HEATING UP: The Earth is the hottest it has been in 2,000 years.
SCIENTISTS AGREE: The National Academy of Sciences studied tree rings, corals and other natural formations, in part, to conclude that the heat is unprecedented for potentially the last several millennia.
HUMAN FAULT: Human activities are responsible for much of the recent warming, the Academy says.
QUOTE: “Surface temperature reconstructions for the last 2,000 years are consistent with other evidence of global climate change…”
“…and can be considered as additional supporting evidence. In particular, the numerous indications that recent warmth is unprecedented for at least the last 400 years and potentially the last several millenia, in combination with estimates of external climate forcing variations over the same period, supports the conclusion that human activities are responsible for much of the recent warming.” – Surface Temperature Reconstructions for the Last 2,000 Years, a report Thursday from the National Academy of Sciences.”
