Using hot air balloons as sun shades would be much cheaper than satellites in high orbit. And balloons would give more flexibility as they can be used to heat the air above clouds and disperse them when needed. But most importantly they can be used to improve actual weather, so even the people that are not interested in abstract climate change would support them.
