You have google, the same as I do. Find them yourself. However, others have checked out the data with the intent of demonstrating the errors, and their results are below.

Berkeley Earth Surface Temperature (BEST) Study Results Confirm Global Warming
First day of Spring!
Joe Romm, who runs the well-respected Climate Progress blog and Twitter, just posted this -hot-off-the press item: Exclusive: Berkeley temperature study results confirm the reality of global warming and support in all essential respects the historical temperature analyses of the NOAA, NASA, and HadCRU.
Thanks to friend Mark Boslough of Sandia National Laboratories for alerting me to this.
Romm writes that climatologist Ken Caldeira sent him this note:
I have seen a copy of the Berkeley groups draft paper, which of course would be expected to be revised before submission.
Their preliminary results sit right within the results of NOAA, NASA, and HadCRU, confirming that prior analyses were correct in every way that matters. Their results confirm the reality of global warming and support in all essential respects the historical temperature analyses of the NOAA, NASA, and HadCRU.
Their analysis supports the view that there is no fire behind the smokescreen put up by climate science deniers.
The Berkeley group (BEST) - the Berkeley Earth Surface Temperature Study - was created to take an objective look at all the temperature data of Earth to assess whether global warming is occurring or not. Others felt BEST was out to debunk global warming.
Romm continues:
In one sense, this finding isnt news, since there have never been any credible challenges to the surface temperature data other than the smoke blown by the climate science deniers.
Indeed, we have very good reason to believe the data that were attacked the most, that collected by the Hadley Center and Climate Research Unit (CRU) of the University of East Anglia, (unintentionally) lowballed the rate of recent warming (see The deniers were half right: The Met Office Hadley Centre had flawed data but it led them to UNDERestimate the rate of recent global warming).
