No formal attribution studies for changes in drought severity in North America have been attempted.
It is well established through
formal attribution studies that the global warming of the past 50 years is due primarily to human - induced increases in heat - trapping gases.
«
Formal attribution studies now suggest that it is likely that anthropogenic forcing has contributed to the observed warming of the upper several hundred metres of the global ocean during the latter half of the 20th century -LCB- 5.2, 9.5 -RCB-»
Attribution for these phenomena based on expert judgment rather than
formal attribution studies.»
The understanding of the physics of greenhouse gases and the accumulation of evidence for GHG - driven climate change is now overwhelming — and much of that information has not yet made it into
formal attribution studies — thus scientists on the whole are more sure of the attribution than is reflected in those papers.
«Chief among these,» wrote Mann, «is the notion that just because somebody hasn't done
a formal attribution study of a particular event, that event somehow must not have been influenced by climate change.»

«Since the AR4, there is some new limited direct evidence for an anthropogenic influence on extreme precipitation, including a
formal detection and
attribution study and indirect evidence that extreme precipitation would be expected to have increased given the evidence of anthropogenic influence on various aspects of the global hydrological cycle and high confidence that the intensity of extreme precipitation events will increase with warming, at a rate well exceeding that of the mean precipitation..
An asterisk in the column headed «D' indicates that
formal detection and
attribution studies were used, along with expert judgement, to assess the likelihood of a discernible human influence.
This
study addresses the challenge by undertaking a
formal detection and
attribution analysis of SCE changes based on several observational datasets with different structural characteristics, in order to account for the substantial observational uncertainty.

studies suggest that late 20th - century warming is much more likely to be anthropogenic than natural in origin, a finding which is confirmed by
studies relying on
formal detection and
attribution methods (Section 9.4.1.4).»
