Correct answers: tree rings and ice formed thousands of years ago.

- Tree rings: ring width and density record growing-season conditions (including past air temperatures).
- Ice cores: oxygen isotopes and trapped gases in ancient ice preserve past atmospheric temperatures.

(Foraminifera isotopes record seawater temperature; fossilized pollen indicates vegetation/climate broadly but not direct air temperature at formation.)
