Weather or not

We planted this hakea four weeks ago; you can see the new growth, about 15 cm!

The concept of global warming has led to a massive increase in resources devoted to the study of climate … but I wonder how much closer we are to actually understanding it.

Just as the study of the human body leads to an ever-growing awareness of its amazing complexity, could it be that the more we learn about the weather and the climate the less we know for sure?

The esteemed British science journal Nature has just published an article on new research about why seawater in the Antarctic has stayed the same temperature while other parts of the world have warmed up.

In a nutshell: “Observations and climate models show that the unique currents around Antarctica continually pull deep, centuries-old water up to the surface — seawater that last touched Earth’s atmosphere before the machine age, and has never experienced fossil fuel-related climate change.”

You can read the Nature article here.

It quotes the lead author Kyle Armour, a University of Washington assistant professor of oceanography and atmospheric sciences, making the observation: “When we hear the term ‘global warming,’ we think of warming everywhere at the same rate,” Armour said. “We are moving away from this idea of global warming and more toward the idea of regional patterns of warming, which are strongly shaped by ocean currents.”

And they told me the science was settled!

Back in downtown Alice Springs, I checked out the long-range forecast from the Bureau of Meteorology for Northern Australia last week, to be warned that the outlook for winter in Central Australia was for colder days and nights than average.

In anticipation of some early frosts I flicked to the seven day forecast for Alice Springs to find that that, after an unusually mild Autumn, we could expect two days with maximums over 30 degrees this week!

I can’t recall June days over 30 since the early 90s, when I was convinced we were all going to fry. Perhaps we still will,  but the real cause, it seems, was less anthropogenic global warming than El Nino (“the boy”), the weather pattern that causes heat and drought – at least in some places.
