As things are right now there is the unfortunate problem that powerful people can talk or bully state attorneys into dropping cases (i.e. Hillary Clinton's missing emails or the periodic "Mayor's son raped a woman" cases) but at least you can follow those up by hiring a lawyer on your own dime.
Hitler could only start WW2 in the 1930s because he had a willing base of angry Germans with a mix of justified and unjustified grievances. He was the "first past the post" politician to harness those frustrations but if he hadn't existed some other populist would have, if not a Nazi then a Communist. 50 years later the situation was entirely different, the people content, and nobody could've gotten a majority support for political upheaval. We know this because the RAF certainly tried to.
As far as chemical means go, CO2 is incredibly stable. Even if you do find a way to convert it down to carbon and oxygen by spending inordinate amounts of energy on chemical processes you still end up lowering the pressure by only one third (since the other two thirds are oxygen) and you now have a planet where everything you bring down to the surface will go up in a fire immediately.
You could instead combine it into carbonates but you'd need huge amounts of cations for that and I'm not aware of any significant source of such ionized materials that aren't already combined into salts.
Physically removing it is out of the question because you'd need to find a way to accelerate the entire atmosphere to escape velocity. Just knocking a few asteroids into it won't help much because the gases will never leave Venus's sphere of influence and should return over the next years.
Gerrymanderization of districts: http://www.geoideas.net/wp-con...
WV, IL and MD are truly gerrymandered democratic controlled states. As opposed to the entirety of the southeastern US from Texas to Pennsylvania that are republican controlled and gerrymandered.
Hokkaido is a bit of a bad example though since there's no Shinkansen service through the tunnel.
Going 1500km the other way to Kagoshima the train takes about 7 hours, and the airplane 5-6 (from city center to city center). That's with the 270km/h regular Shinkansen. If you increased the speed to maglev levels the train would outperform an airplane.
One hour? If "ease of use" means to have to wait a full hour for confirmation whether the purchase of your coffee went through or not I think I'd rather use cash...
How does this seem appropriate? Chinese oppression is pretty clearly aimed at perpetuating the party rule and guaranteeing their members cushy jobs and a steady income.
There is literally nothing we could do about a Kansas-size (500km) asteroid but that scenario is highly unlikely, there isn't any evidence that such an impact happened anywhere in the solar system in the last 3.5b years.
A realistic scenario is an asteroid between 100m and 1km, and ion thrusters and nuclear propulsion have a high enough efficiency that they can influence that category.
Not sure about Hitler or Mussolini - they mixed up ideologies of left and right.
Richard the lionheart was driven by religion
Hitler himself was solidly right. The NSDAP had a leftist wing led by Gregor Strasser (the Strasserists) but Hitler showed him what he thought of that in 1934.
With how smart these choppers are getting this shouldn't even be a problem. Just buy three of them for any two jobs and have them find their own schedule to "sleep" when they need to so that there's always at least the required number up in the air.
They originally planned to use 60 miles of wiring but then they only ordered 60 kilometers of wires so two thirds of the devices are not connected. It's not that big of a problem though since most things are covered by redundancy.
