No. I have data and evidence that backs my views. I don't expect others to agree with me because I've said something. You, on the other hand, expect us to believe something just because you state it as fact.

You're projecting your bull****.

I've already detailed, a few times, the fatal flaws in McCanney's comet model. His model is wrong not because I say so, but because the data and evidence don't support his claims.

The earth is more-or-less a sphere - not because I claim it is, but because all the observations we have leave us with no other choice. You see, gaffe, scientists go where the observations and reality tell them to go. You go where your dogma and fantasies demand that you go, reality be damned.

What climate change is happening to other planets in the solar system

There are three fundamental flaws in the 'other planets are warming' argument. Not all planets in the solar system are warming. The sun has shown no long term trend since 1950 and in fact has shown a slight cooling trend in recent decades. There are explanations for why other planets are warming.

Martian climate is primarily driven by dust and albedo. Global dust storms increase the surface albedo by settling brighter dust on dark surfaces. Higher albedo leads to more sunlight being reflected which has a cooling effect. Snapshots of Mars' surface in 1977 and 1999 find that the surface was brighter in 1977 and darker in 1999. However, this doesn't necessarily point to a long term warming trend - the 1977 snapshot was made shortly after a global dust storm while the 1999 snapshot occured before a dust storm. Consequently, there is little empirical evidence that long term global warming on Mars is occuring (Richardson 2007). More on Mars...
Neptune's orbit is 164 years so observations (1950 to present day) span less than a third of a Neptunian year. Climate modelling of Neptune suggests its brightening is a seasonal response (Sromovsky 2003). Eg - Neptune's southern hemisphere is heading into summer. More on Neptune...
Neptune's largest moon, Triton, has warmed since the Voyager space probe visited it in 1989. The moon is approaching an extreme southern summer, a season that occurs every few hundred years. During this special time, the moon's southern hemisphere receives more direct sunlight (Elliot 1998).
Jupiter's storms are fueled by the planet's own internal heat (sunlight is 4% the level of solar energy at Earth). When several storms merge into one large storm (eg - Red Spot Jr), the planet loses its ability to mix heat, causing warming at the equator and cooling at the poles (Marcus 2006). More on Jupiter...
Pluto's warming is not clearly understood. Pluto's orbit is much more elliptical than that of the other planets, and its rotational axis is tipped by a large angle relative to its orbit. Both factors could contribute to drastic seasonal changes. As Pluto's orbit is equivalent to 248 Earth years and observed warming spans only 14 years, it is likely this is a seasonal response (Sromovsky 2003).

No-one says that we are the "only" causative factor in climate change. That's a strawman.

However, since it's clear you've done precious little research, if any, on the subject, I recommend you check the links I provided baja to give you a start.
