ATLANTA -- Atmospheric circulation over the Pacific Ocean has weakened significantly during the past century, and scientists say the most likely explanation for the shift is human-induced climate change.
Although few people have heard of the vast loop of winds known as the Walker Circulation, its effects are felt worldwide -- as disruptive El Niņo episodes, seasonal Asian monsoons and the upwelling of cold water from the deep ocean that nourishes marine food chains.
"The Walker Circulation is fundamental to climate throughout the globe, and variations in its intensity and structure affect climate across the planet," Gabriel Vecchi of the University Corporation for Atmospheric Research said Wednesday. "The scale of this feature is enormous."
This one has a good diagram of the Walker Circulation Loop:

K - we have heard of the ocean currents that keep London warm are going to stop, and they will get Canadian winters like we used to get.
This Walker Circulation will have an effect - like what we are seeing now - in BC the weather just will not warm up, but China has 35oC a bit earlier than usual this season.
The kind of effects from Walker being weakened will be things we notice more easily, like cloudy rainy days instead of normal seasonal summer conditions. Maybe that will peeve people off enough to demand emissions reductions!!
Any government budget without emissions reductions is not worth anything.
