Science Today

I think it is always important to remember that just because a species or a group of species survived through a past time period, it doesn't automatically stand to reason that they will survive through another. With time can come environmental change; and one or more factors may work together in a novel way to impact some organisms directly or indirectly in a way that they haven't been impacted before. A study like this calls other scientists to the table to do more investigating which is a good thing, I think, for all species.

One more point on the Lizard video: The hypothesis is ridiculous. Earth temperatures are not uniform, but vary by hour, season, altitude, and latitude. There are also trends from solar and oceanic cycles. Lizards have been here for millions of years and survived warm and cold periods. It was probably two or three degrees warmer about 6,000 years ago when the Sahara was lush and wet. How did lizards survive these enormous changes but are impacted by an alleged 0.4 C change since the late 1970’s? The Academy should be embarrassed by lending its name to this absurd video.

Before the Academy spreads global warming propaganda perhaps some scientific analyses would be in order. This is a study based on 30 year old field notes that found a decline in lizards: To quote the study: “These are protected areas, so the habitat’s still there. So you start to think there is something else going on.”

Yes, something else is going on: the popularity of keeping lizards as pets. Here are some refereneces for you to consider.
