Strong belief in global warming is somewhat discouraged by the experience of this past winter and coldish spring. But regardless, (and not being an expert on Australia) it is my impression that Australian weather is very strongly related to the El Nino/La Nina oscillation cycle, and Australian farmers and ranchers pay a great deal of attention to it. Interestingly, the effect there is basically the opposite as the effect here. When the warm mass is in the western Pacific, Australian rain is generous and ours is not. When the warm mass is in the eastern Pacific, the exact opposite is true, though not in the whole U.S. The effect seems to be stronger there than here; something that conversation with Australian farmers and ranchers has confirmed for me, right or wrong. They study and base plans on that cycle more than any other single thing.Thanks, I liked the following paragraph from that article:
“A growing middle class in the developing world is demanding more protein, from pork and hamburgers to chicken and ice cream. And all this is happening even as global climate change may be starting to make it harder to grow food in some of the places best equipped to do so, like Australia. In the last few years, world demand for crops and meat has been rising sharply.”

Since the size and strength of the warm water mass bears a direct relationship to the amount of rainfall, one could argue that global warming, if real, may actually be helpful to agriculture, at least in some places. No one really knows, of course. But it does not seem unreasonable to believe that a warmup of equatorial waters in both the western and eastern pacifics could be beneficial to agriculture in the temperate zone land masses adjoining the Pacific.
