How Animal Behavior could put a new spin on the idea of Global Warming

Is the past the only key to telling the facts about Global Warming? Isn't there a big key missing? I believe animal behavior can tell a lot about what is going around us. Animals like the frogs are natural thermontors which are tens time more sensitive to heat then we our. Is it really a coincidence that larger numbers of frog species are disappearing due to temperture rise? Or bees who are very sensitive to ultra violet light ,not being able to follow migration patterns due to dramatic cold and warm periods of weather , which also can be linked with Global Warming. Should these indicators of Global Warming be forgotten? In the past didn't animals have certain traits that they evolved into in order to survive , that for the most part could not collaborate with our current time. Which could make it possible that maybe this increase in heat is different from the past. Is it possible that maybe tempertures are increasing so fast for certian wildlfe that they can't evolve and create survial techinques in time? Scientists have found that certain aquatic life in parts of Africa are migrating to cooler parts earlier for survival. Yet for some animals like the polar bear , who live under the most rigid conditions of cold can't possibly cooperate with the heat in such a sucessive rate. Thus maybe the past doesn't hold all the answers maybe the animals that are suffering now should be enough to sufice.
