What "hockey chart"? Was there a rise in global average temperature in 20th century or not? You only agree there was when it suits you.

That's the Abstract. Did you read the paper?

How about this in the conclusion on Page 3090?

She is saying more research needs to be done, and she is of course correct. It would be unusual for a paper whose text contradicted the abstract to even get sent for peer review.

Here is a chart from a paper Dr Lean co-authored in 2005, which updates and improves the chart you are relying so much on, even though it disproves the solar-temperature rise connection.



This more recent chart is much closer to the one I showed, though I am not making a big deal about differences. You are, though it does not matter a whit.

Note that these are "reconstructions" (as I pointed out) and differences are probably differences in statistical methodology and not significant.

Oh and that paper is from 1999.

Only 5 years previous to the chart, which is 8 years old. The chart above is more recent.

Figure 1: Global temperature (red, NASA GISS) and Total solar irradiance (blue, 1880 to 1978 from Solanki, 1979 to 2009 from PMOD).

So they took 2 separate time series interpretations of Solar Irradiance and glued them together to suit the needs of their propaganda.

How many times do I have to refute this fallacy?

BTW - This is the Solanki Paper, which again doesn't fare too well for the Solar Deniers.

Once would be a good start.

You can make up whatever reasons you want for disliking the skepticalscience graph but even the one you posted shows flat or declining solar activity since about 1950 with the decline being even more pronounced in recent years. Temperatures have clearly not tracked solar activity since the mid 1970s which is the mainstream scientific position.

You have not outlined exactly what it is you disagree with from owedtojoy's posting nor have you shown why his sources are wrong. This is hardly surprising since to make solar activity and temperatures match you either have to throw out the temperature data or the solar activity data.

No it isn't. It agrees very well with the Lean & Wang(2005) paper, which I post again.



But where is the evidence for your claim that solar irradiance ONLY influences climate? That is the fallacy.

So they took 2 separate time series interpretations of Solar Irradiance and glued them together to suit the needs of their propaganda.

How many times do I have to refute this fallacy?

The only fallacy around here is your claim that solar irradiance and solar irradiance ONLY influences climate. Solar irradiance is a part of natural variability, and of course influences climate, but not in the way greenhouse gases have dominated recent warming.


Solar contribution to global warming according to Meehl et al. 2004 (M04, blue), Stone et al. 2007 (S07, red), Lean and Rind 2008 (LR08, green), and Huber and Knutti 2011 (HK11, purple).

Solar activity & climate: is the sun causing global warming?

Incidentally, here is a chart from Dr Lean's paper of 2008 (with Rind, the results are above, they estimate solar irradiance makes only 10% contribution to global warming).


Lean and Rind reconstructions of the contributions to monthly mean global surface temperatures by individual natural and anthropogenic influences. The right hand axes give the native scales of each influence, and the left hand axes give the corresponding temperature change determined from the multiple regression analysis. The grey lines are trends for the whole interval. The inset in Figure 2d shows the individual greenhouse gases, tropospheric aerosols and the land surface plus snow albedo components that combine to give the net anthropogenic forcing.

Lean and Rind Estimate Human and Natural Global Warming

Remember, CS, it was you who used Dr Lean's chart to claim "inaccuracy". Why then is she writing papers that say solar irradiance is only responsible for 10% of global warming?

And she does agree there has been global warming. Do you?

Proven wrong. We can call it BS.

Weird misconception.

A new round of Arctic Ice predictions.

Note: Every single prediction (even Anthony Watts') if for an extent less than 5M km^2. The 5M barrier was only broken for the first recorded time 5 years ago, and deniers of global warming (or ice decline) have been talking up a "recovery" ever since.



In fact, ice extent is being lost at this time faster than 2007, the record minimum extent. June and July (around the solstice) are the biggest declines, and about 0.5M km^2 has been lost in the last 4 days - and average of 0.125M km^2 per day. That may last another week or so, even well into July. If it does, we may be on for a new record. However, much depends on the local weather this summer.

ABSTRACT (Lean 2000):
Because of the dependence of the Sun's irradiance on solar activity,
reductions from contemporary levels are expected during the
seventeenth century Maunder Minimum. New reconstructions of spectral
irradiance are developed since 1600 with absolute scales traceable to
spacebased observations. The long-term variations track the envelope
of group sunspot numbers and have amplitudes consistent with the range
of Ca II brightness in Sun-like stars. Estimated increases since 1675
are 0.7%, 0.2% and 0.07% in broad ultraviolet, visible/near infrared
and infrared spectral bands, with a total irradiance increase of 0.2%.

The chart obviously shows the 11yrCYCLE+BKGRND data.

But the data are going down again



Now let's take a look at the temperatures during that time:



And for the last 100 years



So the lose relationship between sun activity and global temperature has totally vanished for the last 40 years.

The main driver nowadays are greenhouse gases.



CO2 and temperature have been correlating for the last 500,000 years!



Guess what's happening despite decreasing solar activity?

What like this?




Again I refer to this post which it was claimed that the chart could not be refuted. It was debunked and exposed as a lie.

The Climate Change Debate Thread

Furthermore, that graph that I refuted is a fantasy of the Skeptical Science website, which is a blog run by a cartoonist.

About Skeptical Science

This site was created by John Cook. I'm not a climatologist or a scientist but a self employed cartoonist and web programmer by trade. I did a Physics degree at the University of Queensland and while I achieved First Class Honours and could've continued onto a PhD, I instead quit academia and became a professional scrawler. Too much doodling in lectures, I think.

The graph owedtojoy illustrated and claimed I couldn't refute is a fallacy. Deal with it.

I said Primary, not "only"

How many times can one say a tautology such as solar variance is the primary cause of climate change?

Again you are twisting what I said and ignoring the exposure of the lie. Remember this?
