Volcanism and Climate

Void · Today 12:15:41

Perhaps it is the news media, but I seem to notice many reports of volcanism around the planet.

I am not going to try to argue that humans produced CO2 does not warm the planet.

But what if on a planetary basis, cooling effects from volcanism is not linear but is periodic. Does the whole Earth start shaking itself up periodically and produce more volcanism around the planet?

My point being, do we really want to reduce the CO2 content in the Earth's atmosphere?

Little Ice Age and CO2
The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region, from the 16th to the 19th centuries. It was not a true ice age of global extent, and the term was introduced into scientific literature by François E. Matthes in 1939. The LIA is conventionally defined as extending from the 16th to the 19th centuries, but some experts prefer an alternative time-span from about 1300 to about 1850. The NASA Earth Observatory notes three particularly cold intervals: one about 1650, another about 1770, and the last in 1850, all of which were separated by intervals of slight warming.

Several causes have been proposed for the LIA, including cyclical lows in solar radiation, heightened volcanic activity, changes in ocean circulation, variations in Earth's orbit and axial tilt, and inherent variability in global climate. The Intergovernmental Panel on Climate Change Third Assessment Report (TAR) of 2001 described the areas affected by the LIA, suggesting largely independent regional climate changes rather than a globally synchronous increased glaciation.
Climate Change Dispatch
The relationship between CO2 and warming, known as climate sensitivity, determines what future we should expect as CO2 levels continue to climb. New research led by the University of Washington analyzes the most recent ice age, when a large swath of North America was covered in ice, to better understand the relationship between CO2 and global temperature. The study finds that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.

So, do we want to risk mass starvation some day?

I know the green solution: Kill most or all of the people and nobody will starve.

Anyway, could the Earth be a bit like a geyser? Build up geothermal energy, and then start shaking, triggering events around the planet.

Maybe? Maybe not?
