On Deep Sea Volcanoes and Ocean Warming: Reprint

Since we regularly get questions about this type of thing, I wanted to repost this excellent post from Erik Klemetti's blog 'Eruptions.'

"I recently read a post about how humans couldn't be to blame for the warming of the oceans.    
The "logic" of their post was this:

  • We see water getting warmed by magma at volcanoes worldwide, like Taal andRuapehu.
  • The bottom of the ocean is covered in volcanoes, whether it be seamounts or the mid-ocean ridge system.
  • Volcanoes at the bottom of the ocean must heat up the ocean water (like in crater lakes), so humans aren't to blame.

There are a number of ways to attack this poor reasoning, but I'll try to go with the ones I think are most convincing.

Boulders spew from Ecuador Tungurahua

The Daily Mail News Report had some great pictures of the ongoing activity at Tungurahua!

Kamoamoa, which cracked open Saturday, is continuing to spew out loads of lava and gases. Meanwhile, visitors flock to Hawaii Volcanoes National Park hoping to catch a glimpse of the 2,000-degree Fahrenheit (1,093-degree Celsius) glowing, red-orange lava that is shooting 65 feet (20 meters) high. But visitors are being kept far away from the isolated, remote east zone rift where the eruption is taking place.
