whoa back up the truck little buddy...the claim is CO2, not water vapour, not CH4...CO2...once again you can't even get your own religion correct.
Quote me where I wrote that.

No one is saying they are not green house gases...I never said anything of the sort. The question is why don't they consider the sun? water vapour? because the IPCC rejects them all because man doesn't create those..
but this little CO2 thing? hum we can use that....
You write that like the IPCC is one unified group. They are in fact, a group ov volunteers that compile reports from various sources. And, which report from 2016 again?
And CO2 is not useful if the plants are not adapted to use it. This study mirrors many others looking at the same thing.

The prevailing view among scientists is that global climate change may prove beneficial to many farmers and foresters -- at least in the short term. The logic is straightforward: Plants need atmospheric carbon dioxide to produce food, and by emitting more CO2 into the air, our cars and factories create new sources of plant nutrition that will cause some crops and trees to grow bigger and faster.
But an unprecedented three-year experiment conducted at Stanford University is raising questions about that long-held assumption. Writing in the journal Science, researchers concluded that elevated atmospheric CO2 actually reduces plant growth when combined with other likely consequences of climate change -- namely, higher temperatures, increased precipitation or increased nitrogen deposits in the soil.

IF that was the case then why do ice cores show much lower temps with much greater Co2 levels in the past?
When, exactly?

How does Co2 explain the medieval warming period? I could go one... you can't have it both ways....
It was a local anomaly, not a global event.

water vapour out numbers Co2 in the atmosphere by orders of magnitude and it's 'green house gas' effect is also orders of magnitude greater than Co2 yet..nope not going to use that...

sure...keep digging your hole...keep kidding.
It must cause you physical discomfort to be this wrong this often.
