reflect sunlight, the smaller
cloud cover allows plants to receive much higher radiation, increasing evaporation and photosynthesis rates, another process missed

Recently observations of the light
reflected by these planets provided insight on the
cloud distribution on the dayside of these planets: for a handful of planets
clouds seem more abundant on the western than on the eastern side of the dayside hemisphere and, more importantly, this asymmetry depends on the equilibrium temperature of the planet.
A team of scientists led
by Pacific Northwest National Laboratory atmospheric researcher Dr. Susannah Burrows and collaborator Daniel McCoy, who studies
clouds and climate at the University of Washington, reveal how tiny natural particles given off
by marine organisms — airborne droplets and solid particles called aerosols — nearly double
cloud droplet numbers in the summer, which boosts the amount of sunlight
reflected back to space.
The

by reflecting solar energy or trapping terrestrial radiation.
The simulations confirm that aerosol injection does brighten

by burning fossil fuels.
Brighter

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth
by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to

clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise
by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).
This includes the energy trapped

So, the question of whether or not more of these
