Between the early to mid-Cretaceous, the world climate became warmer by as much as 10°C. Volcanoes were throwing ash and gas into the atmosphere, rapidly altering the climate. Sea levels fell in the final stage of the Cretaceous. Changes in climate would have occurred due to the disruption of wind and ocean currents.
Q. What was the atmosphere like during the Cretaceous period?
The atmosphere of the Earth 80 million years ago was discovered to have 50% more oxygen than modern air. Brenner and Landis found that for all gas samples taken from amber 80 million years old the oxygen content ranged between 25% to 35% and averaged about 30% oxygen. Cretaceous air was supercharged with oxygen.

Q. What was the temperature like during the Cretaceous period?
The Cretaceous, which occurred approximately 145 million to 66 million years ago, was one of the warmest periods in the history of Earth. The poles were devoid of ice and average temperatures of up to 35 degrees Celsius prevailed in the oceans.
Q. Why was the Cretaceous so warm?
The huge amount of carbon dioxide created from this volcanic activity is believed to be the main reason for the Cretaceous Period being so warm. The most extreme was the earth’s climate in the Upper Cretaceous Period (86 million years ago), which was far warmer than today.
