Our analysis provides a critical local look at changes for two important climate variables, precipitation and temperature.

For the hydrological modelling of the Thames river catchment done at CEH we showed that the changes in atmospheric circulation and precipitation caused higher peak 30 - day river flow, while flood risk mapping revealed a small increase in flood risk for properties in the Thames catchment.

ACPI assumes a 1 percent annual increase in the rate of greenhouse gas concentrations through the year 2100, for little change in precipitation and an average temperature increase of 1.5 to 2 degrees centigrade at least through the middle of 21st century.

To see how winter precipitation is changing, we looked at states that all see notable amounts of snow (sorry, Florida).

Data analyses have found an increase of drought intensity at many locations [130]--[131] The magnitude of change depends on the drought index employed [132], but soil moisture provides a good means to separate the effect of shifting seasonal precipitation and confirms an overall drought intensification [37].

Except that GHG forcing + cooling aerosol forcing results in less precipitation globally in general than reduced GHG forcing that produces the same global average temperature, as found in «Climate Change Methadone» elsewhere at RC.

i.e. changes in precipitation, vegetation, deep ocean currents, etc. are at any time as likely to cool as to heat.

-- Projected precipitation and temperature changes imply changes in floods, although overall there is low confidence at the global scale regarding climate - driven changes in magnitude or frequency of river - related flooding, due to limited evidence and because the causes of regional changes are complex.

The water vapor feedback (a generally positive feedback)-- there is an roughly exponential increase in saturation water vapor pressure with increasing temperature, and the relative humidity (at a given vertical level) overall tends not to change a lot globally, though there will be different regional trends associated with shifting precipitation patterns.

While glacier melt contributes water to the region's rivers and streams, retreating glaciers over the next several decades are unlikely to cause significant change in water availability at lower elevations, which depend primarily on monsoon precipitation and snowmelt, the committee said.

Moreover, local heavy precipitation trends may not accurately reflect changing patterns happening at a larger, regional level.

On average in the United States, the amount of rain falling during the heaviest 1 percent of rainstorms has increased nearly 20 percent during the past 50 years — almost three times the rate of increase in total precipitation.4, 5 The Midwest saw an even larger average increase of 31 percent, surpassed only by the Northeast (at 67 percent).4 Scientists attribute the rise in heavy precipitation to climate change that has already occurred over the past half - century.6

At the same time, precipitation patterns are also changing all over the planet; in the Arctic, that means more erratic snowfall.

The slower components of the climate system (e.g. the ocean and biosphere) affect the statistics of climate variables (e.g. precipitation) and since they may feel the influence of their initial state at multi decadal time scales, it is possible that climate changes also depend on the initial state of the climate system (e.g. Collins, 2002; Pielke, 1998).

«We're seeing increasing temperatures and relatively little change in average precipitation, but an increase in the variability and the occurrence of both wet and dry extremes,» said Daniel Swain, an atmospheric scientist at Stanford's School of Earth, Energy & Environmental Sciences and the lead author of a new paper published in Science Advances.

It's interesting to see that the «great European climate step change» which seems to have occurred around 1987 - 1989 isn't very visible in Norwegian temperatures (at least compared to some of your records above, where it is easily visible), but it's clearly visible in the precipitation record.

But Swain and his colleagues wanted to know if that was because there was really little change in precipitation or if there were big changes at either end of the spectrum that balanced each other out when looking at yearly averages.

Scientists already know how climate change is impacting the Western United States — higher temperatures have translated to earlier spring snow melts, precipitation is falling more as rain instead of snow at higher elevations and there's reduced runoff and streamflow.
