It seems that climate change is really picking on Australia in a big way. Scientists at the National Oceanic and Atmospheric Administration (NOAA) have created a climate model that indicates a trend to declining fall and winter rainfall over the southwestern, southern and eastern parts of the Australian continent. The cause - greenhouse gas (GHG) emissions and ozone depletion.

Only the Nagasaki bomb dropped three days later offers a comparison with more than 80,000 lives snuffed out.

Two stories this week on climate change caught my eye. The first was a report on ocean waves in the Arctic. When you think of the Arctic Ocean you think of an endless stretch of sea ice with an occasional break. You envision polar bears roaming the ice surface. You don't think of big rolling breakers crashing into shorelines.
