Very cute, and not unexpected from someone of your ilk.

Hate wasting my time with such nonsense.

Aggravating and meaningless.

I've long advocated more intelligent use of our waste stream, as El Dotarto will affirm if you ask him.

I've also long advocated for far more energy-efficient buildings, lighting, vehicles, and other things to which we become accustomed.  And I've incorporated many of those things I've said into my little house in the Mojave Desert.

My house looks just like many others out here, but consumes less than half the energy.  Mostly that's accomplished through the use of triple-paned windows, good insulation in walls and ceiling, a solar farm to drive my evaporative air cooler during daylight hours, and the use of LED lamps throughout the house, placed for maximum use.  That all works quite well.

Oomp!  Great post!!

This is a very interesting set of scientific facts.

I fear they may be lost on those on the opposite side of the debate.

I imagine some pointless memes are coming your way.

Are gliders used in Climate science research?

Which part of it was nonsense?

Where is your evidence to back up that claim?

Aggravating and meaningless?

You're describing yourself, John.

Are you so incapable of seeing another person's point of view that you would rather look like an ass before exhibiting any sign of cognitive ability - or "weakness"?

I find it so frustrating that the answer to two problems is RIGHT THERE, but for some reason it's in the too hard basket?!

Some years ago there was an interest in converting waste to fuel.  It was called, "Anything into Oil," and if memory serves, it seemed limited to the use of animal byproducts, but I think that with suitable modifications it could possibly take our whole organic waste stream and process that into useful materials.  One advantage I think it might present, would be a reduction in the use of fossil fuels, substituting some of that with the use of what I call short-term carbon cycling - - as foodstuffs are usually grown within a year of when they are consumed and human waste produced.  Same thing with most yard clippings.  Just how much of that waste stream could or would be turned back into fuels I have no idea, but our local landfill produces enough methane to fuel a local powerplant, and most of the organic waste is still in that landfill.

>>Are gliders used in Climate science research?<<

I really don't know- it was just an observation in that particular flying club 40-odd years ago.  I doubt that there was much  concern about ecology, more about the effects on glider performance. These guys were pretty technology oriented -a few  were aeronautical engineers- and were serious about their experiments, but their #1 concern was always "What will make this thing go farther?" and, for that matter,  at the time nobody much talked about climate change / global warming.  They were just into lighter/heavier air and such. 

As I  alluded,  I wasn't  into it enough to really understand what the deal was, just found it a memorable observation.

How does climate change attribution work?

The basic principle behind climate change attribution is comparing the world as it is, with how it would have been without human-induced greenhouse gases.

To do this researchers use climate models which work like computer-based virtual worlds, to recreate the real world as closely as possible.

They then look at two sets of model experiments, one which is as close as possible to the current world, and one where the human introduced greenhouse gases have been removed.

"We look at the frequency of that specific event between those two simulations and then compare how often it occurs now, compared to the natural world — as we think it used to be," said Dr Perkins-Kirkpatrick.

"Essentially what we're doing is looking between those two groups of models and how the probability or intensity of extreme weather events [such as] heat waves, heavy rainfall events and droughts, are changing just between those two ensembles," said Dr King.

In the past, these attribution studies have found a link between the Canberra and Sydney Heatwaves of February 2017 and climate change.

For more complex weather events, for example Cyclone Debbie, or the 2011 floods of south east Queensland, Dr King says "it's harder to tell."

Part of the reason is that there is a lot of complexity in this analysis.

According to Dr Perkins-Kirkpatrick, "It's not that easy.

"A lot of time, a lot of blood, sweat and tears go into actually defining the event and making sure you've got it right.

"It's taken me weeks before to make sure I've captured the event as well as I can."

How the event is defined, the model used, which parameters are included and how the data is analysed statistically, can all change the outcome, so these simulations are often repeated many times to ensure a robust result.
