It depends how much energy and electricity you use in your life time. It measures your carbon emissions.
From 1934 until 2010, the last year we have complete data on, the planet has seen less than 0.2 degrees (C) of actual warming despite man's 80 times increase in carbon dioxide emissions. This is partially due to the small amount of overall emissions that man is compared to the rest of the planets natural emissions.
No. it is not normal because then youd have to be an alien.
Make yourself a billionaire, then go and buy a aeroplane company then u can have as much aeroplane as u can!
Hybrid cars have substantially lower exhaust emissions than normal cars and are better for the environment. Hybrid cars of all types get much better mileage per gallon of gas than normal cars.
No, men travelling to the moon would have very little effect on global warming. Emissions from spacecraft do add carbon dioxide (CO2) to the atmosphere, but not much more than an aeroplane. Emissions from burning fossil fuels (coal, oil and natural gas) is the main cause of global warming.
That depends on how much it consumes, and how far it is going.
Get on an aeroplane and find out.
