Sentences with phrase «volcanic influences on the climate»

Bertrand was investigating the effect of solar and volcanic influence on climate and concluded «these are clearly not sufficient to explain the observed 20th century warming and more specifically the warming trend which started at the beginning of the 1970s».

Not exact matches

We already know that climate change has a hold on Earth's surface processes, such as erosion and fluctuations in sea levels... but do surface processes in turn have an influence on volcanic activity?

These results, which you can read all about in the journal Nature Geoscience, reveal the influence of surface processes — largely controlled by climate — on volcanic activity.

We instead conclude that solar forcing probably had a minor effect on Northern Hemisphere climate over the past 1,000 years, while, volcanic eruptions and changes in greenhouse gas concentrations seem to be the most important influence over this period.

Their workings discount natural influences; solar radiation, clouds, volcanic eruptions, ocean currents PDO / AMO as having any real effect on the climate.

Scientists have already speculated that volcanic cycles on land emitting large amounts of carbon dioxide might influence climate; but up to now there was no evidence from submarine volcanoes.

The influence of volcanic activity on the climate is indubitable.

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.

Major volcanic eruptions have a short - term cooling influence on climate due to the particulate haze they cause.

Forster et al. (2007) described four mechanisms by which volcanic forcing influences climate: RF due to aerosol — radiation interaction; differential (vertical or horizontal) heating, producing gradients and changes in circulation; interactions with other modes of circulation, such as El Niño - Southern Oscillation (ENSO); and ozone depletion with its effects on stratospheric heating, which depends on anthropogenic chlorine (stratospheric ozone would increase with a volcanic eruption under low - chlorine conditions).
