  No - it means that the solar wind is affecting the atmosphere enough that a greenhouse effect on Mars is not getting started, even though it could if there was a magnetic field on the planet. This means the solar wind effect is not negligible. An artificial magnetic field plus other means could have a drastic and extremely rapid (in geologic terms, hundreds of years) effect on Mars climate.
