project, highlighted the climate changes that must have caused this
increase in sediment erosion and transport — «We have climate model simulations of the effect of warming on
rainfall during the PETM event, and they show some changes in the average amounts of
rainfall, but the largest change is how this
rainfall is packaged up — it's concentrated in more rapid, extreme events — larger and bigger storms.»

rainfall is
projected to
increase, as is temperature, both of which lead to more methane emissions, but some models predict a drying out of soils which would reduce said emissions... I guess we'll find out.

rainfall and bountiful growth being a result that will help feed
increasing populations without having to
increase the extent of agricultural lands.

projected increases in the intensities of the strongest storms and
increased rainfall rates
As the model adjusts to these
increases, it indicates
projected changes in temperature,
rainfall, cloudiness, and other climate variables.

projected to experience
increased rainfall — predominantly in the deep tropics — overall changes to island freshwater balance will shift towards greater aridity for over 73 % of the island groups (16 million people) by mid-century.
Scientists expect more intense storms to occur in the Midwest throughout the year, and more precipitation to fall in winter and spring.4 If our carbon emissions continue to rise at current rates, spring
rainfall in Jefferson City is
projected to
increase 25 percent or more by the end of this century.9, 10
Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation
increased during the past century (by up to 20 % in some locations), with much of the
increase driven by intensification of the heaviest
rainfalls.77, 78,79 This tendency towards more intense precipitation events is
projected to continue in the future.80

projected to rise about 1.8 ° F (1 ° C) in the next few decades.3
Rainfall is expected to decline 3 - 5 percent, and evaporation to
increase 2 - 4 percent3 — creating conditions conducive to an environment for
increasing frequency of bushfires.
The report says global climate change is
projected to produce «insufficient water supplies, shifting
rainfall patterns, disruptions to agriculture, human migrations, more failing states,
increased extremism, and even resource wars,» all of which pose an urgent threat that must be addressed in national security policy.
Moderate climate change in the coming decades is
projected to
increase overall yields by 5 - 20 % on agricultural lands that rely of
rainfall, although major challenges are

Increases in
rainfall erosivity by as much as 11 to 22 % by the year 2050 were
projected across the region.
The models are in better agreement when
projecting changes in hurricane precipitation — almost all existing studies
project greater
rainfall rates in hurricanes in a warmer climate, with
projected increases of about 20 % averaged near the center of hurricanes.
Hurricane intensity and
rainfall are
projected to
increase as the climate continues to warm.
The authors assert that the human - caused post-1940s cooling trend and
increase in precipitation dramatically conflict with climate model expectations which
project a human - caused warming trend and decreasing
rainfall with the advent of
increasing GHG emissions.
The two interior sites are
projected to retain the characteristics of a nival regime by mid-century, although streamflow - timing shifts result from
increased mid-winter
rainfall and snowmelt, and earlier freshet onset.

In particular, over NH land, an

projected over much of central and northern Europe due to the
increase in intense precipitation during storm events, suggesting an
increased chance of flooding over Europe and other mid-latitude regions due to more intense
rainfall and snowfall events producing more runoff.
