"The alarmists claim the world is still warming, that heat is building up in the oceans, and that the ocean temperature is rising and rising fast. These claims implicitly depend on a time period to say what a "trend" is, because temperatures fluctuate. The alarmists provide the context by showing trends of 20 to 50 years. This is a clever trick to reframe the debate, and essential to their case."
