From Watts Up With That?<\/a><\/p>\n\n\n\n

Essay by Eric Worrall<\/strong><\/p>\n\n\n\n

\"\"
Some guy in a blue shirt, Dr. Will Happer, Dr Peter Ridd, and John Abbot, who is putting a huge effort into convincing Australia’s government meteorologists to surrender their state secret temperature records. And some random other people I don’t remember sorry.<\/figcaption><\/figure>\n\n\n\n

Following a rousing introduction by Dr. Peter Ridd, Dr Will (Don\u2019t call me a climate scientist) Happer presented a dazzling speech, in which he explained in simple terms why CO2 claims don\u2019t make sense.<\/p>\n\n\n\n

Will Happer spoke about his work creating reference stars \u2013 he pioneered the concept. Light from stars crosses the universe to finally land in our telescopes, only to be mangled by the last few miles of its journey through our atmosphere. Will\u2019s brilliant idea was to use lasers to create a reference light source at the top of our atmosphere, which can be used to untangle the damage the atmosphere does to the incoming light signal.<\/p>\n\n\n\n

Dr. Will Happer is a guy who understands atmospheric physics so well, he was able to confidently predict, just from theory, that it would be possible to artificially create an entirely new atmospheric state, which would help Astronomers use adaptive optics to correct defects in their photos.<\/p>\n\n\n\n

To appreciate Will Happer\u2019s genius, it is important to note that the reference star is not the laser beam itself, Happer is not just randomly shining a laser into the sky. The laser causes a small patch of a layer of the atmosphere to glow, just like a bright star. Will Happer figured out how to make that happen, by delivering the right laser frequency and intensity to trigger a predictable glow.<\/p>\n\n\n\n

I think from this you can reasonably conclude that Happer is someone who seriously understands the atmosphere and radiation physics at a level few others can approach \u2013 key concepts for analysing the Greenhouse Effect.<\/p>\n\n\n\n

One of Happer\u2019s most powerful slides was this one, which shows\u00a0the insignificant impact of doubling CO2 on the level of outgoing radiation.<\/mark><\/em><\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Take your time looking at the image above, because it took me a few seconds to get it the first time I saw this type of diagram. What the slide is showing is how atmospheric gasses affect thermal radiation escaping the Earth. The blue line is what radiation would be emitted by the Earth at its current temperature if Earth had no atmosphere. The Jagged line underneath the blue line shows the effect of atmospheric gasses partially blocking outgoing radiation at specific frequencies \u2013 the greenhouse effect.<\/strong> The reference to the area in the text, is because the area under the curves shows the total amount of energy escaping into space.<\/p>\n\n\n\n

If you look carefully, you\u2019ll see two lines sitting almost on top of each other, a dark brown line and a red line. You can\u2019t really see most of the red line, because the red and dark brown lines are intermingled, they almost sit on top of each other. The brown line is how much radiation is trapped by current CO2 levels (around 400ppm). The almost identical red line is how much radiation would be trapped if CO2 levels were raised to 800ppm<\/strong>.<\/p>\n\n\n\n

So what is the impact of raising CO2 to 800ppm, over today\u2019s value of approx. 400ppm?<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The impact of doubling CO2 from 400ppm to 800ppm, according to basic physics, is 0.71C of warming.<\/mark><\/em><\/strong><\/p>\n\n\n\n

How can anyone possibly still think the CO2 greenhouse effect is a problem, after seeing this diagram and calculation?<\/p>\n\n\n\n

The reality is almost all the radiation which CO2 can trap, is already being trapped. Adding more CO2 has almost no impact on outgoing atmospheric radiation.<\/p>\n\n\n\n

So how do alarmist climate scientists turn this trivial nothing into a global climate panic? How do they turn 0.7C of warming into 3C, 4C, 12C, whatever the latest panic figure is?<\/p>\n\n\n\n

According to Dr. Will Happer, they achieve this by adding unphysical, hypothetical positive feedbacks, which amplify the almost non-existent impact of adding additional CO2 to the atmosphere. But there is no proof significant positive feedbacks which amplify the minuscule CO2 effect actually exist.<\/strong><\/p>\n\n\n\n

The rest of Dr. Will Happer\u2019s presentation was just as powerful.<\/p>\n\n\n\n

If only we could photocopy this guy, and get him into all the classrooms of the world, the climate panic would disappear overnight. Which is probably why the left worked so hard to cancel him, when Dr. Happer was given a climate science oversight position under President Trump, and served a year on the America First team.<\/p>\n\n\n\n

We\u2019d all love to know what Dr. Happer could have achieved, had he received a little extra time. Let\u2019s hope Dr. Will Happer finds a letter from the White House in his mailbox in early 2024.<\/p>\n\n\n\n

A huge thankyou to the Institute of Public Affairs<\/a> for making the Will Happer speeches happen. And a big shoutout to Raj and Vijay<\/strong>, who over a few beers before the event entertained me with some interesting insights into the murky political games being played in the Aussie state of Victoria and elsewhere, details of which have somehow slipped beneath the radar of Australia\u2019s mainstream media.<\/p>\n\n\n\n

Correction (EW): h\/t MarkW<\/a> \u2013 400ppm to 800ppm, not 400C to 800C!<\/em><\/p>\n\n\n\n

Update (EW): h\/t\u00a0GC<\/a>\u00a0\u2013\u00a0There is no proof significant positive feedbacks which amplify the minuscule CO2 effect actually exist.<\/mark><\/em><\/strong>\u00a0But Will Happer went further than this, he spent a bit of time discussing why there is significant evidence such feedbacks don\u2019t exist \u2013 namely the observed stability of the global climate over geological timescales. Large feedbacks are not compatible with stability.<\/p>\n\n\n\n
