Humans have caused 1.5 °C of long-term global warming according to new estimates

Asking sincerely because I'm not well-versed on this topic - do we have actual proof that humans are causing global warming?

My understanding is that the climate will change independently of human activity. For example, we know that there was an Ice Age and it was not ended by human activity but rather natural processes. So the climate has been known to change historically without human involvement.

So here is where I'm looking for clarification: I thought the "controversy" over climate change was the degree to which human activity is accelerating a natural process of warming?

Said differently, the planet is warming by itself, but humans pumping hydrocarbons and other things into the atmosphere is speeding up that process. But the cause is not solely because of human activity.

Thanks in advance for thoughtful responses, I'm really just trying to learn here.

Before your comment (and mine) gets flagged to death, I wish to provide this information that might be of interest:

Yea, the climate change narrative is highly overblown, but it will take a few more years before the overtone window shifts for larger swaths of people in power to accept it.

How hard are you really trying if you're asking early 2000s climate change questions on a VC forum.

The rate of change in climate (due greenhouse gas inputs from human activity) is much faster than it has occurred naturally in the past. If you are genuinely curious, the US EPA's climate change indicators report would be a good place to start. https://www.epa.gov/climate-indicators/climate-change-indica...

Yes. See this comment [1] for an explanation of how we know that humans are largely responsible.

Thank you for your thoughtful and informative reply. I learned something from reading this and that was my goal.

Harder than you for sure since I learned nothing from your low-effort and shaming comment.

Thank you for sharing. I will take a look to educate myself, which is my goal.

No we don't have w proof. We also have sufficient evidence it is not causes by humans, but this doesn't suit the narrative.

So keep the wood burner on!
