Yes, these things will be rendered insignificant in the fullness of time, but as a human's with limited lives, it's still important to maintain empathy towards the human suffering of the here-and-now, and the very near future. It will be painful, it will be stressful, and we need to brace ourselves for the reality that many of our fellow humans will die from famine, regional war, and refugee crises whilst we struggle to adapt to and mitigate the worst of it.
Well at least we are unlikely to starve: satellite imaging shows very significant greening of the planet in many areas previously barren. How so? As the Ontario Ministry of Agriculture, Food and Rural Affairs puts it,
“The benefits of carbon dioxide supplementation on plant growth and production within the greenhouse environment have been well understood for many years. For the majority of greenhouse crops, net photosynthesis increases as CO2 levels increase from 340–1,000 ppm (parts per million). Most crops show that for any given level of photosynthetically active radiation (PAR), increasing the CO2 level to 1,000 ppm will increase the photosynthesis by about 50% over ambient CO2 levels. For some crops the economics may not warrant supplementing to 1,000 ppm CO2 at low light levels. For others such as tulips, and Easter lilies, no response has been observed."
But this means more carbs in plant and less proteins, the diluted nutrients is said to be cause of bees dieng off, as they eat pollen for their protein needs and pollen has less protein, because plants dillute it with all that extra carbohydrate productions caused by more co2 in atmosphere
