Mother Nature Way to curb global warming?

Is volcano eruption a way to curb the global warming, the Mother Nature way at least?

Since industrial revolution in 18th century, CO2 concentration (refer top graph) in the atmosphere is keep on increasing and the global temperature also increasing accordingly. From the earthquake/volcano activity statistics data, it has been inceased from 1970 (4139) to 2003 (31419). Are they linked to each others? Increasing of CO2 in the atmosphere (in another word, temperature rise) link to more earthquake/volcanic activity? Maybe global warming can inject "extra" heat to the super heated lava under the earth tectonic plate, causing them easier to erupt? Just my conspiracy theory, thanks to Malaysia's politic.

Everytime there is a big volcano eruption, tonnes of ash and sulphure dioxide will blow to the atmosphere, besides create much problem like what the Iceland's volcano does this time, it will also reduce the global temperature thanks to the sulphure dioxide and the ash.  

For example of Mount Pinatubo of Philippines, erupted in 1991, millions of tonnes of sulfur dioxide were discharged into the atmosphere, resulting in a decrease in the temperature worldwide over the next few years. The cloud over the earth reduced global temperatures. In 1992 and 1993, the average temperature in the Northern Hemisphere was reduced 0.5 to 0.6°C and the entire planet was cooled 0.4 to 0.5°C (refer graph below, from IPCC's report).

Therefore, i guess, volcanic eruption is a way that she tell the human, "you all created the mess and i am the one who need to clean it up. Now eat the ash (and flight cancel)!".

So time to mitigate GHG, start from your lifestyle!
Time To Change!

At least something positive from the eruption. God is great.
