Canberra, Australia - August 24, 2014

Canberra will have just one day of wind and rain before a sunny long weekend is expected according to the Bureau of Meteorology.

Lunches across the capital were restricted to the tea room on Thursday when an early afternoon storm hit around midday.
Brisbane, Australia - September 25, 2014


Winds up to 100km/h (click here) and more than 30mm of rain lashed Brisbane on Thursday afternoon.

Localised flooding struck in Rocklea and Energex said more than 12,000 homes lost power in Brisbane's south.

"The main impact is Inala and the suburbs surrounding it," spokeswoman said.

Earth is counter intuitive when it comes to a warming climate. The Arctic Ocean in the northern hemisphere is an ocean and it's ice diminishes as do glaciers on land. But, Antarctica is ice on a continent. When the ice melts in Antarctica is runs off initially into the circumpolar circulation creating expensive sea ice.

The real concern is what happens to the extra water once it hits the ocean as water rather than ice. Increased sea level rise is apparent on every continent on Earth. But, as the water is exposed to not just a liquid state, but, a gaseous state due to increased warming there are huge storms with deluge of water over land. The land is warmer than the oceans.

One the once frozen water reaches the warmer land from storms it again evaporates and becomes water vapor. As time goes by the water vapor continues to move up in altitude until it reaches the upper atmosphere of the mesosphere. Once in the mesosphere the water molecules again condense to increasing layer of noctilucent clouds. 

Basically, as the poles of Earth lose their ice it eventually moves into an unusable layer of ice clouds in the mesosphere. It isn't must rising seas, it is far worse. Mesosphere clouds don't rain.

...The record was finally broken on 15 September and sea ice extent has increased since, according to data from the US National Snow and Ice Data Center analysed by Australia's Bureau of Meteorology in Hobart.

More sea ice may seem odd in a warmer world, but new records are expected every few years, says Jan Lieser of the Antarctic Climate and Ecosystems Cooperative Research Centre in Hobart. That's because the southern hemisphere warms more slowly than the north, as it has less landmass, boosting the winds that circle Antarctica and pulling cold air onto the sea ice.

The melting of ice on the Antarctic mainland may also be creating more sea ice, by dumping easily frozen fresh water into the ocean, says Nerilie Abram of the Australian National University in Canberra....
