Sentences with phrase «less volcanic activity»

So with less volcanic activity, you'd expect to see more warming.

So, for example, if we go through a period of relative higher solar output, and less volcanic activity, relatively less cloudiness, and higher greenhouse gas levels, these would all tend to increase ocean heat content.

It has now become clear to scientists that the Medieval Warm Period occurred during a time which had higher than average solar radiation and less volcanic activity (both resulting in warming).

If the cooling from 1940 to 1975 was due (mainly) to aerosols, I would expect then that we would still be experiencing cooling, roughly equal to the 1960s, but certainly not warming faster than the pre-1940 era (when there was less volcanic activity, more active sun etc).

Not exact matches

This may have been triggered by a 250 - million - year lull in volcanic activity, which would have meant less carbon dioxide being pumped into the atmosphere, and a reduced greenhouse effect.

Faster sea floor spreading, presumably associated with more volcanic activity at subduction zones, and / or other increases in volcanic activity or geologic outgassing, or faster oxidation of exposed fossil organic C (as in shales)-- greater geologic CO2 emissions (I think another way of looking at the inorganic part is that any given region of sea floor has less time to accumulate carbonate minerals from chemical weathering, so that C reservoir could shrink while others, including the atmosphere, can grow).

Lava tubes, or volcanic pipes are volcanic caves, usually in the form of tunnels formed within lava flows more or less fluid reogenética duration of the activity.

Human induced trend has two components, namely (a) greenhouse effect [this includes global and local / regional component] and (b) non-greenhouse effect [local / regional component]-- according to IPCC (a) is more than half of global average temperature anomaly wherein it also includes component of volcanic activities, etc that comes under greenhouse effect; and (b) contribution is less than half — ecological changes component but this is biased positive side by urban - heat - island effect component as the met network are concentrated in urban areas and rural - cold - island effect is biased negative side as the met stations are sparsely distributed though rural area is more than double to urban area.

I've always flatly denied that GW has any impact on EARTHQUAKES and VOLCANIC ACTIVITY to those little people with even less knowledge than myself.

12 * ICE AGES: More elliptical orbit causes less sunlight to reach Earth — results in ice ages (100,000 yr cycles) * VOLCANIC ACTIVITY: Release ash and aerosols into the atmosphere Reflects sun rays causing cooler temps * SOLAR ENERGY: Cause short term changes Less solar energy can cause small ice less sunlight to reach Earth — results in ice ages (100,000 yr cycles) * VOLCANIC ACTIVITY: Release ash and aerosols into the atmosphere Reflects sun rays causing cooler temps * SOLAR ENERGY: Cause short term changes Less solar energy can cause small ice Less solar energy can cause small ice ages

The various kinds of evidence examined by the panel suggest that the troposphere actually may have warmed much less rapidly than the surface from 1979 into the late 1990s, due both to natural causes (e.g., the sequence of volcanic eruptions that occurred within this particular 20 - year period) and human activities (e.g., the cooling of the upper part of the troposphere resulting from ozone depletion in the stratosphere).

weaker solar irradiance weaker solar wind increase in cosmic rays increase in volcanic activity decrease in ocean heat content a more meridional atmospheric circulation more La Ninas, less El Ninos cold Pdo / Amo

Increasing galactic cosmic rays being a main factor for major volcanic activity to increase and global cloud coverage to increase while less EUV light should result in a more meridional atmospheric circulation which would also result in more clouds and also greater snow coverage.

Doubling volcanic activity would accordingly add less than one part per thousand to the existing radiative forcing from man made CO2.

1) Positively: Clouds and cloud formation, mostly 2) Positively: Volcanic activities 3) Positively: more % Water vapor in the atmosphere, 4) Positively or negatively, but % more or less constant: Oxygen, trace gases: ozone, methane & CO2 mostly.
