No. Many of the instruments are "passive" - meaning they don't emit any energy Earthward; they only "listen" or "take pictures". "Active" sensors will emit a signal and wait to record the characteristics of its "echo." The amounts of energy involved in active sensors are miniscule compared to the factors that determine temperature on the Earth - namely the Sun's energy, and the ways that the atmosphere and ocean systems transport it around.
