On the topic of the weather getting hotter, if creatures can sustain changes in temperature between night and day orders of magnitudes larger than the alarmist "1 degree per century" I wouldn't worry about 1 degree of change. Nature is incredibly resilient and humans are the most ingenious part of nature when we're not fighting over what other people like to eat.
