OK, so I've seen where warmist cult followers have attempted to blame the japan earthquake on AGW, but considering we should be able to put cause an effect in the right order...
What overall effect will the change in the earths axis have on climate?
Changing the earths obliquity has a greater effect on climate than just shifting the ice sheets an equivalent amount of distance.
Are we standing more straight up and down? This would mean less seasonal variation.
Are we more tilted? This would mean more seasonal variation.
Either has an effect on the relative length of day and night which also effect climate.
There will also be slight changes in albedo as areas covered either by land or ocean are exposed to more or less light depending on the season.
And lastly what minor effect it may have on the jet stream and ocean currents and what minor effect (if any) that would have on overall climate.
All of the effects of a four inch shift will be minor, and likely won't add up to much. but there will be an overall effect.
Quake moved Japan coast 8 feet; shifted Earth's axis - CNN.com
The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis.
"At this point, we know that one GPS station moved (8 feet), and we have seen a map from GSI (Geospatial Information Authority) in Japan showing the pattern of shift over a large area is consistent with about that much shift of the land mass," said Kenneth Hudnut, a geophysicist with the U.S. Geological Survey (USGS).
Reports from the National Institute of Geophysics and Volcanology in Italy estimated the 8.9-magnitude quake shifted the planet on its axis by nearly 4 inches (10 centimeters).
