The shape of the curve is driven by the independent variable (CO2 concentration, volcanic activity, etc).

And pray that the same amount of CO2 is never spewed through a volcanic eruption, unless you long to die in a volcanic apocalypse.

Data mining tidbit: 'For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms.

Injecting sulphur dioxide into the atmosphere for example, mimics how some volcanic eruptions cause temporary cooling.

There are real challenges and a volcanic ejection certainly is one of them, it's just not anywhere up the list.

Both of these mimic natural events such as volcanic eruptions; they're not unprecedented in nature.

However this does not mean that very large volcanic eruptions won't have an impact on global temperatures when ash is thrown up high enough to block out the sun.

They're caused by earthquakes (or volcanic eruptions, nuclear explosions, or other literally earth-shaking events).

What has never been established is a link between volcanic activity and global warming.

This article is about climate change and volcanic activity during the roman empire.

The effects of greenhouse gases are mild compared with planetary collisions or large volcanic eruptions so it's unlikely any positive feedback loop will occur.

It's actually a plume from a volcanic eruption, which is even crazier.

It's puzzling why mentioning volcanic eruptions and climate change is considered a "straw man" to you when the article is about volcanic eruptions and climate change.

"What has never been established is a link between volcanic activity and global warming." Like this article?

To quote from the book's marketing literature: "In AD 536, a volcanic eruption meant our planet was enveloped by a cloak of lethal dust which changed the climate for decades.

It mentions "a summer without heat" and that "15 of the 16 coldest summers recorded between 500 BC and 1,000 AD followed large volcanic eruptions".
