The global climate Patient has shifted and varied for billions of year, perhaps since the Earth first had an atmosphere. [ ENCY 0 MCLH 01/07/2013 ]

Some systems are more vulnerable to changes in regional climate than others - e.g., human systems are more adaptive, hence on average less vulnerable, than natural systems; forested systems require longer periods than grassland systems to establish themselves and hence are less likely to be able to migrate to new locations with suitable conditions, as temperature and precipitation patterns Patient shift. [ 13IPCCSTABILISATIONDESGAZ 0 MCLH 01/07/2013 ]

As weather patterns Patient shift in the years following the collapse, it is not clear what type of weather future years will bring. [ RAPPORTPENTAGONE 0 MCLH 03/08/2013 ]

The elevational range of some birds in the Costa Rican tropical cloud forest Patient may also be shifting. [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]

More recently, scientists realised that the changes in the amount of energy received by the Earth from the Sun as a result of orbital variations would not be enough to explain the significant Degree shifts in climate Patient between Ice Age and interglacial conditions on Earth Duration . [ ENCY 0 MCLH 01/07/2013 ]

Projected future climate change and sea-level rise Cause will affect shifts in species composition and competition Patient . [ 3IPCCCONSEQUENCE 0 MCLH 01/07/2013 ]

However, species have varying tolerance ranges for temperature and thus shifts in temperature Patient can produce changes in species composition that can affect the overall productivity of individual freshwater ecosystems and their utility to humans. [ 3IPCCBIODIVERSITE 0 MCLH 01/07/2013 ]

These maps illustrate that, at a regional scale, the national trends to warmer climates have been modified by shifts in seasonal wind patterns Patient . [ 5CANADAICC 0 MCLH 03/08/2013 ]

Climate change is a long- term Duration shift or alteration in the climate of a specific location, a region or the entire planet Patient . [ 6CANADAQFP 0 MCLH 01/07/2013 ]

The longer the extremes persist, however, the less adequate these explanations become and the more we must consider the possibility of a long- term Duration shift in climate behaviour Patient . [ 2CANADACCD9801 0 MCLH 01/07/2013 ]

Any shift in average climate Patient will almost inevitably result in a change in the frequency of extreme events. [ ENCY 0 MCLH 01/07/2013 ]

Yet, remarkably, reconstructions of past temperature patterns suggest that these natural fluctuations Cause , though sufficient to cause tremendous Degree shifts in global ecosystems Patient , have for many millions of years remained within a relatively narrow margin needed to support terrestrial life. [ 5CANADAICC 0 MCLH 01/07/2013 ]

Grid point models of the terrestrial biosphere have been used to assess the effect on the net biosphere-atmosphere CO2 flux of hypothetical (or GCM-generated) changes in temperature and/or atmospheric CO2 concentration, but generally without allowing for shifts in the ecosystem Patient type at a given grid point as climate changes. [ 10IPCCMODELE 0 MCLH 01/07/2013 ]

In temperate Asia, species Agent are likely to shift polewards Destination and boreal forest species projected to show large shifts (up to 400 km) in the next 50 years. [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]

Sea-level rise will affect mangrove ecosystems by eliminating their present habitats and creating new tidally inundated areas to which Destination some mangrove species Agent may shift. [ 3IPCCCONSEQUENCE 0 MCLH 03/08/2013 ]

A study of 35 non-migratory butterflies in Europe showed that over 60 % Agent shifted north Destination by 35-240 km Value over the 20th century Duration . [ 2IPCCBIODIVERSITE 0 MCLH 03/08/2013 ]
