We humans are on track to increase the amount of co2 in the atmosphere so that the concentration in the future more than double the atmospheric co2 concentration that existed for the few millennia before the industrial revolution. if we could cause just a doubling and then hold the co2 level constant at that doubled level for the next thousand years, we very likely would see:

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
