Carbon dioxide drastically affected Earth's climate in the distant past.
A new study shows Earth’s temperature plunged to 40 degrees
below zero – in Florida, Egypt and other lands near the planet’s
supposedly warmer equatorial regions during a radical climate shift
known as 'Snowball Earth.'
The jostling of the giant planets Jupiter and Saturn in the
solar system’s early days may have delivered a Mercury-type building
block to baby Earth, providing the planet with the chemistry to heat its
convecting, liquid metal core to this day
