Eyjafjallajökull's current eruption is releasing approximately 15,000 tons of carbon dioxide (CO2) daily, significantly less than the European aviation industry's output of 344,109 tons per day. This stark contrast highlights the dominance of human activities in CO2 emissions, as they produce 130 times more than all volcanoes combined annually. Discussions also touch on the potential dangers of the neighboring Katla volcano, which is closely monitored due to its history of more significant eruptions. The conversation includes logistical concerns for residents in east Iceland regarding travel disruptions caused by volcanic activity. Overall, the thread emphasizes the relatively minor impact of Eyjafjallajökull compared to human-induced emissions and the need for vigilance regarding Katla.
