Sentences with phrase «while volcanic activity»

But solar output fell, while volcanic activity and aerosol pollution rose.

Not exact matches

Volcanoes which are persistently active and emit a strong plume, while at the same time have low enough volcanic activity, are the perfect candidates to study.

Volcanic activity at Mt. Songak was limited hydro volcanic activity out of which a great deal of volcanic ash was released while it is evident that Sangchang - ri was a dynamic active volcano out of which lava was spewed and then flowed down in all directions along the inlanVolcanic activity at Mt.

One just included the effective influence on temperatures from manmade forces (including greenhouse gases and aerosols, which tend to have a cooling effect), while the second included both manmade and natural ones (including volcanic activity and solar radiation).

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).

``... While [ozone depleting substance] ODS levels remain high, a large stratospheric sulfuric aerosol enhancement due to a major volcanic eruption or geoengineering activities would result in a substantial chemical depletion of ozone over much of the globe.»

It is to be noted here that there is no necessary contradiction between forecast expectations of (a) some renewed (or continuation of) slight cooling of world climate for a few decades to come, e.g., from volcanic or solar activity variations; (b) an abrupt warming due to the effect of increasing carbon dioxide, lasting some centuries until fossil fuels are exhausted and a while thereafter; and this followed in turn by (c) a glaciation lasting (like the previous ones) for many thousands of 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.

The you could focus on the ocean and avoid the land and polar amplification noise in the surface temperature see that while the NH oceans from 45N to 65N recovered quickly from the early 1900 volcanic activity, the equator and SH lagged that recovery by ~ 20 years.

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.

Precession / obliquity — Precession very favorable while obliquity is lessening and becoming more favorable as compared to the Holocene Optimum period of time and this is why I think the global temperatures in general have been on a decline overall since the Holocene optimum however with fits and starts due to solar activity changes / volcanic activity and enso superimposed upon this general trend.

Alex's simple model is worthy of further refinement to accommodate the influence of solar fluctuations, volcanic activity, changes in GHG and the influence of clouds, My hunch is that while these factors on their own would have a relatively minor effect on climate trends, they may impact much more when their incidence is synchronised.

To identify the effects of human activity on temperature, we simulate the model (estimation sample 1960 — 1998) with post 1998 values of solar insolation, SOI, and volcanic sulfates held at their 1998 level while allowing greenhouse gas concentrations and sulfur emissions to evolve as observed.

It kinda looks like the LIA was caused by a series of volcanic events and the ~ 60 year «oscillation» inspired by more volcanic activity while the globe was recovering from the LIA.
