Information: 
 A climate model predicts temperature (  ) using three variables: CO₂ concentration (  ), methane concentration (  ), and total greenhouse gas index (  ). Historically,    (strong linear relationship). The prediction system    where    shows unstable predictions. 
Why does the strong correlation between    and    cause prediction instability?

Answer

Strong correlation ensures accuracy since variables move coherently; instability means bad data

Answer

Redundant information makes the system overdetermined, requiring least-squares for stability

Answer

Eigenvalue clustering near zero triggers power iteration instability in Krylov-based solvers

Answer

Near-linear dependence in   's columns causes large   , amplifying small measurement errors into huge prediction errors

Answer

The relationship    makes    exactly, so regularization is needed

Answer

Time-series autocorrelation in climate data violates assumptions needed by linear solvers
