ExxonMobil statement
The earth has experienced a warming trend in global surface air temperatures during the twentieth century, but the cause of this trend and whether it is abnormal remain in dispute. Although recent temperatures are elevated, they are not unprecedented in the geological record, which shows considerable variation as well as previous periods that were as warm as or warmer than today.
