The resulting mapped index
showed drier regions in the East Cascades and Blue Mountains becoming more vulnerable to mortality under recent climate conditions.

Also of major interest, the team notes, is that the sudden collapse of the nearby Guge kingdom of western Tibet (ruins
shown) around 1620 C.E. — which had previously been ascribed to military conflicts — occurred near the end of the
region's
driest 3 decades in the past 5700 years.
The 28 models used by the team
showed agreement in many parts of the world on the change in the number of
dry days those
regions will receive.
Professor Kug notes that further research is needed to obtain a general conclusion on the matter, but this research delivers important implications for climate adaptation because the analysis
shows that if current warming trends continue, it is feasible to conclude that the ecosystems in
regions affected by the anomalous climate will suffer greater damages due to the cold and
dry spells.
Earth's wet
regions are getting wetter and
dry regions are getting
drier, but it is happening at a slower rate than previously thought, research
shows.
Using climate models at the Laboratoire de Météorologie Dynamique, François Forget (CNRS) and Martin Turbet (UPMC)
show that, with a cold climate and an atmosphere denser than it is today, ice accumulated at around latitude 25 ° S, in
regions corresponding to the sources of now
dry river beds.
The red
region shows the habitable zone as extended inward for
dry planets, with minimal surface water, a low water - vapor atmospheric abundance, and low atmospheric relative humidity and hence a smaller greenhouse effect.
One such valley, Margaritifer Sinus, would have received less rain than some other areas due to the Tharsis bulge causing
drier air to flow over that
region, yet
shows evidence of large amounts of water having flowed there.
This new research
shows the first clear evidence of the long - term effects of pollution particles on cloud height and thickness, and how those changes both reduce precipitation in
dry regions and increase precipitation in wet
regions.
A study has
shown that the
region's climate is much like that of France's Bordeaux: frost - free, with high rainfall in winter and warm,
dry summers.
(The images above, from the paper,
show how investments in water storage and other measures helped restore vegetation in a
dry region in Niger.)
does not
show the
drying trend
shown in other
regions of the world over the last 30 years or so.
The researchers chose to tackle the
region in part because previous, coarser - resolution models had
shown that this area would be
drying out, a prediction that has been borne out in the droughts and wildfires of recent years.
Observational records
show that anthropogenic - influenced climate change has already had a profound impact on global and U.S. warm season climate over the past 30 years, and there is increasing contrast between geographic
regions that are climatologically wet and
dry - the hypothesis that the «wet gets wetter,
dry gets
drier» is seen in a new paper by Chang et al..
To do so, you'd need a study such as mine which
shows water vapour cools and more moist
regions have lower mean daily maximum and minimum temperatures than
drier regions at similar latitudes and altitudes.
DES MOINES (AP)-- Warmer and wetter weather in large swaths of the country have helped farmers grow corn, soybeans and other crops in some
regions that only a few decades ago were too
dry or cold, experts who are studying the change said... The change is due in part to a 7 % increase in average U.S. rainfall in the past 50 years, said Jay Lawrimore, chief of climatic analysis for the Asheville, N.C. - based National Climactic Data Center... Brad Rippey, a U.S. Department of Agriculture meteorologist, said warming temperatures have made a big difference for crops such as corn and soybeans... For example, data from the National Agricultural Statistics Service
show that in 1980, about 210,000 soybean acres were planted in North Dakota.
In this map from the study published in Science Advances,
regions shown in green and blue will likely get wetter as the planet warms, and
regions show in brown shades will get
drier.
The results obtained by Donat and his team suggest that both annual precipitation and extreme precipitation increased by 1 — 2 % per decade in
dry regions, with wet areas
showing similar increases in the extent of extreme precipitation and smaller increases for annual totals.
The averages for the last 12 months
show dry conditions over most
regions within a large belt stretching across parts of both Europe and Asia, with below average precipitation and soil moisture and much below average relative humidity, starting in south - western Europe and ending near Japan.
This
drying is not accompanied by an appreciable reduction in precipitation, as
shown below for four European
regions.
A recent study
shows that rains and mountain snows are
drying up, and many experts already believe the
region has entered a multidecade megadrought.
Some analyses of long - term historical weather data for the
region show a
drying trend, and others no change in rainfall at all (Hulme et al. 2001; Christensen et al. 2007; Funk et al. 2008; Williams and Funk 2011).
The findings of a new study, appearing in Science,
show that there is a broad consensus amongst climate models that this
region will
dry significantly in the 21st Century and that the transition to a more arid climate may already be underway.
