Because of large natural variability, the first approach results in an outcome suggesting that it is appropriate to conclude that there is no increase in
precipitation by human influences, although the correct interpretation is that there is simply not enough evidence (not a long enough time series).
Not exact matches
«The three papers come to perhaps different numbers, but we're all within uncertainty ranges, well within them, and lends confidence to the statement that there was a significant
human influence on the amount of
precipitation that was produced
by Hurricane Harvey,» he said.
Ongoing climate change caused
by human influences will alter the nature of how rain and snow falls; areas that are prone to dry conditions will receive their
precipitation in narrower windows of time.
This is addressed
by evaluating change in global or large - scale patterns in the frequency or intensity of extremes (e.g., observed widespread intensification of
precipitation extremes attributed to
human influence, increase in frequency and intensity of hot extremes) and
by event attribution methods.
the attribution of a specific heavy
precipitation event to
human - caused GHG's is not an extra development in science that is needed to add to the burden of proof regarding the
human influence on climate already provided
by the current scientific evidence.»
For instance: in support of «temperatures and causality» he cites a paper
by Zhang et al on «Detection of
human influence on twentieth century
precipitation trends».
There is little evidence for a
human influence on
precipitation deficits, but a lot of evidence for a
human fingerprint on surface soil moisture deficits — starting with increased evapotranspiration caused
by higher temperatures.
Even for a particular impact such as
human health, temperature and
precipitation both play important roles
by influencing malnutrition, vector borne diseases, etc. (Campbell - Lendrum and Woodruff 2007).
