Sentences with phrase «of small volcanic eruptions»

Possible explanations advanced for the slowdown include the effect of small volcanic eruptions, the absorption of extra heat by the oceanic depths and the juxtaposition of two natural ocean cycles.

For example, a recent slowing in the rate of surface air temperature rise appears to be related to cyclic changes in the oceans and in the sun's energy output, as well as a series of small volcanic eruptions and other factors.

2) There are errors in the assumed forcings, such as: a) AR5 let stratospheric aerosol concentration go to zero after 2000 (a sure way to prod the models into higher predictions), but it actually increased for the next 10 years «probably due to a large number of small volcanic eruptions».

Some research has tied it to a series of small volcanic eruptions around the globe while other findings have linked it to the changes in winds and ocean circulation.

There have been plenty of smaller volcanic eruptions in recent years, such as the continuously erupting Soufriere Hills on Montserrat and Tavurvur on Papua New Guinea, which may have exploded enough SO2 into the atmosphere.

They can be as small as a grain of salt, but tiny crystals that form deep in volcanoes may be the key for advance warnings before volcanic eruptions.

In a new study, an international team of scientists claim that the most powerful volcanic eruptions, dubbed «super-eruptions», are triggered by a slow and steady drip feed of magma from large reservoirs deep within Earth's crust into smaller reservoirs closer to the surface.

I won't argue that our added gases may contribute to the warming to some very, very small degree, but keep in mind, the ash plume from a good volcanic eruption such as the last big Pinatubo eruption eclipses into insignificants the amount of pollutants added to the atmosphere by human activity.

Last summer, we found small pieces of volcanic glass in a cave that might be from an eruption that occurred in Indonesia nearly 70,000 years ago.

The cause of this relatively short lived cooling (it was not a true «ice age») is not fully known, but the sun could have been cooler, there may have been more volcanic eruptions, there is a small but persistent cooling trend due to orbital cycles (as explained above).

Hundreds of small tremors have rattled the mountain this week, causing almost 10,000 people to leave their homes as of Friday over fears of a volcanic eruption.

It has long been suspected that the low solar activity during the Maunder Minimum was one of the causes of the Little Ice Age, although other factors like a small drop in greenhouse gas concentrations around 1600 and strong volcanic eruptions during that time likely played a role as well.

I won't argue that our added gases may contribute to the warming to some very, very small degree, but keep in mind, the ash plume from a good volcanic eruption such as the last big Pinatubo eruption eclipses into insignificants the amount of pollutants added to the atmosphere by human activity.

The cause of this relatively short lived cooling (it was not a true «ice age») is not fully known, but the sun could have been cooler, there may have been more volcanic eruptions, there is a small but persistent cooling trend due to orbital cycles (as explained above).

A submarine landslide might release a Gigaton of carbon as methane (Archer, 2007), but the radiative effect of that would be small, about equal in magnitude (but opposite in sign) to the radiative forcing from a volcanic eruption.

In Carter's words, the chances of an earthquake there «are small and of a volcanic eruption almost zero.»

This reminds me of the time I mixed uncorrected radiocarbon dates with corrected ones, and got a bit skewed distribution of volcanic events, though I tried to correct for observational bias on earlier and smaller eruptions.

And a conclusion; «There is very high confidence that industrial era natural forcing is a small fraction of the anthropogenic forcing except for brief periods following large volcanic eruptions.»

Scientists have considered a number of theories: small differences in solar radiation; volcanic eruptions that spewed sun - blocking ash and gases into the atmosphere; or pollution from factories, power plants, and tailpipes, particularly in Asia.

Volcanic eruptions, even small and moderate ones, might counter some of the effects of global warming, new research suggests.

Small volcanic eruptions account for part of the global warming slowdown since 2000, a new study suggests.

The answer is that CO2 is only one of several factors that influence temperature, such as volcanic eruptions, solar variability, sulfur dioxide emissions (see Figure 1), and small changes in the earth's orbit.

Although only a small fraction of this vast volcanic terrain has been visually surveyed or sampled, the available evidence suggests that explosive eruptions are rare on mid-ocean ridges, particularly at depths below the critical point for seawater (3,000 m) 1.

While the biggest volcanic eruptions — including large igneous provinces like the Siberian Traps — are known to be linked to climate upheaval and even mass extinctions, emerging work shows that under the right conditions, smaller eruptions or series of eruptions can also affect climate.

«Because the effects of volcanic eruptions and of ENSO are very short - term and that of solar variability very small, none of these factors can be expected to exert a significant influence on the continuation of global warming over the coming decades.

While a smaller volcanic eruption was factored in in 1995, it was nothing near the size of the impact of Pinatubo, either in magnitude of negative forcing or duration.

Large volcanic eruptions increase the number of small particles in the stratosphere that reflect sunlight, leading to short - term surface cooling lasting typically two to three years, followed by a slow recovery.

While volcanic eruptions surely warmed the ocean in the immediate vicinity of the eruptions, the amount of heat they produced compared to the large volume of the Arctic Ocean is small.

Assuming 1 % hydrate by pore water volume were released on average from the slide volume, you get a methane release of about 0.8 Gton of C. Even if all of the hydrate made it to the atmosphere, it would have had a smaller climate impact than a volcanic eruption (I calculated the methane impact on the radiative budget here).
