Bardarbunga eruption gases estimated - BBC News

As well as the predominant species, SO2, the team estimated just over 6.5 million tonnes of carbon dioxide was released, together with roughly 110,000 tonnes hydrogen chloride.
Bardarbunga-Holuhraun was one of the biggest effusive eruptions in Iceland’s recent history, spewing more than 1.5 cubic km of lava – but it was still quite tame compared with earlier entries in the record books.
The infamous Laki event of 1783-84 threw up 15 cu km of lava and probably produced some 110 million tonnes of SO2.
Its effects were felt far and wide, with parish records in England at the time reporting large numbers of deaths that have since been attributed to respiratory complications, to the harsh winter that followed the eruption, and to famine. On one level, it may appear surprising that more health complaints were not reported following Bardarbunga-Holuhraun.

While we are on the subject of historic volcanic eruptions, here is some info on Krakatoa, one of my favorites.

Krakatoa Volcano: Facts About Deadly Eruption

"The eruption of Krakatoa in August 1883 was one of the most deadly volcanic eruptions of modern history. It is estimated that more than 36,000 people died. Many died as a result of thermal injury from the blasts and many more were victims of the tsunamis that followed the collapse of the volcano into the caldera below sea level.

At 12:53 p.m. on Sunday the 26th, the initial blast of the eruption sent a cloud of gas and debris an estimated 15 miles (24 km) into the air above Perboewatan. It is thought that debris from the earlier eruptive activity must have plugged the neck of the cone, allowing pressure to build in the magma chamber. On the morning of the 27th, four tremendous explosions, heard as far away as Perth, Australia, some 2,800 miles (4,500 km) distant, plunged both Perboewatan and Danan into the caldera below the sea.

Tephra and hot volcanic gases overcame many of the victims in western Java and Sumatra, but thousands more were killed by the devastating tsunami. The wall of water, nearly 120 feet tall, was created by the volcanoes’ collapse into the sea. It completely overwhelmed small nearby islands. Inhabitants of the coastal towns on Java and Sumatra fled toward higher ground, fighting their neighbors for toeholds on the cliffs. The steamship Berouw was carried nearly a mile inland on Sumatra; all 28 crewmembers were killed. Another ship, the Loudon, had been anchored nearby. The ship's captain Lindemann succeeded in turning its bow to face the wave and the ship was able to ride over the crest. Looking back, the crew and passengers saw that nothing was left of the pretty town where they had been anchored.

The explosions hurled an estimated 11 cubic miles (45 cubic km) of debris into the atmosphere darkening skies up to 275 miles (442 km) from the volcano. In the immediate vicinity, the dawn did not return for three days. Barographs around the globe documented that the shock waves in the atmosphere circled the planet at least seven times. Within 13 days, a layer of sulfur dioxide and other gases began to filter the amount of sunlight able to reach Earth. The atmospheric effects made for spectacular sunsets all over Europe and the United States. Average global temperatures were up to 1.2 degrees cooler for the next five years."

Just wait till the end of the age coming soon to a planet we are ON..........The resulting mass exctinction and murder of humanity under the Kingdom of the beast, the catastrophic resuts of the seals, trumpets, thunders, wars and volcanoes/earthquakes, disease etc. will make the current probems that humanity faces look like a Saturday evening wreck in (MAYBERRY).........Barney's one bullet will not help!

[/h][h=2]Planetary sunshade[/h][h=1]Two hundred years ago this month, the huge volcano Mount Tambora erupted in Indonesia, throwing tonnes of gas and ash into the stratosphere.

Research into this is an act of desperation on the part of scientistsProf Ken Caldeira, Carnegie Institution for Science​

Are ideas to cool the planet realistic?

Maybe as much as 100 million tonnes of sulphur dioxide aerosols spread as a blanket around the globe, acting like a planetary sunshade.
Global temperatures plummeted, and across America and Europe 1816 became known as the year without a summer.
Such global cooling processes, but managed in a geoengineering solution, have been touted by some as a possible mechanism to extricate the planet from its path towards a warmer future.
Solar radiation management would use stratospheric sulphate aerosols to dim the Sun. Using a variety of climate models, Ken Caldeira, from the Carnegie Institution for Science in Stanford, California, has investigated the likely consequences of such geoengineering on agriculture across the globe.
