@RobertWager1 @PaulRoundy1 @GrahamLKeegan The IPCC concludes that anthropogenic forcing is the dominant driver, which is correct. That doesn't mean nothing else can affect short-term variability.

Is there any natural force which you think the IPCC hasn't considered?

Shewchuk, please answer these questions about your cartoon meme.

1. What peer-reviewed evidence & data supports your invented “Bray & Eddy Composite Solar Cycle” curve?

2. Why did you use a smooth hand-drawn sinusoid instead of actual solar irradiance data?

3. Why are there no units, scales, error bars, or methodology shown?

4. Why does your graph imply modern warming is solar-driven when satellite data show no long-term increase in solar output since the 1970s?

5. Why omit that global temperatures kept rising while solar activity flattened or declined after 1950?

6. If the Sun is causing modern warming, why is the stratosphere cooling while the lower atmosphere warms?

7. Why include Milankovitch cycles when they operate over tens of thousands of years, not decades?

8. Why present the Medieval Warm Period and Little Ice Age as globally uniform events when the evidence shows they were regionally variable?

9. On what scientific basis did you extrapolate the red curve into the future and place the next peak around 2130?

10. If this graph is “not actual temperatures,” why label it with historical warm and cold periods to imply it reflects real climate history?

11. If we are merely “thawing out” from the Little Ice Age, why did temperatures stop cooling and abruptly accelerate upward at the same time greenhouse gases rapidly increased?

@Gilles_Borghese @marco_borrano @CaptainAdvance1 @4RealClimate @blizzard219 @joseph_postma @Ernestops78 @ryankatzrosene I didn't post the result of a model. I posted data from CERES satellites.

Are you blind as well as stupid?

[David Coates @djcoates_]

@Gilles_Borghese @marco_borrano @CaptainAdvance1 @4RealClimate @blizzard219 @joseph_postma @Ernestops78 @ryankatzrosene There is an energy imbalance, as measured by satellites and by OHC.

[David Pocock @DavidPocock]

Australia has led the world on rooftop solar, and we can do the same if we continue this with batteries - lowering energy prices for every 🇦🇺n.

Credit to Dr Helen Haines for pushing for a household battery scheme for years and Minister Bowen and the govt for implementing it.

We have to ensure that lower income households and renters also benefit from electrification and the $1000s of dollars it can save households every year.

@ObliqueOrder @brad_polumbo Do you think it's a good thing that the DoJ is spending its time and resources bringing bullshit indictments, rather than prosecuting actual crimes?

[David Coates @djcoates_]

There is a reason you can't answer a simple yes / no question.

You're now introducing a completely different model of albedo-driven warming, which is an acknowledgement that the TSI model breaks down for recent warming.

The albedo model is also wrong, for multiple reasons:
1) The measured decrease in albedo explains some, but not all, of the modern warming trend.
2) Much of the change in albedo is a feedback of CO2-driven warming, e.g. global ice cover loss.
3) Nikolov (who created this chart) has no explanation for what is driving the change in albedo. For example, we know it's not GCRs: https://t.co/7y1DXG4dIQ

@socratesccost @ClimateSageO You didn't answer the question, so I'll ask it again.

Satellite TSI measurements since 1980 show a flat to slightly declining trend. By your own model, the rise in temperature should now be slowing. Is it?

[David Coates @djcoates_]

@socratesccost @ClimateSageO Cherry-picking two free parameters until the curves match is curve fitting, not good science.

Satellite TSI measurements since 1980 show a flat to slightly declining trend. By your own model, the rise in temperature should now be slowing. Is it?

@APLSceptic @Ceist8 @_ClimateCraze Is the Earth 78.6C or 109.5C?

Why do deniers never actually read what they post?

[David Coates @djcoates_]

@JamesBurnsCa @RichardHanania Why can't Trump or those around him acknowledge that it was a mistake?

[David Coates @djcoates_]

@Liveleigh1 @Ceist8 @trucmuc28502451 @DrJamesEHansen Nitrogen doesn't interact with IR at all (at Earth pressure), so its relative abundance is irrelevant when it comes to the greenhouse effect.

[David Coates @djcoates_]

@CervixCowboy @ibaird @thematrixb0t @jmil400 The Ozone hole has been recovering for decades precisely because the world got together with the Montreal Protocol and phased out CFCs.

Acid rain was solved primarily due to reductions in SO2 emissions after legislation in the US, Canada, and the EU.

[David Coates @djcoates_]

@cliff_mcqueen @CaptainAdvance1 @PeterDClack That's a tortured analogy. You can't quantify how "blue" a photon is. You can also move away from blue in two directions, not just one.

[David Coates @djcoates_]

@ryankatzrosene Don't be rude, Ryan. Climate astrology is a serious and completely legitimate field of pseudoscience.

[David Coates @djcoates_]

@Ceist8 @TheDisproof @_ClimateCraze Shewchuk posting junk charts?

Say it ain't so!

[David Coates @djcoates_]

@_ClimateCraze John, why are you running?

[C e i s t @Ceist8]

Shewchuk -some questions for you:

1. Why are you averaging raw absolute maximum temperatures instead of anomalies (each station’s deviation from its own long-term baseline)?
Every climate dataset on Earth uses anomalies precisely because raw absolute temperatures are dominated by fixed geography - things like elevation, latitude, and local terrain that never change.
Your “dumb average” is scientifically worthless for trends.

2. As a retired meteorologist and former NWS COOP observer, why do you completely ignore the Time of Observation Bias (TOB)?
The documented shift from afternoon to morning readings cooled the raw record by ~0.3 C.
That alone explains most of your flat “raw” line.

3. Why does your “raw” chart never match the official unadjusted USHCN TMAX data when properly processed as anomalies?

4. If NOAA’s adjustments are “fraud,” why does the pristine, bias-free USCRN network (installed since 2004 with no TOB or siting issues) match the adjusted USHCN trends and anomalies almost perfectly, but diverge from your raw data?

5. Your chart only shows US maximum absolute temps.
Why does your “raw” claim disappear when you look at minimum temperatures, global datasets, satellites, reanalyses, or ocean heat content, all of which show clear warming?

6. Can you post your exact code and the specific USHCN version/date you used so independent analysts can reproduce your “raw” flat line?

@Australian94152 @Diver_Flemming @GreenLifeMaps 🤭

[David Coates @djcoates_]

@Australian94152 @Diver_Flemming @GreenLifeMaps Not really. Your chart is simply showing the magnitude of surface fluxes for one location on one day. As CO2 concentration increases, the "Net IR" curve shifts upwards (less negative).
