IPCC finally vindicated: Over 50% of global warming is Mann-made

A post by Steven Goddard today shows how James Hansen's GISS data was tampered to create 0.35C artificial global warming. Since the total alleged global warming since 1850 is only 0.7C, this single tamper alone accounts for half of that trend. So, in a sense, the IPCC attribution statement is finally vindicated with 95% confidence that over 50% of global warming is Mann-made.

Hansen’s 1981 Remarkable Conclusion

Hansen wrote this in 1981
A remarkable conclusion from Fig. 3 is that the global temperature is almost as high today as it was in 1940.
At the time, he showed 1980 temperatures about 0.15C cooler than 1940.

Now, NASA shows 1980 temperatures about 0.2C warmer than 1940. They made a relative shift of  0.35C, far exceeding Wigley’s hoped for 0.15C
