OK how does science update observations without a time machine?
Observations are observed facts and by their nature do not
change unless a calibration was found to be incorrect and
then it is not the observation that changes it is the computed
result after application of calibration data.
I am a believer in global warming and global climate change.
I am not a believer in much of the "science".
I balk at consensus science.
My personal bias has many origins but the one the gets me
was a "customer" complaining that his new supercomputer
was giving him an incorrect 19th digit in the resulting output.
I cracked open the deck (old FORTRAN) and noted on the
first screen "PI = 3.14". This tells me that NOTHING in
the output that involved PI had any validity beyond three digits.
Yet this guy was concerned with the 19th.
I asked why he did not substitute a value of PI from math.h
and he explained that the code was unstable if given more
digits to PI. OMG I said to myself.
Then I looked at his published research and yes he was worried
about CO2 in the ocean but in specific he wanted to eliminate
natural regions of the sea floor low enough in O2 to sequester
organic matter. i.e. he was worried about a natural process that
reduced CO2 in the air and wanted to eliminate it.
I happen to live down wind of "El Niño" and am astounded by the inability
of the global weather services to model and measure this. I see
headlines like: ""El Niño might “push the needle on global temperature” toward unprecedented warmth""
This is a conjecture for the 2015-2016 rainy season in Calif less than a year away
and others are telling me that the sky is falling in 100 years.
Like I said I am a believer that man is altering the planet weather.
I do believe that the ostriches in government need to fund quality
research and fund better data gathering efforts.
The United nations needs to mandate that all commercial aircraft, trains and all ships at
sea carry an instrument package to assist in data collecting efforts.
And that that data be delivered to the UN for use by all UN members.
This does leave big data voids but it would be a start.
