NOAA radiosonde data shows that global warming is nonsense. Temperatures took a dip in the 1970’s, and then returned to their earlier levels.
This is identical to what NASA US temperatures showed, before they started tampering with the data.
It is also what the National Academy of Sciences showed for the Northern Hemisphere, before NASA and NCDC started tampering with the data.
There isn’t one smidgen of truth to this scam. The people behind it are either incompetent, severely duped, or they are crooks.
