Could an Earth impact by a large stellar object do just enought damage to change the tilt axis and thus completely change the weather patterns?

The earth has a tilt. Yes it is not perfectly straight up and down with respect to it's orbital plane around the sun. It is slightly tilted. The thing I was wondering about is like this:

Has the earth always been tilted on it's axis at the precise angle it now is and could it be possible that earlier in earth's history, possibly millions of years ago, when an asteroid hit the planet could it have altered the angle of the tilt and if that is true, could a future Near Earth Object hit earth at just the right angle and force to change the axis of the planet thus creating havoc and permanently altering the weather conditions?

Not only that but I have read about the earth's axis shifting because of Antarctica's polar ice melting. According to the following article: Read This to learn more.

It says that Tsunamis are caused by axis shifting of the planet, not volcanoes, but I am not a scientist. The article does sound interesting to me though. You might want to give it a read.

The current tilt of Earth on it's axis is provided here - "During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees." -source: earthobservatory.nasa.gov and the full article is available here to look at.

Tsunamis aren't caused by 'volcanic activity' per se . It is the result of seismic activity; i.e., it is the energy wave caused by earth displacement and that energy wave is traveling through or 'displacing' water. This causes the water to react in a number of ways. Thus, volcanic activity is simply one, potential cause.

Did Antarctica create the shift or was Antarctica created because of the shift? Remember, Antarctica is actually a land mass. Did the tectonic movement of Antarctica cause the planet to tilt, placing Antarctica farther from the sun, allowing the build up of snow and ice, which then increased the tilt? What caused the tectonic movement? Was it a natural process or was it precipitated/accelerated by something? These are all questions still being studied.

Yes. A tilt in the Earth's access can, will, and has created climate change.

I don't see why not, it appears to be a perfectly possible occurrence.

The way the weather is changing - something that has never happened before - it is possible this phenomena may have already happened without anyone knowing about it - just an assumption.
