Read here and here. Researchers keep discovering aspects of the Earth's climate system that completely undermines the credibility of climate alarmist scientists and existing climate models. In the case of the climate models, submarine volcanoes (whether one, or three million) are not accounted for despite everyone knowing they must have some major impact on our climate. These volcanoes spew millions (billions?) of tons of CO2 and other compounds into the oceans and researchers are just now starting to theorize and document what effects may be occurring as a result.
Are volcanoes contributing to ocean acidification?
"It was the distinct lack of acidification of all the planet’s other water sources that prompted researchers to investigate why oceans alone were showing signs of increasing acidification....if human atmospheric emissions of carbon dioxide were causing the oceans to acidify then why weren’t we seeing the same levels of rising acidity in rivers and reservoirs?....By finding no increases anywhere in inland water systems this study has inevitably concluded that any human emissions into the atmosphere of carbon dioxide must be excluded as a potential source of oceanic acidification."
Are volcanoes slowing climate change?
"A vast network of under-sea volcanoes pumping out nutrient-rich water in the Southern Ocean plays a key role in soaking up large amounts of carbon dioxide, acting as a brake on climate change, scientists say...A group of scientists have shown for the first time that the volcanoes are a major source of iron that single-celled plants called phytoplankton need to bloom and in the process soak up CO2, the main greenhouse gas."
Can volcanoes change the climate? New studies confirm that volcanoes can cause massive change.
