The most accurate record we have of modern temperatures comes from satellites. Their readings are, in fact, the only transparent, uncorrupted temperature records in existence. Surface temperature records are unreliable because of siting issues, poor coverage of the oceans, failure to recognize the urban heat island effect, and deliberate falsification by alarmist climate scientists, who constantly revise temperatures recorded decades ago to make the past look cooler. The problem with satellite temperature data, of course, is that it only goes back to 1978.
