The scientific evidence says overwhelmingly that human activity is
contributing to climate change. It's that simple.

I also notice that just today that is yet again supported by the latest
evidence out of Hawaii.

Ay yup.

An instrument near the summit of Mauna Loa in Hawaii has recorded a
long-awaited climate milestone: the amount of carbon dioxide in the
atmosphere there has exceeded 400 parts per million (ppm) for the first
time in 55 years of measurementand probably more than 3 million years of
Earth history.

it's not that the trend is going up that is
bad, but the trend looks to be going faster.

if that is because the ocean can no longer
soak up as much CO2 or for other reasons i'm
not sure.

In part it is that CO2 is the driver, but that water vapor, and methane
are playing a rapidly increasingly role in Climate Change/Global
Warming. It's not just one genie that needs to be put back into the
bottle. Even if we did control CO2, water vapor, and methane will
continue Climate Change/Global Warming. We are acting like the frog in
the heating pot of water.
