On January 21, 2015, Inhofe returned to chairing the Senate Committee on Environment and Public Works as part of a new Republican majority in the Senate.
In response to NOAA and NASA reports that 2014 had been the warmest year globally in the temperature record, he said, "we had the coldest in the western hemisphere in the same time frame", and attributed changes to a 30-year cycle, not human activities.
In a debate on the same day about a bill for the Keystone XL pipeline, Inhofe endorsed an amendment proposed by Senator Sheldon Whitehouse, "Climate change is real and not a hoax", which passed 98–1.
Inhofe clarified his view that "Climate is changing and climate has always changed and always will.
There is archaeological evidence of that, there is biblical evidence of that, there is historical evidence of that", but added, "there are some people who are so arrogant to think they are so powerful they can change climate."

On February 26, 2015, Inhofe brought a snowball to the Senate floor and tossed it before delivering remarks in which he said that environmentalists keep talking about global warming even though it keeps getting cold.
