IMO, the warming trend, if it is in fact real rather than a
statistical artefact, is overwhelming natural.
According to Occam (.... the simplest explanation is the most
likely), it IS most likely to be natural.
Actually I'd have thought the simplest explanation is that we're
causing
it rather than completely coincidentaly the earth has embarked upon a
warming trend in line with rising CO2 levels from human activity.

Your comments betray a deep ignorance of climate - and particularly CO-2.
CO-2 is a minor greenhouse gas and human production of it is utterly dwarfed
by natural sources.

No it isn't. There is a large natural flux flowing round the system but
we are releasing enough CO2 by burning fossil fuels to measurably alter
the isotopic composition of CO2 in the atmosphere. See for example:

And also to alter the CO2 concentration in the oceans making life rather
more difficult for calcium fixing corals.

And to measurably alter the O2 concentration now that routine
measurement devices with close to 6 figure accuracy are available.

I suggest you get yourself a basic scientific education before spouting
ignorant crap on a subject about which you clearly know nothing.

It is you who need a decent science education. Relying on Exxon
sponsored denialist websites will not hack it.
