Global Cooling 2010

Jump to new
On the other hand a hot day in Adelaide is enough to awaken the alarmists and assorted political opportunists, all beating their breasts in assumed piety, yea verily, it's 40 deg in Adelaide, here is the proof of all we have said. The attempted brainwashing is relentless.
Which Carpals's post, and this thread is about.
 
It is a beautiful morning in Townsville. Good rain over the last 10 days or so, and a bit overcast.

Its still very very cold in Scotland I am told.

Weather is ever changing.

Years before people started to talk in headlines about the climate our ABC had a few stories on climate change. ABC normally does a reasonable job of science reporting on dedicated science shows like Quantum and Catalyst.

People appear to be happy to take areas of the world and claim things are happening to the contrary. It's about the overall state of things.

Gore being from USA focused on the parts to get headlines to get people to notice.

Way back when the reports on the above mentioned science shows on ABC often used the expression climate change mentioning an overall warming. They also pointed out the weather would become more extreme. Some areas will get more rainfall, some areas would get less rainfall. Some areas will get get hotter summers while some areas will experience more bitter winters. Even storms will be more energetic. That information reported back in the 1980s and 1990s appears to still hold up. I don't think that will matter because people will mostly stick to their own opinions.

Climate is a complex system and scientists are still discovering various interactions. For example the Indian Ocean has some influence over the overall rainfall of Australia yet only the Pacific Ocean was used predict rainfall.

Methods and data used now were not used in the past so for some parts of modelling the historical data is too short. Also we know the sun is a major influence. Another 20 years I'm sure people will be taking more notice.

There can be periods where abnormalities can occur. Hopefully the last few years fall in to that else things don't look so rosy. Like how the 1950s and thereabouts things were wetter than now (and the past) which is when a lot of farm expansions took place.

Like the Antartica reports. Some of them have had follow up reports including the idea East Antartica is gaining ice. Follow up reports have shown it isn't gaining ice overall. It was closer to in balance between gaining and losing ice. Gaining ice at the interior but losing ice at the edge.

Can humans influence the weather systems and climate? That is the question that is at the crux of the problem. Hopefully it is a yes. I don't know about you but I would be happy to get to a time when southern Australian summers had less extreme temperatures.
 
No it's not a good analogy. Warmists try use use such simple analogies all the the time, but the truth is that climate is so complex that there are no simple analogies.

Another favourite. It's one I have little sympathy for while everybody expects everybody else to do the risk mitigating.

Al Bore being the numero uno example.
 
communique,

From that article you highlighted....

Antarctica is warming, but not melting anything like as much as expected.

NO, it's not melting. The IPCC reports themselves acknowledge that Antarctic sea ice is GROWING. So which is it, the article is plain wrong or the IPCC report (2007) is wrong or both are???

A classic example of media bias. It's 41.3 degrees, in Adelaide, in the middle of Summer!

What next? Snow in the mountains during Winter? Rain on the west coast of Tasmania? Fog in Melbourne in July? Maybe it could even get a bit humid in northern Queensland!

41.3 in Adelaide isn't an unusual event and it's common knowledge that Summer in Adelaide tends to involve a number of very hot days each year. It's always been that way and probably always will be.

If it snows in Darwin then that would most certainly be an unusual event as would ice in Sydney Harbour or temperatures over 40 in Tasmania. But to be reporting normal, expected weather conditions as though they were some kind of freak event is sensationalism at its worst and clearly intended to influence opinion over climate change.
 
Waynel, did you like the bit on the above ABC article referring to the ignorant short sighted chatter on the blogs.

Anyway, on topic, I do not really know either way except to say that the possibility of doom for the future of the planet for our coming generations makes me want to be active to help sway opinion towards cleaner energy and the etceteras for conservation and population control.

Seven year old a month or so back, "don't worry Pop, we are going to have big space ships to take us to new planets". Loved the sincere certainty in his eye. Not so sure myself.
 
Smurf1976: Approximately 11-12 months ago Tasmania did experience temperatures above 40 C. Not many locals adapt to such temperatures too well. Many in Tasmania don't have air conditioning.

Temperatures above 40 C in Adelaide are still not something that happens daily in summer. It would be interesting to count how many days above 30 C and above 40 C for the last century for each summer season.
 
I'm well aware of what happens when it gets hot in Tasmania - I'm sitting at home in Hobart right now. Basically, there's just about nothing that was built with those temperatures in mind and the end result is it turns into an oven if it's a house / commercial building or breaks down if it's a factory etc.

But ever since I was a child, I've known that most summers there will be a day or two in the high 30's in Hobart and that comparable hot days in Adelaide involve temperatures well into the 40's. It's nothing new even though it's not that common. Some years it doesn't happen, but often it does.

My point though is this. If it's 40 degrees in Adelaide then the media gets excited. But you don't get the same response if it's 20 degrees despite that being equally far from the 30 degree summer average maximum for Adelaide. The media just loves to report hot weather. It's not just the media though - people generally seem to get excited by the heat. I can understand that in a cool climate, but not in Adelaide where heatwaves are to be expected...
 

I lived in SA for 22 years and every summer you could expect at least 2 or 3 'heatwaves' where you get a few days (or more) in a row above 40. Its just normal as far as im concerned

I don't think anything has changed. I remember visiting relatives in Adelaide as a kid and sleeping outside on the verandah due to 40+ deg heat.

Now that was a few decades ago -

We visited there again about three years ago for Christmas and stepped out of the aeroplane into freezing conditions (freezing for us Queenslanders!). Shivered our way through Christmas with borrowed jackets but by the time we left a week later it was 40+ heat.

It would seem that climate the world over is fluctuating like it's always done...

Precisely! If there is one thing that characterizes Adelaide weather in summer, its the customary 'heat wave'. I've lived here long enough to know that.

Nothing to get excited about! Back in the day you'd think nothing about it.

Now the media takes it upon itself to make a big deal about it all. I guess it sells papers in this era of climate hysteria.

All this global warming crap is getting very old, move on folks!

A few points need to be made here from an unbiased perspective:

1. Undoubtedly SE Australia is one of the hottest places on the planet in certain circumstances. Just have to look at the article that came out after the Feb 7 fires last year that discussed the intense nature of fires in the region and how it is simply a matter of location and prevailing weather patterns that make Vic in particular the bottom of a huge funnel that channels the heat energy from 2000-odd km of very hot interior! No question that Vic has always and will always have the potential to reach high 40s, just a matter of physics.

2. The Gulf stream problem is a definite possibility in providing an answer to the very cold conditions in Britain and the east of Nth America. However this would not necessarily extend to continental Europe or China where they are also having majorly cold conditions. But IF climate change is occurring then it is certainly possible that more extreme conditions will result in both directions, eg colder and hotter.

3. REGARDLESS of whether increased greenhouse gas levels in the atmosphere CAUSE an increase in average temperatures, there is no question that increased CO2 levels will cause ocean acidification, which is a serious issue that COULD have a major impact on ocean ecosystems.

Just my
 
1. Agreed there. Just about anywhere in SE Australia can certainly reach extreme temperatures and it's not that uncommon. Worth noting that in terms of extremes, the coldest capital city in Australia is in fact Darwin - they just don't get the extreme heatwaves up there.

2. Gulf stream I'd assume could be measured in some way to verify if this indeed the cause of the cold weather?

3. Ocean acidification and the plight of the oceans generally is potentially a huge problem that seems to be almost universally ignored. It's time to stop dumping rubbish in all its forms into the oceans whilst ripping everything (fish etc) out that we can get our hands on. That just can't end well and the warning signs are there for anyone who cares to look.
 
I couldn't resist posting this common occurence in the UK and US, but not I'd say in China.

The theories about ocean acidification due to CO2 levels rising, and being bad for everything are probably off the mark.

Looking at long term history, like 600 million years, we are currently at very low CO2 levels.

This site gives a very quick geologic history, and a few things to think about....

http://www.geocraft.com/WVFossils/Carboniferous_climate.html

In the last 600 million years of Earth's history only the Carboniferous Period and our present age, the Quaternary Period, have witnessed CO2 levels less than 400 ppm.

Have many people here thought outside the square, in that perhaps we SHOULD be creating higher CO2 levels in the hope of warming the planet up a bit, so that the temperature returns to a more normal historic level???

Sewage should not be pumped not into ocean, but utilised or at least pumped to arid or desert areas, so vegetation can dispose of the nutrient and neutralise acidifying effect.

Fertilisers when applied should have better protection from being washed away to river system and to oceans.

Fish breeding programs could help to replenish fished out stock, like with farmed forests; we can help fish to breed.

Not to mention 1 CHILD POLICY for the whole planet for a generation or two !!
 
In simple terms (and I'm paraphrasing someone far more knowledgeable than me), most of Britain's weather is determined by the temperature of the North Sea. The Artic ice sheet is thinning so more cold water moves into the North Sea (and further south before it is warmed, too) as well as more iceburgs moving south as the ice sheet becomes more "fractuous".

This in turn effects the weather patterns in Britain, especially the Northern areas which are very suceptable to changes in Sea conditions.

Anything more scientific than that and my first-year oceanography knowledge from many moons ago tends to wear a little thin.
