Jakosky and Edwards inventoried CO2 reservoirs on Mars and concluded there is not enough accessible CO2 for significant greenhouse warming, so terraforming Mars is not possible with present-day technology.
As reported in: Jakosky, Edwards (2018). Inventory of CO2 available for terraforming Mars. Nature Astronomy. doi:10.1038/s41550-018-0529-6
Wordsworth, Kerber and Cockell showed through experiments and modelling that a thin layer of silica aerogel could warm regions of the Martian surface via a solid-state greenhouse effect, making them habitable to photosynthetic life.

Ansari, Kite and Ramirez modelled artificial aerosols such as ~9-micrometre conductive nanorods made from Mars materials, finding they could warm Mars more than 5,000 times more effectively than the best greenhouse gases.
