With regards to his claims on extreme weather, they consulted Andreas Prein of the National Center for Atmospheric Research who said, «This is a false statement since the IPCC AR5 even states in its Summary for Policymakers that «Human influence has been detected -LSB-...]
in changes in some climate extremes».
Projected
changes in climate extremes under different emissions scenarios generally do not strongly diverge in the coming two to three decades, but these signals are relatively small compared to natural climate variability over this time frame.
She will also investigate the combined affects of natural variability and increased greenhouse forcings
on changes in climate extremes throughout the 21st Century.
Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and
in changes in some climate extremes.
The authors review general trends in climate, with particular emphasis on biologically meaningful parameters such as continuous dry days and
changes in climate extremes and forest disturbance patterns.
It also says that human influence has been detected in: warming of the atmosphere and the ocean; changes in the global water cycle; reductions in snow and ice; global mean sea level rise; and
changes in some climate extremes.
Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in
changes in some climate extremes (Figure SPM.6 and Table SPM.1).
Human health impacts have been exacerbated by variations and
changes in climate extremes.

Changes in climate extremes and their impacts on the natural physical environment.
The IPCC's Fifth Assessment Report (Summary for Policymakers) states, «Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in
changes in some climate extremes.
«Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in
changes in some climate extremes,» the report said.
