Reductions in sea ice in the Arctic and Antarctica Cause could alter the seasonal distributions, ranges, patterns, nutritional status, reproductive success, and ultimately the abundance of marine mammals Patient . [ 2IPCCBIODIVERSITE 0 SB GC 04/11/2012 ]

While the regional patterns of future climate change are poorly known, it is clear that the altered patterns of radiative forcing associated with anthropogenic emissions Cause will alter regional climates Patient noticeably Degree , and will have different effects on climate conditions in different regions. [ 13IPCCSTABILISATIONDESGAZ 0 SB GC 04/11/2012 ]

Human activities (primarily the burning of fossil fuels and changes in land use and land cover) are increasing the atmospheric concentrations of greenhouse gases , which Cause alter radiative balances Patient and tend to warm the atmosphere, and, in some regions, aerosols - which have an opposite effect on radiative balances and tend to cool the atmosphere. [ 7IPCCREGION 0 SB GC MCLH 04/11/2012 ]

Projected changes in climate during the 21st century Cause could alter the distribution of antelope species Patient . [ 2IPCCBIODIVERSITE 0 SB GC 04/11/2012 ]

Changes in the global distribution of food production Cause , for instance, will alter traditional food trade patterns Patient . [ 5CANADAICC 0 SB GC 04/11/2012 ]

Emissions of greenhouse gases and aerosols due to human activities Cause continue to alter the atmosphere Patient in ways that are expected to affect the climate Manner . [ 11IPCCBILAN2001 0 SB GC 04/11/2012 ]

Increased temperatures Cause will alter thermal cycles of lakes and solubility of oxygen and other materials Patient , and thus affect ecosystem structure and function. [ 2IPCCBIODIVERSITE 0 SB GC 04/11/2012 ]

Other natural causes of climate change include variations in ocean currents ( which Cause can alter the distribution of heat and precipitation Patient ) and large eruptions of volcanoes (which can sporadically increase the concentration of atmospheric particles, blocking out more sunlight). [ 6CANADAQFP 0 SB GC MCLH 04/11/2012 ]

In general, mechanisms of climate change Cause alter the amount of energy stored by the climate system and in particular the atmosphere Patient . [ ENCY 0 SB GC 04/11/2012 ]

Climate warming Cause is likely to also alter husbandry practices Patient . [ 2IPCCBIODIVERSITE 0 SB GC 04/11/2012 ]

Climate change Cause is anticipated to alter the hydrological cycle Patient and is unlikely to relieve the limitations placed by water scarcity upon the region. [ 7IPCCREGION 0 SB GC 04/11/2012 ]

Major causes of climate change involve any process that Cause can alter the global energy balance, and the energy flows within the climate system Patient . [ ENCY 0 SB GC 04/11/2012 ]

Moreover, changes in wind direction caused by uneven warming of the Earth 's climate Cause may also alter where acid rain is deposited Patient . [ 5CANADAICC 0 SB GC 04/11/2012 ]

Changes in solar irradiance Cause , mainly in the ultraviolet (UV), lead to photochemically-induced ozone changes and, hence, alter the stratospheric heating rates Patient , which can alter the tropospheric circulation. [ 11IPCCBILAN2001 0 SB GC 04/11/2012 ]

Most notable among these are increases in the atmospheric concentrations of greenhouse gases and aerosols (microscopic airborne particles or droplets) and variations in solar activity , both of which Cause can alter the Earth 's radiation budget and hence climate Patient . [ 11IPCCBILAN2001 0 SB GC 04/11/2012 ]

These aerosols Agent , in addition to directly reflecting or absorbing sunlight, can alter cloud processes Patient and have significant impacts on regional climates. [ 6CANADAQFP 0 SB GC 04/11/2012 ]

These gases and particles Agent alter the concentration of atmospheric greenhouse gases Patient , including carbon dioxide (CO2), ozone (O3), and methane (CH4); trigger formation of condensation trails (contrails); and may increase cirrus cloudiness - all of which contribute to climate change (see Box on page 4).
