Actually you're kind of correct. Our measurement of the planet isn't complete. We don't have the ability to measure the movement of every molecule and get a perfect temperature measurement. So imagine all that extra energy swimming around. If it gets pushed into the deep ocean we have no way to measure that, but after a while it gets pushed to the surface and it looks like the temperature spiked as it also warms the atmosphere. So the temperature at the moment is actually always increasing but we have to average it over a longer period of time to iron out the gaps in our measurements.
