PDQ -- are you proposing that the increase in global temperatures is caused by itchy volcanic action?

If so are you asserting the increase in volcanic action is sufficient to account for it?

Actually, interestingly the second great blowout of Krakatoa, between Java and Sumatra in Indonesia, occurred around the beginning of the industrial revolution in 1883. e explosions were so violent that they were heard 3,500 km (2,200 mi) away in Perth, Western Australia and the island of Rodrigues near Mauritius, 4,800 km (3,000 mi) away.[5] The pressure wave from the final explosion was recorded on barographs around the world, which continued to register it up to 5 days after the explosion. The recordings show that the shockwave from the final explosion reverberated around the globe 7 times in total.[9] Ash was propelled to a height of 80 km (50 mi).

An earlier eruption of the same volcano, it is thought, in 535 was (coincidentally) the final death-knell of the Roman empire.   According to some reports the eruption was so loud it was recorded as having been heard in China.   

But the explosion of Krakatoa in the nineteenth century actually depressed worldwide temperature readings for two or so years.
