There's a lot of carbon created each year, and one of the solutions some engineers are coming out with is to genetically engineer trees.

Making nature absorb and convert it into a more long lived less environmentally dangerous form makes a lot of sense. Trees, plants and algae do some of this work in photosynthesis, but we humans currently produce way more atmospheric carbon that nature can deal with alone.

One idea is to increase a tree's natural absoprtion rate of light and the amount of carbon it absorbs allowing trees to sequester more carbon in their roots instead of releasing it back into the atmosphere.

Another idea is to boost the quality of the crops themselves, making them better suited for use in bioenergy and thus reduce our dependence of fossil fuels.

These ideas are examined in the October issue of the journal Bioscience, and you can read some of it over here.
