Mind you, this graph only represents approximately 10.87% of 4.6 billion years the Earth has existed.
Not so fast... I'm not going to argue your beliefs, but I will treat you to a geologic map on the order of 10,000 years, which is nearest-neighbor to your belief of 6,000 years being the origin timeline of Earth. In the graph below, using geologic evidence, you can see the same general temperature curve as in the much longer timescale. We're still in a relatively "cold" period of geologic time, however you slice it. I'll take your checkmate now, thanks.

Melting ice is slowing Earth's spin, shifting its axis and even influencing its inner core, research shows
Two new studies suggest human behavior has changed foundational elements of the planet’s physical properties.

The vast amount of time where earth was uninhabitable is good reference data. Maybe one day we can get there again!
When was that. By the way, I'd correct sir wax's post to say we have less than 100 years of truly reliable data.
Until about 800,000 years ago there was basically no free oxygen in the atmosphere.
Climate didn’t support human civilization until about 12,000 years ago.
So the remaining 4+ billion years were not really good times for life as we know it.
You're wasting your time with death-culters, they don't care if their grand children never have the chance to see a wild animal or if our population gets cut down to a couple million eking out a middle-age existence. As long as they get own the libs and roll coal who cares what the world they leave behind looks like.
I’m not trying to convince anyone that humans are causing global warming.
I just find the “it has been a lot hotter before“ argument interesting. It’s not a matter of whether the earth has been hotter, it’s a matter of how humans might /might not continue to thrive under those circumstances.
Earth has been teeming with oxygen-breathing life for hundreds of millions of years. Swing and a miss, bro.
The “great oxygenation” occurred about 2 billion years after earth formed but didn’t produce oxygen at levels necessary for growth to really occur. It remained at very low levels (only about 10% of today’s level) for about another 2 billion years. It wasn’t until plants started to flourish about 450,000,000 years ago that sh!t got moving. Mammals didn’t develop until about 65,000,000 years ago.
As a mia culpa, my 800,000 number was way wrong. It was more like 80,000,000.
