Does "global warming" mean it’s warming everywhere? According to NOAA the answer is NO. “Global warming” means Earth's average annual air temperature is rising, but not necessarily in every single location during all seasons across the globe. Temperature trends across the entire globe aren’t uniform because of the diverse geography on our planet. We have oceans versus continents, lowlands versus mountains, forests versus deserts versus ice sheets and natural climate variability. Full story by NOAA here: http://goo.gl/Sn0trM
Observed trend in temperature from 1900 to 2012; yellow to red indicates warming, while shades of blue indicate cooling. Gray indicates areas for which there are no data. There are substantial regional variations in trends across the planet, though the overall trend is warming. Map from FAQ appendix of the 2014 National Climate Assessment.
