the warming and cooling is all natural...to say its 'human caused' is not an accurate statement
the earth in it's 4 billion years has had like 2 dozen warming and cooling cycles..the last ice age peaked around 16000-18000 years ago and we have been warming since...its not a steady warming, there are decades were it levels off, or even cools slightly, but we have been warming for the last 16000 years
each inter-glacial period, has brought the GLOBAL average temperature to the low-mid 70's F....currently we are around 59'f for a global average, and slightly behind the pervious cycles.
only people who deny history and science , are the ones calling it man made.
