CO2 is plant food....we need more plant food.....there's a food crisis.... 
anyway CO2 has very little to do with "climate change" whatever you perceive climate change to mean.....anyway.......do carry on
The world is gradually becoming less green, scientists have found. Plant growth is declining all over the planet, and new research links the phenomenon to decreasing moisture in the air—a consequence of climate change.
The declines challenge an argument often presented by skeptics of mainstream climate science to downplay the consequences of global warming: the idea that plants will grow faster with larger amounts of carbon dioxide. The argument hinges on the idea that food supplies will increase.
It’s largely a red herring, as climate scientists have patiently explained for years. Rising CO2 does benefit plants, at least up to a point, but it’s just one factor. Plants are also affected by many other symptoms of climate change, including rising temperatures, changing weather patterns, shifts in water availability and so on.
Funny that. Increased water vapor in the atmosphere amplifies the warming caused by other greenhouse gases. It works like this: As greenhouse gases like carbon dioxide and methane increase, Earth's temperature rises in response. This increases evaporation from both water and land area climate.nasa.gov/explore/ask-nasa-climate/3143/steamy-relationships-how-atmospheric-water-vapor-amplifies-earths-greenhouse-effect/#:~:text=Increased%20water%20vapor%20in%20the,caused%20by%20other%20greenhouse%20gases.&text=It%20works%20like%20this%3A%20As,both%20water%20and%20land%20areas. |

For nearly two years the general populace were prevented from spending their money as they wished. No holidays. £4000/yr No new car. £1500/yr No meals out. £1200/Yr No traveling to work. £1000/Yr No days out/entertainment. £2000/Yr Etc, etc, etc..... And then, all of a sudden that accumulated cash can be spent freely. Shock, horror, inflation! No shit sherlock. Spending money fuels inflation??? Suddenly spending billions of newly printed money — that's been dished out in sackfuls to combat a pandemic, to put food on family tables, keep companies afloat, etc, but hoarded by many — on too few goods and outlets, pushes up prices.
If supply catchers up with demand — or demand lessens with the realisation certain expenditure is no longer possible — inflation may fall and, perhaps, prices may follow...

What's funny?
The increasing amount of water vapour in the atmosphere — caused by global warming — is depleting the amount of water available to vegetation on the ground.
Increasing CO2 is contributing to global warming. Global warming is increasing the amount of water that is vaporised and held in the atmosphere.
As your link puts it:
As greenhouse gases like carbon dioxide and methane increase, Earth’s temperature rises in response. This increases evaporation from both water and land areas. Because warmer air holds more moisture, its concentration of water vapor increases. Specifically, this happens because water vapor does not condense and precipitate out of the atmosphere as easily at higher temperatures. The water vapor then absorbs heat radiated from Earth and prevents it from escaping out to space. This further warms the atmosphere, resulting in even more water vapor in the atmosphere. This is what scientists call a "positive feedback loop." Scientists estimate this effect more than doubles the warming that would happen due to increasing carbon dioxide alone.
It would seem that the most effective way of combatting global warming is to reduce the amount of CO2 and methane getting into the atmosphere, thereby cooling the atmosphere and lessening the amount of water vapour it can hold...

Your post claims that water vapour is decreasing . My link claims it is increasing . I don’t deny that you may be right . |

Where do I claim water vapour is decreasing...?
PS — "moisture in the air" appears to be the culprit. I guess it depends on whether available moisture is considered to be precipitated water vapour or not...

Apologies, see my post above.
Not being a scientist, I see "moisture in the air" as something that condenses as it touches anything. But I visualize water vapour in the atmosphere as something way up there like a blanket, remaining until the atmosphere cools and the vapour returns to its liquid state (bet I've got some terminology there wrong too)...

Indeed. I suppose global warming could cause humidity to decrease over large land masses. |

But it is not just the sceptics. NASA say the planet is greener and global warming is a human effect. If only we knew who to believe and who is right which is a peculiar place to be in since the science is settled and has been for some time apparently. www.lonelyplanet.com/news/nasa-study-green-planet |
