Note that an individual snapshot like this should not be used as evidence in any debate about climate. The differences from average that you see here are mostly due to seasonal conditions, e.g. an abnormally warm or cool season. These snapshots are pieces in a larger puzzle. To understand climate change we need to analyse these data snapshots over many years.
Data for this map comes from NASA's Terra satellite. You can see where this satellite is right now on the Terra orbit tracking page.
