Aerosols from volcanic
eruptions do have a cooling effect once they reach the stratosphere but the effect of high wind speed in the upper atmosphere would rapidly disperse these, and any local effects would be very slight.
A climate scientist with impeccable credentials claims that we can safely keep the earth cool for many decades in the same way that volcanic
eruptions do — by putting sunlight - blocking material in the stratosphere.
Volcanic eruptions don't necessarily need to cause significant cooling.
For $ 10 billion per year we can keep the earth cool for decades in the same way that volcanic
eruptions do — by putting sunlight - blocking material in the stratosphere.
Focusing on supporting your skin's inflammatory response will help reduce breakouts and prevent scarring when
eruptions do occur.
That's because scientists have presumed that most of the aerosols from minor
eruptions do not rise beyond the troposphere, the layer of Earth's atmosphere where weather occurs and where natural processes quickly clear particles from the atmosphere.
«On Earth, eruptions don't tend to continue for long,» said Edwin Kite, assistant professor of geophysical sciences at UChicago.
But we do know that if
an eruption does occur, it will affect the 360,000 people living across the caldera, and the nearly 1 million people living in Naples proper.
And the population living on the volcano may be under even greater threat: Not only could an errant
eruption do them in, but because they are specialized to only one type of plant, if that plant dies out, the bees would be left with nothing.
The volcanologist explains that the lack of a major volcanic
eruption does not necessarily indicate that magmatic activity has come to a complete halt.
«Observations show that a sub-glacial
eruption did not occur yesterday.
Their findings: natural influences such as changes in the amount of sunlight or volcanic
eruptions did not explain the warming trends, but the results matched when increasing levels of greenhouse gas emissions were added to the mix.
We conclude that the hypothesized «volcanic winter» that followed the Toba
eruption did not have a significant impact on the climate of East Africa and was not the cause of a human bottleneck in Africa around 75 ka B.P.
Investigation of ash sediments from recent Mt. Pinatubo eruptions and other major volcanic events show a signature of mass independent isotope ratios of sulfur, while sediment from minor
eruption does not.
The following is a news item, so I'm not sure if it reliably reflects the evidence, but it suggests that the eruption didn't spew enough sulfur dioxide into the atmosphere for significant climate effects — Chile Volcano.
Aerosols emitted for only a short time would have minimal effects that subside very quickly.The industrial aerosols are rich in SO2, while apparently, the Chilean volcanic
eruption did not (according the news item) spew enough SO2 into the atmosphere for discernible climate effects.
The fact that models are hindcasted to the ice - ages and volcanic eruptions doesn't impress me one bit.
Even wacking it with an asteroid the size of France and setting off multiple huge volcanic eruptions didn't cause much long - term upset.
Ryan (09:58:28): Even wacking it with an asteroid the size of France and setting off multiple huge volcanic eruptions didn't cause much long - term upset.
For instance, given the physics of sulphate aerosols in the stratosphere (short wave reflectors, long wave absorbers), it would be surprising if putting in the aerosols seen during the Pinatubo
eruption did not reduce the planetary temperature while warming the stratosphere in the model.
