"Thermogeddon" is generally (by me) deemed to be a time series temperature graph showing runaway positive feedback - something rather like the infamous "hockey stick", which was in fact contrived to demonstrate exactly this.
It is this particular "feature" of global temperature which is the underlying thesis of the entire AGW community - the problem is that the observed data do not show this to be true in the satellite era, which is now well into its 4th decade.
.15C p.a. is slight, and an increase not inconsistent with what one would expect when observing the geological record.
What 'people' see though, is local changes in weather patterns, and being morons, they extrapolate this to the entire planet. This is what you are doing, when you imply that local changes have caused local fauna to adapt. It is also true as well where I happen to live, where the particular pollen to which I am allergic arrives earlier than it did 50 years ago. These are local events, they are not global events. It IS getting warmer, ever so slightly on average every year, and it will likely continue to do so until whatever causes ice ages happens again.
Warmer is better for life, we live in a benign climatic period in geological time.
You, and I, are so amazingly unlikely, that we should try to live and enjoy our one chance at this, and stop stressing about the universe doing what it does. Humanity didn't cause the last ice age (or end it) and it won't cause the next. Neither will it precipitate Thermogeddon.
