Does temperature affect calories burnt?

HereLieWe

Today, I went on a midday hike. I walked for an hour and thirty minutes in 102 °F weather. Probably not a good idea, I know, but I'm adjusted to the heat, I wore sunblock, and I brought plenty of water. Along the way, it occurred to me that perhaps the heat has an affect on calories burnt. Which is why I ask you this: would I burn more or less calories walking in 102 °F weather versus 70 °F or 30 °F, provided I move at an identical pace and over identical terrain in each scenario?

It's negligible at most.

It won't make enough difference to do anything. Your body has to burn calories to keep your core temp at 98 degrees so if it's cold you will burn slightly more to stay warm, but like I said in the grand scheme it's negligible

Not enough to care.

Plus I'm fairly sure you burn more during colder than usual temps, not warmer, so you wouldn't be getting those bonus calories you're looking for anyway

Thank you for your help everyone. (:
