Consider How might ecosystems be affected if levels of atmospheric CO2 continue to rise?

Rising CO2 levels affect a lot of plants directly by stimulating photosynthesis and reducing the loss of water (plant transpiration) by reducing the opening of the small pores in the leaves, known as 'stomata'. This triggers several more subtle, indirect effects

Explanation:

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude
