Thank you! Clearly the map maker has never been to Las Vegas and Los Angeles in the summer. VASTLY different. There's a reason LA is the second biggest city in America and the weather is a huge part of it. Surfing weather vs Death Valley lite.
And I doubt that they have been to Spain. Central Spain is -5º in the winter to 40º+ in the summer, and dry AF. Central Spain is a plateau, elevation 700m, so it has no buffering from the coast. I very much doubt you'd have that in a coastal region.
Idk where you're getting those numbers from nor do I have the data this map was made from but that part of Australia is arid, it can easily get up to 40 in summer and there are definitely parts of it that get down to -5 in winter
What do you mean, they would obviously be measuring in terms of ranges of climates not specific climates and if you consider the size of the shaded regions it makes total sense that the variety of climates experienced in the region is similar to the variety of climates in la/Nevada. It would be unhelpful for a map of this size to have 1000 different regions all hyper specific. Large regions of Australia compared to large regions of other places
Los Angeles is not a desert. Los Angeles has
an enormous agriculture industry surrounding the area - farms don't work well in a desert. LA is a type of savanna, specifically an oak savanna, compared to the high, dry desert of southern Nevada. It isn't a minor climate shift - they are two radically different environments. The only thing that they share in common is getting hot in the summer.
Okay? So the areas shaded experience a range of climates shared with Nevada and LA. Seems pretty reasonable considering the wide range of climates the map is representing. It would be unhelpful to have 1000 different shaded regions relating to 1000 different places. Also considering the size of the shaded area it's not exactly surprising that the climate range would be on that scale
