If growth continues at this pace, Hibbs's model would project Obama to garner a little greater than 44% of the vote.

Nonetheless, scientists are confident that models can project big-picture changes such as global temperature rise.

This model projected 4,900 stars, and was limited to showing the sky only from Jena's latitude.

Turnout is key, and pollsters use different models to project the likely electorate.

This model projects the lives of fictive individuals as a base for pension amount calculation.

The other model projected a climate like Atlanta's, a full 10 degrees warmer than Boston's, according to the report.

All models project a temperature increase by about 1-1.3 C by 2050.

If models incorrectly project future changes in the carbon cycle, then concentration or temperature targets could be missed.

Five models were projected; the first, and as it proved only, to be built was a prototype of the largest, the model 4-S.
