‘…The whole planet is getting warmer, which means that temperature zones are shifting. Warmer areas are expanding, pushing cooler zones closer to the North and South Poles, so that the meadow, the forest, the tundra, the desert, the plains — wherever you live — your ecosystem is beginning to shift. Over the decades, the climate you prefer has started to migrate away from you, which raises an intriguing question: “If I’m standing in a landscape,” asked Stanford ecologist Scott Loarie a few years ago, “how far do I have to travel in order to change my temperature” – to get back to the climate that suits me? Loarie, Chris Field, and their colleagues at the Carnegie Institution for Science gathered all the data they could from climate change studies in order to measure “temperature velocity,” or, as Scott put it in a podcast at the time, “How fast is temperature change sweeping across the Earth’s surface?”
In 2009, they came up with an answer, published in the science journal, Nature. As a global average, they said, temperatures are changing at a rate of 0.42 kilometers — or roughly, a quarter mile a year, which means that if you are standing on a patch of earth, climate zones are moving at a rate (on average) of about 3.8 feet every day.’ (Krulwich Wonders… NPR).
