Sentences with phrase «anthropogenic radiation change»

From a leaked draft of the IPCC's Fifth Assessment Report (AR5), the IPCC reports a global temperature rise of 0.89 °C ** from 1901 - 2012 and a total anthropogenic radiation change of 2.29 W / m2.

Not exact matches

While natural global warming during the ice ages was initiated by increased solar radiation caused by cyclic changes to Earth's orbital parameters, there is no evident mechanism for correcting Anthropogenic Global Warming over the next several centuries.

This is the portion of temperature change that is imposed on the ocean - atmosphere - land system from the outside and it includes contributions from anthropogenic increases in greenhouse gasses, aerosols, and land - use change as well as changes in solar radiation and volcanic aerosols.

By Amber Bentley (Aged 11) In just 16 pages, this wonderful book covers the structure of the atmosphere, solar radiation, the water cycle, clouds, fronts, convection, air pressure, air masses, the global atmospheric circulation, making weather observations, forecasting, synoptic charts, hurricanes, regional climate, palaeoclimates and anthropogenic climate change.

It is not clear how much is the actual anthropogenic contribution to a changed radiation budget (again, even the sign of the anthropogenic effect is not known).

As such, it can not capture the slow - down in net anthropogenic forcings that allows the effects of declining solar radiation and changes from El Nino or La Nina to dominate the 1999 — 2008 period.

Theoretical and Applied Climatology covers climate modeling, climatic changes and climate forecasting, micro - to mesoclimate, applied meteorology as in agro - and forestmeteorology, biometeorology, building meteorology and atmospheric radiation problems as they relate to the biosphere; effects of anthropogenic and natural aerosols or gaseous trace constituents; hardware and software elements of meteorological measurements, including techniques of remote sensing, among other topics of current interest.

We know there are effects from land use change and we know we have added to atmospheric backscatter of solar radiation from particulates (sulfate aerosols, dust from agriculture...) but we are no longer certain of the net sign of anthropogenic temperature change.

Aerosols of anthropogenic origin are responsible for a radiative forcing (RF) of climate change through their interaction with radiation, and also as a result of their interaction with clouds.

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).

These include other anthropogenic factors such as increased industrial aerosols and ozone depletion, as well as natural changes in solar radiation and volcanic aerosols, and the cycle of El Niño and La Niña events.

The 2007 Fourth Assessment Report compiled by the IPCC (AR4) noted that «changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system», and concluded that «increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century».
