The stadium wave holds promise in putting into perspective numerous observations of climate behavior, such as regional patterns of decadal variability in drought and hurricane activity, the researchers say, but a complete understanding of past climate variability and projections of future climate change requires integrating the stadium - wave signal with external climate forcing from the sun, volcanoes and anthropogenic forcing.
This is also observed in the changing activity of the Sun.
It seems that in terms of the total amount of energy coming from the sun there is only a very small variation due to the changing level of solar activity during a single cycle.
If it is true that the sun's activity is of great significance in determining the earth's climate, this reduced solar activity could work in the opposite direction to climate change caused by humans.
