After large volcanic eruptions that pump sulphur dioxide into the atmosphere, such as that of mount Pinatubo in the Philippines in 1991, the planet cools for a year or two.

Besides SSCE, scientists have also been investigating stratospheric sulfur injections — firing sun - reflecting aerosols into the air, similar to the cooling effect after a volcanic eruption — and cirrus cloud thinning, where you thin the top level of clouds, which have a warming effect on the planet.

Subsequent, unusually large and frequent eruptions of other volcanoes, as well as sea - ice / ocean feedbacks persisting long after the aerosols have been removed from the atmosphere, may have prolonged the cooling through the 1700s.

Researchers know that large amounts of aerosols can significantly cool the planet; the effect has been observed after large volcanic eruptions.

Not until after a catastrophic chain of volcanic eruptions cooled the Earth and decimated those competitors did dinosaurs become dominant worldwide.

It's also now well understood that large volcanic eruptions have a short - term cooling effect, see GW FAQ: effect of volcanic activity (short - term being the key phrase, after Church et al Nature 2005, and also http://www.llnl.gov/str/JulAug02/Santer.html)

Global cooling after volcanic eruptions has been recorded in ice core data and thermometers,: 1809, 1815, 1883, 1980 etc. and others.

The short - term variations are dominated by ENSO but also can be influenced by large tropical volcanic eruptions (such as occurred in 1963, 1982 and, markedly, 1991), so the years after those eruptions are anomalously cool.

The book was published shortly after the end of the Persian Gulf War and the planet - cooling eruption of Mount Pinatubo.

After all, the Pinatubo eruption had similar qualities but its cooling effect only lasted about a year.

The book was published shortly after the end of the Persian Gulf War and the planet - cooling eruption of Mount Pinatubo.

(For instance, do the models predict cooling after big volcanic eruptions?

We use the global cooling and drying of the atmosphere that was observed after the eruption of Mount Pinatubo to test model predictions of the climate feedback from water vapor.

In other words, if we are after a cause (or causes) for the temperature increase during the period in question, the presence or absence of aerosols from volcanic eruptions is beside the point, because they can not explain any increase in temperatures that occurred prior to any cooling effect they might have had.

«After the maximum cooling for low - latitude eruptions the temperature relaxes back toward the initial state...» Get it?

If not corrected for the above influence, it will show too much cooling after major eruptions, while the reconstruction of Moberg has a reduced impact of tree rings vs. other proxies, thus is less influenced by them.

Some longer - term effects may remain after several consecutive eruptions, but even then, the 0.1 K cooling by volcanic eruptions over the past 600 years (0.3 K modeled over the past 100 years, see fig. 1 on this page) seems rather high...

But they also start to wonder why surface cooling is ``... clearly documented after some eruptions (for example, Gunung Agung, Bali, in 1963) but not others — for example, El Chichon, Mexico, in 1982...» Well, I had to see what that meant.

The models successfully predicted the climatic response after the eruption, a cooling influence that lasted a couple of years.

For severla months after the eruption the world had unusually cool weather, the distinctive red sunsets and prolonged twilight all due to the spread of particles through the air.

For instance, after the 1991 eruption of Mount Pinatubo in the Philippines, scientists noticed the cloud created by the volcano that circled the globe reflected about 10 pe... rcent of the earth's sunlight from 1991 to 1993, cooling the earth by 1 degree for that period.

After a large volcanic eruption, the layer of sulfate aerosols in the stratosphere gets thicker, and we see, in the historic record, that the Earth cools down in response.

Volcanic activity was high during this period of history, and we know from modern studies of volcanism that eruptions can have strong cooling effects on the climate for several years after an eruption.

He writes: I say this is a result of the action of climate phenomena that oppose the cooling... if my theory were correct, we should see a volcanic signal in some other part of the climate system involved in governing the temperature... I should see an increase in the heat contained in the Pacific Ocean after the eruptions Thing is, El Ninos release heat from the ocean, they don't store heat.

In fact, the rate of change of CO2 levels actually drops slightly after a volcanic eruption, possibly due to the cooling effect of aerosols.

In effect, these particles — whether aerosols or kitchen table salt — could act like natural aerosols that cool the planet after a volcanic eruption.

But the expected acceleration due to climate change is likely hidden in the satellite record because of a happenstance of timing: The record began soon after the Pinatubo eruption, which temporarily cooled the planet, causing sea levels to drop.»

As the gas cloud reached its maximum size and concentration a year after the eruption, the strongest effect of the cooling was felt.

The Sulfate cooling mechanism is also evidenced whenever there is a high ejecta mass volcanic eruption, which causes a measurable cooling effect, for about 3 years after an eruption; until the sulfate particulate aerosols diminish in the atmosphere to the point that they become negligible.

The short - term variations are dominated by ENSO but also can be influenced by large tropical volcanic eruptions (such as occurred in 1963, 1982 and, markedly, 1991), so the years after those eruptions are anomalously cool.

Third: There was no cooling in the 1920s; in fact that was the start of a multidecadal warming trend that lasted until just after World War II (followed by a brief cooling trend, possibly due to increased aerosols dimming incoming sunlight together with some pretty big volcanic eruptions which did the same thing).
