This whole Global Warming is no different with people who feared evil spirits for their problems. Just replace it with Global Warming. They blame Global Warming for everything. By their thinking, I should blame the Great Ptarmigan/Rabbit War on Global Warming. Well, it is a war of extreme greed on the rabbit's part.
Earth's climate is ALWAYS going to change no MATTER WHAT. We have cool and warm phases because of combination of Earth's axis position, ocean current, and continental drifts. The Gulf Stream is what keeps most of Europe milder despite the fact they are at the same latitude as Canada, which much colder. We can't change our climate, only at the local level, but that is due to concrete heat island affect.
