For example, ice cores taken in various locations around the world (Greenland and Antarctica, for example) are excellent proxies; gas bubbles containing CO2 trapped in ancient ice can be measured, and the age can be determined very accurately (by counting
the seasonal ice layers, or measuring the isotope levels of oxygen).
