Sentences with phrase «volcanic gases up»

Explosive eruptions, however, can send volcanic gases up into the stratosphere, where they «greatly affect the spectrum of the planet,» Misra said.

Not exact matches

«If you went back to 1850 and repeated history» — meaning the same volcanic eruptions, the same solar variability, the same greenhouse gas emissions — «the overall temperature increase would be about the same, but you would end up with somewhat different temperature records due to the inherent randomness in the climate.»

Nutrient - rich ash from an enormous flare - up of volcanic eruptions toward the end of the dinosaurs» reign kicked off a chain of events that led to the formation of shale gas and oil fields from Texas to Montana.

When basalt — a volcanic rock that makes up roughly 70 percent of the earth's surface — is exposed to carbon dioxide and water, a chemical reaction occurs, converting the gas to a chalk - like solid material.

It warned that if a similar eruption occurred, it could send rocks bigger than fist - size up to 8 km (5 miles) from the summit and volcanic gas to a distance of 10 km (6 miles) within three minutes.

After all, on my way up, I've survived a walk through hell, a valley of extreme volcanic activity, belching stinking sulphurous gases.

The other point about volcanic emissions: the majority of the activity is in the oceanic spreading zones, which release carbon into the water, but because it is absorbed by the water, the gas isn't released for some time, sometimes up to 1000 years.

First, while the early 20th century warming was likely predominantly naturally - caused (i.e. low volcanic activity and increasing solar activity), there was also a significant human contribution as greenhouse gas emissions began to ramp up.

««Climate model simulations that consider only natural solar variability and volcanic aerosols since 1750 — omitting observed increases in greenhouse gases — are able to fit the observations of global temperatures only up until about 1950.»

However, there is not compelling evidence that anthropogenic CO2 was sufficient to influence Earth's temperatures prior to 1950, i.e. «Climate model simulations that consider only natural solar variability and volcanic aerosols since 1750 — omitting observed increases in greenhouse gases — are able to fit the observations of global temperatures only up until about 1950.»

One proposal is that volcanic activity releases greenhouse gases that eventually warm the planet back up.

To that you answer if the temperature ever starts to rise, due to say volcanic heat, or upwelling to water's surface, the heat is immediately removed by the power of evaporation as infrared - resonant gases chug heat straight up through the atmospheric mix to belch it out radiatively at higher altitude; while simultaneously dragging other, non-infrared resonant gases upward with them, to also dump THEIR heat radiatively, from a higher position than they would have, had the refrigerative cycle not taken place.
