It's a pity we don't have the measuring equipment that we do now, further back in time, so records would be based on like for like recording.
Just think back in the middle ages when we had a mini ice age for a couple of hundred years, we could have said 'Oh noes Man farked it up, we've not warmed up the planet enough'
Look through the geological history of the Earth, there's been times when we've been locked in ice, there's been times when the planets been a tropical jungle, what we've managed to record in the last few years wouldn't even constitute a coffee break in the life of the planet. Look instead to greedy politicians, scaremongers and the like.

Looking further into it,its not as simple as that, you also need to factor in plate tectonics, opening and closing parts of the world to ocean currents (this is huge btw) as far as climate change can go, also consider that over time the sun is gradually increasing in intensity & radiation (getting brighter & hotter)

Some evidence does exist however that the period of 2,000 to 3,000 million years ago was very generally colder and more glaciated than the last 500 million years. This is thought to be the result of solar radiation approximately 20% lower than today. Solar luminosity was 30% dimmer when the Earth formed 4.5 billion years ago,[9] and it is expected to increase in luminosity approximately 10% per billion years in the future.[10]
On very long time scales, the evolution of the sun is also an important factor in determining Earth's climate. According to standard solar theories, the sun will gradually have increased in brightness as a natural part of its evolution after having started with an intensity approximately 70% of its modern value. The initially low solar radiation, if combined with modern values of greenhouse gases, would not have been sufficient to allow for liquid oceans on the surface of the Earth. However, evidence of liquid water at the surface has been demonstrated as far back as 3,500 million years ago. This is known as the faint young sun paradox and is usually explained by invoking much larger greenhouse gas concentrations in Earth's early history, though such proposals are poorly constrained by existing experimental evidence.

As you can see, there's many many other factors to consider beyond what any single species can achieve since the Industrial age.
