For the first time since humans have been monitoring, atmospheric concentrations of carbon dioxide have exceeded 410 parts per million averaged across an entire month, a threshold that pushes the planet ever closer to warming beyond levels that scientists and the international community have deemed ‘‘safe.’’
The reading from the Mauna Loa Observatory in Hawaii finds that concentrations of the climate-warming gas averaged above 410 parts per million throughout April. The first time readings crossed 410 at all occurred on April 18, 2017, or just about a year ago.
Earth’s atmosphere just crossed another troubling climate change threshold

* m2 stares at the monitor... it looks like a hamburger...
m2 - that's a bad sign

Plants grow better now. Our world is becoming greener due to the extra carbon dioxide. This makes our farms more productive.
It helps phytoplankton too, at the base of the marine ecosystem. We get more fish to eat.
If the climate warms, well, look at a globe. Lots of land is in Canada and Russia. Even just looking at the USA, Alaska is bigger than Hawaii. More land becomes available to grow food.

Different land, not necessarily more land. Which, along with the loss of the heavily populated lands near the sea and sea level, is precisely the problem that climatologists keep warning about.

And what do climatologists know about human migration patterns, economic trade-offs, and agricultural yields which keep rising? Do their models show that the weather gets more moderate when CO2 "insulation” is added to the atmosphere? Why not? Storms are driven by thermal gradients, and insulation reduces these gradients. Seems they have built an industry out of garbage in / garbage out computer models.

I'm excited about the prospect of the new vegetables and cereals that you have cultivated for 10000 years and that are able to thrive and yield harvest on Greenland bedrock and on thawed permafrost rotting peat bogs [wikipedia.org]!
What are you going to plant in the Batagaika crater [sciencealert.com]? Might be a bit difficult to access with a tractor, so you'd need to become a spelunking farmer I guess.
Any good Sphagnum peat moss [wikipedia.org] recipes? Seems it's mostly used for non-edible purposes.

Any cellulose is a polymer made of sugars. The ways to convert it into human-digestible foodstuffs are many and varied; a fraction of the money going into promoting the narrative of The Impending Doom (tm) would solve everyhuman's food problems many times over.

The problem is, fear is more profitable commodity than food.

Carbon dioxide isn't a very restrictive bottleneck for plant growth, other nutrients are (you see this where fertiliser wash out takes place). Also, lots of non-food organisms (e.g. pests) might outcompete the food sources.
