To feed billions "more greenery" is not sufficient, you need reliable and predictable weather. Just one or two years of world-widespread crop failures can cause mass famine. Even if on average "it's getting greener". The temperature during last 10k years varied still much less than long periods before and we're now already outside that band. For example:

You are probably mixing weather and climate, but none of them has ever been predictable with or without human input. I don't think your graph is saying what you want it to say. Crop failure is a fact of farming and on average is getting less and less common, otherwise the earth would not be getting greener.

Death Valley recently got greener thanks to occasional flash floods. So you say it will be america's breadbasket? Not with such extreme weather. And as temperature gets up, weather extremes will too.

I do hope you differentiate between greener on average for the whole planet and a local phenomenon. The Earth had the richest flora and fauna when it was the warmest. Why would I believe your scary speculations instead of proven scientific data?

[rini17]

It is scientifically proven that every food is grown in some local conditions with local phenomena. Global averages are relevant only how they affect these local conditions. When global average climate changes, local phenomena become more erratic. That's not some scary speculation. Unless you have serious research on contrary? How can you be so sure there's not going to be heatwaves, floods, etc. that cause havoc in enough locales to affect world food security?

If on average the Earth is getting greener, this doesn't mean everywhere on Earth is getting greener the same amount. Some places may become less green, some may stay the same and some may become much greener. But on average more places are getting greener than not. Therefore global output is increasing!

Historical data shows Earth was greener and had larger animal mass when it was warmer. If you think this time things will be different, you should present evidence confirming your position.

Which historical data? For example the hottest period ever was during time of Pangaea supercontinent, which was largely desert.
