1: warmer air means less cloud cover, so greater heat gain because we have less reflection from the top of clouds... with less cloud cover we get fewer but heavier rainfall events, not as well distributed, so we get localized flooding events and widespread drought events.
2: Oceans will absorb and retain less CO2, meaning that warming effects of CO2 will increase.
3: Many plants will shut down their photosynthesis during a longer time in the day, meaning less food production even when there is water, far less if there is drought or flooding.
4: If people do not make accommodations, we will see more people suffer and die during heat waves... Note, this is a conditional effect.
5: Eventually far northern areas may support life a bit better, and then,
Far southern areas, Antarctica, will continue to receive large amounts of snow from oceans covered with volumes of water vapor, but the temperature will continue to rise. Eventually the precipitation will be falling as rain on coastal Antarctica. At that point glacial melt will begin in earnest, severe cooling of the southern hemisphere, even large areas of the northern hemisphere. Oceans will be receiving volumes of fresh, cold water that stays on the ocean surface.
This event is a major reason it is described as climate change and not just global warming.
6: as the oceans become warmed up, they will support a major new period of cloud cover that goes over most of the world, causing cooling, and rain, changing to heavy snows in the north, and an ice age.
