Today NASA launched a new satellite that will collect information for climate research and weather forecasting. Reporting on the satellite, CNN meteorologist Chad Meyers said "They want to be able to know whether the earth is actually getting warmer or is it getting colder":
Actually, we already know the answer to that question:
All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years.
In addition to those three surface temperature reconstructions, satellites have shown for decades that the earth is getting warmer. And just last week, an independent study using new methods confirmed the warming trend shown in the previous global surface temperature records. In fact, the response to the study by climate change contrarians was basically, "We never disputed that Earth is warming."
