Hi Mai, thanks for watching!😎👍

You sure about the rainfall Alan? Done nothing but rain all winter down here, had to cover my outside cactus bed for the first time. CO2 has risen by 0.02% in the past 200 years but it's been thousands of times higher in the past when plants grew huge like the coal measure ferns the size of trees. Might be a factor, but nitrogen fixation by thunderstorms is a more likely culprit in the short term, grass grows mental 4 days after a thunderstorm. We tend to notice it when we've got 3 acres to cut 😬😁

Agreed about the nitrogen,, but CO2 has risen at a very rapid rate in a short time. The earth itself is producing more chlorophyll to counteract this. This well-referenced article in Vox shows how this is happening. www.vox.com/down-to-earth/2024/2/7/24057308/earth-global-greening-climate-change-carbon If we are heading towards Jurassic World 2 it doesn't worry me, life and humans will adapt. Thanks for watching, Ziggy 🌲🌳🌴

@@newbotany Good thing it has Alan 🙂 Only needed to go down below 150ppm and we wouldn't be typing this now as all the plants would be dead along with us 😮 I'm just reading a book called "Underland" which tells about the 10,000 year old cave full of human skeletons found in the Medips, they were all suffering from chronic malnutrition. I know it was in the ice age but I also wonder how much of that was due to plants declining as the CO2 was so low then? 😬 Yep, roll on Jungle Britain, good to have food to eat 🙂
