Alien Apocalypse. Global Warming is coming and I'm sure by now you have all heard the inconvenient truth. What I wish to do within this article is ignore the smaller things that individuals can do and to take a look at achievable options on the macro level.
It's all really properly to obtain a hundred folks to alter their metaphorical footwear to these with smaller carbon footprints, but what we seriously want is something Large...
#1. Photo voltaic Umbrella
Roger Angel's "sun shade" concept does precisely what it says around the tin. He proposes a large, photo voltaic parasol be erected among the Earth along with the Sun to shield our planet from your intensive heat. His umbrella comprises 16 trillion flat discs, every about one yard broad and weighing much less than 1 oz, that attach with each other to develop a large surface region shield in a position to take in about 2% in the incoming heat.
The discs could be launched in around 20 million rockets along with the project would price around $4 trillion over 30 years. Needless to say this factor would be fantastic - a massive monolithic construction that parasols the whole earth, and at a somewhat tiny price contemplating it'll make sure the survival of your entire human race!

I'd actually like some feedback right here on regardless of whether or not this could be completed with ordinary parasols rather than high-tech discs - my own research is, at current, inconclusive. I'm functioning on the premise that each individual in ownership of an umbrella or parasol contributes theirs towards the scheme but I've hit a wall in some of my thermodynamic calculations.
#2. Earth Command Method
Think about a situation exactly where we are in a position to bodily "drive" the Earth away through the Sun as its intensity raises or as our planet gets hotter. We could make certain that the Earth is constantly at an optimum distance through the Sun - making certain crop development along with a secure temperature for the polar ice caps! World-wide warming elevated radically this 12 months? No problem, let's just move the Earth 100,000 light years away from your Sun!

A super yacht-style rudder will not suffice to harness the photo voltaic winds seeing as even a "giga-yacht" is only 100+ metres whereas the Earth measures approximately 12,800km in diameter. This rudder would need to be so large as to be impractical - we might too put Archimedes on the Moon and give him a huge pole with which to lever the Earth.
Now, taking the film Armageddon (1998) as my scientific study, I am aware that we can harness the gravitational pull of other celestial bodies to "slingshot" our planet by way of Space. So, by attaching some first jet-engines to one side from the Earth's surface we could start to propel our planet into nearby celestial bodies. The obvious target is Mars.
I realize what you are going to ask. "Come on, Is Mars seriously large enough to have a gravitational pull strong sufficient for us to slingshot ourselves?" The answer is: indeed and no. Mainly no. Mars features a gravitational pull of three.7m/s squared - whilst that of the Earth is 9.81 m/s squared. So we can't slingshot ourselves from Mars. What we are able to do, nonetheless, is propel ourselves in direction of Mars with our thrusters and use Mars' weak gravitational pull to gradually "float" past it and into a target secure haven - on this situation the chaotic asteroid belt just before Jupiter.
