Antarctica Has Coldest Winter On Record

Australia has been in "climate flux" since the invaders, err, invaded.
How dare we "Flux" Australia!
Australia wasn't "fluxed"before the whites came, and now it is totally fluxed.
Oh, the humanity. <facetiousness>

BTW, This is the land of "droughts and flooding rain", after all.

Global warming causes extremes of both cold and hot weather in regional areas of the globe. Evaporation in some parts results in increased precipitation in other areas or even a drop in temperature in others. This is not cyberdad's opinion it's scientific fact.

I believe "climate change" is a natural phenomenon whose mechanisms have been accelerated by man-made agents.

Yes, climate change is always happening.
Q: Has the earths total temperature, before industrialization, ever been this hot or hotter?

Look at the trends. NASA have been collecting this temporal data for quite a while now using ice cores.



Going back to the graph, 1950 was an important milestone as it had been 10 years since the heavy global industrialisation for arms/shipping following the outbreak of WWII. After 1950 India, China and Russia became fully industrialised so the point where the CO2 line was crossed is no accident.

Long-term temperature reconstructions often rely on the width of tree rings: they assume that warmer summers make for wider rings. Using this measure, it seems that global temperatures changed very little over the past two millennia. Such studies are behind the famous “hockey stick” graph, created by Michael Mann of Pennsylvania State University in University Park, which shows stable temperatures for a millennium before the 20th century.

Jan Esper of Johannes Gutenberg University in Mainz, Germany, thinks that at least some of those tree rings actually show something else: a long-term cooling trend that lasted right up until the Industrial Revolution. The trend came about because of reduced solar heating caused by changes to the Earth’s orbit known as Milankovitch wobbles, says Esper. His results suggest the Roman world was 0.6 °C warmer than previously thought – enough to make grape vines in northern England a possibility.

This is a chart of CO2.
Did you know that?

The IPCC buries two millennia of fluctuating temperatures
Alan Moran.

The controversial part is the removal of temperature oscillations commonly thought to have occurred over the course of the past 2,000 years. These include warming that was known to have occurred in Roman times and again in the tenth century when the Vikings colonised Greenland until 1250, and the cold period 1400-1700. Such events are downgraded as being either exaggerated or localised.
