The 1883 eruption ejected more than 25 cubic kilometres of rock, ash, and pumice [2], and generated the loudest sound historically reported: the cataclysmic explosion was distinctly heard as far away as Perth in Australia approx. 1,930 miles (3,110 km), and the island of Rodrigues near Mauritius approx. 3,000 miles (5,000 km).

In the year following the eruption, average global temperatures fell by as much as 1.2 degrees Celsius. Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888. The eruption injected an unusually large amount of sulfur dioxide (SO2) gas high into the stratosphere which was subsequently transported by high-level winds all over the planet. This led to a global increase in sulfurous acid (H2SO3) concentration in high-level cirrus clouds. The resulting increase in cloud reflectivity (or albedo) would reflect more incoming light from the sun than usual, and cool the entire planet until the suspended sulfur fell to the ground as acid precipitation.[8]

The Year Without a Summer, also known as the Poverty Year, The Year There Was No Summer or Eighteen hundred and froze to death, was 1816, in which severe summer climate abnormalities destroyed crops in Northern Europe, the American Northeast and eastern Canada.[1][2] Historian John D. Post has called this "the last great subsistence crisis in the Western world".[3] It appears to have been caused by a volcanic winter.

It is now generally thought that the aberrations occurred because of the 5 April – 15 April 1815 volcanic eruptions of Mount Tambora[5][6] on the island of Sumbawa in the Dutch East Indies (modern-day Indonesia) which ejected immense amounts of volcanic dust into the upper atmosphere.

Other volcanoes were active during the same time frame:

La Soufriere on Saint Vincent in the Caribbean in 1812
Mayon in the Philippines in 1814
These other eruptions had already built up a substantial amount of atmospheric dust. As is common following a massive volcanic eruption, temperatures fell worldwide because less sunlight passed through the atmosphere.

If we're lucky, lower solar activity may slightly reduce global warming, but the addition of one cooling influence in no way eliminates all the anthropogenic warming trends.

Further, the solar physics group at NASA has published their own verification of a coming major solar minimum, what the SSRC's calls a "solar hibernation." The link below shows NASA's confirmation of when the next major minimum will occur as well as many other solar information links. Though the SSRC and NASA differ on the exact start of the next solar minimum (Cycle 24 vs.cycle 25, respectively) both have separately concluded a major solar minimum is coming and that premliminary signs of the sun's activity have verifed the process has begun.

Any scheme that allows a powperplant in China to belch filthy coal smoke because some rich white guy sold some credits to some rich Chinese guy strikes me as being NOT the right thing to do.

Until environmental impacts are directly priced in $, they cannot be adequitely integrated into the market.

Today, the Space and Science Research Center, (SSRC) in Orlando, Florida announces that it has confirmed the recent web announcement of NASA solar physicists that there are substantial changes occurring in the sun’s surface. The SSRC has further researched these changes and has concluded they will bring about the next climate change to one of a long lasting cold era.

Today, Director of the SSRC, John Casey has reaffirmed earlier research he led that independently discovered the sun’s changes are the result of a family of cycles that bring about climate shifts from cold climate to warm and back again. “We today confirm the recent announcement by NASA that there are historic and important changes taking place on the sun’s surface. This will have only one outcome - a new climate change is coming that will bring an extended period of deep cold to the planet. This is not however a unique event for the planet although it is critically important news to this and the next generations. It is but the normal sequence of alternating climate changes that has been going on for thousands of years. Further according to our research, this series of solar cycles re so predictable that they can be used to roughly forecast the next series of climate changes many decades in advance. I have verified the accuracy of these cycles’ behavior over the last 1,100 years relative to temperatures on Earth, to well over 90%.”

As to what these changes are Casey says, “The sun’s surface flows have slowed dramatically as NASA has indicated. This process of surface movement, what NASA calls the “conveyor belt” essentially sweeps up old sunspots and deposits new ones. NASA’s studies have found that when the surface movement slows down, sunspot counts drop significantly. All records of sunspot counts and other proxies of solar activity going back 6,000 years clearly validates our own findings that when we have sunspot counts lower then 50 it means only one thing - an intense cold climate, globally. NASA says the solar cycle 25, the one after the next that starts this spring will be at 50 or lower. The general opinion of the SSRC scientists is that it could begin even sooner within 3 years with the next solar cycle 24. What we are saying today is that my own research and that of the other scientists at the SSRC verifies that NASA is right about one thing – a solar cycle of 50 or lower is headed our way. With this next solar minimum predicted by NASA, what I call a “solar hibernation,” the SSRC forecasts a much colder Earth just as it has transpired before for thousands of years. If NASA is the more accurate on the schedule, then we may see even warmer temperatures before the bottom falls out. If the SSRC and other scientists around the world are correct then we have only a few years to prepare before 20-30 years of lasting and possibly dangerous cold arrive.”

the effects of the eruption of krakatau which happened around the same time seem to be much more well documented:


but we're only finding out about a bigger longer lasting one that happened after krakatau now.....
