Collins's research looks at how desert ecosystems respond to climate variability, and he also has experiments simulating
droughts that are predicted
under global warming.
Under BAU [Business As Usual], agriculture and civilization will collapse some time between 2050 and 2055 due to
drought / desertification caused by GW [
Global Warming].
«We also present a set of
global vulnerability drivers that are known with high confidence: (1)
droughts eventually occur everywhere; (2)
warming produces hotter
droughts; (3) atmospheric moisture demand increases nonlinearly with temperature during
drought; (4) mortality can occur faster in hotter
drought, consistent with fundamental physiology; (5) shorter
droughts occur more frequently than longer
droughts and can become lethal
under warming, increasing the frequency of lethal
drought nonlinearly; and (6) mortality happens rapidly relative to growth intervals needed for forest recovery.
Climate projections indicate that the likelihood of more severe
droughts, such as the one we're observing, increases
under global warming.

Drought Under Global Warming for instance), floods, general bunching of rainfall into briefer, heavier rains, and how deep are Canadian soils?
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.
Speaking in Anchorage, AK on Monday, Obama warned that without quick action to slow or reverse
global warming, «entire nations will find themselves
