For the willfully ignorant out there:
"We see a cooling trend," said Martin Mlynczak of NASA's Langley Research Center in the September 2018 issue of the Journal of Atmospheric and Solar-Terrestrial Physics. "High above Earth's surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold."
Based on this NASA report in order for the Earth temperatures to rise requires a suspension of the second law of thermodynamics which states: Isolated systems spontaneously evolve towards thermal equilibrium.
Simply and in other words heat moves to cold.
