is strictly down to poor placement of sensors and incorrect assumptions thereof in the resultant data. So what we will end up arguing about, if we get past that particularity of my thoughts, is about models. And i hate arguing about models.
edit: i think probably the cities are getting "warmer" but that's not climate change that's city change. In that cities are growing, generally, with more stuff paved over. We need to plant more trees and have less concrete/asphalt in cities if we want to reverse this trend. also less people, but that's not going to happen anytime soon.
Do you doubt that greenhouse gases being emitted into the atmosphere have gone up since humans started burning fossil fuels, and do you doubt the physics of how they trap solar radiation? Do you doubt that climate scientists know how to put sensors in the oceans, in rural areas and released in weather balloons along with satellites to measure temperatures across the planet year by year? Or that they can extract ice cores to measure trapped atmospheric gas from thousands of years ago? That sort of thing.
