Benca irradiated 18 - inch - tall, bonsai - like pines with UV - B dosages up to 13 times stronger than on Earth today, simulating the effects of ozone depletion caused by immense volcanic eruptions that occurred at the end of the Permian Period.

Infrasound signals can remain strong as they travel over large distances, making them useful for pinpointing the location and size of events such as nuclear explosions, meteorite strikes, volcanic eruptions and sometimes earthquake ruptures.

In particular, eruptions such the Timanfaya's in Lanzarote ─ one of the strongest in the country due its duration until 1736 and the amount of thrown material ─ and Tambora's ─ one of the biggest volcanic episodes, which led to a «year without summer» in 1816 ─ released big amounts of iron that altered the chemical composition of the annual Pyrenean tree rings.

Molten rock (or magma) has a strong influence on our planet and its inhabitants, causing destructive volcanic eruptions and generating some of the giant mineral deposits.

So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

A volcanic eruption or sudden, strong La Niña are two of the only likely factors that could put a damper on the U.K. Met Office projections.

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.

So when you put cooling natural volcanic eruptions in 1982 and 1991 together with a warming natural strong El Nino in 1998 you get a slight upward tilt to the global temperature graph, but it's entirely due to the dominace of natural events.

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.

I excluded years which were strongly influenced by the El Chichón (1983 — 1985) and Mount Pinatubo (1992 — 1994) volcanic eruptions (because large eruptions release particulates into the atmosphere which cause a strong short - term cooling), and looked at the temperature trends in each of the three categories (Figure 1).

The explosive volcanic eruption of El Chichon may have counteracted the Super El Nino of 1982/83, but the 1986/87/88 El Nino was strong enough to cause upward shifts in the SST and TLT anomalies of the Mid-To-High Latitudes of the Northern Hemisphere, and the SST anomalies of the East Indian and West Pacific Oceans, similar to the shifts caused by the 1997/98 El Nino illustrated in this post.

In contrast, global avg temperature data do show that after a dip (e.g. due to a strong volcanic eruption), the data go back to the level that they would have had in the absence of the dip.

Then I constructed an XY plot of temperature vs. forcings by year (with volcanic eruptions removed), fitted a line and got a strong linear relationship (R = 0.98) with a gradient of 0.32 C per watt / sq m and no sign of any change with time.
