Are volcanoes effected by global warming?

Question

im doing my science fair project on it, can you help me

Answer 1

Major volcanic eruptions usually CAUSE global COOLING, like the 1 degree C cooling after Pinatubo and the 1816 'year without a summer' when Tambora erupted in 1815.

Global warming is a human phenomena, and volcanism is not a big contributer and will not change with warming.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest.
(see links below)

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Answer 2

Volcanoes produce much more CO2 than humans could dream of putting into the atmosphere!! The difference is, volcanoes are natural and they have been around since the Earth formed 4.5 Ga. However, humans have only been industrialized for the last 100 years or so and our influence of CO2 is not a natural process.

Our Earth is a very complex system and over a long period of time, the Earth has feedbacks to regulate itself, which is commonly referred to as the Carbonate-Silicate Weathering cycle:
http://www.carleton.edu/departments/geol/DaveSTELLA/Carbon/long_term_carbon.htm

So, volcanoes provide CO2 and other greenhouse gases (such as water vapor, the strongest greenhouse gas on Earth) naturally. However, the main concern with global warming is how much CO2 we are putting into the Earth's atmosphere and how climate will change as a result. The short term changes that humans have made are significant and the long-term effects of the Carbonate-Silicate weathering cycle cannot account for the human influence.

Hope this helps.

Answer 3

Volcanos affect global warming on a very very small scale. Volcanos do produce some greenhouse gasses and do eliminate ozone in the upper atmosphere, however, the effect is minimal. Although volcanos can cause some global cooling, this effect is also very minimal. Every see artist representations of the Jurrassic period with volcanos erupting. Jurassic dinos obviously lived in a tropical or sub-tropic environment yet it was one of the heaviest periods of volcanism in Earths history so volcanos effects on cooling are minimal.

Answer 4

Volcanoes do affect global atmospheric warming, however they do NOT usually get effected by global atmospheric warming.

Answer 5

Global climate change affects the atmosphere, the oceans, anything in the hydrosphere and biosphere. Volcanoes are not affected by climate change.

(P.S. You meant "affected").

Answer 6

volcano's can have lot's of effects on all kinds of weather depends how big they are and where located

Answer 7

Stand near it observe what happens if it effects then yes if no then no
