Effects will be world-wide but quite mild in many places. The effects of the planetary alignment will likely effect gravitational pulls of the planets...each having some and thus our magnetic field. The overall effects of which though, being attenuated by the great distances between the planets.
That may change the forces and structure of our very important and protective magnetic field. That may mean that we may lose some of it protection from the sun's influence on weather and because the suns energy has electronic potential, could effect communications, satellites etc....so they are at risk. That may be about all there is.
Here's a serious answer.
(This is usually where I rant about the poor science education in the US).
The force Venus would exert on us is about 1.13x10^18 N. The sun exerts a force of about 3.3x10^22 N. That's a difference of 4 magnitudes (a factor of 10,000). Venus is gonna have a wee tiny bit of effect on earth compared to the sun.
Venus does not effect our space weather. Sunspots, solar flares, and coronal hole hi-speed streams do, however. There's a lot of info about that at www.sec.noaa.gov.
I swear, there are a lot of people in America (less so in Europe) that have to have some apocalyptic scheme hanging around. This particular myth also occurred around 2000.
...fixed typos...
Engineer ? I am curious in what field. It is not important either that it offers what should be a healthy and real curiosity. Apparently it has not. But all seriousness aside...here are the competing positions kinkroids. The only mythology here is the ability to grasp concepts from the written word and numbers. This has been predicted by the Romans, the Chinese and the Mayan's.
What happens ? It has been said a complete alingment of the planets...some say no there will not be such an alignment and most of that alignment occurs regularly and the rest is bunk.
First, Venus is a side note...and the view we should get is only a bonus.
However, the gravity you describe is as measured under non-aligned conditions. We'll get a much more powerful chance on 12/21/12...so we are told.
So at least according to many astronomers and mathematicians...this is the case.
Some are saying there will be no changes at all...I hope they are right.
We are told...that's all, that the planets in our solar system will be at some point on 12/21/12, vertically, horizontally, geometrically aligned on the same plane and axis.
This we know from using that rudimentary methodology otherwise known as mathematics. The same methodology we use for all of those other astronomical 'mythology' like years and orbits and eclipses...ya know, mythology like that. So who do you believe ? To what end does any interested observer want to suggest such a celestial phenomenon is not going to occur and if so...what does the math really show for 12/21/12 ?
What will happen ? Science tells us...we don't know. Hence these two previous sentences:
Ok, nothing about how the world is going to end. Not only is the world not going to 'end' but it won't matter that you were right.
Otherwise, let's get a few important things in first. According to the science, it is not very likely at all that there will be anything like a world-wide, natural apocalypse.
We ok now ? Good.
What science that we do know presents a number of possibilities about which we can only truly speculate. From what we do know that is present in all of our solar buddies is a set of universal forces otherwise known as gravity and magnetism.
The resulting interaction of these forces subject to the aforementioned attenuation offered by the distances involved yields a limitation on our speculation. That limitation is as yet not entirely known because science...doesn't know.
For example, when the planets are aligned there may be effects on the gravity and the magnetic fields of both immediate bodies meaning for us Mars, earth and Venus all aligned may cause changes to all 3. Then just for fun, let's add a 4th & 5th...Mercury and Jupiter. Now our current measurements become potentially much less conclusive.
More science tells us that any distortion might result in the effects I described. The scientists believe that the threat is plausible enough to suggest communications and satellites should be taken offline for a day.
That's it.
World-wide weather problems ? Maybe ? Shift of our axis ? Most doubt it. Changes in subduction ? Maybe. If all true ? Lottsa problems...if, IF there is going to be that complete system alignment.
That's why the title Doomsday coming (?)
