Yeah I know its been happenin for a long ass time but I think it has to do with the way we live...
emissions from automobiles and other such sources release chlorofluorocarbons into the air, which are generally stable, which is why we thought that they wouldn't do any harm. but when they get higher in the atmosphere, the uv rays break them up, and the chlorine from the CFCs react with the ozone in the stratosphere, breaking it down into regular oxygen. this has created the hole (which is more of just a thinning) in the atmosphere, which lets more UV rays and has caused the skin cancer scares and stuff. the biggest problem, however, is the carbon dioxide thta is released, which traps heat from the sun. this warms the planet (one degree fahrenheit average over the past 100 years). that can cause shifts in the climate, whether it be big (such as the movie The Day After Tomorrow, which is surprisingly accurate in terms of the possibility of the current shifting) or small (such as a few more hurricanes or tornadoes). either way, a change in the temperature, however minute, can drastically affect the global sttability of the climate.
