Global warming is a symptom of Earth’s energy imbalance, which is a measure of the difference between the total amount of heat reaching Earth from the sun, and the amount radiating back into space.

It's a natural warming event that adds to the global temperature, so it boosted it temporarily above that 1.5 Celsius mark. What we're really concerned about is when the trend line itself crosses ...
