Where I live, each years weather wind patterns seems to change. Several years ago easterly winds blow onto the east coast of NSW from June to December. The next year mostly southerly winds during winter were experienced. Westerly winds 10 years ago during winter were often experienced.

Carbon dioxide is a gas that is heavier than air. Carbon dioxide causing the 1990s claims of the hot house effect, seems to have been forgotten.

Ocean waters consumes carbon dioxide gas. The huge 65% of earth's oceans, oceans 2 mile deep?

Global warming; climate change, is one more irrelevant media irritation to many people listening to media because they have nothing better to do.

Climate change is one more reason for politicians to get in front of populations' faces. like priests going on about god, climate change is an opportunity to misdirect peoples real life concerns.

What may be happening is politicians don't have to do anything for citizens, while being seen to be somewhat doing something for the future.

Perhaps this will give you clearer picture of the situation in Australia.

The northwest has got noticeable wetter, but the main areas where people live has got a lot drier, and this is just the point about climate change, the rain fall patterns are becoming more extreme.

Similar patterns are expected world wide, that is the wet tropics will become wetter, and the mid latitudes will become drier. Regardless of changes in rainfall pasterns, higher temperatures lead to higher rates of evaporation, which in turn means more rain is needed to avoid drought and bush fires.

It is also fairly certain that increasing population is only going to exacerbate global water problems.

The current situation in Australia is we are in an El Nino weather pattern, plus the Indian ocean is some 3 Deg C warmer than average. The El Nino leads to cooler winters, and hot summers in Australia.

The warmer Indian ocean generally leads to more cloud cover over Australia. So far this year the local climate is behaving as expected but watch out for this summer.

Many have seemed to be misunderstanding what I am trying to be saying, it is not just about a so called now traditional "drying climate" as per the environment, but many other factors that a taking out a huge chunk out of the lives of humans.

Many people are now so 'dry' in the context of less thought, a lack of ideas, no solutions, no real personal directions for the future, a lifeless life, opinions of the past 'drying out' due to different beliefs and money always seen now by some as being the answer for everything.

This is where the drying environment is a huge issue to address, let alone anything people may see as natural or not, also important. Environment and humans need to co-exist.

Warmair, you are confusing weather with climate. The map from the 70s proves little, as can be seen by looking at the map from the 60s. Cherry pick your starting point and almost anything is possible.

I'm also interested to know how they come up with those little puddles of drying. Why are they circular, and how is it that all around them rainfall can go up, but they go down? I suspect it is an artefact of the measurements.

There is no doubt that south west Australia has been drying out, and that there is more rain in the north in the last hundred years, but there is also more rain most everywhere else.

And the issue isn't where people live, so much as where they grow their crops.

Of course there is nothing in these maps to support the idea that weather is becoming more extreme. It's all pretty steady steady.

Actually no I am not confusing weather with climate.
Climate is usually defined as the average conditions over a period of 30 years whereas weather is strictly short term as in hours, days, or months.

The second link I gave started at 1970 which is actually the start of the period, when anthropomorphic climate change starts to become apparent, and is well within the definition of climate.

I specifically gave two links one starting one starting in 1910 and the other in 1970 to demonstrate that the climate was becoming more extreme. The longer the period you choose the less extreme the trend becomes, because it includes a longer period when conditions where stable. In fact if you step back through years starting in 1970 this becomes obvious.
