World Jump day

Thats madness!!!!! Lol, ooh dya reckon it might make the world a tad warmer>!!! that'd be nice!!!! Wouldnt mind hearing a scientific explanation of how that works though, coz if people all over the world are jumping, surely its just gonna counteract each other and not do anything!!! It'd make sense if it was all on one side lol
or am i just being thick?!!!!
