Yeah, we're doomed, and I'll give you five simple reasons why. 1. ~60% of fossil fuel emissions stay in the atmosphere, and CO2 levels have spiked from 280 ppm in the 1950's to 400 ppm today. We are on track to reach 1500 ppm in the next hundred years. 2. When CO2 dissolves in water it combines with water molecules to form carbonic acid, and the oceans have already become 30% more acidic in the past century. 3. Photosynthetic algae and plankton absorb CO2 through photosynthesis, then drag it to the ocean floor when they die, but as the oceans become hotter and more acidic their populations are shrinking, and they simply dissolve the CO2 back into the water when they die. 4. Optimal photosynthesis needs temperatures around 20 c, and the chemical reaction slows down and stops above 40 c. 5. Agricultural civilization is still completely dependent on fossil fuels. It doesn't matter how efficient a solar panel is when you still need hundreds of millions of barrels of oil to grow, harvest, process and distribute food.
