It’s a known fact that today or modern lifestyle is causing Global Warming. (Al Gore isn’t helping either what with his jet-set lifestyle, but I digress…)
What isn’t so well known is that heavy use of fossil-fuel burning cars way back in the Middle ages contributed to the warm time they had back then too.
The findings prove that the world had a medieval warm period between the ninth and 14th centuries, with world temperatures significantly higher than today’s.
They also confirm claims that a little Ice Age set in about 1300, during which the world cooled dramatically. Since 1900, the world has begun to warm up, but has still to reach the balmy temperatures of the Middle Ages.
I get seriously sick of people who promote theories that have been disproven by facts.
