Increased volcanic activity is one of the culprits, he answers.
31 Oct 2014 – (Excerpts) – “We are being beaten by a one two punch,” says Dr Sircus. “From one side we have the sun diminishing its radiance and on the other volcanoes have gone berserk these past few years.
The head of the Space Research section of the Russian Academy of Science, Professor Habibullo Abdussamatov, in 2006 issued a press release, warning that the world should prepare for imminent global cooling. He predicted that the global cooling would start in 2012 – 2015, and would likely peak around 2055.
The Russians did not calculate into their predictions these record breaking volcanic emissions into the atmosphere. Alone the sun was throwing us into cooling.
Increasing volcanic eruptions have been spewing ash into the atmosphere over the last 14 years are partially responsible for the cooling of Earth…a recent study published in Nature Geoscience suggests. Researchers attribute this helping hand to just 17 of the eruptions from 1998 to 2012 that pumped sulfur dioxide into Earth’s upper atmosphere. The molecule formed liquid particles that reflected sunlight back to space rather than to the Earth’s surface.
The average number of volcanic eruptions per year should be about 50 to 60; as of December 5, 2013, we were already at 83.
The number of volcanoes that are erupting continues to rise. In 2013, we witnessed the most volcanic eruptions worldwide that we have ever seen in a single year, and this increased activity has carried over into 2014. The previous number was set in 2010, at 82 volcanic eruptions for the year. The number of volcanoes erupting across the planet has been steadily rising from just 55 recorded in 1990. The average number of volcanic eruptions per year should be about 50 to 60; as of December 5, 2013, we were already at 83.
More sunlight being reflected back into space
“In the last decade, the amount of volcanic aerosol in the stratosphere has increased, so more sunlight is being reflected back into space,” said lead author Benjamin Santer, climate scientist at Laurence Livermore National Laboratory, in a press release. “This has created a natural cooling of the planet and has partly offset the increase in surface and atmospheric temperatures due to human influence.”
If this winter is even worse than the last one we are going to be in for a hard time. Having a month to six weeks shaved off our collective growing season suddenly is going to have grave consequences in a world already with a short supply of food.
If sulfur dioxide forms liquid particles that reflect sunlight back to space rather than to the Earth’s surface, then how much cooling will result from the massive amounts of sulfur dioxide being emitted by Iceland’s Bardarbunga Volcano? (35,000 tons per day!)
