When did Global Warming start?

This site http://www.al.com/news/index.ssf/2015/05/how_many_hurricanes_will_we_ha.html
has kind a cool chart that shows the Atlantic hurricane activity since 1851
It generally looks pretty uniform.
So did Global Warming start before 1851?

It started during the industrial age that began around 1760 in Great Britain. However, up up until the 1900’s I’d say the footprint was small.

What was the Earth’s temperature in between 1760 and 1900’s?

I think about 1840. Eli Whitney invented the cotton gin and the US alcohol consumption skyrocketed and all the male urine caused a rise in the global temperature.

If the earth cooled, causing the ice age, didn’t global warming start as soon as that trend started to reverse?
We are freaking out now that the glaciers are melting, would we be freaking out of new glaciers were forming?

the Earths climate is cyclical going from cold to warm and back again. In this particular warming cycle I believe it started in the mid 1800’s. I could be mistaken here, it could have been that the increase was more dramatic since that time but warming started a couple of centuries earlier. I need to look it up.

@Dutchess_III is right, it was the Industrial Revolution that brought it on. The global temperatures in that period aren’t particularly relevant though.

Basically the emission of greenhouse gasses causes global warming. But the two factors don’t linearly correlate. When the Industrial Revolution kicked off, the oceans absorbed much of the carbon dioxide. Their vast volumes meant that there was probably little to no effect on the environment during this period, besides the occasional acid rain.

We’ve been burning so much for so long though, that the oceans aren’t absorbing as much as they once did. More is going into the atmosphere, and the effect compounds. We’ve also lost huge amounts of forrest, which has again compounded the effect. We’re going past the tipping point. There was no great environmental impact until a few decades ago. But we’ve been hurtling towards it since the Industrial Revolution.
