still a Global Warming skeptic

I have no idea whether or not YOU are destroying the Earth as claimed by Obama at the United Nations climate change summit. But arguments and statistics like the ones presented below, keep me skeptical

Doug L. Hoffman, author of the book The Resilient Earth (2009) …

Earth’s temperature is always changing.
Over time there have been periods when it has been colder than it is today.
For most of the Phanerozoic it has been much warmer than it is today.
Life has persisted during periods both hot and cold.
There is no one “right” temperature.
Carbon dioxide has always been present in Earth’s atmosphere.
Over time there have been periods when CO₂ has increased and decreased naturally.
For most of the Phanerozoic it has been much higher than it is today.
Life has persisted during periods with high CO₂ and low CO₂.
CO₂ levels will change with or without human contributions.
Over time there have been a number of ice ages—Life has endured multiple ice ages.
For most of the Phanerozoic there have been no persistent polar ice caps.

Those who say CO₂ is the most important factor in climate change, that human GHG emissions will cause runaway global warming, have no historical basis for such claims. …

Given 4 billion years of Earth history and 542 million years of complex life, blaming mankind for 9,000 years of global warming seems rather silly. …

Be safe, enjoy the interglacial and stay skeptical. …
