Climate Databases are still a mess

Dog bites man:
Virtually all of the USHCN warming since 1973 appears to be the result of adjustments NOAA has made to the data, mainly in the 1995-97 timeframe.
We've seen this before:
An interesting question is how much of the 20th century's temperature change is due to adjustments? As it turns out, the answer is all of it.

This chart shows the before-adjustment and after-adjustment temperatures for the 20th century, super imposed. All of the warming is due to adjustments, rather than raw data. Almost all of the adjustments are for readings after 1970.


Color me skeptical on the ZOMG Thermageddon panic. I would love for a clear explanation on the adjustments.  And I'd be a lot more sympathetic to the argument for warming if the warming didn't all evaporate when you just look at the original, unaltered data.

Agreed. And also if Warmists didn't keep putting their thumbs on the scale in hopes of stampeding everybody into the Warmists' favorite policy actions.

By now the entire climatology community has essentially destroyed its credibility as a science with the general public. It is going to take them a generation or more, plus being totally forthcoming about their measurements and their errors, before anyone can trust them again.

This is actually a good working definition of science, but we'll see how fast the community cleans house. I'm not holding my breath.

Anon there's an old saying that for any branch of science to advance, the previous generation of scientists has to die off.

I expect that the public will start trusting climate science more when the stakes become a lot lower.

If you look at who would be making LOTS of money off of "climate change" then you can see why it's being pushed so hard & by whom>

On gordo's line of thought: It was Enron that dreamed up the cap and trade scheme.
Enron attempted to hedge broadband service no less. The smartest shysters in the room.
