Robert Zwilling | 2034 comments People talk about the ocean currents changing but what kind of changes could be in store for Earth if the parameters of the jets streams change.

The jet stream is driven by the temperature difference between polar regions and the mid latitudes.

The changing Arctic temperatures are causing the jet stream to be found in different places than normal positions of the past and to have splits in the stream making forks which change the weather inside those forks from what is normally seen. The weather patterns above and below the jet streams are also changing.

Ken Kroes (ken_kroes) | 69 comments Thanks for the great info and links Robert.

I did some, back of the napkin caluculations and our CO2 emmisions have effectively increased our Sun's energy output by over 1/2 percent. (naturally, our Sun is expanding and getting warmer, but takes about 50 million years to increase in energy output by the same amount).

The planet WILL react. Not quickly or in a straightline, but things will change (like the jetstream, ocean level, ocean currents etc).

Robert Zwilling | 2034 comments It shows up everywhere as background energy. Everything gets a "free" boost that uses energy. You would think everything remains the same but it won't. From bacteria to fires, anything using energy will be more powerful or plentiful or noticeable by just doing what it always did. The air will require less push to get it moving relative to how it used to move. It will still move the same way, just with an extra push that will continue to increase for awhile. Any ideas on how much greenage we would have to plant to offset the loss of free oxygen our lifestyles have been using up and not replacing?
