Scientists don’t use the start date of the 1970s to look at Global Temperature trends as evidence of AGW – –as you say, that’s too short a time frame. They start when fossil fuel burning started to pick up –typically, mid 19th century or a little later.

True “scientists” know that atmospheric CO2 was NOT influenced by man’s contributions until 1945. Show me your values that show man’s release of CO2 significantly affected total atmosphere ppmv prior to 1945.
Temperature increases in 1840 – 1870 were almost as fast as those between 1915 – 1940, and 1915 – 1940 was the same as 1975 – 1996.

A strong comment for consideration and change!
The first seven plots are clear with respect to source institute and range of plots. Very compelling information.
BUT! But the titles below each plot (that part of the web page that we (you) are able to edit as a permanent label to the linked institution’s ever-changing web page) needs to include the reference period for each: 1970-1990, 1960 – 1980, 1990-2000, etc. Without thaose different reference dates, the apparent differences between each of the seven temperature records becomes very, very confusing. Is May 2014 +0.17, 0.75, 0.50, 060, 0.25 degrees?
2. You knew there had to be a “2” didn’t you?
Add please the Antarctic long term temperature trend (it has been negative for many years!) below the long term Arctic trend. That source can be the same as on the Sea Ice page.

Let me ask again.
What exactly do YOU calculate as man’s contribution to the earth’s CO2 level in ppmv at the following dates:
(1) 1800 –
(2) 1890 –
(3) 1915 – When warming began
(4) 1945 – When cooling began again
(6) 1975 – When CAGW warming began
(7) 1996 – When CAGW warming stopped
What was the increase in global average temperature based on that change in CO2 on each of those dates?

@RACook:
You asserted that the CO2 rise cannot be attributed to man. Show your evidence that invalidates that it has.

FALSE!
I told YOU to show by specific evidence HOW MUCH of the CO2 increase at each of seven specific dates was due to man’s release of CO2.
YOU are the man demanding tens of thousands of innocents die because YOU want to unnaturally and artificially restrict CO2 emissions worldwide. “I” am merely trying to get YOU to admit in public exactly how little of the CO2 increase that did occur was emitted by man at those specific dates earlier in history. YOU refuse to provide those values because those numbers prove YOUR theory is wrong.

Mainstream science conclusions are similar, but not as black and white as yours. The analysis and evidence shows anthropogenic contributions as non-zero, and less than natural forcings up to around 1945. After that, anthropogenic forcings accelerate.

See! I agree with you.
Now, WHAT WERE THOSE CONTRIBUTIONS before 1945 due to Man’s release of CO2? Nothing else. Just man’s CO2 release.
That is, after all, why YOU are demanding the death of millions more innocents each year between now and 2100 – to stop the future releases of CO2 into the atmosphere. If today’s releases of tens of billions of tons each year for 17 years have no effect on temperatures, surely you have some evidence somewhere that 1/1000 of that much CO2 released over 50 years had – what “more” effect on global temperatures? If satellite measurements “prove” a release of tens of trillions of tons of CO2 into the air between 1979 and 2014 increased global temperatures by 1/5 of one degree in 45 years, surely the release of 1 million, 10 million, 100 million, or even 1 billion tons of CO2 between 1800 and 1945 would be demonstrable, right?
Surely you do not condemn millions to death for no reason but the “hand waving” of your so-called experts, do you? What are those numbers: How much do you believe temperature rose each year prior to 1945 due to man’s release of CO2 between 1800 and 1945?

Funny, these things called numbers.
Odd that the so-called warrenlib refuses to even do the math.
But, to support the arthimatic involved, I did start by looking up the mass of the earth’s atmosphere:
and, you know, you’d figure after 200 billion of paid research, we would know how much of the stuff is there.
But, no.
Got the following after a few minutes looking:

4.99 x 10 ^18 kg
5.0  x 10 ^18 kg
5.0  x 10 ^18 kg
5.1  x 10 ^18 kg
5.12 x 10 ^18 kg
5.2  x 10 ^18 kg
5.2  x 10 ^18 kg
5.27 x 10 ^18 kg
5.3  x 10 ^18 kg
5.4  x 10 ^18 kg
5.5  x 10 ^18 kg

Now Trenberth, NCAR, in 1994 wrote up 5.1441 x 10^18 kg, but then NCAR corrected that value and is now using 5.1353 x 10618 kg. Since Trenberth has not been found correct before, I’m tempted to go with the NCAR number as the most accurate answer – because, obviously, it is the one with the highest number of digits!
Thus, if warrenlib agrees, we will use NCAR’s 5.1353 x 10^18 kg as the atmospheric mass.
More important, then, can all readers agree that N2, O2, and Ar are the most important non-IR absorbing gasses?
If so, can we consider them constant while looking at the small number of tons of CO2 emitted by man?
If so, would all readers check the following, since warrenlib apparently cannot?

      ppmv  mass pct  total mass
N2 780,840  75.3      3.866  x 10^18 kg
O2 209,460  23.1      1.1886 x 10^18 kg
Ar   9,340   1.288    0.0661 x 10^18 kg

From this starting point, and the data in the graphs above on this page that assume a pre-1800 CO2 level of 280 ppmv, we should be able to determine how many ppmv’s of CO2 were emitted by man at any particular year in question, right?
