1-degree increase first 0.5 from late 1800 to mid 1900 when we didn't emit much CO2 second 0.5 degree where we emitted a lot.

You were the one claiming your graph illustrated something.

You have no basis for this claim:

"And again, most of the effect from the greenhouse gasses released over the past 50 years hasn't been seen yet,"

Of course, it has and as we have learned it doesn't have as big an impact as we thought it had which is why they had to adjust it down.

By your logic, the increase in temperature from the first half of the last century was also then delayed from earlier in the 1800s where we used even less.

So perhaps you should consider if it's you not me who should be open to new information.
