Ocean warming could drive heavy rain bands toward the poles

In a world warmed by rising atmospheric greenhouse gas concentrations, precipitation patterns are going to change because of two factors: one, warmer air can hold more water; and two, changing atmospheric circulation patterns ...

Asian ozone pollution in Hawaii is tied to climate variability

(Phys.org) —Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found that shifts in ...
