The colder an object's surroundings,
the faster the object will cool.
Newton's Law of cooling
states that the rate of cooling of an object is approximately proportional to the temperature difference between the object and its surroundings.
The near unanimous view of climate scientists,
is that human activity is a main driver of global warming and climate change.
is the warming of a planet's surface due to the trapping of radiation by the atmosphere.
