Scientists have long explained that winter and record cold snaps will not disappear as a result of climate change, and that cold spikes may get worse as a result of shifting weather
patterns under global warming.
Not exact matches
The authors of the study said the change could be temporary, given the short span of observations, but it matches a slight but steady
warming trend in the affected ocean regions and also matches a
pattern scientists have predicted would occur
under human - caused
global warming.
In other words,
under solar or anthropogenic influence the changes in mean climate values, such as the
global temperature, are less important than increased duration of certain climate
patterns associated say with cold conditions in some regions and
warm conditions in the other regions
But the role of climate change in causing the drought itself is unclear — the more immediate cause is an intermittent weather
pattern called La Niña, and research is still
under way on whether that cycle is being altered or intensified by
global warming, as some researchers suspect.
An alternative approach uses simple climate model projections of
global warming under stabilisation to scale AOGCM
patterns of climate change assuming unmitigated emissions, and then uses the resulting scenarios to assess regional impacts (e.g., Bakkenes et al., 2006).
