It seems like you won't have any trouble finding that yourself if you really wanted to. This "I'm just asking questions" mode you're in can be considered a type of trolling called "sealioning".
On that graphic -- under the heading 'Ice cores (from 800,000 years before present)' in case the link gets truncated -- one can observe regular peaks in temperature that took place before the current one. I'm happy to be explained what caused them, as it could not have been human industrial activity.
That's it. I'm open to dialogue but won't entertain any more lazy dismissals and unfair characterization.
