I only just saw your January 9 mention of me in my DA notifications, apparently so I would read your chart about Australia's 1974 fires. Research however *immediately* shows that it was only a difference in total acreage. The "total land size" of fire was greater, but concentrated mostly in hot, dry land where it was not exactly shocking. The more recent fires affected a wide, wide range of environments including several that are normally too wet for fire year-round. Almost the whole of Australia experienced hotter, drier conditions than are on record, and some of what burned had never been on fire in decades or centuries. That several such sites burned at the same time should be evidence enough that the climate is shifting on a broad scale, rather than localized incidents or typical, random fluctuation. Living species have extreme power over the climate, and in turn trends of weather. Even the feeding and migratory activity of a single animal species can affect long term climate
